Read the policy-specific methodology note

Birth baseline

The central case starts from about 650,000 UK births and models higher statutory paid partner and parental leave.

  • ONS records 594,677 England and Wales births.
  • UK-wide births are scaled upward.
  • Take-up assumptions drive the estimate.

Core trade-offs

Parents gain time and income security. Taxpayers fund statutory payments and employers fund cover. Poor design can increase hiring risk for likely parents.

  • Parents gain paid time.
  • Taxpayers and employers pay.
  • Hiring discrimination risk rises.

Illustrative fiscal impact

+GBP 0.8bn to +GBP 8.0bn. Central estimate: +GBP 2.8bn.

  • Positive numbers mean public-finance pressure; negative numbers mean Exchequer savings.
  • Gross costs are separated from tax, NI and benefit offsets.
  • Private business costs are not automatically fiscal costs.
  • Behavioural responses widen the range materially.
  • This is not an official costing.

Economic impact by 2027-28

  • Jobs: May support parental attachment, but small firms face cover and hiring risk.
  • Wages: Raises paid leave income for new parents, especially partners.
  • Prices: Small aggregate price effect; employer cover costs may pass through.
  • GDP / productivity: Likely negative short run from absence cover; long-run participation gains uncertain.

Assessment

Paid parental leave can reduce unfair family penalties, but it does not pay for itself in the short run. The fiscal cost depends on replacement rates, eligibility, employer recovery and take-up by second parents.

Confidence: Low. Take-up, replacement rates and employer cover costs are the weak assumptions.

Main risks

  • Take-up uncertainty: Partner take-up can change sharply if pay is more generous.
  • Cover costs: Employers need temporary cover or accept lower output.
  • Discrimination risk: Employers may perceive higher expected costs for likely parents.

Safeguards

  • Use individual non-transferable quotas.
  • Reimburse small firms promptly.
  • Monitor hiring by age and gender.
