① Your Legal Rights on Return

Your rights when returning from maternity leave are protected by law and depend on when you return relative to your total leave period. The key distinction is whether you return within the first 26 weeks (Ordinary Maternity Leave) or after 26 weeks (Additional Maternity Leave).

Your rights on return at a glance

Returning within 26 weeks (OML)Right to return to the same job on the same terms and conditions — same hours, same pay, same responsibilities.

Returning after 26 weeks (AML)Right to return to the same job, or if that is not reasonably practicable, a suitable alternative on equivalent or better terms. Your employer must demonstrate the original role is genuinely unavailable.

Change of return dateYou must give 8 weeks’ written notice to change your return date. If you want to return earlier than planned, the same 8-week notice applies.

Contractual benefitsAll contractual benefits (pension, private medical, car allowance etc.) must be reinstated exactly as before your leave.

Redundancy during leaveIf your role becomes redundant during or immediately after maternity leave, you must be offered any suitable alternative vacancy ahead of other employees. Failure to do this is automatically unfair dismissal.

Breastfeeding at workYour employer has a duty to provide a suitable private space (not a toilet) for expressing milk at work, and to risk-assess your working environment if you are breastfeeding.

② Requesting Flexible Working

Since April 2024, all employees have had the right to request flexible working from their first day of employment — you no longer need to have worked for 26 weeks before making a request. You can make two flexible working requests per year. Maternity leave is commonly the trigger for a first flexible working request, because return to work is the natural moment to negotiate new arrangements.

What counts as flexible working

A flexible working request can cover: reduced hours or part-time working; compressed hours (full-time hours in fewer days); remote or hybrid working; flexitime; term-time working; job sharing; or a change in start or finish times. You can request any combination of these.

How the process works

Submit your request in writing State the change you want, the date from which you want it, and what effect (if any) you think it will have on the business and how this might be dealt with. Keep a copy.

Your employer has 2 months to respond They must deal with the request in a reasonable manner. They can accept it, agree a different arrangement, or refuse — but a refusal must be based on one of 8 specific business grounds set out in the law.

If they refuse, ask for the grounds in writing The 8 permissible grounds for refusal are specific. An employer cannot refuse simply because they prefer people to be in the office. If the stated reason does not match a genuine business ground, you may have a claim. ACAS can advise.

Agreed changes become permanent contractual changes A flexible working arrangement that is agreed becomes a permanent change to your contract unless explicitly agreed as temporary. It cannot be reversed by the employer without your agreement and a new contractual change process.

💡 Put the business case first: The most effective flexible working requests explain how the arrangement can work for the business — not just why it suits you. Include how you plan to handle team collaboration, coverage during your off-hours or days, and any precedent for similar arrangements in your organisation. A request framed around solutions tends to land better than one framed around personal need.

③ Sorting Childcare Before You Return

Childcare is typically the most complex logistical element of returning to work. The key mistakes: starting to look too late, underestimating waiting lists, and not budgeting correctly for the costs alongside entitlements. Aim to have childcare confirmed at least 3 months before your return date.

The key steps and timeline

Register with nurseries 6–12 months before you need a place Oversubscribed nurseries in urban areas can have waiting lists of 12 months or more. Register your interest early — you do not need a confirmed return date to join a waiting list. Call around before your baby is 6 months old if possible.

Apply for your free childcare hours code If your child is eligible for funded hours (see our free childcare hours guide), apply for your code at childcarechoices.gov.uk at least a term before you need it. Give the code to your provider promptly — they need it to claim your funding.

Set up Tax-Free Childcare Apply at the same time you apply for free hours — the process is combined. Start depositing into your TFC account from day one of childcare to maximise the government top-up. See our TFC guide for the full details.

Do the settling-in sessions before your return date Most nurseries offer 2–5 settling-in sessions before your child starts full time. Schedule these in the 2–3 weeks before your return so your child has time to adjust without you also managing your first week back at work simultaneously.

④ Annual Leave Accrued During Maternity Leave

You accrue your full statutory annual leave entitlement (5.6 weeks) throughout your entire maternity leave, including any unpaid period. You also accrue any enhanced annual leave your employer offers, though check your contract as some enhanced entitlements accrue only during paid leave. This accrued leave must not be lost — it must either be taken before or after maternity leave, or in some cases carried into the next leave year.

