The planning guarantee and refunds for late decisions

The planning guarantee fee refund is the government's commitment that no application should take more than 26 weeks to decide, and that where it does the applicant gets the application fee back. It is a modest sum against the cost of a delayed self-build, and it is not an alternative to getting a decision. Treat it as a deadline the authority is working to rather than as compensation, and the useful part becomes clear: the 26 week point is when a stalled application starts costing the council something.

What the guarantee promises

The mechanism sits in the Town and Country Planning (Fees for Applications, Deemed Applications, Requests and Site Visits) (England) Regulations 2012, which require a refund of the fee where the authority has not determined the application within the prescribed period.

The guarantee is a policy commitment given effect through those Regulations. It does not make the permission deemed granted, it does not oblige the council to decide the application in your favour, and it does not stop the council continuing to determine it after the refund.

The fees regulations have been amended repeatedly, including the 2023 uplift and the move to annual indexation from April 2025, so check the current consolidated version on legislation.gov.uk for the categories the refund provision applies to before you rely on it for a particular application.

The period after which a refund is due

Twenty-six weeks runs from the date the valid application was received, not from the date you submitted it and not from the date the council got round to registering it.

That distinction matters. An application returned as invalid for a missing document starts its clock again when the complete submission arrives, which is one of several reasons to get the validation requirements right first time.

The gap between the statutory period and the 26 week point is the practical problem. An application that should be decided in eight weeks can sit for 18 more before the refund bites, and nothing about the refund speeds it up.

Applications outside the guarantee

Three situations take an application out of it, and the first is the one that catches self-builders.

An agreed extension of time displaces the refund. Where you sign an extension, whether by email or on a formal agreement, the clock resets to the agreed date. Councils routinely ask for extensions as the statutory period expires, and the request often arrives with a friendly explanation about workload.

Second, an application that goes to appeal on non-determination is outside the refund provision, because the authority no longer has the application to decide.

Third, prior approval applications operate on deemed consent rather than refunds. If the authority fails to respond within the period set by the relevant class in the General Permitted Development Order, you get the development rather than the money.

The extension of time trap

Agreeing an extension is sometimes right. Where a consultee response is still outstanding for good reason, where you are mid-negotiation on a section 106, or where the alternative is a refusal drafted in haste, an extension buys a better decision.

It is wrong where the authority simply has not started. Agreeing a twelve week extension on an application nobody has read converts your deadline into theirs and costs you the only pressure point you have.

Ask for three things before agreeing. A named officer. A date by which the report will be drafted. And a short extension rather than an open-ended one, with a further extension available if progress is real. Our note on appealing non-determination, and whether to wait sets out when to stop extending altogether.

How to claim the refund

The duty to refund sits with the authority. In practice you will have to ask, because few councils operate an automatic process.

1. Diarise the 26 week date when the application is validated, from the validation date on the acknowledgement rather than from your submission date.
2. Check whether you have agreed any extension, including informal agreement by email, since that will have moved the date.
3. Write to the authority's planning support or technical team, quoting the application reference, the validation date and the regulation, and asking for the refund of the fee paid.
4. Copy the case officer and the planning manager, and ask in the same letter for a date for determination.
5. Keep the payment receipt and the card or bank reference, since the refund usually goes back to the payer rather than to the agent.
6. If nothing happens, escalate through the authority's corporate complaints procedure, and then to the Local Government and Social Care Ombudsman for maladministration.

The sum is the application fee, not your professional fees, not the cost of the supporting reports, and not any loss caused by the delay.

Whether a refund helps the programme

Honestly, not much on its own. The fee for a single dwelling is a small fraction of what a six-month delay costs a self-builder in finance, rising build costs and a missed season for groundworks.

Where the refund helps is as a signal to the people who manage budgets. A council that is approaching 26 weeks on your application is approaching a reportable loss of income, and the planning manager cares about that more than the case officer does. A polite letter at week 22 asking whether the authority expects to determine the application before the guarantee period expires tends to produce a response that a chasing email at week 12 does not.

The other use is evidential. Where you later appeal, the chronology of the application, including the refund correspondence, supports an argument about delay and occasionally about costs.

Using the guarantee to apply pressure

Pair it with the two other pressure points rather than relying on it alone.

The first is the non-determination appeal, available once the statutory period has expired without a decision. It takes the application away from the council and puts it before an inspector, which is slower than a cooperative council and faster than an uncooperative one.

The second is the decision about whether to agree an extension at all. An applicant who has already said no once is treated differently from one who has agreed three extensions.

And keep the application clean. An application that was validated first time, with every document on the local list supplied and a Planning Statement that addresses the relevant policies, gives the authority nowhere to point when it explains the delay. Checking which fee exemptions and reductions apply is worth doing at the same time, because the self-build exemptions are easy to miss.
