Sponsor register data & methodology
Where these figures come from, and what they can't tell you
The Home Office register is the official source. We add the date of each change and company details from Companies House. Where the data can't answer a question, we say so.
The register
The sponsor list comes from the Home Office Register of Licensed Sponsors (Workers), published on GOV.UK as a CSV file under the Open Government Licence v3. It lists every organisation that can currently sponsor workers, with its town, licence type, rating and the visa routes it covers.
The Home Office updates the register on most working days. We check GOV.UK every day, compare the new file with the last one, and record each addition and removal with the date we saw it. GOV.UK only shows the current list, so once an employer drops off, the official file no longer shows it was ever there.
We don't change the register data. Names are shown in title case to make them easier to read.
Active, removed and ceased
A sponsor is Active when it is on the current register. When it leaves, its page stays online and its status changes to Removed or Ceased.
Removed means it has left the register but the company is still live at Companies House, or we don't know its company status. Ceased means it has left the register and Companies House shows the company as dissolved, in liquidation, in administration or otherwise closed.
We only mark a sponsor as Ceased when Companies House clearly shows the company has closed. GOV.UK gives no reason when an employer leaves the register, so a licence that was revoked, surrendered, replaced after a change of owner or allowed to lapse all look the same. We can tell you that a licence left the register and when, but not why.
Companies House checks
Where we can match a sponsor to a Companies House record, we track changes filed since the licence appeared: new owners or controllers, share transfers, directors joining and leaving, registered office moves, name changes, and whether the company is still trading.
Some of these changes matter to the Home Office. A takeover or the sale of a controlling stake can need a new sponsor licence. Most other changes must be reported through the Sponsorship Management System within 20 working days. Each change on a sponsor's page shows what must be reported and by when.
We re-check each sponsor about every three months and show the date of the last check.
Signals, not scores
We don't rate sponsors or give them a risk score. Each sponsor page lists the Companies House changes filed since the sponsor joined the register, and what the sponsor would need to do if a change affects the licence. For example: “Director change recorded on 3 Nov 2025. If this person was your Authorising Officer, Key Contact or Level 1 user, the change must be reported in the SMS (the Home Office sponsor system) within 20 working days.”
Companies House can't show who holds these licence roles or whether a change was reported to the Home Office. A change listed here is a reason to check your own records, not proof that anything was missed.
If something on a sponsor’s page is wrong, use “Request a correction” on that page. The Borderless team reviews every request.
Job listings
Job adverts are collected daily from Reed, Adzuna, Jooble and Careerjet and matched to sponsors by employer name. Name matching isn't exact, and an advert on a sponsor's page doesn't mean that job offers visa sponsorship.
Closed adverts are kept and marked expired, so a sponsor's hiring history stays visible.
What this site is not
This is not the official register, and it is not legal advice. It is a searchable copy run by Borderless Immigration, an OISC-regulated UK immigration provider, with change dates and Companies House details added.
For anything important, such as a visa application, a hiring decision or a compliance response, check GOV.UK and get advice.
