SMP uses your Average Weekly Earnings (AWE)—we use your weekly gross as a proxy. Statutory weekly rate (£) is updated each April—editable below. NHS occupational bands are a simplified pattern; your trust may differ.

SMP formula (summary)
What is NHS maternity pay?
Most NHS staff receive Statutory Maternity Pay if they qualify (service, earnings, timing) plus occupational maternity pay which tops up salary for a defined number of weeks.
SMP vs OMP
SMP follows UK law (90% then lower of statutory rate or 90%). OMP is employer-specific—often full pay, then half pay + SMP, then SMP only.
Eligibility (simplified)
- Continuous employment with the employer for long enough (26 weeks into “qualifying week” is typical for SMP).
- Enough earnings above the Lower Earnings Limit (LEL)—check current HMRC figures.
- Give notice and evidence in time.
