For a growing UK company, hiring overseas talent can solve a genuine business problem.
Perhaps you cannot find the right software engineer in the UK. Maybe your company is expanding into a specialist market and needs experienced managers. Perhaps you already have international employees and need a compliant sponsorship system that can keep pace with growth.
In each situation, a UK sponsor licence can become an important part of the business’s recruitment strategy.
But getting a sponsor licence is not simply about completing an online application and paying a fee.
A company must show that it is a genuine organisation operating lawfully in the UK, has appropriate people and systems to manage sponsorship, can carry out its sponsor duties and intends to sponsor eligible workers in eligible roles. UKVI can also conduct compliance checks, including visits to the business.
This is why choosing the best sponsor licence advisors for medium UK companies is less about finding the cheapest adviser and more about finding someone who understands the company’s structure, workforce, HR systems, recruitment plans and long-term sponsorship obligations.
For medium-sized businesses, this matters even more.
A growing company may have several departments, multiple offices, remote workers, international recruitment plans and an HR system that was never designed specifically around immigration compliance.
A specialist sponsor licence adviser can help bring those pieces together.
This guide explains what medium-sized UK businesses should look for in a sponsor licence adviser, how the 2026 rules affect employers, what sponsorship costs, what the application involves, what happens after approval and how to build a sponsorship system that remains compliant as the company grows.
What is a UK sponsor licence?
A UK sponsor licence allows an eligible organisation to sponsor workers who require immigration permission to work in the UK.
For employers, the relevant routes can include the Worker routes, such as Skilled Worker, and certain Temporary Worker routes.
GOV.UK states that employers will usually need a sponsor licence to employ someone from outside the UK who needs sponsorship. This includes qualifying citizens of the EU, Iceland, Liechtenstein, Norway and Switzerland who arrived in the UK after 31 December 2020. Certain people do not need sponsorship, including Irish citizens and people who already have settled or pre-settled status under the EU Settlement Scheme.
A sponsor licence does not mean that every overseas worker will automatically receive a visa.
The employer must still:
- Have an appropriate sponsor licence;
- Offer an eligible job;
- Meet the relevant salary requirements;
- Assign the correct Certificate of Sponsorship;
- Comply with sponsorship rules; and
- Continue meeting its sponsor duties.
The worker must independently satisfy the immigration requirements for the route.
That distinction is important.
Why medium UK companies need specialist sponsor licence advice
A very small company may have one director handling recruitment, HR, payroll and compliance.
A large multinational may have a dedicated immigration team, internal legal department and specialist HR compliance staff.
Medium-sized businesses often sit somewhere between the two.
They have enough employees and operational complexity to create sponsorship risks, but may not have an in-house immigration team.
That creates a particular need for specialist advice.
1. The company may be growing quickly
A business can move from sponsoring one employee to sponsoring 10, 20 or 50 workers surprisingly quickly.
The processes that work for one sponsored employee may become unreliable when the workforce expands.
2. HR systems may not be immigration-ready
A company may have a good HR system but still lack a structured process for:
- Immigration expiry dates;
- Right to work checks;
- Sponsored-worker absences;
- Job changes;
- Salary changes;
- Reporting obligations;
- Employee contact details;
- Record keeping.
3. Several people may manage sponsorship
The Home Office requires sponsor licence key personnel.
These roles include the Authorising Officer, Key Contact and Level 1 User.
From September 2026, businesses can no longer appoint new Level 2 Users. Existing Level 2 Users must either be upgraded where eligible or deactivated by March 2027. Mandatory multi-factor authentication for Sponsorship Management System users was introduced from 3 September 2026.
For a medium-sized company, these changes should be built into its internal sponsorship plan.
What makes the best sponsor licence advisors for medium UK companies?
There is no official government ranking of the “best sponsor licence advisors”.
A company should therefore assess advisers based on their experience, regulatory knowledge, service model and ability to support the business beyond the initial application.
The strongest adviser is usually not simply the person who promises to complete the form.
It is the adviser who understands what happens after the licence is granted.
Here are the most important factors.
1. Specialist sponsor licence experience
Sponsor licensing is a specialist area of UK immigration law.
