UK sponsor licence compliance support 

SMS reporting, staff file and salary audits, and Home Office inspection readiness — ongoing support to help you keep an A-rating and keep hiring overseas talent

10 working days to report changes
up to £60,000 fine per illegal worker
2 B-ratings before revocation

Sponsor licence compliance support is ongoing legal help for employers that already hold the right to hire overseas workers. Its purpose is to make sure the business reports changes through the Sponsorship Management System (SMS) on time, keeps the required records, pays sponsored workers at least the required minimum and is ready for a Home Office inspection at any moment. These duties decide whether a company keeps its licence and the ability to assign new certificates of sponsorship.

What sponsor licence compliance support is and why employers need it

A sponsor licence allows a UK business to assign certificates of sponsorship (CoS) and sponsor overseas workers for work visas, most often the Skilled Worker visa. Getting the licence is only the start. From the day it is granted, the business becomes a sponsor and takes on continuing duties to the Home Office: reporting changes, keeping records and monitoring the employment of every sponsored worker.

Since 6 April 2024, sponsors no longer need to renew their licence every four years: once granted, it remains valid for an indefinite period. For employers, this means there is no longer a formal “reset” every few years — compliance can be checked at any time, not only at renewal. The duties are set out in the official guidance Workers and Temporary Workers: guidance for sponsors, Part 3. The current version, 08/26, applies from 28 August 2026.

Getting a sponsor licence is only half the job — keeping it matters just as much. The licence no longer expires, so the Home Office can check a business at any time. Even one missed SMS report can lead to a downgraded rating. Imperial & Legal helps employers keep reporting, staff records and salaries in order, so that any inspection, planned or unannounced, does not come as an unpleasant surprise.

In practice, compliance support is most valuable for small and medium-sized businesses where sponsor duties sit with a director or a single HR manager. In larger groups, it often works as an independent audit: an outside adviser reviews internal processes and finds weak points before an inspector does. If a business is only planning to hire from abroad, the first step is to apply for a sponsor licence, with compliance support starting as soon as the licence is granted.

Benefits of seeking professional sponsor licence compliance support

  • Tracking of SMS reporting deadlines for every worker and the business
  • Audits of sponsored workers’ files against Appendix D requirements
  • Checks of salaries against certificates of sponsorship and thresholds
  • Right to work checks completed before each new worker starts
  • Preparation of key personnel for interviews with Home Office officers
  • Support with a downgraded rating, suspension or licence revocation
  • Guidance on fees and the ban on passing sponsorship costs to workers

Each of these points rests on a specific sponsor duty from the Home Office guidance. Below is what the business is actually required to do and where breaches happen most often.

Sponsor duties: what the Home Office expects from employers

In short, a sponsor must report changes, keep records, recruit only for genuine roles suitable for sponsorship, pay at least the salary stated on the certificate and make sure workers comply with their visa conditions. The guidance for sponsors groups these duties into several areas, and a breach of any of them can lead to a downgraded rating, suspension or revocation of the licence.

Key sponsor licence requirements under current Home Office rules

  • Reporting changes to sponsored workers to UKVI within 10 working days
  • Reporting changes to the sponsoring business within 20 working days
  • Record keeping for every sponsored worker in line with Appendix D
  • Right to work checks completed before employment begins
  • Payment of a salary no lower than the amount stated on the CoS
  • Employment only in a role that matches the assigned occupation code
  • No recovery from workers of fees that sponsors are barred from passing on

Responsibility for these duties lies with the key personnel the business appoints in the SMS. The Authorising Officer is a senior person responsible for the sponsor’s compliance overall. The Key Contact is the main point of contact for UKVI. Level 1 users work in the system day to day: they assign certificates, submit reports and update licence details. Problems with these roles are common in their own right — for example, when the Authorising Officer left the business long ago and nobody replaced them in the system.

