The UK skilled worker visa cost for a small tech business is the reason most of us never get past the first conversation about hiring from overseas. I have had brilliant developers reach out over the years, people I would have hired on the spot if they were already living in the UK, and every single time the sponsorship maths has talked me out of it. Not because I did not want to hire them. Because the numbers simply did not work for a business my size.
That is not me being precious about spending money on good people. I would rather pay someone well than save a few thousand pounds on process. The problem is the process itself was built for a different kind of employer, and small software businesses are paying a tax on ambition that big tech barely notices.
Getting a Sponsor Licence Before You Have Hired Anyone
Before you can sponsor a single person, you need a sponsor licence, and that is its own project. You are filling in forms about your HR processes, proving you can track someone's right to work, and in some cases sitting through a compliance visit from the Home Office before you have even advertised the role. The licence fee itself for a small sponsor is a few hundred pounds, which sounds fine in isolation. It is the time and the administrative burden around it that actually costs a small business, because none of us have a dedicated HR team to absorb that work quietly in the background.
Big employers have a compliance department that does this without anyone noticing. A five person software company does not. The founder, or whoever is closest to admin that week, has to become an expert in sponsor duties they will use for exactly one hire.
What Sponsoring One Developer Actually Costs
The Certificate of Sponsorship and the Skills Charge
Once you have the licence, every person you sponsor needs a certificate of sponsorship, which is a few hundred pounds on its own. Then comes the Immigration Skills Charge, which is where the number stops looking like a rounding error. For a small sponsor it runs into four figures for every year of the visa, paid up front for the whole length of the sponsorship. Sponsor someone for three years and you are committing that amount before they have started a single day of work.
The Visa Fee and the Health Surcharge
Then there is the visa application fee itself, and the Immigration Health Surcharge on top, which the employee usually needs reimbursing for if you want the offer to be genuinely competitive. Add it all up, licence, certificate, skills charge, visa fee, health surcharge, and a small business can be several thousand pounds into a single hire before that person has written a line of code or closed a single support ticket.
Compare that with the on costs of hiring someone already in the UK, the kind of number I broke down properly in what the employer National Insurance rise actually costs a small tech business, and sponsorship is not a marginal extra. It is a genuinely different order of financial commitment for exactly the businesses least able to absorb it.
The Salary Threshold Prices Out the Businesses That Need the Talent Most
On top of the fees, sponsored roles have to clear a minimum salary threshold that sits well above what a lot of bootstrapped software businesses can offer a first or second overseas hire. That threshold does not flex for a founder who is watching runway carefully or a small SaaS business still finding its feet. It is one number, applied the same way to a three person startup and a company with a finance team and a boardroom.
A well funded scale up can absorb that salary level without blinking. A bootstrapped founder trying to bring in one exceptional developer from outside the UK is often priced out before the sponsorship fees even come into it, which makes the whole route feel designed for businesses that were never really struggling to hire in the first place.
Why This Matters When We Already Cannot Find Enough Developers
I have written before about why the UK is not producing enough developers domestically, and the visa sponsorship costs make that shortage worse rather than better. The whole point of a skilled worker route should be to let businesses plug a genuine gap when the local talent pool cannot fill it. Instead it is structured in a way that only the businesses who could probably have found someone anyway, the ones with budget to spare, can actually use it.
Small tech businesses are exactly where a lot of the UK's genuine innovation happens, and we are the ones locked out of a global talent pool by a cost structure that assumes everyone hiring has a corporate balance sheet behind them.
What I Would Actually Tell a Founder Considering This Route
Work out the full landed cost before you fall in love with a candidate, licence, certificate, skills charge, visa fee, health surcharge, and the salary uplift needed to clear the threshold. Treat that as one number, not five separate small ones, because that is how it hits your bank account.
Look hard at whether a genuinely remote arrangement gets you most of the benefit without the sponsorship bill at all. It is not always possible depending on the role, but for a lot of software work it is worth ruling out properly before you commit to the sponsorship route.
And go in with your eyes open about the ongoing duties. Sponsorship is not a one off cost, it is an ongoing compliance relationship with the Home Office that continues for as long as that person works for you. Budget the time for that as honestly as you budget the fees.
My Honest Take
I am not against a proper points based immigration system. I think the UK should absolutely be competing for the best developers in the world. What I object to is a cost structure that makes that competition impossible for exactly the businesses doing the most interesting and riskiest work in UK tech. Every founder I know who has looked at sponsoring a developer has done the same sums I have and reached the same conclusion, which is a genuine loss for the people who never got the job and for the businesses that never got to hire them.
If you are weighing up how to structure your next hire, sponsored, remote, contractor, or something else entirely, that is exactly the kind of decision I help founders work through as part of consulting. It is the same get the real numbers on the table before you commit thinking that runs through The 28 Day Startup, because the headline salary or the headline fee is never the whole story.