An adviser should understand:
- Sponsor licence eligibility;
- Skilled Worker sponsorship;
- Temporary Worker routes;
- Certificates of Sponsorship;
- Sponsor management systems;
- Compliance visits;
- Reporting duties;
- Record keeping;
- Right to work;
- Immigration skills charge;
- Sponsor licence ratings;
- Licence suspension and revocation risks.
The adviser should also understand how these requirements affect the employer’s day-to-day operations.
This is particularly important for medium-sized companies because sponsorship can involve several departments.
2. Experience with businesses of a similar size
A sponsor licence adviser working primarily with individual visa applicants may not be the right choice for a company with 300 employees.
The needs are different.
A medium-sized employer may require advice on:
- Organisational structure;
- HR systems;
- Recruitment processes;
- Multiple locations;
- Overseas recruitment;
- Internal mobility;
- Sponsored-worker transfers;
- Compliance audits;
- Management responsibilities;
- Future workforce planning.
The adviser should therefore be able to demonstrate experience advising employers rather than only individual migrants.
3. Strong understanding of compliance
This may be the most important factor.
A sponsor licence is not a one-time immigration application.
Once a company becomes a sponsor, it takes on continuing responsibilities.
The Home Office explains that sponsors must monitor sponsored workers, keep appropriate records, conduct right to work checks, track attendance, maintain contact information and report relevant problems to UKVI.
The Home Office can take compliance action where it believes a sponsor has failed to meet its responsibilities.
Possible consequences can include:
- Downgrading the licence;
- Suspension;
- Revocation;
- Restrictions on sponsorship; and
- Other enforcement action.
That makes compliance advice just as important as application advice.
4. Ability to audit your HR systems
A good adviser should be willing to ask uncomfortable questions.
For example:
Who checks the immigration status of your sponsored workers?
Where are right to work records stored?
Who knows when a visa expires?
Who reports changes to UKVI?
What happens when a sponsored employee is absent?
What happens if their salary changes?
Who updates the Sponsorship Management System?
Who is your Authorising Officer?
If nobody can answer these questions clearly, the company may have a compliance weakness.
The best sponsor licence advisors for medium UK companies should identify these issues before they become Home Office problems.
5. Understanding the company’s recruitment plans
The sponsor licence application should fit the company’s actual workforce strategy.
Suppose a technology company expects to hire:
- Software developers;
- Data scientists;
- Project managers;
- Technical directors;
- Overseas specialists.
The adviser should help the company understand which roles may be suitable for sponsorship and which immigration routes may be relevant.
The Home Office expects sponsors to demonstrate that they can and genuinely intend to offer employment meeting the relevant immigration requirements.
This means a sponsor licence should not be treated as a general-purpose permission to employ anyone from overseas.
Best Sponsor Licence Advisors in the UK: Comparison Guide
The following firms are worth considering when a UK business is looking for professional support with sponsor licence applications, Skilled Worker sponsorship, compliance and ongoing sponsor management. This is an informational shortlist, not an official ranking by the UK Government or Home Office. Companies should compare the adviser’s experience, regulatory status, service scope, pricing and suitability for their specific workforce requirements.
| Sponsor Licence Advisor | Best Suited For | Key Sponsor Licence Services | Why Consider Them? |
|---|---|---|---|
| AYJ Solicitors | SMEs and medium-sized UK businesses | Sponsor licence applications, Skilled Worker sponsorship, compliance advice, sponsor licence support and business immigration | Specialist immigration support with services suited to businesses that need practical guidance through sponsorship and compliance |
| Russell-Cooke | SMEs, established businesses and larger organisations | Sponsor licence applications, sponsored visas, compliance, licence downgrading/revocation and enforcement matters | Business immigration team advises organisations across different sizes and sectors, including sponsor compliance and enforcement matters |
| Carter Thomas Solicitors | Technology companies, start-ups and established businesses | Sponsor licence applications, compliance testing, training, strategic sponsorship advice and immigration support | Focuses heavily on business immigration and offers sponsor licence compliance testing and training |
| OTS Solicitors | Businesses needing ongoing sponsor management | Sponsor licence applications, sponsorship management, SMS support, compliance and ongoing licence management | Offers ongoing sponsorship management support, including assistance with key personnel and sponsor-management responsibilities |
| Irwin Mitchell | Larger businesses and organisations with complex requirements | Sponsor licence applications, compliance, appeals and wider business immigration | Larger legal practice with business immigration capability and support for organisations dealing with more complex immigration requirements |
| Compass Law | SMEs and businesses wanting practical compliance support | Sponsor licence applications, mock audits, compliance, suspension support and licence management | Offers application and compliance services, including mock Home Office audits and assistance where a licence is suspended |
| Visa Professionals | Employers wanting solicitor-led immigration support | Sponsor licences, Skilled Worker sponsorship, Global Business Mobility, compliance and retained employer support | Solicitor-led and IAA-regulated immigration advice with dedicated employer and sponsor-licence services |
Important: The firms above should not be interpreted as an official “top 7” ranking. Their inclusion is based on publicly available information about their sponsor licence and business immigration services. For example, Russell-Cooke states that it advises sponsors of different sizes and sectors, while Carter Thomas offers sponsor licence advice, compliance testing and training. OTS, Irwin Mitchell, Compass Law and Visa Professionals also publicly describe sponsor-licence or employer immigration services.
