What does the NPPF consultation mean for SME developers?

The government’s proposed changes to the National Planning Policy Framework (NPPF) could create faster, more predictable planning routes that help SME developers bring forward new homes more easily.

The consultation, which closes on 10 March 2026, sets out major reforms aimed at boosting housing delivery and economic growth, from strengthening the presumption in favour of development and encouraging higher density development in suitable locations such as near train stations to limiting the circumstances where a requirement for more than a 10% biodiversity net gain can be required.

For SME developers, many of the proposed reforms respond to long-standing challenges, including slow validation, inconsistent information requirements, limited access to smaller sites and delays caused by statutory consultees.

Clearer principle of development

The consultation introduces an explicit principle of development within settlements (policy S4) and a controlled but positive approach outside settlements (policy S5).

Combined with policy L1, which promotes more effective use of land in urban and suburban areas through infill and upward extensions, these proposals should reduce uncertainty for policy-compliant SME schemes. They also support the types of infill and brownfield sites SMEs often specialise in delivering.

More small and medium-sized site allocations

The proposals include a ‘medium development’ category covering 10 to 49 homes or up to 2.5 hectares. Local plans would need to allocate 10% of housing on 1 to 2.5-hectare sites, in addition to 10% on sites of one hectare or less.

Increasing the number of small and medium allocations should help SMEs secure planning permission more quickly.

Grey belt opportunities

The amended definition of grey belt land would bring more land within that classification by removing the impact of a proposed development on various land designations (habitat sites, national landscapes, heritage assets etc) when assessing whether a site is grey belt or not.

However, unless wider issues around affordable housing delivery are addressed, the proposed requirement for 50% affordable housing provision on major grey belt development sites may continue to affect viability and slow housing delivery.

Standardised information requirements for planning applications

New national decision-making policies (DM1–DM3) would standardise the information required for planning applications. This should ease the validation burden for SME developers, reduce unnecessary variation between local planning authorities and help speed up the initial stages of the process.

Whilst these policies appear minor, consistency across the Country should help developers manage costs and avoid delays.

Greater certainty on developer contributions

Policy PM12 aims to set clear expectations for developer contributions at the plan-making stage. This would help SMEs make realistic offers for sites and give landowners a clearer understanding of what price can reasonably be achieved, reducing later viability disputes that often delay delivery.

Faster decisions through targeted consultation

Under the proposals, statutory and internal consultees would only be consulted where necessary. Decisions would not be delayed if consultees miss deadlines unless their input is essential to approving the application. This is intended to reduce one of the main causes of delay faced by SMEs, helping them manage costs and deliver sites more quickly.

Standardised conditions and obligations

The use of standardised planning conditions and obligations is intended to streamline the planning application process and speed up granting consent. However, local planning authorities should avoid a one-size-fits-all approach, which could create new viability issues instead of supporting timely delivery.

Conclusion

Overall, the proposed NPPF reforms aim to create a more consistent and predictable planning system. Many of the changes are welcome for SME developers, who would benefits from a stronger presumption in favour of development, more small and medium‑sized site allocations, streamlined validation, targeted consultation and greater certainty around contributions.

If implemented carefully, the reforms could remove several long‑standing barriers and help SMEs deliver new homes more quickly.
