UK Maternity Leave Guide 2026 — Pay, Rights, Returning to Work

1. How long is UK maternity leave?

UK maternity leave is up to 52 weeks total, split into two phases:

• Ordinary Maternity Leave (OML): First 26 weeks. Stronger rights to return — you have the right to return to your same job on the same terms.
• Additional Maternity Leave (AML): Weeks 27-52. You have the right to return to your same job, or if not reasonably practicable, a similar job with no less favourable terms.

All UK employees are entitled to the full 52 weeks regardless of length of service. The eligibility rules apply only to PAID leave (SMP), not to the length of leave you can take.

Most UK women take 6-12 months — about 70% return before the full 52 weeks because the final 13 weeks are unpaid unless you have an enhanced contractual scheme.

2. UK Statutory Maternity Pay rates 2026/27

UK SMP has two phases over 39 weeks:

SMP is taxed as normal salary income with income tax and NI deducted. The 90% Phase 1 rate is uncapped, so high earners can receive substantial amounts during the first 6 weeks. From week 7, most middle and high earners drop to the £187.18/week cap (because 90% of their AWE exceeds it).

Use our UK Statutory Maternity Pay Calculator for total over 39 weeks and net pay calculation.

3. UK SMP eligibility 2026

You qualify for UK SMP if you meet ALL of these conditions:

1. Continuous employment: 26 weeks with the same employer by the end of the qualifying week (15 weeks before your due date).
2. Earnings test: Average weekly earnings of at least £125 (the 2026/27 Lower Earnings Limit) in the 8 weeks before the qualifying week.
3. Notice: 28 days' notice to your employer of your intended start date.
4. MATB1 form: Maternity certificate from your midwife or GP (issued from week 21 onwards).
5. Still pregnant or recently given birth in the qualifying week (15 weeks before due date).

If you don't qualify for SMP:

You may qualify for Maternity Allowance from the government rather than SMP from your employer. Maternity Allowance has slightly different rules — most relevantly, you can qualify if you've worked for any employer (not just the same one) for 26 weeks in the 66 weeks before your due date. Pays the same flat rate as SMP (£187.18/week or 90% of earnings, whichever is lower) for 39 weeks.

Self-employed women may qualify for Maternity Allowance if they've paid Class 2 NI for 13 of the 66 weeks before due date.

4. When to start UK maternity leave

You can start UK maternity leave anytime between:

• Earliest: 11 weeks before your due date
• Latest: The day after birth (or earlier if pregnancy-related sickness in the 4 weeks before due date triggers it automatically)

Common UK start patterns:

• 1-4 weeks before due date: Most common. Some preparation time before birth without using too much paid leave pre-baby.
• 4-6 weeks before due date: If your role is physically demanding or stressful, or you're feeling unwell.
• The day after birth: If you want maximum paid leave after birth. Less common because labour timing is unpredictable.
• 11 weeks before due date: Rare. Mostly for high-risk pregnancies or extreme physical demands.

Strategic note: starting later means more paid leave AFTER birth (for childcare); starting earlier means more leave BEFORE birth (for preparation). Most candidates I've worked with optimise for post-birth time, starting maternity 1-3 weeks before due date.

5. Enhanced contractual maternity pay schemes

Many UK employers offer enhanced contractual maternity pay above the statutory minimum. Common patterns:

• Modest: Full pay for first 6 weeks (instead of 90%), then standard SMP. Adds 10% on the 6-week 90% rate.
• Standard: Full pay for 13 weeks, then SMP. Common in financial services, professional services.
• Generous: Full pay for 26 weeks, then SMP. Common in larger UK corporates and public sector.
• Generous + half pay: Full pay for 6 weeks + half pay for weeks 7-26 + SMP. Common in NHS and public sector.
• Tiered by tenure: Different enhanced rates based on length of service. Less common.

Enhanced packages usually have conditions — most commonly that you return to work for a minimum period (typically 3-6 months) afterwards, otherwise you may have to repay the enhancement. Read the contract clause carefully before relying on the higher figure.

Use our UK SMP Calculator with the enhanced contractual mode to model the total package value.

6. How to notify your employer

UK maternity leave notification is a structured process:

1. Notice deadline: By the 15th week before your due date, tell your employer in writing that you're pregnant, your due date, and your intended maternity leave start date.
2. MATB1 form: Provide your maternity certificate (issued by midwife/GP from week 21).
3. Confirmation: Your employer must confirm in writing within 28 days the date your maternity leave will end (typically week 52 or your stated return date).
4. Changing the start date: Allowed with 28 days' notice (or as much notice as is reasonably practicable).
5. Changing the end date: Allowed with 8 weeks' notice if returning earlier than originally planned.

Always notify in writing (email is fine). Verbal notification doesn't trigger the formal protections. Save copies of all correspondence.