What Should a Medium-Sized Company Look For?
Rather than choosing an adviser solely because they appear in a “best” list, a business should check whether the adviser can help with the full sponsorship lifecycle:
- Sponsor licence eligibility and application
- Supporting-document preparation
- Authorising Officer and Level 1 User requirements
- Skilled Worker sponsorship
- Certificate of Sponsorship advice
- HR and right-to-work procedures
- Sponsor Management System support
- Home Office compliance preparation
- Mock compliance audits
- Licence downgrading or suspension issues
- Changes to the business or sponsored workforce
- Ongoing sponsor compliance
This is particularly important because sponsor duties continue after a licence has been granted. The Home Office can downgrade, suspend or revoke a licence where sponsorship responsibilities are not properly maintained.
Sponsor licence requirements for medium UK companies
Before applying, a business needs to establish that it is eligible.
The Home Office looks at whether the organisation:
- Is genuine;
- Operates lawfully in the UK;
- Meets suitability requirements;
- Has appropriate key personnel;
- Has suitable HR systems;
- Intends to sponsor eligible workers;
- Can comply with sponsor duties.
Supporting evidence is important.
The Home Office says that the documents submitted should demonstrate that the business exists and is genuine, operates lawfully, meets route-specific requirements and is able and intends to sponsor workers in eligible roles. Missing mandatory documents can result in an application being rejected or refused.
Medium company does not necessarily mean “medium sponsor”
This is a common misunderstanding.
Businesses often describe themselves commercially as:
- Small;
- Medium-sized;
- Large;
- Enterprise.
The Home Office sponsor-fee structure is different.
For sponsorship fees, an organisation generally qualifies for the small sponsor fee if it meets the applicable small-company criteria. Otherwise, the large sponsor fee applies.
For the Immigration Skills Charge, GOV.UK defines a small sponsor differently through a test based on financial and employee criteria. A business is usually small if at least two of the following apply:
- Annual turnover of £15 million or less;
- Total assets of £7.5 million or less;
- 50 employees or fewer.
If the business does not meet the small-sponsor criteria, the medium or large rate can apply for the Immigration Skills Charge.
Therefore, a business should not decide its sponsor fee simply because it calls itself a “medium company”.
The exact Home Office classification needs to be checked.
Sponsor licence fees for medium UK companies in 2026
From 8 April 2026, the Worker sponsor licence fee for a large sponsor is £1,682.
The small sponsor fee is £611.
The same £1,682 large fee applies to several combinations of Worker and Temporary Worker/Student sponsorship.
The October 2026 Home Office fee table confirms that the Worker large-sponsor fee remains £1,682 from 8 October 2026.
Other sponsorship costs
The business may also need to budget for:
- Certificate of Sponsorship fees;
- Immigration Skills Charge;
- Priority services;
- Professional adviser fees;
- Compliance support;
- Visa-related costs where the employer is responsible for them.
The Skilled Worker Certificate of Sponsorship fee is currently £525.
Immigration Skills Charge for medium and large sponsors
This can become a significant cost for growing companies.