Many parents choose to take their accrued annual leave immediately before their return date, effectively extending their time away from work beyond the maternity leave period without extending the maternity leave itself. Discuss with your employer how they prefer to handle your accrued leave — they cannot simply withhold it, but the timing of when it is taken can be negotiated.

⑤ The Month Before You Go Back

Return-to-work preparation checklist

Confirm your return date in writing — and confirm any flexible working arrangement agreed is reflected in a written contract amendment

Check your salary — confirm any pay rises that occurred during your absence have been applied and that your return salary is correct

Agree how annual leave will be handled — whether accrued leave is taken before return, paid out or carried over

Update your childcare code — reconfirm your TFC account and free hours code if a reconfirmation is due

Complete settling-in sessions at your childcare provider and adjust your child’s schedule to match your working hours

Consider a KIT day — using one of your 10 Keeping in Touch days in the week before you return can ease the transition back by catching up with colleagues and understanding what has changed

Notify your employer if breastfeeding — they have a duty to provide suitable facilities and risk-assess your environment

Plan your first week — keep commitments light in the first week back if possible; the adjustment is real for both you and your child

⑥ The Emotional Side

Most guides to returning from maternity leave focus on the legal and logistical — the rights, the childcare codes, the flexible working process. The emotional dimension is harder to systematise but is the thing most parents say they were unprepared for.

Returning to work after maternity leave involves a genuine identity shift. You are now managing two significant roles simultaneously — parent and worker — in a way that is not the same as either role before. The difficulty of this is normal and does not indicate that you are doing it wrong. Most parents who found the first weeks back hard went on to find a rhythm that worked for them and their family.

Some things that tend to help: giving yourself explicit permission to find it hard without interpreting that as a sign the whole arrangement is wrong; having a regular check-in point — typically 6–8 weeks — at which you honestly assess how it is going and whether anything needs to change; and being honest with your employer if the workload or schedule is not working as agreed.

🤝 Guilt is normal — and it fades: The feeling of guilt at leaving your child — particularly in the first weeks — is near-universal among returning parents and is not evidence that you are making the wrong choice. Children in good quality childcare do well. Most parents report that after 4–6 weeks, both they and their child have adjusted and the acute difficulty of the initial transition has passed.

Summary

Know your rights, submit your flexible working request early, get childcare sorted 3 months ahead, and plan the first week gently.

The practical preparation for returning from maternity leave is manageable if done in the right order and at the right time. The sequence that works: decide your return date and any flexible working arrangement at least 2–3 months before your return; confirm childcare at the same time; apply for free hours and TFC; use any accrued annual leave to extend your time away or ease back in gradually. Then plan the first week realistically.

Frequently Asked Questions

My employer has changed my role while I was on maternity leave. Is this legal?+

It depends on when you return and why. If you return within the first 26 weeks of leave, you have an absolute right to your exact same job on your exact same terms. If you return after 26 weeks, your employer can offer a suitable alternative only if your original role is genuinely not reasonably practicable to return to — and the alternative must be on equivalent or better terms. If you believe your role has been changed unfairly, contact ACAS immediately for free advice before your return date.

Can my employer refuse my flexible working request?+

Yes — but only on one or more of 8 specific business grounds: burden of additional costs; inability to reorganise work among existing staff; inability to recruit additional staff; detrimental impact on quality; detrimental impact on performance; detrimental effect on ability to meet customer demand; insufficient work during the proposed hours; planned structural changes. A refusal must state which of these grounds applies and why. If the stated reason does not genuinely correspond to one of these, you may be able to challenge the decision. ACAS (acas.org.uk) can advise free of charge.

Do I have to repay my enhanced maternity pay if I leave shortly after returning?+

Only if your contract includes a clawback clause requiring you to return for a minimum period. Clawback clauses are common in enhanced maternity pay schemes — typically requiring a return of 3–12 months. If such a clause exists, you would need to repay the enhanced element (above SMP) if you left within that period. SMP itself is never repayable. Check your contract carefully before making any decision — and if in doubt, ask HR to confirm the clawback terms in writing.

I’m finding it very hard emotionally after returning. When does it get easier?+

The first 4–6 weeks of return are typically the hardest for both parent and child. Most parents who have returned to work report that by around 6–8 weeks, a routine has established itself and the acute difficulty of the transition has eased significantly. If you are finding it genuinely unmanageable beyond the initial adjustment period — particularly if you are experiencing anxiety, low mood or inability to function at work — speak to your GP. Postnatal anxiety and depression can be triggered or exacerbated by the return-to-work transition and respond well to support.
