The planning guarantee and getting your fee refunded

The planning guarantee is the government commitment that a planning application should not sit undecided indefinitely, backed by a refund of the application fee where the council takes too long. For most applications the benchmark period is 26 weeks from validation, and where the authority has not issued a decision by then the fee becomes refundable. It is a modest sum against the cost of a stalled project, and claiming it is worth doing anyway, partly because the money is yours and partly because councils track the refunds.

The mechanism has been adjusted more than once, so check the current fee regulations before relying on the detail below.

What the guarantee promises

The commitment sits in the planning fee regulations rather than in policy, which matters because it gives it teeth. Where the conditions are met, the fee is repayable.

What it does not promise is a decision. The council remains free to take longer, and the refund is the only consequence within this mechanism. Officers will tell you frankly that a refund is not the outcome they want, because it shows up in the authority's own financial reporting, but a refund does not put your application in front of a committee any faster.

Nor does it stop the council determining the application afterwards. Unlike an appeal, claiming a refund leaves the application where it is.

The period and when it starts

The clock runs from the date the application is validated, not from the date it was submitted. An application held at validation for three weeks because a drawing was missing loses those three weeks from your side of the argument.

For most applications the benchmark is 26 weeks. Changes introduced alongside the 2023 fee uplift altered how the guarantee applies to some application types, including a shorter benchmark for householder applications, so check the current position rather than assuming a single figure covers everything.

Record the validation date when the acknowledgement arrives, and diarise the benchmark date at the same time. Councils are not obliged to remind you.

What an agreed extension of time does to it

This is the part that catches applicants, and it catches them because the request looks routine.

Where an extension of time has been agreed in writing, the guarantee is affected. The current regulations treat an agreed extension as changing the position, which in practice means an applicant who signs successive extensions can find they have contracted out of the refund without ever intending to.

Councils ask for extensions by email, often from the case officer, sometimes late on a Friday in the final week of the statutory period. The request is usually reasonable on its face. Before agreeing:

1. Ask what specifically remains outstanding and who is responsible for it.
2. Ask for a date by which the decision will issue, and put that date in the reply.
3. Agree one extension to a fixed date rather than an open ended period.
4. Note in the reply that you are not agreeing to any further extension without a committee date.
5. Keep the correspondence, because it is the evidence if the refund is later refused.

A planning performance agreement has a similar effect and is a deliberate bargain: a programme and a level of service in exchange for a fee and a longer timetable. That is a reasonable trade on a major scheme. It is not a trade worth making on a straightforward minor application.

Which application types it covers

The guarantee is directed at applications for planning permission. It does not extend to every request a council deals with.

Appeals to the Planning Inspectorate are outside it entirely, because no fee is charged for an appeal. Pre-application advice sits outside it as well, being a service the council prices itself. Applications withdrawn before determination fall away, and an application refused within the period has been determined, so the guarantee does not bite even if the decision was late in coming.

Where an application has been the subject of a section 106 agreement still under negotiation at the benchmark date, the position depends on whether the council has issued a decision. A resolution to grant subject to completion of the agreement is not a decision, so the clock keeps running, and that is the situation in which most refunds on major applications arise.

Requesting the refund

Some authorities process refunds automatically. Most do not.

Write to the planning department, addressed to the head of development management rather than to the case officer, setting out the application reference, the validation date, the benchmark date, the fact that no decision has been issued and the amount claimed. Attach the validation acknowledgement. Keep the letter to a page.

Expect the first response to raise one of three arguments: that an extension of time was agreed, that the application was invalid for part of the period, or that a decision was issued and not received. Each is answerable from your own records, which is why keeping the validation email and every extension exchange matters.

If the council declines and you think it is wrong, the escalation route is the authority's corporate complaints procedure and, after that, the Local Government and Social Care Ombudsman. That is a slow path for a modest sum, and most applicants take the view that the working relationship on the live application is worth more.

What it does not compensate

A fee refund is not damages.

It does not cover professional fees for the consultants whose reports have been sitting on the council's file, the holding costs on a site with borrowing against it, an expiring option agreement, the cost of re-running surveys that have gone out of date, or the loss of a build season. On a self-build plot, a delay running from spring into autumn can push the groundworks into winter, and that cost is many times the fee.

Nor does it compensate for the commercial effect of policy moving underneath you while the application waits, which is a real risk when a local plan is close to adoption or when national policy is being revised, as covered in what changes when the NPPF is re-issued.

Budget for delay rather than relying on a mechanism that returns the smallest number in the project. Supporting documents are one of the few costs you can control directly, and PlanScope pricing sets out the options: one free report, £50 per report, or £150 per month for unlimited reports on the Professional tier. PlanScope provides AI-assisted draft reports for planning applications, reports should be reviewed before submission, and we do not guarantee planning approval.

Using it alongside a non-determination appeal

The two mechanisms answer different problems and they interact awkwardly.

An appeal against non-determination becomes available once the statutory period expires, which is well before the guarantee benchmark. Lodging that appeal removes the council's power to determine the application, so the guarantee question changes shape: there is no longer a decision for the authority to make late.

In practice the sequence most applicants use is to press for a decision after the statutory period, agree at most one short extension on terms, and then choose between appealing and waiting. If you appeal, treat the fee as spent. If you wait, keep the benchmark date in the diary and claim the refund when it passes.

The one thing not to do is agree a rolling series of extensions while telling yourself the guarantee protects you. It probably does not, and each extension postpones the day the council has to act. Reform of this area continues, and the planning law updates timeline is the place to follow it.

This is general guidance, not legal advice. Check the current fee regulations and the position with your local planning authority or a qualified professional before relying on it.
