New Planning Appeals Procedure to come into force on April 1st and it’s no April Fool!

9 March 2026

The new planning appeal process, effective from April 1st 2026, introduces changes aimed at streamlining the appeal process whilst also ensuring that applications are comprehensive and well-prepared from the outset. The Government’s objective is to deliver a faster, more efficient planning appeals process benefitting developers, local authorities and communities alike.”

Date of implementation:

For applications submitted before 1^st April 2026

Even if your appeal happens after April 2026, you will follow the old procedures. The date that matters is when you submitted your application to the local authority, not when you appeal.

For applications submitted after 1^st April 2026

The new streamlined process applies – so make sure your application is comprehensive before submission.

What are the differences?

Whilst there are a few exceptions to the rule, the following will apply:

• Appeals will be decided primarily on the information submitted with the original planning application.
• In most cases, new or additional evidence will not be accepted at appeal stage, unless it falls within tightly defined exceptions.
• Applicants are expected to resolve technical matters and submit full supporting evidence before an application is determined by the local planning authority.
• Interested parties such as neighbours will not be able to submit further comments at appeal.

The revised procedures are designed to increase the proportion of appeals dealt with through the written representations procedure, which is the simplest and quickest appeal route.

Clearer roles for interested parties

• Interested parties can continue to make representations at the application stage but not at appeal stage;
• Inspectors will rely on representations submitted to the local planning authority when determining the appeal.

Implications

The new procedures have important implications:

• Front‑loaded applications are essential – incomplete or under‑supported applications are far less likely to succeed at appeal;
• Early engagement with local planning authorities and consultees is more important than ever; and
• Appeal strategies will need to be carefully considered from the outset of the planning application process.
