Maternity protection requires employers to do far more than merely observe statutory deadlines: it mandates proactive health and safety risk assessments, strict adherence to working time and rest rules, and robust compliance with statutory leave, pay, and non-discrimination legislation.
Statutory Maternity Leave & Compulsory Periods
Under the Maternity and Parental Leave etc. Regulations 1999 (MPLR) and the Employment Rights Act 1996 (ERA 1996), all pregnant employees are entitled to up to 52 weeks of Statutory Maternity Leave (SML) from Day 1 of employment, irrespective of length of service.
| Period | Statutory Provision |
|---|---|
| Up to 11 weeks before the Expected Week of Childbirth (EWC) | Earliest an employee can choose to commence Statutory Maternity Leave (unless triggered earlier by pregnancy-related illness in the 4 weeks before EWC or premature birth) |
| First 2 weeks following childbirth (4 weeks for factory workers) | Compulsory Maternity Leave – absolute statutory prohibition on permitting the employee to work |
| Up to 26 weeks | Ordinary Maternity Leave (OML) – employee maintains right to return to the exact same job |
| Up to 52 weeks | Additional Maternity Leave (AML) – employee maintains right to return to the same job or a suitable alternative role on no less favourable terms |
If an employee is absent from work due to a pregnancy-related illness at any time during the 4 weeks before the Expected Week of Childbirth (EWC), their Statutory Maternity Leave automatically commences on the day following the first day of that absence.
Working Time Limits and Health & Safety Protections
For pregnant and breastfeeding employees, specific protections apply under the Management of Health and Safety at Work Regulations 1999 (MHSWR) alongside the Working Time Regulations 1998 (WTR) and the Equality Act 2010:
- An entitlement to reasonable paid time off for antenatal care appointments (including medical examinations and relaxation classes recommended by a registered medical practitioner, midwife, or health visitor) pursuant to Section 55 ERA 1996,
- Protection against unsuitable night work: where an occupational health specialist, GP, or midwife certifies that night work poses a risk to health and safety, the employer must transfer the employee to suitable day work or suspend her on full pay under Section 67 ERA 1996,
- Strict observance of uninterrupted rest breaks (minimum 20 minutes for shifts over 6 hours under Regulation 12 WTR) and daily rest (minimum 11 consecutive hours in each 24-hour period under Regulation 10 WTR),
- Suitable rest and private facilities for pregnant and nursing mothers to rest and express milk (under the Workplace [Health, Safety and Welfare] Regulations 1992).
Workplace Risk Assessment
Regulation 16 of the Management of Health and Safety at Work Regulations 1999 (MHSWR) requires employers to assess the risks to women of childbearing age across the workforce. Once an employee gives written notification of pregnancy, childbirth within the previous six months, or breastfeeding, the employer must carry out a specific, individual workplace risk assessment.
If an unavoidable hazard or significant risk is identified (e.g. heavy lifting, exposure to toxic substances, prolonged standing, severe physical fatigue, or high stress), the employer must follow a strict statutory hierarchy:
- Adjust and modify working conditions or hours of work,
- Offer suitable alternative employment on terms that are not substantially less favourable,
- Medical / Health and Safety Suspension on full pay under Section 67 of the Employment Rights Act 1996 as a last resort.
Suspending an employee without having thoroughly explored and exhausted reasonable workplace adjustments and alternative redeployment options may constitute unlawful maternity discrimination under Section 18 of the Equality Act 2010.
Medical Suspension vs. Pregnancy-Related Sickness
A vital legal and financial distinction exists between a statutory medical suspension on maternity grounds and incapacity for work due to pregnancy-related sickness:
- Medical / Health & Safety Suspension (Section 67 ERA 1996): Occurs where the employee is medically fit to work, but the employer cannot provide a safe working environment. The employee is entitled to full remuneration (normal full pay) for the entire duration of the suspension.
- Pregnancy-Related Illness: Occurs where the employee is medically unfit to work due to illness. The employee is subject to standard contractual sick pay or Statutory Sick Pay (SSP) under the Social Security Contributions and Benefits Act 1992.
Crucially, under the Equality Act 2010, pregnancy-related sickness absences must be recorded separately and must not be counted toward standard disciplinary or capability absence triggers.
Remuneration and Statutory Maternity Pay (SMP)
| Situation | Benefit / Entitlement |
|---|---|
| Health and safety suspension outside maternity leave | Full normal pay (statutory remuneration under Section 68 ERA 1996) |
| Statutory Maternity Pay (SMP) – First 6 weeks | 90% of the employee's Average Weekly Earnings (AWE) with no statutory cap |
| Statutory Maternity Pay (SMP) – Next 33 weeks | Statutory standard rate (or 90% of AWE, whichever is lower) |
| Remaining 13 weeks of Statutory Maternity Leave | Unpaid (unless contractual enhanced maternity pay applies) |
| Illness unrelated to pregnancy before the 4-week window | Statutory Sick Pay (SSP) / Contractual Sick Pay |
To qualify for SMP, an employee must have been continuously employed for at least 26 weeks up to the 15th week before the Expected Week of Childbirth (the "qualifying week") and earn at least the Lower Earnings Limit (LEL). Average Weekly Earnings are calculated over an 8-week statutory assessment period, requiring accurate, audit-proof payroll and historical working time data.
HMRC Recovery Scheme for Employers
Employers are responsible for paying SMP directly to employees through standard payroll (PAYE). However, businesses recover the vast majority of these statutory payments from HM Revenue & Customs (HMRC):
- Standard Employers: Can recover 92% of all SMP paid by offsetting it against monthly PAYE and National Insurance payments to HMRC.
- Small Employers' Relief (SER): Employers who paid £45,000 or less in total Class 1 National Insurance contributions in the relevant tax year can recover 103% (100% of SMP plus an additional 3% compensation for the secondary Class 1 NICs incurred).
Reclaiming statutory maternity pay accurately requires transparent, compliant documentation of qualifying dates, notices, and payment schedules.
Enhanced Protection Against Redundancy and Dismissal
Dismissing an employee, selecting them for redundancy, or subjecting them to any detriment because of pregnancy, childbirth, or maternity leave is automatically unfair under Section 99 ERA 1996 and unlawful discrimination under Section 18 of the Equality Act 2010.
Under the Protection from Redundancy (Pregnancy and Family Leave) Act 2023, enhanced statutory redundancy protection applies:
- From the date the employee notifies the employer of the pregnancy,
- Throughout the entire 52 weeks of Statutory Maternity Leave,
- Extending up to 18 months from the exact date of childbirth.
If a redundancy situation arises during this protected period, the employer has an absolute statutory obligation to offer the employee any suitable alternative vacancy that exists, in priority over other employees and without requiring competitive interviews.
Annual Leave and Accrual of Contractual Rights
Under the Working Time Regulations 1998 and Regulation 9 of the MPLR 1999, an employee on Statutory Maternity Leave continues to benefit from all existing terms and conditions of employment (except remuneration), including the full accrual of statutory annual leave (5.6 weeks statutory minimum) and any contractual holiday entitlements.
Employers cannot compel an employee to take annual leave during maternity leave, nor can accrued leave be forfeited because the employee was absent on maternity leave. Employees are entitled to carry forward untaken statutory leave into the subsequent holiday year.
