Hiring the right person sometimes means hiring someone who does not yet have the right to work in the UK. When that happens, a sponsor licence is usually the door you have to walk through, and for a small business it can feel like a daunting one. The application is paperwork-heavy, the duties continue for years, and the consequences of getting it wrong are serious.

This guide explains, in plain terms, when you need a sponsor licence, how the process works, what it costs, and the compliance responsibilities that come with it, so you can decide whether sponsorship is worth it for your business.

This article is general information, not legal or immigration advice. Immigration rules, fees and salary thresholds change frequently and the details depend on the specific route and individual. Always confirm the current position on GOV.UK and consider taking advice from a qualified immigration adviser before applying or making a job offer.

When does a small business actually need a sponsor licence?

You need a sponsor licence if you want to employ someone who does not already have permission to work in the UK in the role you are offering, and who needs to be sponsored under a work route such as the Skilled Worker route. You do not need a licence to employ people who already have the right to work, for example British and Irish citizens, those with settled or pre-settled status, or people with another visa that allows the work.

So the first question is not “do we want to sponsor?” but “does this candidate need sponsoring at all?” That is established by a proper right-to-work check, which every employer must do for every new hire regardless of nationality. If you are not confident your checks are watertight, start with our guide to right-to-work checks for small employers; sponsorship sits on top of those duties, it does not replace them.

The main work routes and what they require

The Skilled Worker route is the one most small businesses use. To sponsor someone under it, the job generally has to meet a required skill level and a salary threshold, and the role must be a genuine vacancy. Salary thresholds in particular have moved in recent years, so treat any figure you read second-hand with caution and check the current minimums on GOV.UK before you build a job offer around them.

There are other routes (for example for temporary work, intra-company transfers and specific sectors), each with its own rules. The principle is the same throughout: you must be a licensed sponsor, the role must qualify, and the worker must meet the route's requirements.

How to apply for a sponsor licence

The application is made online through GOV.UK, and broadly involves four things:

  1. Choosing the right type of licence (Worker, Temporary Worker, or both) and the routes you want to be able to sponsor on.
  2. Appointing key personnel: an Authorising Officer, a Key Contact and at least one Level 1 User who manages the system day to day.
  3. Submitting supporting documents that prove your business is genuine, trading and capable of meeting its duties.
  4. Paying the application fee, which is lower for small or charitable sponsors than for larger organisations.

The Home Office may visit your premises before or after granting the licence to check your systems and that the role is real. If approved, you are given an A-rating and access to assign Certificates of Sponsorship to the workers you hire.

What it costs, realistically

There is no single number, because several fees stack up. Expect to budget for the licence application fee itself, then, for each worker you sponsor, a Certificate of Sponsorship fee, the Immigration Skills Charge (which is higher for medium and large sponsors than for small ones), and often the worker's own visa fee and Immigration Health Surcharge if you agree to cover them.

Treat a sponsor licence as an ongoing investment in your hiring system, not a one-off form. The fees are the small part; the compliance is the commitment.

Because the figures change and depend on your size and the route, work out a per-hire cost from the current GOV.UK fee tables before you commit. For many SMEs the maths still works when the right candidate is genuinely hard to find domestically; it is the surprise of the cumulative cost, not any single fee, that catches people out. Growing firms that win public contracts often face exactly this skills crunch, so it is worth keeping an eye on the work coming up by searching live UK tenders alongside your hiring plans.

Your ongoing compliance duties

This is where most of the real work lives. As a licensed sponsor you take on continuing duties that the Home Office can check at any time, including:

  • Record-keeping: keeping right-to-work documents, contact details and absence records for each sponsored worker.
  • Reporting: telling the Home Office within set time limits about changes such as a worker not turning up, leaving early, a significant change in their role or salary, or your business moving address or restructuring.
  • Genuine roles and lawful pay: only sponsoring real vacancies at or above the required salary, which means your employment contracts and pay records need to be accurate and consistent.
  • Not undercutting wage rules: sponsored salaries must also respect general pay law, so cross-check against the national minimum and living wage as well as the route's threshold.

Failing these duties can lead to your licence being downgraded, suspended or revoked, which would end your ability to sponsor and can affect the workers already with you. Good HR systems are not optional once you hold a licence; they are the licence.

Common reasons applications are refused, and how to avoid them

Refusals usually come down to a handful of avoidable problems: missing or inconsistent documents, an Authorising Officer who is not appropriate, evidence that the business is not genuinely trading, HR systems that clearly could not meet the reporting duties, or a role that looks contrived to fit a candidate rather than a real need.

The fix for almost all of these is preparation. Get your statutory documents in order, make sure the named people understand their responsibilities, and be able to show a clean, honest hiring process. If the role is borderline on salary or skill, resolve that before you apply rather than hoping it slips through.

Frequently asked questions

How long does a sponsor licence take to get?

Standard processing usually takes a number of weeks, though a priority service can speed it up for an extra fee when places are available. Build the timeline into your hiring plan; you cannot assign a Certificate of Sponsorship until the licence is granted, so start early if a candidate is waiting.

Can a brand-new or very small business get a sponsor licence?

Yes. There is no minimum number of employees, and small firms benefit from lower fees. What matters is that you are a genuine, lawfully operating business with the HR systems to meet your duties. New businesses simply need to evidence that they are real and trading.

What happens if a sponsored worker leaves?

You must report it to the Home Office within the required time limit through the sponsorship management system, and stop sponsoring them. Keep clear records of the leaving date and the report. Missing these reporting deadlines is one of the most common compliance failures, so put a simple process in place from day one.