For medium and large sponsors, the Immigration Skills Charge is currently:
£1,320 for the first 12 months
and
£660 for each additional six months.
The charge applies to relevant Skilled Worker and Senior or Specialist Worker sponsorship unless an exemption applies.
For a five-year sponsorship, the maximum charge for a medium or large sponsor can therefore reach:
£6,600.
That is per sponsored worker where the charge applies.
For a company planning to sponsor several employees, this needs to be included in workforce budgeting from the beginning.
Who pays sponsor licence costs?
The employer is responsible for the relevant sponsor licence and sponsorship costs.
There are also specific restrictions on recovering certain sponsorship costs from sponsored workers.
The Home Office states that sponsors can face licence revocation if they recoup, or attempt to recoup, specified sponsor licence fees, Certificate of Sponsorship fees or Immigration Skills Charge costs from workers.
This is another reason why HR, payroll and finance teams should understand the sponsorship process.
A mistake in cost allocation can become an immigration compliance issue.
How long does a sponsor licence application take?
Most sponsor licence applications are dealt with in less than eight weeks.
UKVI may need to visit the business before making a decision.
Eligible employers may be able to use the priority service.
The current priority fee is £750, and eligible applications are generally considered within 10 working days.
However, priority processing does not guarantee approval.
This distinction matters.
Paying £750 buys faster consideration.
It does not buy a successful outcome.
Should a medium company use the priority service?
It depends on the business.
Priority processing may be useful if:
- An important international hire is waiting;
- A business launch depends on a specialist employee;
- An employee’s existing immigration permission creates a tight deadline;
- The company has planned recruitment around a specific start date.
But there is little value in rushing an incomplete or poorly prepared application.
A strong adviser should first make sure the application is ready.
Then consider whether priority processing makes commercial sense.
The sponsor licence application process
A typical process involves several stages.
Stage 1: Assess eligibility
Review:
- Company structure;
- Trading activity;
- HR systems;
- Key personnel;
- Previous immigration issues;
- Proposed workers;
- Routes required.
Stage 2: Select the licence routes
The business should decide whether it needs:
- Worker routes;
- Temporary Worker routes;
- Skilled Worker sponsorship;
- Senior or Specialist Worker;
- another relevant route.
The choice should reflect the actual workforce plan.
Stage 3: Appoint key personnel
The company needs appropriate people to manage the licence.
The main roles include:
- Authorising Officer;
- Key Contact;
- Level 1 User.
The Home Office requires the Authorising Officer to be an eligible person within the organisation. At least one Level 1 User must meet specified employment and status requirements.
Stage 4: Prepare evidence
The company prepares the required supporting documents.
Stage 5: Submit the application
The application is completed online and the appropriate fee is paid.
Stage 6: Compliance checks
UKVI may contact the business or visit the premises.
Stage 7: Decision
If successful, the organisation receives its sponsor licence and access to the Sponsorship Management System.
What happens during a Home Office compliance visit?
A compliance visit should not be viewed as something that only happens to companies suspected of wrongdoing.
UKVI can conduct checks as part of assessing an application or monitoring an existing sponsor.
The Home Office guidance explains that compliance checks can assess areas including:
- HR systems;
- Immigration compliance;
- Employment;
- Relevant convictions or civil penalties;
- Whether the business genuinely intends to employ eligible workers.
This means the company should be able to demonstrate that its policies actually operate in practice.
Having an impressive HR policy document is not enough if nobody follows it.
Sponsor licence compliance after approval
Getting the licence is the beginning.
The company must continue complying with sponsor duties.
These include monitoring sponsored workers and keeping appropriate records.
The Home Office requires sponsors to maintain systems that enable them to:
- Monitor immigration status;
- Keep relevant documents;
- Record attendance;
- Maintain contact details;
- Identify problems;
- Report relevant issues to UKVI.
The company also needs to report significant changes to its own circumstances.
For example, certain business changes must be reported within 20 working days. These can include stopping trading, insolvency, substantial changes to the nature of the business, mergers and takeovers.
This is why ongoing sponsor compliance should have a named owner inside the business.
The 2026 Sponsorship Management System changes
Medium UK companies should pay particular attention to the Sponsorship Management System changes introduced in 2026.
From 3 September 2026, multi-factor authentication became mandatory for SMS users.
