How to Check If a UK Employer Can Sponsor Your Visa (Step-by-Step Guide)

One of the most common mistakes African professionals make when applying for UK visa-sponsored jobs is spending weeks — sometimes months — applying to employers who have no legal right to sponsor them. Checking the UK Register of Licensed Sponsors takes about five minutes. Skipping it can cost you your entire job search.

As of April 2026, there are over 139,900 companies on the UK Home Office’s official sponsor register — up from 125,880 in January 2025. That is a significant number. But it also means there are tens of thousands of UK employers who are not on the list, and cannot legally sponsor your visa regardless of how much they want to hire you.

This guide walks you through exactly how to check the register, what each column means, what an A-rating and B-rating tell you, and the specific red flags that signal a fraudulent job offer.

What Is the UK Register of Licensed Sponsors?

The Register of Licensed Sponsors is a live list maintained by the UK Home Office. It records every organisation that has been approved to employ non-UK workers under the Skilled Worker visa, Health and Care Worker visa, and other sponsored work routes.

To get onto this register, an employer must apply to the Home Office, pass a series of compliance checks, and demonstrate that they have proper HR systems and processes in place to manage sponsored workers. Once approved, they are issued a sponsor licence and appear on the public register with a licence rating — either A or B.

The register is updated regularly — usually every two weeks. This means a company that was on the list last month may have been removed, downgraded, or suspended since then. Always check the most recent version before acting on any job offer.

Step-by-Step: How to Check the Register

1. Go to the official GOV.UK page.
   Open your browser and go to: gov.uk/government/publications/register-of-licensed-sponsors-workers
   Do not use any third-party website, WhatsApp list, or downloaded copy from a blog. The only authoritative source is the live GOV.UK page. Third-party lists go out of date immediately.
2. Download the CSV file.
   On the GOV.UK page, you will see a link to download the register as a CSV (spreadsheet) file. Click it to download. The file name will include the date it was last updated — check this date before using it.
3. Open it in Microsoft Excel or Google Sheets.
   The file opens as a spreadsheet with thousands of rows — one per licensed employer. Do not be overwhelmed. You will use the search function to find what you need. In Excel: press Ctrl + F. In Google Sheets: press Ctrl + F. Type the employer’s name exactly as it appears on their job advertisement or company website.
4. Check the four key columns.
   Once you find the employer, look at these four columns carefully before doing anything else:
   
   Organisation Name — Confirm it matches the company you are considering exactly. Sometimes trading names differ from legal company names.
   Town/City — Confirms where the licence is registered. A London-registered sponsor can hire you to work in Manchester — this is normal.
   Organisation Type — Shows whether it is a private company, NHS trust, charity, etc.
   Route — This is critical. See the next section for what it means.
   Rating — A or B. See explanation below.
5. Verify the Route column matches the visa you need.
   The Route column tells you which specific visa type the employer is licensed to sponsor. An employer licensed for “Temporary Worker” cannot sponsor a Skilled Worker visa. Make sure the route matches what you are applying for.
6. Check the Rating column.
   A-rated means fully compliant. B-rated means under monitoring — they can still employ existing sponsored workers but cannot assign new Certificates of Sponsorship to new applicants. If the company is B-rated, your application cannot proceed until they regain their A rating.

Understanding the Route Column

This column is the one most applicants overlook — and it is one of the most important. Here is what each route means:

A-Rating vs B-Rating: What It Actually Means

B-rated sponsors can still extend the permission of workers already sponsored by them. But they cannot take on any new sponsored workers until the Home Office upgrades them back to A. Ratings can change without warning — an employer who was A-rated last month may be B-rated today. This is another reason to check the live register, not a saved copy.

What If the Employer Is Not on the List?

If you search for an employer by name and they do not appear anywhere in the register, there are four possible explanations:

• They genuinely have no sponsor licence. They cannot legally sponsor your visa. Any job offer claiming to include visa sponsorship is either mistaken or fraudulent.
• The name on the register differs from their trading name. Some companies operate under a trading name that differs from their registered legal name. Try searching for a shortened version of the name, or ask the employer for their exact legal company name as it appears on their Home Office documents.
• Their licence was recently revoked or suspended. The register removes companies whose licences are cancelled. A company that was listed six months ago may have had their licence withdrawn since.
• They are in the process of applying for a licence. Some employers advertise roles with visa sponsorship before their licence application is approved. This is legal to advertise but they cannot actually issue a CoS until approval comes through — which typically takes 8 weeks or more.