7. Your rights during UK maternity leave

Your contractual rights continue during maternity leave with specific exceptions:

• Holiday accrual: You continue accruing 5.6 weeks of statutory annual leave during maternity leave. Some contractual leave above this may also accrue. Take it before, after, or carry over (some carry-over rules apply).
• Pension contributions: Employer must continue paying their pension contributions at your pre-leave salary level during paid SMP (39 weeks). Your contributions are based on actual SMP received.
• Pay rises: Any pay increase that applies to your role/grade during your maternity leave applies to you. You're entitled to be considered as if working.
• Bonus: Pro-rated based on time worked vs on leave, depending on bonus structure. Check your contract.
• Benefits in kind: Continue (e.g., private medical insurance, company car).
• Right not to be dismissed: You cannot be dismissed for reasons related to pregnancy or maternity leave.
• Right to suitable alternative work: If your role becomes redundant during maternity, you have a stronger right to be offered suitable alternative employment than other staff.

See our UK employment rights guides for full statutory protections.

8. KIT (Keeping In Touch) days

KIT days let you work up to 10 days during your maternity leave without losing SMP or affecting your maternity rights.

Common KIT day uses:

• Training days (especially if returning to a changed role)
• Key meetings (board meetings, important client meetings)
• Project handover before AML
• Testing the waters before full return
• Maintaining client relationships in client-facing roles

KIT day rules:

• Voluntary on both sides — neither employer nor you can compel them
• Maximum 10 days during the entire 52-week leave period
• Any work counts as a full KIT day (even half a day or an evening event)
• SMP continues unaffected
• Pay for KIT days is negotiable — sometimes full salary on top of SMP, sometimes including SMP value

Negotiate KIT day pay before agreeing — common arrangements: full daily salary on top of SMP for that day, or daily salary minus SMP value, or "consultancy day rate" for senior staff. Strong leverage to negotiate full-pay arrangements.

9. UK Shared Parental Leave

Shared Parental Leave (SPL) lets you give some of your maternity leave and pay to your partner. Both parents must qualify (similar 26-week tenure rules to SMP).

Total SPL entitlement:

• Up to 50 weeks of leave to split between parents (52 weeks total minus 2 weeks of compulsory maternity leave)
• Up to 37 weeks of pay (39 weeks SMP minus 2 weeks of compulsory maternity)
• Pay rate: lower of £187.18/week or 90% of earnings (same as SMP weeks 7-39)
• Can be taken in flexible blocks, not all at once
• Both parents can be off at the same time, or in sequence

SPL trade-offs:

• The mother loses access to the 90% first 6 weeks rate for any leave converted to SPL
• More flexibility for the family overall
• The partner can have meaningful paid time off (more than statutory 2-week paternity leave)
• Worth modelling both options before the qualifying week

SPL uptake in the UK has been lower than expected — about 1-2% of eligible families use it. Many families find the financial trade-off (mother loses 90% rate) doesn't favour SPL unless the partner's salary is similar to or higher than the mother's.

10. Returning to work after UK maternity leave

Your right to return:

• After OML (week 26): Right to return to your same job on the same terms.
• After AML (week 27-52): Right to return to your same job, or if not reasonably practicable, a similar job on terms no less favourable.
• Salary: At least your pre-leave salary, plus any pay rises that applied to your grade during your absence.
• Continuity of service: Maintained — your maternity leave counts as continuous service.

Return arrangements:

• Standard return: Just go back on your originally agreed return date. No specific notice needed unless returning earlier than 52 weeks.
• Earlier return: 8 weeks' notice required if returning before your originally stated end date.
• Flexible working request: You can request flexible working from day 1 of returning. Common requests: reduced hours, hybrid working, term-time only, compressed week.
• Resigning instead of returning: Allowed; you keep all SMP/SPP received. Notice rules apply.

Many UK women request flexible working when returning. The right to request flexible working from day 1 of employment (changed in April 2024) makes this easier — though employers can still refuse on business grounds.

11. Financial planning for UK maternity leave

UK maternity pay drops significantly during leave for most middle and high earners. Financial planning matters:

• Save during pregnancy: Aim for 3-6 months of essential expenses in savings. ISA allowance helps (£20,000/year tax-free).
• Reduce monthly fixed costs: Pay down credit cards, review subscriptions, switch utility providers before leave.
• Time bonuses for the AWE window: Bonuses paid in the 8 weeks before the qualifying week count toward AWE — can boost SMP rate.
• Salary sacrifice considerations: Aggressive salary sacrifice in the AWE window REDUCES SMP. Pause sacrifice during qualifying period if possible.
• Tax-free childcare planning: Eligible if returning to paid work — register early.
• Pension during leave: Employer continues at full rate; your contributions drop. Worth modelling impact on long-term pension growth.
• Resigning during/after leave: You keep SMP received. If contractual enhanced pay was repayable on non-return, check terms before deciding.
