Repaying NHS Maternity Pay If You Don't Return to Work

Few parts of the NHS maternity scheme cause as much worry, or as many forum threads, as the repayment rule. It is short, it is easy to misread, and the Handbook leaves some practical questions open. This guide sets out exactly what the Handbook says, separates what is repayable from what you keep, shows a worked example from the same figures our maternity pay calculator uses, and covers what to do if your plans have changed. It is general information, not legal or HR advice, and your trust's maternity policy is what your employer will actually apply.

What paragraph 15.83 actually says

The rule sits under the heading "Failure to return to work" in Section 15 (Leave and pay for new parents) of the Handbook. Stripped back, it says four things:

• • The trigger: an employee who has notified their employer of their intention to return to work for the same or a different NHS employer, in accordance with para 15.15, 15.16 or 15.18, and then fails to do so.
• • The deadline: for maternity or adoption leave, 15 months from the beginning of the leave. For shared parental leave, three months from the end of the shared parental leave.
• • The consequence: liability to refund the whole of the maternity, adoption or shared parental pay received, less any Statutory Maternity, Adoption or Shared Parental Pay.
• • The safety valve: where the employer considers that enforcing the provision would cause undue hardship or distress, it has the discretion to waive its rights to recovery.

The notification referred to is the one you give to qualify for occupational maternity pay in the first place. Para 15.15 requires you to notify your employer in writing, by the end of the 15th week before the expected date of childbirth, that you intend to return to work with the same or another NHS employer for a minimum period of three months after your maternity leave has ended. In other words, the repayment rule enforces the promise you made to qualify for the enhanced pay.

What you keep and what is repayable

Paragraph 15.83 is a refund of maternity pay less any statutory maternity pay received. That wording is the key to understanding the money. NHS maternity pay has two layers (para 15.21):

The last 13 weeks of the 52 are unpaid leave, and weeks 27 to 39 are paid at the statutory rate only, so no occupational pay is made in those weeks and there is nothing in them to refund. In other words, repayment is concentrated on the first 26 weeks, which is when the NHS enhances your pay.

Notice that para 15.83 says "the whole of" the maternity pay, less statutory pay. It does not say the refund is pro rata to how long you stayed or how many weeks are left. If the trigger is met, the potential liability is the whole of the occupational element, not a proportion of it. That is why the waiver in the same paragraph matters.

The 15-month rule, with dates

The 15 months run from the beginning of your maternity leave, not from the baby's birth and not from the end of leave. If you take the full 52 weeks, your leave ends after 12 months, which leaves about three months of the 15-month window after you are due back. That arithmetic is the simplest way to see how the three-month minimum in 15.15 and the 15-month deadline in 15.83 fit together.

If you change your leave start date, for example because the baby arrives early, the 15 months run from the actual start of leave. Our maternity pay calculator shows the refund window end date for your own start date.

Worked example: £30,000 salary

This example uses an illustrative salary of £30,000 a year, which is £576.92 a week as average weekly earnings, 3 years' NHS service, and the 2026/27 statutory flat rate of £194.32 a week. The figures are gross, and come from the same engine as our NHS Maternity Pay Calculator. They are rounded to the penny, and small differences are possible from week-by-week rounding.

Now compare four routes through the same maternity leave:

Two things stand out. First, the difference between telling the truth up front and promising to return is exactly the occupational element, so the practical effect of the rule is that enhanced pay is only kept by someone who returns, unless the employer waives it. Second, a person who genuinely intended to return but whose circumstances changed is in the third row, and that is the situation in which a waiver request would be considered.

When you do not have to repay

The Handbook sets out several situations where the repayment rule does not bite, or does not apply:

• ✓ You return within the period. Para 15.83 only applies if you fail to return within 15 months of the beginning of maternity or adoption leave, or three months from the end of shared parental leave.
• ✓ You return to a different NHS employer. The rule refers to the same or a different NHS employer, so moving trust is fine.
• ✓ Your contract would have ended anyway. Para 15.86: if there is no right of return because the contract would have ended if pregnancy and childbirth had not occurred, the repayment rule does not apply.
• ✓ You said up front you would not return. Para 15.100: you receive pay equivalent to statutory pay instead, so there is no occupational pay to recover.
• ✓ Your employer waives recovery for undue hardship or distress, in whole or in part.
• ✓ You never qualified for the occupational scheme. If you have under 12 months' continuous service, you may be entitled to statutory pay only (para 15.103), which is not refundable under 15.83.

The undue hardship waiver

The waiver is the single most useful part of the paragraph for anyone in difficulty, and the least well understood. The wording is that, where the employer considers enforcing the provision would cause undue hardship or distress, the employer has the discretion to waive their rights to recovery. A few practical points follow from that wording:

If you think the request was handled unfairly, for example it was ignored or refused without consideration, the grievance procedure is the route for a complaint about how it was handled. Because the waiver is a discretion, do not expect a grievance to force a particular outcome.

Telling your employer you will not return

If you already know before leave starts that you will not go back, paragraph 15.100 gives a clean route: you tell your employer, you are paid an amount equivalent to Statutory Maternity Pay, and you owe nothing back. You still have the full 52 weeks of leave, because para 15.105 gives every employee the right to 52 weeks whether or not they return to NHS employment. The cost is the enhanced pay, which in our example is about £6,300.

The harder case is when you genuinely planned to return and your plans changed. The Handbook does not say that you lose your enhanced pay going forward or that you must repay immediately. What it says is that the liability arises if you fail to return within the period. Talk to HR as early as you can so that pay, your leave end date and any waiver request are handled together and nothing is paid on a mistaken assumption.

If you have changed your mind: what to do

• ✓ Read your trust's maternity policy and the written confirmation of your leave and pay entitlement you were given under para 15.20. Look for the repayment wording, because trusts apply 15.83 through their own policy.
• ✓ Work out your 15-month date from the actual start of your leave, and what you have been paid so far, using the calculator.
• ✓ If there is any chance of staying in the NHS, check what counts as returning. Moving trust counts. A career break may be an alternative, see the career break guide.
• ✓ Ask HR in writing how your trust treats annual leave at the end of leave, a return followed by resignation within three months, and part-time or bank return.
• ✓ If you will not return, ask for the repayment calculation in writing, and put any hardship waiver request in writing before any deduction is made.
• ✓ Check your contractual notice period before you resign. See notice periods in the NHS.
• ✓ Check the pension side. Time on maternity leave counts for NHS Pension purposes in particular ways, see NHS Pension and maternity leave.

Questions the Handbook does not answer

It is better to be clear about what is not settled than to guess. On the wording of Section 15 we cannot tell you:

• • Whether annual leave at the end of maternity leave counts as returning. Para 15.95 allows accrued annual leave to be taken before or after the leave period by agreement, but the Handbook does not say how that interacts with the 15-month deadline.
• • What happens if you return and leave within three months. The three-month commitment is in 15.15(c), and the repayment trigger is in 15.83, and they are worded differently.
• • Whether the refund is gross or net, and how tax already deducted is dealt with.
• • Whether a part-time, bank or reduced-hours return counts. The Handbook refers only to returning to work. Para 15.80 says employers must facilitate a return on different hours wherever possible, which supports the view that a flexible return is a return, but check with HR.
• • How your trust will recover any repayment, such as from final pay or by instalments.

For each of these, ask HR in writing and keep the reply. If you are a union member, ask your representative to check how your trust has handled similar cases.
