Reform UK Proposes Cutting Affordable-Housing Requirements on Brownfield Land to 5%
9/4/2026, 4:14:24 AM
Core Proposal
Reform UK’s “Planning Teal Paper,” released at the party’s annual conference, outlines a sweeping deregulation of the planning system for brownfield housing. The party would slash on-site affordable-housing requirements on brownfield schemes outside London, Manchester, Birmingham, Leeds and Bristol to 5 % for developments of 20 homes or more, or allow an off-site payment equivalent to 10 % of the required affordable units. It also proposes to scrape biodiversity net gain (BNG) requirements, the Community Infrastructure Levy, Section 106 payments, and most building-regulation standards for brownfield projects, retaining only those deemed “necessary,” such as fire safety.
Tax incentives would accompany the planning changes: landfill tax would be abolished, and new brownfield homes would be exempt from stamp duty and tax on rental income for ten years after completion. The party estimates these exemptions would cut tax receipts by just over £1 billion. It further proposes a decade-long exemption from capital gains tax for new brownfield homes, claiming this would have no effect on overall tax receipts.
Background & Context
The party frames the measures as a way to stimulate supply and prioritize brownfield development in urban areas. The policy document is being opened to a four-month public consultation, with responses due by 31 December; a finalized planning policy is slated for announcement the following year.
Data & Statistics
- Affordable-housing requirement on brownfield sites (outside the five major cities): 5 % on-site or 10 % off-site payment.
- Tax-receipt impact of stamp-duty and rental-income exemptions: ? £1 billion reduction (Reform UK claim).
- Capital-gains-tax exemption for new brownfield homes: no projected loss in receipts (party claim).
Official Statements & Responses
- David Jenrick, a Reform UK business spokesman, reiterated that affordable-housing requirements would be removed for brownfield developments outside major cities and that the tax incentives were intended to boost the economy despite the projected loss in receipts.
Timeline
- Consultation period: Open now, with a deadline for responses on 31 December.
- Final policy release: Planned for the year following the consultation.
Why It Matters
If implemented, the plan could accelerate brownfield housing construction by reducing regulatory and financial barriers. However, the drastic reduction in affordable-housing quotas may limit the supply of low-cost homes in many regions, potentially widening housing-affordability gaps. The fiscal measures, while aimed at spurring development, are projected to cut government tax revenue by over £1 billion, raising questions about the trade-off between short-term supply gains and long-term fiscal sustainability.
Conflicting Reports & Gaps
The sources provide no substantive external criticism or independent analysis of the proposals. Consequently, the potential social impact of reducing affordable-housing requirements and the accuracy of the party’s fiscal estimates remain unverified within the available reporting.
