Policy baseline

The costings allocate GBP 4.06bn to child-poverty and welfare fairness measures by 2028-29.

  • Targets low-income families and renters.
  • Housing Benefit and LHA interactions are included by party.
  • Take-up and rent effects are uncertain.

Core trade-offs

The direct beneficiaries are low-income families and renters. The costs fall mainly on taxpayers through higher benefit spending. The main economic question is poverty falls but housing supply constraints remain.

  • Low-income families and renters gain most directly.
  • Costs fall mainly on taxpayers through higher benefit spending.
  • Key risk: poverty falls but housing supply constraints remain.

Fiscal impact by 2028-29

+GBP 2.5bn to +GBP 7.0bn. Central estimate: +GBP 4.1bn.

  • Positive numbers mean net fiscal cost; negative numbers mean Exchequer savings.
  • Main channel is the scored tax, spending or delivery change.
  • Offsets depend on tax receipts, behaviour and pass-through.
  • Range reflects uncertain implementation and economic response.
  • This is not an official costing.

Economic impact by 2028-29

  • Jobs: Work incentives may weaken or strengthen depending on taper design and childcare constraints.
  • Wages: Household incomes rise for recipients; wages change only if labour supply shifts.
  • Prices: Extra demand can lift local prices slightly; national inflation effects should be small.
  • GDP / productivity: Long-run gains depend on child outcomes; near-term output effects are mostly demand-side.

Assessment

This is a real trade-off, not a free gain. Low-income families and renters benefit, while taxpayers through higher benefit spending bear most costs. Overall output depends on behaviour, capacity and pass-through.

Confidence: Medium-low. Higher on the policy target and fiscal channel; lower on behaviour, pass-through and economy-wide effects.

Main risks

  • Work incentives: Higher payments can weaken work incentives unless childcare and taper design are careful.
  • Take-up uncertainty: Costs rise if eligible households claim more than expected.
  • Poverty persistence: Cash support helps, but does not remove housing, childcare and health constraints.

Safeguards

  • Protect work incentives with taper analysis.
  • Publish take-up and poverty impacts.
  • Pair cash support with childcare and housing supply.

Active labour-market programmes

Employment programmes often perform better over the medium term than immediately, with design varying sharply.

Supports scepticism about quick employment savings.
