The 2026 planning rule changes: why your application now has to be right first time
A £548 fee with no free retry, appeals that cannot hear new evidence, and no committee to persuade. Three changes have quietly converged on the same point.
Since April 2026 a householder planning application costs £548, there is no free second attempt if it is refused, and — for applications made on or after 1 April 2026 — an appeal can no longer introduce evidence the council did not see. Your application file is now, for most homeowners, the only hearing you will ever get. The way to protect yourself is to make the first submission as strong as it can possibly be.
Three separate rule changes have converged on the same point, and most people applying for planning permission this year have not noticed. Each one, on its own, looks procedural. Put them together and they change what a planning application is: it used to be an opening position you could improve later. It is now the whole case.
1. Failure got expensive — and there is no free retry
From 1 April 2026, a householder application — extensions and alterations to your home — costs £548. A full application for a single new dwelling is £610. Fees rose 3.8% in line with inflation; the householder fee had been £528.
The number that matters more, though, is the one that disappeared. For decades a refused or withdrawn applicant could resubmit once within 12 months for free — the "free go". That exemption was abolished in December 2023, and the last transitional cases expired in December 2024. If your application is refused today, fixing it and resubmitting costs the full fee again. Refusal is no longer a setback that costs you time. It costs you £548, every time.
Around 15,000 householder applications were refused in England in the year to March 2026 — 151,900 decided, 90% granted. Every one of those refusals now carries a real price tag.
2. Appeals can no longer hear anything new
This is the change most people have not heard about. For planning applications made on or after 1 April 2026, most appeals against a refusal — including householder appeals — now go through an expedited written procedure, introduced by the Town and Country Planning (Appeals) (Written Representations Procedure) (England) (Amendment and Saving Provision) Regulations 2026.
Under that procedure, the appellant cannot submit evidence the council did not have when it made its decision. No new supporting statement. No new technical reports. No further representations from anyone during the appeal — including your neighbours. The inspector decides the appeal on the papers the council already saw, with only narrow exceptions for genuine changes in circumstances such as a policy change or a court judgment.
Under the old rules, a thin application could be rescued at appeal with a better-argued case. Under the new rules, the argument you make at application stage is the argument the inspector reads at appeal. If your Design & Access Statement never addressed the council’s amenity policy, nobody gets to address it later.
Appealing itself is still free, and the deadlines have not changed — 12 weeks for householder appeals. What changed is what an appeal is allowed to consider.
If your application was submitted before 1 April 2026, the older procedure still applies to it — you keep the full right to put a fresh, complete case to an inspector. That is a materially better position than anyone applying today, and it expires quietly as those cases work through. The free Route Check will tell you which side of the line your application falls on.
3. From this autumn, there is no committee to persuade either
Under the Planning and Infrastructure Act 2025, a national scheme of delegation comes into force on 31 October 2026. The regulations have now been made. From that date, householder applications — along with most minor applications — must be decided by planning officers rather than by councillors at committee.
For homeowners this closes the last informal escape route: the sympathetic committee hearing where a neighbour’s support or a councillor’s intervention could turn a recommendation around. An officer will decide your application on the file in front of them. Then, if you appeal, an inspector will decide it on that same file.
What this means: the written case is the whole case
Put the three together. The application file is read by an officer, with no committee. It costs £548 to submit, with no free retry. And if it is refused, it goes to an inspector who can only read what the officer read. Every route to a permission now runs through the quality of the documents you submit on day one.
That is why the Design & Access Statement — long treated as a box-ticking formality — has become the most important document most applicants will ever write. It is the one place you get to make the case: how the design responds to the street, why there is no harm to a neighbour’s privacy or light, how the scheme answers the exact policies your council’s officers will assess it against. Generic statements — "the proposal is in keeping with the area" — are precisely what refusals are made of, and there is no longer a second chance to be specific.
Getting it right first time
The pattern across refusals is consistent. Applications fail on design in context, on neighbour amenity, and on overdevelopment — and each is answerable before submission, with specifics tied to the right local plan policy. That means knowing which policies your council will apply, quoting them accurately, and putting the numbers on the page: separation distances, plot coverage, retained garden.
Our section-by-section guide to writing a Design & Access Statement covers how to do that, and the permitted development guide covers the cases where you may not need to apply at all.
Frequently asked questions
Can I still appeal a refusal?
Yes, and appealing is still free — householder appeals must be lodged within 12 weeks. But for applications made on or after 1 April 2026, the appeal is decided on the evidence that was before the council. You cannot add new reports, statements or arguments, and neither can anyone else.
If I am refused, can I just apply again?
Yes — but you pay the full fee again. The "free go" resubmission was abolished in December 2023 and fully phased out by December 2024. A refused householder application costs another £548 to resubmit.
Do these appeal rules apply to my existing application?
The new restrictions apply to appeals on applications made on or after 1 April 2026. If your application was submitted before that date, the older appeal procedure still applies to it.
Will my application still go to a planning committee?
From 31 October 2026, householder and most minor applications must be decided by planning officers under the national scheme of delegation. Decisions are made on the written file.
What should my Design and Access Statement actually include?
The specifics an officer needs in order to say yes: the existing context, the design rationale, the numbers on neighbour amenity such as separation distances, window positions and levels, and direct engagement with your council’s adopted policies, cited accurately rather than paraphrased.

Before you spend £548, find out if you even need permission
Many extensions are permitted development and need no application at all. The Permitted Development check is free and takes about two minutes — and with a £548 fee at stake it is worth knowing before you spend anything. If you do need to apply, Buildwise writes the Design & Access Statement, cited to your own council’s adopted policies.