Another core duty is to recruit only for genuine vacancies that are suitable for sponsorship. The worker’s job title and duties must match the occupation code on their certificate. If the actual work differs significantly from what was declared, the Home Office may treat this as a serious breach.

SMS reporting: which changes to report and when

The Sponsorship Management System (SMS) is the online system sponsors use to assign certificates and report changes to the Home Office. Most reports are tied to strict deadlines counted in working days, and missing a deadline is a breach in itself, even if nothing went wrong in substance.

EventReporting deadline
The worker does not start work on the expected start date10 working days
Absence without the employer’s permission for more than 10 consecutive working days10 working days
Unpaid or reduced-pay leave of more than 4 weeks in a year10 working days
Salary reduced below the level stated on the CoS10 working days
Significant changes to duties or the normal place of work10 working days
The business stops sponsoring the worker10 working days
New Authorising Officer or Key Contact, change of address, name or branches20 working days
Merger, takeover, change of ownership or insolvency procedure20 working days

Changes to the business’s details can take some time to process: according to GOV.UK, requests can take up to 18 weeks, while the priority service registers a change within 5 working days for £350. This matters when, for example, a business cannot assign an urgently needed certificate until a new Authorising Officer is in place.

In September 2026, the Home Office changed how sponsors access the SMS. Since 3 September 2026, multi-factor authentication has been mandatory for SMS users, and since 9 September 2026 sponsors can no longer add new Level 2 users, as this role is being phased out. Businesses that relied on Level 2 users for reporting should review who has access well in advance, so that reports continue to be submitted on time once older accounts are switched off.

Mandatory records: what to keep under Appendix D

The list of documents a sponsor must keep for each worker is set out in Appendix D to the sponsor guidance. The current version, 08/26, was published on 3 August 2026. Records can be kept on paper or electronically — what matters is that an officer can access them quickly.

The main groups of documents for each sponsored worker are:

  • evidence of the right to work check, including the result of the online eVisa status check;
  • recruitment records: job adverts showing the date of publication, and details of candidates and interviews where a formal labour market test was carried out;
  • the employment contract, payslips and evidence of the amount and frequency of all salary payments;
  • evidence of qualifications and professional registration where the role requires them;
  • up-to-date contact details: UK address, personal email and phone number, and a history of changes;
  • absence records.

Records must be kept for as long as the business sponsors the worker and then until the earlier of two dates: one year after sponsorship ends, or the date a compliance officer has examined and approved them. In practice, the most common gaps are missing copies of job adverts, outdated contact details and payslips that cannot be matched against the certificate.

A well-organised archive shortens inspections and reduces the risk of technical findings. That is why a records audit is usually the first step of compliance support: advisers check each worker’s file against Appendix D and draw up a list of missing documents.

The scope of support depends on the size of the business and the number of sponsored workers: one employer may only need a quarterly audit, while another needs an adviser who manages the SMS on an ongoing basis.

Salary requirements for sponsored workers

Pay is one of the most closely checked areas. For the Skilled Worker visa, the general threshold is £41,700 a year or the going rate for the occupation, whichever is higher. Lower salaries are allowed for some groups of applicants, as set out on the Skilled Worker visa page on GOV.UK. Employers must also comply with national minimum wage law.

A sponsor must pay the worker at least the amount stated on the certificate of sponsorship. If the salary goes down — for example, because hours are cut or the worker moves to a different role — this must be reported through the SMS within 10 working days. Pay rises generally do not need to be reported. Importantly, a reduction below the threshold that applies to the worker can call into question whether they still meet the requirements of their visa.

Salary checks go beyond the figure in the contract. An officer compares payslips, bank payments and PAYE records, and the Home Office may work with HMRC to check compliance with the minimum wage. If payroll is run by an external accountant, their figures need to match the terms of the certificates. Bringing these processes together is easier when accounting and payroll services sit with the same team that handles the immigration side.

