How Many UK Employers Can Sponsor a Visa? We Counted the Register

The Home Office publishes the full list of organisations licensed to sponsor workers for a UK visa, and almost nobody reads it. It is a 10.9 MB spreadsheet with 143,008 rows and no summary. We counted it. Here is what the UK’s sponsorship system actually looks like from the inside — and why four of the numbers below should change how you use the register.

Everything in this article comes from the register as published on 10 November 2026. You can search the same data yourself in our licensed sponsor directory, which is rebuilt from the GOV.UK file every week.

The headline numbers

The raw file contains 143,008 rows, but a single employer appears once for every visa route on its licence. Collapse those and you get the number that matters.

So: roughly 127,600 licensed sponsor records. That number only means something next to the size of the UK economy, so here is the comparison nobody seems to publish. Government business population estimates put the UK at 5,586,835 private sector businesses at the start of 2026, of which 1,471,660 actually employ anyone. Only an employer can sponsor a worker, so the second figure is the right denominator.

That puts licensed sponsors at roughly 8.7% of UK employing businesses — about one in twelve. Measured against all businesses, including the 4.1 million with no employees, the share falls to 2.3%, or one in forty-four.

One in twelve employers is higher than most people assume, and it is the more honest number. It is also an upper bound rather than a precise ratio: the register records an organisation once per location, so a multi-site employer can appear several times, and a few licence holders are not conventional businesses at all — universities, NHS trusts, councils, churches and charities are all in there.

Almost all of it is one route

The register covers eighteen different route labels, which gives an impression of breadth that the counts do not support.

Shares add to more than 100% because a sponsor can hold several routes.

Skilled Worker accounts for 95.8% of sponsor records. The second-placed route, Global Business Mobility: Senior or Specialist Worker, covers staff an employer moves in from its own overseas offices — it is not a route an outside applicant can use. Everything below it is a niche: religion, sport, the creative industries, a handful of named exchange schemes.

The practical consequence is that if you are applying to a UK employer from abroad and the register shows a licence that does not include Skilled Worker, the licence is almost certainly irrelevant to you. That is the single most common misreading of this dataset.

The Seasonal Worker count deserves a note of its own: six sponsors, for a scheme that brings tens of thousands of workers into UK horticulture every year. Those six are the scheme operators, not the farms. The register records the licence holder, which is not always the place the work happens.

The rating column is nearly useless as a filter

Every licence carries a rating. An A rating means the licence is in good standing; a B rating means the Home Office has imposed an action plan and the sponsor’s ability to issue new Certificates of Sponsorship is restricted while it runs.

In the whole register, 112 sponsors are B-rated. That is 0.09% — fewer than one in a thousand. A further 99 records carry no rating value at all, mostly provisional licences.

Advice articles routinely tell applicants to “check the sponsor’s rating”. The check is worth thirty seconds, but understand what it tells you: almost every employer passes, so an A rating is not a signal of quality, scale or willingness to sponsor. It is the default state.

Where the sponsors are

Geography is where the register gets genuinely interesting, because the concentration is more extreme than the headline totals suggest.

London alone holds 28.7% of every sponsor record in the country. The ten towns above hold 39.9% between them. Extend the list to fifty towns and you have 56.9%; to a hundred and you have 65.8%. Two-thirds of the UK’s sponsorship capacity sits in a hundred places.

The appearance of Ilford, Harrow, Hounslow, Southall, Wembley and Romford in the upper reaches of the list is worth noticing. These are London boroughs and suburbs recorded under their own names rather than as “London”, which means the true London-area share is higher than 28.7% — the register’s geography is recorded as the sponsor typed it, not cleaned to a standard place list.

More than half the towns on the register have one employer

This is the finding that surprised us most.

The median town on the register has exactly one licensed sponsor. Of 5,819 places, 3,205 have a single employer that can sponsor anybody, and 4,836 — 83% — have fewer than ten. Nine towns have a thousand or more.

If you need sponsorship and you are tied to a particular town, that is the number that should shape your expectations. In most of the UK, sponsored work means one employer, in one sector, or it means moving.

The register still prints route labels the rules have retired

Buried in the counts are four labels that should not be there.

Tier 2 General appears against five licences. Tier 2 (General) was replaced by Skilled Worker in December 2020. Intra Company Transfers (ICT) and Intra-company Routes appear against one licence each; those routes were folded into Global Business Mobility in April 2022. And Tier 2 Ministers of Religion, with 1,957 licences, uses a naming convention the immigration rules dropped years ago — the route is now simply Minister of Religion.

None of this makes the register wrong about who holds a licence. But it does tell you something about how the file is maintained: it is a live administrative record with historical sediment in it, not a curated dataset. Treat the route labels as a guide and verify anything that matters against current Home Office guidance.

What the file does not contain

Worth stating plainly, because a lot of sites imply otherwise. The published register has five columns: organisation name, town or city, county, licence type and rating, and route. That is all.

There is no address, no postcode, no licence number, no website, no email, no phone number, no industry or sector classification, and no licence start or expiry date. County is filled in on only 33.6% of rows. There is no indication of whether a sponsor has ever issued a Certificate of Sponsorship, how many, or whether it is recruiting now.

Any site offering you a sponsor’s contact details, hiring volumes or “sponsorship likelihood” alongside this data has added that from somewhere else, and you should ask where.

How to use it

The register is a disqualifier, not a lead list. Find roles you genuinely want, then check whether the employer holds a licence and whether that licence covers Skilled Worker. No licence means no sponsored job, however the interview goes. A licence means the door is not locked — nothing more.

Search names short. Employers appear under the name on the licence, which is often a legal or holding-company name rather than the brand you know, so “Oakwood” will find more than “Oakwood Academy Trust Limited”.

And check the town field twice. It is the location on the licence, usually a head office. A trust headquartered in Leeds may be hiring in Hull.

Method and source

Figures are from the Home Office Register of licensed sponsors (workers), file published 10 November 2026, containing 143,008 data rows. We counted distinct sponsors by normalising organisation name and town to lower case, removing punctuation and accents, and collapsing whitespace, then treating each name-and-town pair as one sponsor; this merges obvious spelling variants of the same employer in the same place and separates same-named organisations in different places. Route, rating and licence-type shares are counted on the same basis, so a sponsor with three routes contributes once to each.

Business population figures are from the Department for Business and Trade’s Business population estimates for the UK and regions 2026: 5,586,835 private sector businesses at the start of 2026, of which 1,471,660 are employers.

Our figure of 127,640 distinct sponsors is therefore lower than the 143,008 rows and slightly lower than a naive count of unique name strings. We publish the method so you can reproduce it. The same data, searchable, is in our licensed sponsor directory, refreshed weekly.