Red Flags That Signal a Fraudulent Visa Sponsorship Offer

Unfortunately, visa sponsorship scams targeting Nigerian and Ghanaian professionals are widespread. The people running these scams know that the desperation to work abroad is real, and they exploit it. These are the specific warning signs to watch for:

• They ask you to pay for a Certificate of Sponsorship. A CoS is assigned by the employer through the Home Office Sponsor Management System. It costs the employer £239 per worker. It does not cost you anything. Any offer that asks you to pay for a CoS is fraudulent — no exceptions.
• They are not on the GOV.UK register, but claim they can still sponsor you. There is no workaround. There is no “pending approval” that allows them to issue a CoS. If they are not on the register, they cannot sponsor you.
• The job was advertised on WhatsApp, Telegram, or an informal social media group. Legitimate UK employers do not recruit through WhatsApp messages. They use their official careers page, LinkedIn, Indeed UK, NHS Jobs, or established recruitment agencies.
• They ask for money upfront — for “processing fees”, “document fees”, “agency fees”, or “travel arrangements”. UK immigration law explicitly prohibits employers from charging workers recruitment fees. Any request for money as part of a job offer is illegal under the Modern Slavery Act.
• The offer arrives unsolicited — you never applied. Genuine employers do not cold-contact random individuals on social media offering them UK-sponsored jobs. If someone contacts you out of nowhere with a job offer, it is almost certainly a scam.
• The salary offered is below £41,700 but they claim it qualifies for a Skilled Worker visa. The minimum is £41,700 for most roles in 2026. Some exceptions exist — but they are specific and documented on GOV.UK. An offer significantly below this threshold claiming full visa sponsorship should be verified carefully.
• They pressure you to decide quickly. Scammers create urgency. Legitimate employers allow reasonable time for candidates to consider offers, seek advice, and verify documents.

How to Search Effectively When the Name Doesn’t Match

Large organisations sometimes have their licence registered under a parent company name, a subsidiary, or a formal legal entity that differs from their public brand. Here are practical tips for finding them:

• Search for the first word of the company name only — for example, search “Barclays” rather than “Barclays Bank UK PLC”
• Try removing “Ltd”, “Limited”, “PLC”, “Group”, or “UK” from the search — the register may list the name without these
• For NHS employers, search for the trust name — e.g. “King’s College Hospital NHS Foundation Trust” rather than “Kings College Hospital”
• Ask the recruiter or HR contact for the exact legal name as registered with the Home Office — a legitimate employer will provide this without hesitation
• Use the Filter function in Excel (Data → Filter) to filter the “Town/City” column to a specific city first, then search within those results — this narrows the list significantly for large cities like London or Manchester

Checking More Than Once: Why Timing Matters

The register is not a static document. It changes. The Home Office updates it regularly — sometimes weekly. Here is why this matters in practice:

If you check the register in January and confirm an employer is A-rated, then apply for jobs and receive an offer in March — check again in March before accepting. A company’s rating can change between your initial check and the point where you actually need them to issue a Certificate of Sponsorship.

The correct sequence is to check the register at three specific points:

• Before applying — to confirm the employer can legally sponsor you and avoid wasting time on applications to unlicensed companies
• Before accepting a job offer — to confirm their rating is still A and they are still on the register
• Before your employer assigns the CoS — your employer’s HR team should do this, but a personal check protects you from any miscommunication

What to Do If You Suspect a Scam

If you have already paid money to someone claiming to offer UK visa sponsorship and you now suspect it was fraudulent, these are your options:

• Report to the UK Home Office immigration fraud line: gov.uk/report-immigration-crime
• Report to Action Fraud (UK’s national fraud reporting centre): actionfraud.police.uk
• Report to the Nigerian Economic and Financial Crimes Commission (EFCC) if the scammer is operating from Nigeria: efcc.gov.ng
• Do not send any further money, even if they threaten that your “application will be cancelled” without additional payment — this is a continuation of the scam
• Warn others in your professional network — sharing your experience protects other people from the same fraud

Final Word

The UK Register of Licensed Sponsors is one of the most underused tools available to African professionals applying for UK jobs. It is free. It is official. It is updated regularly. And it tells you everything you need to know about whether an employer can legally sponsor your visa — in about five minutes.

The professionals who use it consistently are the ones who avoid wasted applications, avoided fraudulent agents, and eventually secure legitimate offers from employers who can actually deliver on their promises.

Use it every time. Without exception.
