Latest date for starting work in order to qualify for Statutory Maternity Pay

In order to qualify for Statutory Maternity Pay, a woman must have been working for her employer technically for 26 weeks by the end of the 'Qualifying Week' (this being 15 weeks before the expected week of childbirth). In effect, put simply, this is 41 weeks service by the baby's due date.

Maternity Pay Calculation Period

Statutory maternity pay is paid for the first 6 weeks at 90% of average weekly earnings, followed by a further 33 weeks at the lesser of 90% of average weekly earnings or the applicable statutory rate which varies each year. However, in order to calculate average earnings, you need to understand which period you are required to refer. This will be the period of 8 weeks running up to the qualifying week.

Deadline for employee to notify you she is pregnant and wishes to take maternity leave

This is the last date by which the employee must inform the employer of the fact that they are pregnant, their expected week of childbirth (almost always submitted on a form MAT B1) and their intended maternity leave start date.

Earliest Date for starting Maternity Leave

Maternity leave cannot ordinarily commence until this date (which is 11 weeks before the expected week of childbirth). However, if the baby is born before this date, maternity leave automatically starts on the day after childbirth.

Maternity leave automatic trigger if sick

Maternity leave will start automatically if the employee is absent from work for a pregnancy related reason on or after this date (which is 4 weeks before the expected week of childbirth).

Maternity Leave Obligations

As an employer you need to understand the law surrounding maternity leave, your obligations, and the rights of your employees. Staff who fall pregnant in the UK are entitled to Statutory Maternity Leave (SML) of 52 weeks. This is made up of 26 weeks of Ordinary Maternity Leave and 26 weeks of Additional Maternity Leave.

Your employees are entitled to SML no matter how long they have worked for you, how many hours they work or how much you pay them.

As a client of Citation, we will help guide you through this complex and unsettling period. We understand that losing a key employee for this length of time can put real pressure on any business. If you’re a small company then dealing with an absent employees workload can be very challenging, especially if you are not an HR expert. You also need to be aware of issues relating to unfair dismissal, redundancy and discrimination before taking any action.
