Qualifying for Statutory Maternity Pay: Continuous Service & LEL Rules

Understanding leave rights vs. pay rights

When planning for parental leave, many employees make the mistake of blending their time-off rights with their cash-repayment rights. Under UK employment law, these are treated as completely independent concepts:

• Statutory Maternity Leave (SML). A day-one job-protection right. Every female employee has a legal right to take up to 52 weeks of leave, regardless of how long they have worked at the company or how much they earn.
• Statutory Maternity Pay (SMP). A conditional cash right. It is not an automatic day-one right and features strict compliance gates that must be satisfied during a specific week of your pregnancy.

The two mandatory eligibility hurdles

To qualify for SMP, your payroll profile must clear two strict statutory hurdles simultaneously:

1. The Continuous Service Test. You must have worked for your employer continuously for a minimum of 26 weeks leading into your Qualifying Week. The Qualifying Week is explicitly defined as the 15th week before your expected week of childbirth. Effectively, this means you must have been employed by your company before you became pregnant.
2. The Lower Earnings Limit Test. Your calculated Average Weekly Earnings (AWE) during your specific 8-week lookback window must be equal to or higher than the active Lower Earnings Limit of £129.00 per week.

Deconstructing the 39-week payment matrix

If your profile successfully clears both tests, your employer is legally bound to process your statutory payments across a fixed 39-week timeline. The cash flows through two distinct calculation layers:

• Phase 1 — Weeks 1–6. 90% of your true unrounded AWE, completely uncapped.
• Phase 2 — Weeks 7–39. Lower of 90% of your AWE or the flat cap of £194.32 per week.

For a professional with an average weekly income of £1,000, the first 6 weeks yield an uncapped gross payment of £900 per week. On week 7, pay drops to the flat national cap of £194.32 per week, where it remains until the 39-week paid timeline ends. The final 13 weeks of statutory leave are completely unpaid.

Crucial notices and evidence timelines

To secure your SMP without processing delays, you must provide your employer's HR department with two formal compliance items:

• The MAT B1 Certificate. A mandatory medical form issued by your midwife or doctor, typically distributed after the 20th week of pregnancy, confirming the official expected due date.
• Advance notice. You must formally notify your employer of your intention to start your leave at least 15 weeks before your due date, allowing payroll teams to lock down your lookback calculation window cleanly.

When you fail the gates — Maternity Allowance

If you fail either of the eligibility gates — for example because you are self-employed, recently changed employer, or your AWE falls below the LEL — you are not without recourse. The government-funded Maternity Allowance (MA) pays up to the same £194.32 weekly rate (subject to its own contribution-based eligibility) and is claimed directly through Jobcentre Plus rather than your employer.
