Expand affordable homes funding

Policy baseline

Spending Review 2025 increased capital support for housing. More public grant can raise affordable supply but competes for construction capacity.

• Targets affordable and social rented homes.
• Grant cost depends on tenure and land prices.
• Housing-benefit offsets are slow and uncertain.

Core trade-offs

The direct beneficiaries are low-income renters and councils. The costs fall mainly on taxpayers and land-constrained areas. The main economic question is construction capacity may raise costs.

• Low-income renters and councils gain most directly.
• Costs fall mainly on taxpayers and land-constrained areas.
• Key risk: construction capacity may raise costs.

Fiscal impact by 2028-29

+GBP 2.5bn to +GBP 8.0bn. Central estimate: +GBP 4.0bn.

• 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: Construction jobs rise if planning, finance and skills constraints are resolved.
• Wages: Construction wages may rise in shortages; renters and buyers gain from greater supply.
• Prices: More supply should reduce price pressure; infrastructure costs may be partly passed on.
• GDP / productivity: Likely positive if homes are additional and located near productive labour markets.

Assessment

This is a real trade-off, not a free gain. Low-income renters and councils benefit, while taxpayers and land-constrained areas 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

• Build-out risk: Planning approval does not guarantee completions if demand, finance or infrastructure are weak.
• Infrastructure pressure: New homes need transport, schools, health and utilities funding.
• Local resistance: Legal and political constraints can delay delivery.

Safeguards

• Fund planning teams and infrastructure upfront.
• Track completions, not permissions.
• Target high-demand labour-market areas first.