From 9 September 2026, businesses can no longer appoint new Level 2 Users.
Existing Level 2 Users who still need access must be upgraded to Level 1 Users if eligible, or their accounts must be deactivated.
The Home Office states that existing Level 2 accounts will be automatically deactivated after 8 March 2027.
For businesses with several HR or immigration administrators, this should be reviewed immediately.
Why compliance technology matters for medium companies
A company sponsoring five workers may manage immigration information manually.
A company sponsoring 30 workers should think differently.
It should consider structured processes for:
Immigration expiry tracking
Record:
- Visa expiry;
- Passport expiry;
- Right to work status;
- Follow-up dates.
Absence monitoring
Attendance information should be accessible.
Document storage
Keep relevant sponsorship records in an organised and secure system.
HR change management
A change in:
- Salary;
- Occupation;
- Work location;
- Working hours;
- Job duties;
- Employment status
may need immigration consideration.
Reporting calendar
Create reminders for relevant sponsor reporting obligations.
A good adviser should help the business design these systems rather than simply explain them after a compliance problem appears.
Choosing the best sponsor licence advisors: questions to ask
Before appointing an adviser, ask:
“How many sponsor licence applications do you handle?”
You want evidence of relevant experience.
“Do you advise companies after the licence is granted?”
This is important.
“Can you review our HR systems?”
A sponsor licence adviser should understand practical compliance.
“Can you support us during a Home Office compliance visit?”
This can be valuable for businesses that do not have internal immigration expertise.
“Can you advise on Certificates of Sponsorship?”
The adviser should understand the full sponsorship lifecycle.
“Can you advise on sponsor licence changes?”
Businesses change.
Your adviser should be able to help with:
- Additional routes;
- Key personnel;
- Business restructuring;
- Mergers;
- Acquisitions;
- Changes in circumstances;
- Compliance issues.
“Who will actually handle our case?”
A company should know whether it will work directly with an experienced immigration professional or mainly with an administrative team.
Should you choose a solicitor or an immigration consultancy?
There is no universal answer.
The right choice depends on the complexity of the business and the type of support required.
For straightforward administrative support, a regulated immigration adviser may be suitable where they are authorised to provide the relevant services.
For businesses dealing with complicated corporate structures, immigration problems, compliance concerns, mergers, employment issues or potential enforcement action, a specialist immigration solicitor may provide a broader legal service.
The important point is to check that the adviser is appropriately regulated and authorised to provide the service being offered.
Do not choose an adviser solely because the website says “best”, “expert” or “guaranteed approval”.
No legitimate adviser can guarantee that UKVI will approve a sponsor licence.
Red flags when choosing a sponsor licence adviser
Be cautious if an adviser:
- Guarantees approval;
- Promises a licence without reviewing your business;
- Offers an unusually low fixed price without explaining what is included;
- Does not ask about HR systems;
- Does not discuss compliance;
- Cannot explain sponsor duties;
- Tells you that sponsorship is simply a form-filling exercise;
- Suggests transferring prohibited sponsorship costs to workers;
- Does not explain the Home Office classification of your business;
- Cannot explain who will manage your case.
A professional adviser should be willing to explain both the opportunities and the risks.
How the best sponsor licence advisors support business planning
The strongest sponsorship strategy begins before recruitment.
Imagine a medium-sized engineering company planning to hire 15 international engineers over the next 24 months.
Instead of applying for a sponsor licence only when the first candidate accepts an offer, the company can build a two-year sponsorship plan.
Phase 1: Business assessment
Identify:
- Current workforce;
- Skills shortages;
- Expected vacancies;
- International recruitment;
- Business expansion;
- Locations;
- HR capacity.
Phase 2: Immigration assessment
Identify:
- Which roles may be eligible;
- Salary considerations;
- Relevant occupation codes;
- Likely immigration routes;
- Expected sponsorship costs.
Phase 3: Compliance infrastructure
Build:
- Right to work procedures;
- Absence monitoring;
- Immigration expiry tracking;
- Document retention;
- Reporting procedures;
- Responsibility matrix.
Phase 4: Sponsor licence
Prepare and submit the licence application.
Phase 5: Recruitment
Use the licence to sponsor appropriate workers where the immigration requirements are met.