Home Office inspections: how to prepare for a compliance visit

The Home Office carries out compliance checks both with and without prior notice. A check may take place at the business’s premises or remotely, including by video call. Officers compare the information from the licence application with the actual situation, review records, interview sponsored workers and other staff, and may take photographs of the workplace.

The best approach is to prepare as if an officer were arriving tomorrow:

  • update the list of key personnel in the SMS and make sure they understand their duties;
  • gather files for all sponsored workers in line with Appendix D;
  • check actual duties and salaries against the certificates;
  • confirm that every report in recent months was submitted on time;
  • prepare workers for questions about their role, working hours and place of work.

Right to work checks are a separate risk. They must be carried out before each worker starts, whatever the employment arrangement. Employing someone without the right to work can lead to a civil penalty of up to £60,000 for each illegal worker, according to GOV.UK, and for a sponsor it is also grounds for revoking the licence.

Licence ratings, downgrades, suspension and revocation

A new licence is granted with an A-rating, which allows the business to assign certificates of sponsorship. If the business stops meeting its sponsor duties, the Home Office may downgrade it to a B-rating. While the B-rating is in place, no new certificates can be assigned, and the business must complete a paid action plan lasting no more than 3 months. The fee must be paid within 10 working days of being told about the downgrade.

According to the GOV.UK page on licence ratings, a business can only have 2 B-ratings while its licence is valid. If problems remain after the second action plan, the licence is revoked. For serious breaches, the Home Office may suspend or revoke the licence straight away, without an interim downgrade.

There is no right of appeal against revocation, and a new application can only be made after at least 12 months. For a business that relies on overseas workers, this means not only a pause in hiring but also the need to deal with existing staff: their permission to stay is usually cut short, and they have to find a new sponsor or switch to another visa. That is why a suspension letter needs a response within days, not at the end of the deadline.

Common sponsor mistakes

Most Home Office findings stem not from deliberate breaches but from routine oversights that build up over the years. Typical situations include:

  • a change of office address or a new branch was never reported;
  • a worker was moved to a different role or city, but the SMS was not updated;
  • pay was reduced during a quiet period and not reported in time;
  • the Authorising Officer left and no replacement was appointed in the system;
  • the cost of the certificate of sponsorship or the Immigration Skills Charge was deducted from the worker’s pay, even though passing it on is prohibited;
  • worker files lack copies of job adverts and evidence of the right to work check.

Each of these mistakes is easy to fix early and hard to explain to an officer after the fact. Regularly comparing SMS data with the real staffing picture closes most of these risks before an inspection.

Want to check whether your business is ready for a Home Office inspection?

Imperial & Legal supports UK employers with sponsor licence matters, SMS reporting and hiring overseas workers. Book a consultation to review your situation.

A consultation is a convenient starting point, but compliance support itself is built step by step, from an initial audit to ongoing help.

How sponsor licence compliance support works: 5 stages

Support follows a cycle: first an assessment of the licence’s current state, then closing the gaps, and after that regular monitoring and inspection preparation.

Duration: 1–2 weeks
Initial consultation and licence health check

Initial consultation and licence health check

Duration: 1–2 weeks
At the first stage, Imperial & Legal advisers review the licence details in the SMS, the key personnel, the number of sponsored workers and the history of reports. The business provides information about its workers and their employment terms. The result is a clear picture of risk: which breaches already exist, which reporting deadlines are at risk and where corrections should begin.
Duration: 2–4 weeks
Document audit and closing compliance gaps

Document audit and closing compliance gaps

Duration: 2–4 weeks
Each sponsored worker’s file is checked against Appendix D, and SMS data is compared with the actual situation in the business. Imperial & Legal prepares a list of missing documents and helps submit any overdue reports. The client gathers the missing materials. The result of this stage is an archive that can be shown to an officer without a search for paperwork.
Duration: monthly
Ongoing SMS reporting and deadline control

