You receive a letter from the Home Office. Your sponsor licence has been downgraded from A-rated to B-rated. An action plan is attached. You have a limited window to fix the problems they've identified, or your licence will be revoked entirely.
This isn't theoretical. In the year ending March 2025, over 3,100 UK businesses lost their sponsor licence — many of them after failing to recover from a B-rating. The businesses that survived did so because they understood what a B-rating means, what caused it, and exactly what steps were needed to get back to A.
Here's how to do that.
What a B-rating means
Every organisation that holds a sponsor licence is rated by the Home Office. An A-rating means you're meeting your sponsorship duties. A B-rating means the Home Office has identified specific failures in your compliance and has placed you on notice.
Under Sponsor Guidance Part 3, a B-rating triggers an action plan — a formal document setting out exactly what the Home Office expects you to fix and the deadline for doing so. The action plan is not optional. It's not advisory. It's a remediation requirement with a defined timeline, and failure to complete it leads to revocation.
While you hold a B-rating, your ability to sponsor new workers is restricted. You cannot assign new Certificates of Sponsorship (CoS) until the Home Office is satisfied that you've addressed the failures. Your existing sponsored workers are not immediately affected, but if the B-rating progresses to revocation, they lose their right to work for you.
How you get downgraded
B-ratings are triggered by failures that the Home Office identifies during compliance visits, desk-based audits, or cross-referencing with other government data. The four most common triggers, as outlined in Sponsor Guidance, are:
1. Record-keeping failures
The Home Office expects sponsors to maintain specific records for every sponsored worker: current contact details, copies of right-to-work documents, a record of the job they were hired for, and evidence that the role matches the Certificate of Sponsorship. If your records are incomplete, inconsistent, or inaccessible during a compliance visit, that's a B-rating trigger.
The most common version of this: records exist somewhere in the organisation, but they're scattered across HR inboxes, shared drives, and individual managers' filing systems. When the compliance officer asks for a specific worker's file, nobody can produce it within a reasonable timeframe. That's a failure — regardless of whether the underlying check was actually done.
2. Failure to report changes
Sponsors have a legal obligation to report specific events to the Home Office via the Sponsorship Management System (SMS), usually within 10 working days. These include:
- A sponsored worker not turning up for their first day
- A sponsored worker being absent without permission for more than 10 consecutive working days
- A significant change to the sponsored worker's role, salary, or working location
- A sponsored worker leaving the organisation
Missing these reporting deadlines — even once — can trigger a compliance investigation. Missing them repeatedly signals systemic failure.
3. Employing workers outside their visa conditions
Every Certificate of Sponsorship specifies the role, salary, and conditions under which the worker is authorised to work. If a sponsored worker is doing a different job, working at a different location, or earning a different salary than what's on their CoS — and you haven't reported the change and obtained a new CoS — that's a breach.
This often happens innocuously. A sponsored worker takes on additional responsibilities. A team restructure changes reporting lines. A temporary secondment becomes permanent. None of these are malicious, but all of them require action under the sponsorship rules.
4. Failing to cooperate with a compliance visit
When the Home Office conducts a visit — announced or unannounced — they expect cooperation. That means making records available promptly, providing access to the workplace, and making the relevant personnel available for questioning. Delay, obstruction, or disorganisation during a visit can itself trigger a downgrade, even if your underlying compliance is otherwise adequate.
What the action plan looks like
When you receive a B-rating, the accompanying action plan will specify:
- The specific failures identified — usually mapped to particular paragraphs of Sponsor Guidance
- The remedial actions required — what you need to fix, in concrete terms
- The deadline — typically between one and three months, depending on the severity of the failures
- Evidence requirements — what documentation you'll need to provide to demonstrate that the issues have been resolved
The Home Office will then conduct a follow-up review — which may include another site visit — to verify that the action plan has been completed. If it has, your licence is upgraded back to A. If it hasn't, revocation proceedings begin.
What happens if you don't fix it
The consequences of failing to recover from a B-rating are severe:
Revocation. Your licence is withdrawn. Every sponsored worker's visa is curtailed to 60 days. They must find a new sponsor or leave the UK. You lose your entire sponsored workforce in one action.
12-month cooldown. You cannot re-apply for a sponsor licence for at least 12 months after revocation. If your workforce model depends on overseas talent, you're locked out of your recruitment pipeline for a year.
Public record. The register of licensed sponsors is published by the Home Office and searchable by anyone — prospective employees, clients, regulators. Your revocation is visible.
Cascading scrutiny. In regulated sectors like health and social care, losing your sponsor licence can trigger further investigation from bodies like the CQC. It signals a compliance culture problem that extends beyond immigration.
Step-by-step recovery
If you've received a B-rating — or want to prevent one — here's the practical path.
Step 1: Audit every sponsored worker record
Go through every active sponsored worker file. For each person, confirm you hold:
- Their full name, date of birth, and current home address
- A copy of their passport and visa (or BRP)
- Their Certificate of Sponsorship reference number
- Their job title, SOC code, salary, and work location — matching the CoS
- The date their right-to-work check was last conducted
- Evidence of any changes reported to the Home Office
If anything is missing, flag it and fix it immediately. Don't wait for the action plan deadline to start — begin the day you receive the letter.
Step 2: Close your reporting gaps
Review the last 12 months for any reportable events you may have missed. Did anyone leave without being reported on SMS? Did anyone change role, location, or salary without a new CoS? Did anyone fail to show up on their start date?
If you find missed reports, submit them now. Late reporting is better than no reporting. Document the date you identified the gap and the date you remediated it — the Home Office will want to see evidence of your corrective action.
Step 3: Centralise your records
This is the structural fix that prevents recurrence. Move all sponsor compliance records into a single, centralised system where any authorised person can retrieve a complete file for any sponsored worker within minutes. Not hours. Not "I'll need to check with the site manager." Minutes.
Your system needs to track:
- Visa and CoS expiry dates, with automated alerts before they lapse
- Reporting deadlines, with clear ownership of who submits what
- A complete audit trail of every check, update, and report — timestamped and attributable
Spreadsheets won't survive a follow-up visit. If the compliance officer found your records inadequate the first time, they'll expect a material improvement at the follow-up.
Step 4: Assign clear ownership
Compliance failures are almost always shared failures — multiple people assumed someone else was handling it. Designate a specific individual (your Authorising Officer, Key Contact, or Level 1 User) as the owner of sponsor compliance. Give them the authority, the time, and the tools to do the job properly.
Step 5: Prepare for the re-inspection
The Home Office will come back. Treat the follow-up visit like an exam you know the date of. Run a mock audit: can you produce every record they'll ask for? Can you demonstrate that every reporting obligation has been met? Can you show the system changes you've made to prevent the same failures recurring?
If you can do all of that confidently, you'll get back to A. If you can't, you need more time on Steps 1–4.
Prevention is cheaper than recovery
The businesses that avoid B-ratings aren't the ones with bigger HR teams or more expensive lawyers. They're the ones with systems that make compliance automatic rather than manual. Where visa expiry dates trigger alerts rather than relying on someone's memory. Where compliance records are complete and accessible rather than scattered across inboxes. Where reporting obligations are tracked by a system rather than an individual.
The cost of building those systems is a fraction of the cost of fighting a B-rating — let alone a revocation. And with the Home Office showing no signs of reducing its compliance activity, the window for reactive approaches is closing.
Certifyd's Right to Work Portal gives sponsors a centralised compliance system with automated expiry tracking, digital document collection, and audit-ready reporting. When the Home Office asks for records, you produce them in seconds — not hours.