Phase 6: Ongoing review
Review compliance regularly rather than waiting for a Home Office visit.
This approach turns sponsorship into a business process instead of an emergency recruitment solution.
The financial impact of getting sponsorship wrong
The cost of professional advice can look significant when compared with the sponsor licence fee.
But businesses should also consider the potential cost of getting sponsorship wrong.
A company could face:
- Recruitment delays;
- Lost candidates;
- Visa problems;
- Compliance investigations;
- Licence downgrading;
- Suspension;
- Revocation;
- Disruption to sponsored employees;
- Additional legal costs.
For a company dependent on specialist international workers, losing its sponsor licence could have a much greater commercial impact than the original application fee.
This is why the best sponsor licence advisors should be viewed as part of risk management rather than simply an application expense.
Benefits of using specialist sponsor licence advisors
Better application preparation
A specialist can identify weaknesses before submission.
Reduced administrative mistakes
Correct documentation and consistent information can reduce avoidable problems.
Stronger compliance
The business can establish systems before sponsoring workers.
Better workforce planning
Immigration requirements can be incorporated into recruitment plans.
Faster response to changes
When the rules change, the company has someone monitoring the immigration implications.
Support during compliance checks
The business can prepare for UKVI scrutiny rather than reacting to it.
Reduced management burden
HR teams can focus on recruitment and employees while immigration specialists support the regulatory side.
Future-proofing sponsorship for 2027 and beyond
The sponsorship system is becoming increasingly digital.
The 2026 changes to SMS access and authentication demonstrate this direction.
Businesses should therefore avoid building sponsorship processes around one individual.
If the only person who understands the sponsor licence leaves the company, the business should still be able to operate the system.
Create:
- Documented processes;
- Backup users;
- Clear responsibility;
- Internal training;
- Compliance calendars;
- Central document management;
- Regular audits.
The Home Office’s 2026 guidance also makes clear that sponsor licence holders must keep themselves informed of the relevant sponsor guidance, which is subject to change.
In practical terms:
Do not build a sponsorship system that works only under today’s rules. Build one that can be updated when the rules change.
How often should a medium company review sponsor compliance?
There is no universal government timetable requiring every business to conduct a particular internal audit every month or quarter.
But regular internal reviews are sensible.
A medium-sized employer could consider:
Monthly
Review:
- Visa expiry dates;
- New sponsored employees;
- Leavers;
- Absences;
- Right to work records.
Quarterly
Review:
- Sponsorship records;
- Reporting procedures;
- HR changes;
- Salary changes;
- Job changes;
- SMS access.
Annually
Conduct a wider sponsor compliance audit.
Review:
- Policies;
- Records;
- Key personnel;
- HR systems;
- Reporting;
- Recruitment processes;
- Training;
- Upcoming immigration changes.
The precise structure should reflect the size and complexity of the organisation.
What if your company already has a sponsor licence?
You may not need a completely new licence.
Instead, you may need advice on maintaining or improving the existing one.
A specialist adviser can review:
- Current licence rating;
- Sponsored workers;
- CoS records;
- Key personnel;
- SMS access;
- HR systems;
- Previous UKVI correspondence;
- Compliance history;
- Upcoming business changes.
This can be particularly useful before:
- A merger;
- Acquisition;
- Company restructuring;
- Rapid international recruitment;
- Opening a new location;
- Changing HR systems;
- Transferring sponsored workers;
- A compliance visit.
Why medium UK companies should not wait for a problem
One of the biggest mistakes is contacting an adviser only after receiving a Home Office compliance notice.
By that point, the company may already have a problem.
A better approach is preventive.
If you know that international recruitment will become important to your business, start planning before you need your first Certificate of Sponsorship.
If you already have a licence, review your systems before the business grows.
If your company has recently undergone restructuring, check whether the changes affect sponsor reporting.
If your SMS users have not been reviewed following the 2026 changes, do that now.
A practical sponsor licence checklist for medium UK companies
Before applying, ask:
Business
- Is the company genuinely operating in the UK?
- Is it lawfully trading?
- Can it provide the required evidence?

- Who will be the Level 1 User?
- Do the nominated people meet the requirements?
