UK Visa Sponsor Register - Licensed Employers

Every employer licensed by the UK Home Office to sponsor Worker and Temporary Worker visas, from the government's official open register: 143,211 registrations covering 127,427 distinct organisations as of 16 October 2026. The register is republished on every working day.

Each record carries the organisation name, town, county, the raw type and rating (Worker (A rating), Temporary Worker (A rating), ...), the sponsored route (Skilled Worker, Creative Worker, Charity Worker, ...), and the derived worker type and A/B rating.

Low cost

From $0.00005 per record, down to $0.00003 at Gold. Pay only for the records you receive - the whole register stays searchable, you are never billed for the scan behind it.

Search it

• Name - name="NHS" (substring, case-insensitive).
• Town or county - town="London" (43,884 registrations), county="Surrey" (2,368).
• Route - route="Skilled Worker" (123,185 of the 143,211 rows), "Creative Worker", "Charity Worker",

  "Global Business Mobility: Senior or Specialist Worker"
  .
• Rating - rating="A" or "B".
• Worker type - workerType="Worker" or "Temporary Worker".

Example inputs

Sponsors by name - the visa-verification starting point.

{ "name": "NHS", "route": "Skilled Worker", "maxResults": 25 }

One town - every licensed sponsor in London.

{ "town": "London", "maxResults": 50 }

B-rated sponsors - the register's compliance watch-list.

{ "rating": "B" }

Charity Worker route

{ "route": "Charity Worker", "rating": "A", "maxResults": 25 }

Counts by route - mode=aggregate.

{ "mode": "aggregate", "groupBy": "route" }

What changed since the previous working day

{ "mode": "changes" }

Or roll it up

mode=aggregate returns one count row per group - route, rating, workerType, typeRating or county. The default (empty) run answers the whole-register route summary from a small precomputed record.

mode=changes returns new registrations, removed registrations and rating changes (A to B or B to A) compared with the previous daily snapshot, one row per change. The diff appears once a second daily snapshot exists (the first warm has nothing to compare against).

Example output

 "county": "",
 "typeRating": "Worker (A rating)",
 "route": "Skilled Worker",

Notes on the data, from the source

• One row = one sponsor registration, not one employer. An employer that holds several routes appears once per route; 127,427 distinct organisation names produce 143,211 rows.
• No identifier. The register publishes no sponsor licence number, so name + town + county + route is the natural key. 662 rows duplicate that full key inside the published file itself.
• Daily refresh. The Home Office replaces the CSV on each working day; every record carries refreshedDate so you can see which snapshot it came from.
• Worker and Temporary Worker routes only. The separate register of licensed student sponsors is a different publication and is not included.
• Organisational data only. The register carries no personal data.
• Licence. Open Government Licence v3 - commercial reuse is expressly permitted, with attribution to the Home Office.
