National Planning Policy Framework consultation and next phase of planning reform

18 March 2026

On 16 December 2025, the government set out the next phase of their planning reform agenda, including a rewrite of the National Planning Policy Framework (NPPF) which will:

  • Introduce a permanent presumption in favour of suitably located development, along with preferential treatment for developments which support local economies.
  • Support higher density developments in sustainable locations. Making it easier for SME builders to build to a higher density.
  • Support the development of small and medium sites, including a new medium site category (10-49 homes).
  • Implement a default "yes" to building homes around train stations.
  • Improve the diverse mix of housing, including rural affordable homes and accessible homes for older and disabled people.
  • Streamline Biodiversity Net Gain requirements and encourage new builds to have nature-friendly features (e.g., swift bricks).

Steve Reed, Secretary of State for Housing, Communities and Local Government, has written to planning and housing stakeholders setting out these proposals.

We responded to the consultation on behalf of the sector and members can read a tis and the full briefing on the proposed changes below.

Our response

We welcome the Government’s National Planning Policy Framework reforms, particularly measures to support SMEs, increase densities, and deliver a broader mix of homes that reflect local needs, including for older people and rural communities.

  • Removing the requirement for direct delivery of S106 homes on medium sites risks weakening these reforms. Delays in the current cash-in-lieu system, where funds often go unspent and are ultimately returned to developers, would slow the pace of social and affordable housing development.
  • Our research shows that over one in ten S106 homes purchased by our members are on medium sites; for small and medium housing associations, this rises to one in four. Almost 10,000 affordable homes delivered nationally over the past three years wouldn’t exist if developers hadn’t been required to build them.
  • In exceptional cases, where delivering affordable homes on-site is genuinely unviable, cash-in-lieu contributions must be swiftly converted into new affordable housing delivery by local authorities or Registered Providers. Where funds remain unspent within a set timeframe, they should be transferred to Homes England or the GLA to support grant-funded local delivery.
  • Effective S106 delivery depends on early and consistent engagement between developers and housing associations and strong customer service throughout development and aftercare. Our research shows that when developers engage with housing associations early, they purchase twice as many S106 homes. DM1 should therefore explicitly name Registered Providers as bodies to engage at the pre-application stage.
  • We also welcome the inclusion of a clearer policy on Rural Exception Sites (RES); but without a dedicated Permission in Principle (PiP), delays and risks will persist – particularly for smaller providers. We therefore recommend a bespoke RES PiP to streamline approvals and support stronger rural delivery.
