The UK gender pay gap is 0.9% before 30. By your fifties it is 12.5%. Career breaks for childcare turn a manageable gap into a £113,000 hole at retirement. The maths is harder, not unwinnable.

Key takeaways
The UK gender pay gap is 0.9% in your twenties and 12.5% by your fifties. The widening tracks the years women take out of work for childcare, not any change in skill or effort.
The gender pension gap is now £113,000 between the average woman and man at retirement. The median woman retires with £173,000, the median man with £286,000.
The £10,000 auto-enrolment earnings trigger excludes 2.5 million UK women (17% of female employees) from any workplace pension at all, versus 8% of male employees. This is a policy choice, not a behavioural one.
The individual playbook works around the structural problem, it does not solve it. Maximise contributions in your twenties when the gap is small, split parental leave with your partner, fund a SIPP during career breaks, and use salary sacrifice once back in work.