Ongoing SMS reporting and deadline control

Duration: monthly
From here, the work becomes routine. The business shares staffing changes, and advisers assess whether each one needs to be reported and submit the report within the deadline. Salaries are checked against the terms of the certificates at the same time. The employer gets a predictable process in which the 10 and 20 working day deadlines no longer depend on one person’s holiday.
Duration: 1–3 weeks
Preparing the business for a Home Office visit

Preparing the business for a Home Office visit

Duration: 1–3 weeks
Before a planned visit, or as a preventive step, a mock inspection is carried out: advisers ask key personnel and workers the questions an officer may ask and check that records are easy to access. The business sets aside time for the people involved and provides access to documents. The result is a clear plan for the day of the visit and resolved findings.
Duration: ongoing
Support with new hires and business changes

Support with new hires and business changes

Duration: ongoing
When the business hires new workers, restructures, changes ownership or opens a branch, Imperial & Legal assesses the impact on the licence and prepares the required reports. If the Home Office downgrades the rating or suspends the licence, advisers help prepare a response and complete the action plan. The result is a licence that grows together with the business.

How long the first two stages take depends on the number of workers and the state of the records. From the third stage onwards, compliance support works as a permanent function of the business that does not have to be restarted each time.

Costs and timescales: government fees for sponsors

The cost of compliance support is calculated individually and depends on the number of sponsored workers and the scope of work. Government fees are paid separately and are set by the Home Office. The main amounts according to GOV.UK at the time of publication are shown below.

FeeSmall or charitable sponsorMedium or large sponsor
Sponsor licence (Worker)£611£1,682
Certificate of sponsorship (Worker)£525£525
Immigration Skills Charge — first 12 months£480£1,320
Immigration Skills Charge — each additional 6 months£240£660

The figures come from the GOV.UK pages on applying for a licence, certificates of sponsorship and the Immigration Skills Charge. Most licence applications are decided in under 8 weeks. An extra £750 buys a decision within 10 working days, but places on the priority service are limited.

When planning a budget, it is worth considering indirect costs too: staff time spent preparing for an inspection and, in the worst case, the action plan fee after a downgrade and a pause in hiring. Compared with these losses, regular compliance support usually costs less.

Practical examples: how compliance gaps affect a business

A typical scenario: a restaurant group sponsors several chefs. One of them moves to another restaurant in the same group in a neighbouring town, but nobody reports the change of work location. During an inspection, the officer cannot find the worker at the address on the certificate, and the business has to explain why the SMS data does not match reality.

Another example is an IT company whose director changed. The former director was the Authorising Officer, and after they left the role formally remained empty. When the company needed to assign a certificate to a new specialist urgently, it turned out that the key personnel had to be updated first, which takes time. In both cases, the problem could have been prevented by simple regular checks.

Similar situations come up in Imperial & Legal’s work. Below are real stories of employers and workers who needed help with a sponsor licence after inspections and changes in the business.

How to keep a sponsor licence in the long term

An indefinite licence changes how sponsorship works: compliance becomes an ongoing process rather than preparation for renewal. The main points:

Key takeaways

  • report changes to workers within 10 working days and changes to the business within 20 working days;
  • keep Appendix D records throughout sponsorship and after it ends;
  • pay at least the amount stated on the certificate and report any salary reduction;
  • check the right to work before each worker starts;
  • keep key personnel and SMS access up to date following the September 2026 changes;
  • remember that a B-rating can only be given twice, and after revocation a new application is possible only after 12 months.

This page is for general information only and does not constitute individual legal advice. Home Office requirements are updated regularly, so decisions in a specific case should take into account the current version of the guidance and the business’s circumstances.

FAQs about sponsor licence compliance support

Do employers still need to renew a UK sponsor licence?

No, for most licences renewal is no longer required. The requirement to renew a licence every four years was removed on 6 April 2024, and once granted, a licence remains valid for an indefinite period. However, this does not remove the duties: the Home Office can check a business at any time and, if it finds breaches, downgrade the rating, suspend or revoke the licence. Instead of preparing for renewal, an employer therefore needs ongoing control of reporting, records and workers’ employment terms.

