Can my employer make me repay training costs if I leave my job?

The short version

You can sign a clawback clause and still not owe the money, if the clause itself will not hold up in court. Employers can lawfully ask for some training costs back if you leave soon after receiving them. But the clause has to be fair. Courts strike these down regularly, most recently in July 2026, when the Court of Appeal cancelled an £8,108 training debt because the clause behind it went further than the law allows.

Why training clawback clauses exist

Employers who invest in training, mentoring, or qualifications sometimes want that investment protected if you leave shortly afterwards. A repayment clause, sometimes called a clawback or a training investment agreement, is meant to recover some of that cost.

That is a legitimate aim in principle. The problem is how far the clause goes, and what it actually does to your pay once it is applied.

The two tests a clawback clause has to pass

Courts ask two separate questions when deciding whether a repayment clause holds up.

Is the amount genuinely tied to the cost, or does it look like a punishment? A repayment figure that reflects real, documented training costs is more defensible than one that is inflated or arbitrary. If the sum you are asked to pay is designed to hurt rather than to compensate, it can be struck down as an unlawful penalty rather than a fair estimate of loss.

Does the clause apply no matter why you left, and what does it actually do to your pay? A clause that catches you whether you resigned, were dismissed, or left for reasons that had nothing to do with a new job is not targeted at protecting a legitimate business interest. It is just punishing departure. Courts also look at what the clause does to your actual earnings. If repaying it leaves you working for close to nothing in your early months, that is a strong sign the clause goes further than it needs to.

The case that changed the picture: Geeks Ltd v Watts

In July 2026, the Court of Appeal struck down a training cost clawbackA clause that requires you to repay some or all of your training costs if you leave your job within a certain time. It is only enforceable if it is fair and reasonable. used by an IT company against a trainee QA engineer. He had signed a separate “training investment” contract fixing an £8,108 debt, including his mentor’s time costed well above what the mentor was actually paid.

He left after eight months for a better-paid job elsewhere. The company sued for the outstanding balance, two years after he had gone.

The Court of Appeal sided with him, for two reasons: the clause applied whatever the reason for leaving, and its practical effect was to reduce his early pay to close to nothing once repayments were factored in. Read the full story in our case study, A training cost clawback that applies no matter why you left probably isn’t enforceable.

Watts is not an isolated result. Twenty-six years earlier, the Employment Appeal Tribunal struck down a different kind of leaving-related deduction, a notice buyout clause for a driver, on similar grounds: if a clause is not a genuine estimate of your employer’s loss, and instead looks designed to punish you for leaving, it is an unlawful penalty. See our case study on A leaving-notice deduction that ignores your employer’s real loss can be an unlawful penalty for the full detail. The same underlying idea, that a clause has to compensate rather than punish, runs through both cases.

Red flags to check in your own contract

If you have signed, or are being asked to sign, a training repayment clause, look for:

No breakdown of costs. You have the right to see exactly what that figure is made up of. A clause with no supporting calculation, or one padded with costs unrelated to your actual training, is weaker than it looks.

Applies on dismissal, not just resignation. If you would owe the money even if your employer ended your employment, that is one of the clearest signs a clause will not survive a challenge.

All-or-nothing repayment. A clause that owes the full amount right up to a cliff-edge date, rather than reducing gradually the longer you stay, is harder to defend than one that tapers.

Deducted straight from your final pay. If the sum is simply taken out of your last payslip rather than pursued as a separate debt, that raises a further issue under the rules on deductions from wages, on top of whatever restraint of tradeA rule that stops a contract clause from unfairly limiting what you can do after you leave a job, unless it genuinely protects your employer's real business interests and goes no further than necessar... argument applies.

What to do if you are being asked to repay

Ask for the breakdown behind the figure first. You are entitled to see what you are actually being asked to pay for.

Check the circumstances of your departure. Whether you resigned, were dismissed, or were made redundant can change whether the clause should apply to you at all.

Check whether any money has already been deducted from your pay. That can be a separate unlawful deduction of wages issue, on top of any argument about the clawback clause itself.

Get advice before you repay anything or sign a settlement. A clawback clause in your contract is not automatically the last word. Courts have shown they will look closely at whether it goes further than the law allows.
