About KnowYourSponsor

KnowYourSponsor is run by one person. This page says who, why it exists, and what it will never do, so you can judge whether to trust anything else on the site.

Who built it

My name is Roshan Yadav. I built KnowYourSponsor because the information was public but unusable. The Home Office does publish the full list of employers licensed to sponsor a work visa. It publishes it as a multi-megabyte spreadsheet with no search, no industries, and no way to see what changed since last week.

If you need sponsorship, that list decides which jobs are worth applying for. About 127,000 employers hold a licence, out of roughly five million in the country. Every application sent to the other 98% is wasted effort, and most people find that out far too late.

You can reach me at hello@knowyoursponsor.co.uk. I read everything, and if the site has something wrong I would rather hear it from you than not.

What it is, and what it is not

It is a search tool over a public register. That is all it is.

It is not immigration advice, and I am not qualified to give any. UK immigration advice is regulated for good reason. Nothing here assesses your case, tells you whether you qualify, or ranks your chances. If you need advice, use an adviser registered with the Immigration Advice Authority or a solicitor regulated by the SRA.

It is also not the official register. It is a daily copy of one. Before you act on anything, check the official list on GOV.UK. If the two ever disagree, GOV.UK is right and I want to know about it.

Things this site will not do

• Charge job seekers to search. The data is public. Put a paywall on it and the tool stops helping the people it is for.
• Sell or rent your email address. Not to recruiters, not to advisers, not to anyone. See the privacy notice.
• Let anyone pay to change the search results. If paid placement ever appears it will be labelled and kept out of the rankings. An employer cannot pay to be listed, delisted, or to have a Companies House warning removed.
• Pretend a guess is a fact. The industry tags and the Companies House matching are both inferred, and both are labelled as inferred wherever they appear. How they work is on the methodology page.

How it is paid for

At the moment, it is not. It runs on free static hosting and a scheduled job, and costs close to nothing.

The intention is to fund it by selling the change history to recruiters, immigration advisers and relocation firms, who want to know which employers gained or lost a licence. Those are businesses with budgets. Job seekers are not, and the search stays free regardless of whether that works.

I would rather say that plainly than pretend there is no commercial intent. A free tool with a hidden business model is worse than a paid one with an obvious one.

Corrections

If an employer is listed wrongly, if a warning is attached to the wrong company, or if anything reads as more certain than it should, tell me and I will fix it. Wrong data here costs somebody a real job application, so corrections come before features.
