There is no single occupational maternity policy for every civil servant. The government guide describes 26 weeks at full pay, with longer offers in some departments. Confirm your department’s eligibility and return conditions before including it. Northern Ireland Civil Service terms are separate.

Civil service maternity pay: the scheme modelled
These stages assume the relevant occupational conditions and separate SMP rules are met.
Only included after you confirm eligibility.
For an eligible employee on a 26-week offer.
Adjust full-pay weeks if your policy differs.
The calculator uses 2026/27 statutory and pension assumptions beyond this year where future rates are unknown. Pay rises, salary sacrifice, student loans, Maternity Allowance, shared parental leave, pension benefit accrual and one-off payroll adjustments are not modelled. A simplified fixed pension percentage is applied to paid earnings. Check your actual policy and payslip.
Civil service maternity pay questions
Do all civil servants get 26 weeks at full pay?
No. The government guide describes a common full-pay offer, but entitlement is set by your department. Some departments offer more weeks. Until you confirm that you meet your policy’s conditions, the calculator shows SMP only.
Can I model 39 weeks of full pay?
Yes. Change the full-pay weeks to the number in your department’s policy and confirm eligibility. The calculation treats full pay as including SMP, not an extra payment on top of it. Enter 0 to model statutory pay alone.
Will I have to repay enhanced pay?
Your department’s policy decides any return commitment and occupational-pay recovery. Confirm those conditions before ticking the eligibility box, especially if you might resign or return on different hours. The calculator does not establish that you can keep the enhanced element.
Which pension is used?
The suggestion follows the 2026/27 alpha member contribution bands. The rate is applied to paid earnings for an estimate of tax relief and take-home. Other schemes, pension benefit accrual and unpaid-leave contributions need checking separately.
Can I use a different employer scheme?
Yes. Use the general maternity pay calculator to enter the stages in your own policy. The figures here are estimates for the named agreement, not an entitlement decision.
