Welcome to Job Search Tools UK

Quick answer

A UK job search produces thousands of pages and very little signal. The tools worth your time do one of three things: check the employer against the UK sponsor register, read the job ad for sponsorship clues, or track what you have applied for. The most private sponsor checkers run on your own machine, because that is what makes them free and private.

What this site covers

Job Search Tools UK reviews and compares the tools used in a UK job search, especially by international candidates who need to know whether an employer can sponsor a visa.

How we review

Every review answers the same questions: what does it do, what does it cost, what data does it see, and what can it not tell you? We check every tool's claims against the GOV.UK register of licensed sponsors and against its own store listing, and we name the source for every figure. If a tool makes a claim we cannot verify, we say so.

Who runs this site

This site is published by the team behind Sponsio, which makes tools in this category — so some tools we review compete with ours. We do not review our own products, and if we ever mention one, we label it as ours. We do not accept payment from any third party for reviews. Each review states the limits of the tool it covers, and every figure is checked against the tool's own listing or the GOV.UK register. If a tool makes a claim we cannot verify, we say so.

The tools that matter

Start with the guides below. The first one compares the extensions worth installing, the second walks through the sponsorship-checking options, and the third shows the free checks you can do with no tool at all.