Which changes must a sponsor report through the SMS?

Reports fall into two groups. For workers, the sponsor must report within 10 working days if a worker does not start work, is absent without permission for more than 10 consecutive working days, takes unpaid leave of more than 4 weeks in a year, has their salary reduced, or sees significant changes to their duties or place of work, as well as when sponsorship ends. For the business, changes of key personnel, address, name, new branches, mergers, takeovers or changes of ownership must be reported within 20 working days.

What changed in sponsor access to the SMS in September 2026?

Since 3 September 2026, multi-factor authentication has been mandatory for SMS users: logging in now requires an additional verification code. Since 9 September 2026, new Level 2 users can no longer be added, as this role is being phased out. Businesses where Level 2 users handled reporting should review who has access and appoint enough Level 1 users, so that reports continue to be submitted without interruption, even when a staff member is on leave or leaves the business.

How long must a sponsor keep records for sponsored workers?

Records are kept for as long as the worker is sponsored and then until the earlier of two dates: one year after sponsorship ends, or the date a Home Office compliance officer has examined and approved them. The list of documents is set out in Appendix D: evidence of the right to work, recruitment records, the employment contract and payslips, evidence of qualifications, contact details and absence records. They can be kept on paper or electronically, as long as they are quick to access.

Can an employer reduce the salary of a Skilled Worker visa holder?

A reduction below the amount on the certificate of sponsorship must be reported through the SMS within 10 working days. But reporting does not solve the main problem: if the new salary falls below the threshold that applies to the worker, this may affect whether their visa still meets the requirements. The general Skilled Worker threshold is £41,700 a year or the going rate for the occupation, whichever is higher, although exceptions apply to some groups. Before any reduction, it is worth assessing the consequences for the specific worker.

How does a Home Office compliance visit work, and is notice given?

Compliance checks can take place with or without prior notice. An officer may visit the office or carry out the check remotely, including by video call. During the check, officers review records, interview key personnel and sponsored workers, and compare actual duties, place of work and salary with the details on the certificates. The Home Office may also request information from other government departments, such as HMRC. The best preparation is keeping records and the SMS in order at all times, not rushing after an officer calls.

What does a downgrade of a sponsor licence to a B-rating mean?

A B-rating means the business is not meeting some of its sponsor duties. During this time, it cannot assign new certificates of sponsorship and must complete a paid action plan lasting no more than 3 months, paying for it within 10 working days of being notified. If all the steps are completed, the rating can be restored to A. A business can only have 2 B-ratings while its licence is valid, and if problems remain after the second plan, the licence is revoked.

What happens to sponsored workers if the business loses its licence?

Revocation affects not only the business but also its sponsored workers. Their permission to stay is usually cut short, and they need to find a new sponsor, switch to another visa or leave the UK within the set period. There is no right of appeal against revocation, and the business can only apply for a new licence after at least 12 months. That is why, on receiving a suspension letter, it is important to assess the situation straight away and prepare a response within the deadline.

Can the cost of a certificate of sponsorship be deducted from a worker's pay?

No, where the cost is one that sponsors are barred from passing on. The sponsor guidance requires sponsors not to try to recover sponsorship fees or associated administrative costs from a worker where this is expressly prohibited. This covers, in particular, the certificate of sponsorship fee, the Immigration Skills Charge and licence fees. Trying to deduct these amounts from pay or treating them as a debt owed by the worker is a breach of sponsor duties.

Who in the business is responsible for meeting sponsor duties?

Overall responsibility lies with the Authorising Officer, a senior person appointed in the SMS. The Key Contact handles communication with UKVI, and Level 1 users work in the system: they assign certificates and submit reports. If any of the key personnel leave, a replacement must be appointed and reported within 20 working days. External compliance support does not remove responsibility from the business, but it helps build a process in which duties are met on time regardless of staff changes.
