My job offer says I must repay training costs if I leave. What should I check?

The offer includes a qualification you want. A separate training agreement says you must reimburse the employer if you leave within two years. You need to know what that could cost before treating the training as a straightforward benefit.

This guide covers ordinary employment training agreements in England, Scotland and Wales, not Northern Ireland. Apprenticeship funding, professional qualification schemes and other specialist arrangements need their own checks. Do not apply the fictional repayment schedule below to apprenticeship funding or assume that all employer spending can be passed to you.

Find the amount before evaluating the percentage

“100% of training costs” is not a useful maximum unless you know which costs are included. Ask for the course name, provider, fee and a breakdown of any exams, resits, travel, accommodation, salary or internal training time being counted.

Find out whether the amount is fixed, capped or based on evidenced expenditure. If a course is cancelled or the provider refunds part of the fee, ask whether that reduces the balance. Also check whether each future course could start a separate obligation and whether you must approve it before enrolment.

Record the information in one place:

If the employer cannot state the cost yet, ask how you will receive and approve the final amount. Avoid judging the exposure from the headline course price while another clause adds unspecified expenses.

Calculate the exit dates that matter to you

The following is an invented example for reading a clause, not a recommended or legally validated repayment scheme.

Suppose an agreement covers a fixed £2,400 course cost. The course finishes on 30 September 2026. The agreement expressly uses the last day of employment and states:

Under that wording, giving notice in March with a last day in April falls into the second band. If a real agreement instead uses the date notice is given, the result could change. An extra course or delayed completion could also create a different clock.

Write out two or three realistic departure dates and ask the employer to confirm the corresponding figures. If the wording says “within six months,” clarify the boundary rather than guessing which band applies on the anniversary date.

Ask what happens when leaving is not your choice

Read the trigger more closely than “if you leave.” Does it apply only to voluntary resignation? Does it distinguish misconduct dismissal, capability dismissal, redundancy or an employer ending probation?

Ask about situations that could affect you: the role being withdrawn, required training not being provided, failing an exam, or the employer cancelling the course. These are questions about the proposed terms, not a statement that every exception is automatically required by law.

You can ask for a narrower trigger, an evidenced cost cap or a reduction over time. The employer may accept, reject or offer different wording. A clear answer lets you evaluate the offer and compare it with your likely time in the role.

Separate repayment from a deduction out of pay

According to Acas guidance on training deductions, an employer may be able to deduct training costs from final wages where this was agreed in the contract or in writing beforehand. Acas says the written agreement must precede the course.

Acas also explains that deductions for mandatory training must not bring pay below the National Minimum Wage. Its guidance allows a deduction for voluntary training to take pay below that level only where the worker agreed in writing and chose to leave or was dismissed because of their conduct. These conditions do not establish that every repayment amount is enforceable.

Check Acas's separate mandatory-training guidance if the employer requires the course. Sources checked 15 September 2026.

The practical distinction is important: “you owe a balance” and “we may take that balance from this payslip” need their own basis. If money has already been deducted, keep the agreement, course details, notice correspondence and payslip, and promptly ask Acas about the actual circumstances and any relevant deadlines.

Ask for a worked answer before signing

Adapt this fictional email:

I'm pleased the offer includes [course]. Before signing the training agreement, could you confirm the maximum repayable amount and what it includes?

Please also confirm when the repayment period starts, whether the notice date or last day of employment determines the balance, and what happens if the role ends through redundancy or the company ending probation.

To check my understanding, if the course finishes on [date] and my last day is [date], what would the repayment be? Please include the agreed clarification in the training terms and explain any proposed deduction from final pay.

Keep the final version with your offer and employment contract. For the wider decision, use the job-contract checklist; if the employer revises the clause, check the replacement wording against the questions you asked.
