Local planning authorities (LPAs) in England must now notify Housing Secretary Steve Reed before they reject planning applications for residential schemes of 150 homes or more. The rule takes effect before 31 March 2026 through revisions to the National Planning Policy Framework (NPPF). This represents part of the government's broader effort to streamline planning for housing delivery.

The government has also announced funding to support housing delivery through the National Housing Delivery Fund, targeting additional homes via its Brownfield Housing Fund (funding for development on previously built-on land) programme.

What the Rule Changes

Before this rule, LPAs could reject major residential schemes without escalation to national government. Now, if an LPA intends to refuse a scheme of 150+ homes, it must inform the Housing Secretary first. The government has not published what happens after notification - whether Reed's office can intervene, call in the application, or must simply be consulted.

This sits within a broader policy shift toward streamlining planning for major housing. The NPPF revisions completed consultation in late 2025, so the changes are not brand new policy - but the specific threshold and notification requirement is the operative mechanic now live.

The rule applies to both speculative housebuilders and mixed-use developers with major residential components.

Who Is Affected and How

Any developer or builder with a planning application for 150+ homes at any stage must assume the LPA will flag it to national government if it moves toward refusal. This includes applications that are currently pending, in pre-application discussions, or in appeal.

For LPAs, the administrative burden is clear: maintain a record-keeping process and notification protocol. Non-compliance with notification is a process failure that could itself become grounds for judicial review (a legal challenge to a public body's decision in the High Court) or appeal.

For applicants, the implication is less certain. Does Housing Secretary notification mean:

- A delay while the office reviews?

- A call-in threshold (formal intervention)?

- A right of appeal to national government?

- A purely ceremonial consultation?

The legislation does not answer this. Your planning consultant should clarify with the relevant LPA what their notification process looks like in practice.

The Deadline and What to Do Now

The effective date is before 31 March 2026. The NPPF revisions are published, so LPAs have the tool they need to comply.

If you have a major residential application (150+ homes) currently in planning, you may wish to:

- Confirm with your LPA that they understand the new requirement

- Review your appeal strategy, since refusal now triggers government notification (which may or may not trigger intervention)

- Speak to your planning consultant about how this affects timelines and risk allocation

- Factor the possibility of government intervention into your commercial assumptions if you're in pre-application stage