HR
- Can the company monitor attendance?
- Can it track immigration status?
- Can it retain relevant records?
- Can it conduct right to work checks?
Recruitment
- Which jobs need sponsorship?
- Are the jobs eligible?
- Are salary requirements understood?
- How many workers may be sponsored?
Finance
- Have sponsor licence fees been budgeted?
- Have CoS costs been considered?
- Has the Immigration Skills Charge been included?
- Is professional advice budgeted?
Compliance
- Who will report changes?
- Who monitors visa expiry?
- Who handles sponsored-worker changes?
- Who will respond to UKVI?
Technology
- Are SMS users correctly configured?
- Has MFA been implemented?
- Have Level 2 Users been reviewed?
- Are inactive users removed or updated?
Frequently Asked Questions
Who are the best sponsor licence advisors for medium UK companies?
There is no official government ranking of the best sponsor licence advisers. A strong adviser should have relevant employer-side immigration experience, understand sponsor compliance, be properly regulated where required and provide support beyond the initial application.
Does a medium-sized UK company need a sponsor licence?
If the company wants to employ workers who require sponsorship, it will generally need an appropriate sponsor licence unless an exemption applies. EU citizens who arrived in the UK after 31 December 2020 may require sponsorship if they do not have another immigration status giving them the right to work without sponsorship.
How much is a UK sponsor licence for a medium company?
The Home Office does not simply use a “medium company” sponsor fee category. If the business does not qualify as a small or charitable sponsor, the Worker sponsor licence fee is generally the large-sponsor fee, currently £1,682.
How long does a sponsor licence take?
Most applications are dealt with in less than eight weeks. Eligible applicants may be able to use the £750 priority service, which aims to consider an application within 10 working days, subject to the service rules and availability.
Does priority service guarantee sponsor licence approval?
No. Priority service speeds up consideration. It does not guarantee that the application will be approved.
How much is the Immigration Skills Charge for a medium-sized company?
For medium and large sponsors, the Immigration Skills Charge is currently £1,320 for the first 12 months and £660 for each additional six months where the charge applies.
Can a solicitor manage our sponsor licence?
A UK-based legal representative can be appointed as a Key Contact and, after the licence is granted, can also be appointed as a Level 1 User where the requirements are met.
Can an adviser guarantee a sponsor licence?
No reputable adviser should guarantee approval. UKVI makes the decision and can assess the company’s eligibility, suitability, HR systems, documents and proposed sponsorship activity.
What happens if a sponsor fails to comply?
UKVI can take compliance action, which can include downgrading, suspension or withdrawal of the sponsor licence.
Can our HR team manage sponsorship internally?
Yes, provided the company has suitable people, systems and processes and meets the Home Office requirements. External immigration support can still be useful for complex cases, audits, policy changes and compliance work.
What are the 2026 SMS changes companies should know?
Multi-factor authentication became mandatory for SMS users from 3 September 2026. New Level 2 Users can no longer be appointed from 9 September 2026, and existing Level 2 Users need to be upgraded if eligible or deactivated by the relevant deadline in March 2027.
Final thoughts: choosing the best sponsor licence advisors for medium UK companies
For a medium-sized UK company, choosing the best sponsor licence advisors should not be about finding the adviser with the biggest marketing claims.
It should be about finding someone who understands your business.
The right adviser should be able to look at the complete picture:
Business structure → HR systems → Recruitment → Sponsor licence → Certificates of Sponsorship → Worker compliance → Reporting → Long-term planning
That is the real sponsorship journey.
A sponsor licence gives a business an important ability to recruit international talent, but it also creates responsibilities.
The Home Office expects sponsors to operate responsibly, maintain suitable systems and comply with immigration and wider UK law.
For a growing company, that should not be seen simply as a regulatory burden.
It can become part of a well-managed international recruitment strategy.
The businesses that plan early tend to be in a much stronger position.
They know who manages the licence.
They know what records need to be kept.
They understand the costs.
They know when changes must be reported.
They prepare their HR systems before sponsorship begins.
And they review their processes as the company grows.
If your business is considering its first sponsor licence, expanding an existing licence or reviewing its sponsorship compliance, specialist employer-side immigration advice can help you identify the requirements before they become a problem.
