Fees where an application covers more than one category

A planning fee that is a pound short makes the application invalid, and an invalid application has no determination period, no target date and no appeal against non-determination. On a mixed scheme with houses, a commercial unit and a change of use in the same red line, working out the right number takes longer than most agents allow, because the fee is not simply the sum of the parts.

The rules are all in one statutory instrument, and the fastest way to get this right is to read it rather than to trust a calculator.

Where the rules actually live

Fees for applications in England are set by the Town and Country Planning (Fees for Applications, Deemed Applications, Requests and Site Visits) (England) Regulations 2012, as amended. The structure matters more than the figures.

Schedule 1 Part 2 contains the numbered categories of development, each with its own basis of calculation. Erection of dwellinghouses is charged per dwelling with a banded cap. Erection of other buildings is charged by gross floor space created, in bands. Outline applications are charged by site area. Changes of use, advertisements, telecommunications, agricultural buildings, glasshouses, plant and machinery, car parks and waste operations each have their own line.

Schedule 1 Part 1 contains the general provisions, and this is the part people skip. It deals with what happens when a proposal falls into more than one category, with applications submitted to more than one authority, with alternative applications, and with the concessions.

Fees were uplifted in December 2023 and are subject to annual indexation, so every figure changes. Never quote a fee from an old file or an old article. Check the current schedule.

Work out each category first

Before touching the combination rules, itemise the development.

1. List every element of the proposal separately: dwellings, non-residential floorspace, changes of use, plant, hardstanding, advertisements.
2. Identify which numbered category in Part 2 each element falls into. Do this by reading the category descriptions rather than by intuition, because several of them overlap.
3. Establish the measurement basis each category uses, and measure it the way the regulations define it, not the way the client's schedule of areas presents it.
4. Calculate each element on its own.
5. Only then apply the general provisions in Part 1.

Step three causes more errors than the rest combined. Floor space, site area and dwelling counts are all defined terms, and a gross internal area taken from a marketing pack is the wrong number.

When a scheme spans more than one category

Part 1 of Schedule 1 sets out how a proposal falling within two or more categories is charged, and it is not always additive. Read the provision, apply it to your itemised list, and write down the reasoning.

Then send that reasoning to the council. A short email to the validation team, setting out each element, the category you have applied, the measurement and the resulting figure, does two things. It gets you an answer before submission, and it creates a record if the fee is later disputed.

Mixed schemes have three recurring traps.

The first is treating an ancillary element as a separate category when it forms part of a single operation, or the reverse. The second is a change of use that also involves building works, where both the change and the works may need to be accounted for. The third is a scheme where part of the site is already in the proposed use, so the floorspace or unit count driving the fee is smaller than the headline scheme suggests.

Where the answer is unclear, the council's view is the one that determines validation, and it is quicker to accept a slightly higher figure than to argue about it and lose four weeks at registration.

Alternative applications and cross-boundary sites

Two situations in Part 1 are worth knowing before you need them.

Alternative applications, meaning two or more applications for different schemes on the same site, submitted by the same applicant at the same time, are charged under a specific provision rather than as two independent applications. If you are testing two options in parallel, check that provision first, because the saving is real.

Sites straddling the boundary between two local planning authorities are also dealt with expressly. Each authority receives an application, and the regulations govern how the fee is apportioned. Agree the split with both validation teams in writing before you submit, since the two authorities will not necessarily reach the same view unprompted.

Illustrative example: an application for 9 dwellings and a small retail unit on a site that also includes a change of use of an existing barn. The agent calculated a single dwelling-based fee. The council itemised three elements, applied the Part 1 provision, and returned the application as invalid. Six weeks were lost, and the fee finally paid was the number a fifteen minute reading of Schedule 1 would have produced.

Concessions, exemptions and refunds

Several provisions reduce or remove the fee, and they are easy to miss.

• Applications made solely for the purpose of works to improve access for disabled people attract no fee.
• Listed building consent and conservation area consent carry no fee, which surprises people who assume the heritage route is more expensive.
• A lawful development certificate for an existing use is charged at the full rate for the equivalent application, while a certificate for proposed development is charged at a reduced rate. Check which limb you are using.
• The regulations contain a concession allowing a further application in defined circumstances without a further fee, subject to time limits and conditions. That concession has been amended, so read the current text rather than relying on how it used to work.
• Where the authority fails to determine an application within the period set by the regulations, a refund of the fee may be due. The trigger period and the exclusions are specific, so check them rather than assuming.

Discharge of conditions is charged per request rather than per condition, which is why bundling conditions into a single submission is the sensible habit.

Getting the number agreed before you submit

Use a fee calculator to get a first answer, then check it against Schedule 1 yourself. A calculator is a convenience, not the law, and it cannot see the ancillary element buried in your description of development.

Then do three things. Confirm your calculation with the validation team in writing. Keep the confirmation with the submission. And put the fee, the category reasoning and the measurement basis into the covering letter, so the validation officer can check your working in two minutes instead of raising a query.

Where the scheme is complicated enough that the fee is uncertain, it is usually complicated enough to need a proper planning statement that describes each element clearly. A description of development that reads unambiguously is the single best defence against a validation dispute, and it is worth more attention than most applications give it.

This is general guidance rather than legal advice. Fees are indexed and the regulations are amended regularly, so check the current schedule with your local planning authority before relying on any figure.
