Why a drafted report cannot work out your planning fee
Fees are set by an uprated statutory schedule and depend on measurements no supporting document contains. How to work one out and record it properly.
A drafted report cannot tell you what to pay the council, and it should not try. Planning fee calculation draft output is a category error: the fee depends on the application category, the measured quantum and whether a concession applies, and all three sit outside the text of any supporting document. The amounts themselves live in a statutory schedule that is uprated, which means any figure written into a document has a shelf life.
This is worth being clear about with clients, because an underpaid fee makes an application invalid and the determination clock does not start.
What the fee depends on
Three inputs, none of which appear in a planning statement.
The category of application. A householder application, a full application for one or more dwellings, an outline application, an application for approval of reserved matters, a prior approval under the General Permitted Development Order, a lawful development certificate, a section 73 variation, a section 96A non-material amendment, an application to discharge conditions and an advertisement consent are all charged differently. Listed building consent carries no fee at all.
The quantum. For residential development that is the number of dwellings. For other development it is usually the increase in gross floorspace, or for outline applications the site area. These are measurements taken from the drawings, and they have to be measured consistently with how the regulations define them.
Whether a concession applies. The most useful is the one free further application on the same site within a defined period after a refusal or withdrawal, where the development is of the same character and description.
Where the figures are set and indexed
Fees are set by the Town and Country Planning (Fees for Applications, Deemed Applications, Requests and Site Visits) (England) Regulations 2012 as amended. The schedule was uprated in December 2023, and provision was made for annual indexation from April, which means the figure for the same application changes between financial years.
That indexation is the reason to look the fee up at submission rather than at design stage. A fee quoted to a client in February for a submission in May can be wrong by the time the cheque is written, and the council will simply treat the application as invalid until the balance arrives.
Keep the regulations themselves in view rather than a secondary summary. Where a council's own guidance and the regulations appear to differ, the regulations govern, though in practice a conversation with the validation team resolves it faster than an argument.
Bands, concessions and the free resubmission
The structure is banded rather than linear. Residential fees are charged per dwelling up to a threshold, then at a different rate above it, subject to an overall maximum. Floorspace-based fees are charged in defined increments of gross floorspace, again with a different rate above a threshold and a cap. Outline applications are charged by site area in increments.
The practical consequences of banding are easy to miss.
- A scheme that crosses a band boundary by one unit or a few square metres can cost noticeably more than the one below it.
- Where there is no increase in floorspace, a floorspace-based fee may fall to a flat minimum rather than to nothing.
- The free further application concession is a single use and is tied to the character and description of the development, so a redesigned scheme may not qualify.
- Concurrent applications for alternative schemes by the same applicant on the same site can attract a reduced fee, which is worth checking before submitting two at full price.
Exemptions exist too, including works to improve access for a disabled person. They are specific and narrow, so read the provision rather than relying on a general impression that the work is charitable or beneficial.
Multiple applications on one site
Each application attracts its own fee, and the fee is not reduced because the drawings are shared. On a typical minor scheme a client can end up paying for a full application, then a discharge of conditions request, then a section 73 variation, then a further discharge request.
Discharge of conditions is charged per request rather than per condition, which is the single most useful piece of fee arithmetic on a live site. Grouping eight conditions into one request costs a fraction of submitting them one at a time, and the only reason to split them is where some details will be ready months before others.
Where a site is being phased, the fee position should be mapped at the outset alongside the obligations. Clients absorb a planned sequence of charges far better than an unplanned one.
| Application type | Usual basis of charge | Common slip |
|---|---|---|
| Householder | Flat fee | Assuming outbuildings are included in an extension application |
| Full, residential | Per dwelling, banded, with a cap | Counting flats and houses inconsistently |
| Full, other development | Per increment of additional gross floorspace | Measuring internal rather than gross area |
| Outline | Per increment of site area | Red line drawn larger than the development area |
| Discharge of conditions | Per request | Submitting conditions one at a time |
| Listed building consent | No fee | Forgetting the accompanying full application still carries one |
A worked floorspace band example
Here is the method, illustratively, without the figures.
A commercial unit is being extended. First, establish the category: a full application for development other than dwellings. Second, measure the increase in gross external floorspace from the proposed and existing plans, using the same convention for both. Third, convert that increase into the number of charging increments defined in the schedule, rounding as the regulations require. Fourth, read the rate for that band and check whether the quantum crosses the threshold where a different rate applies. Fifth, check for an applicable concession. Sixth, look the resulting figure up in the current schedule and record the date.
Every one of those six steps needs a measurement or a lookup that a supporting document does not contain. That is the honest reason a draft cannot produce the number.
Where the calculator lives
Use the fee calculator on the Planning Portal, and cross-check anything unusual against the Fees Regulations and the published guidance on fees. For a complex or phased scheme, email the council's validation team with the proposed category and quantum and ask them to confirm the fee before submission.
That email is worth more than the five minutes it takes. Validation teams are the people who will reject the application, and a written confirmation from them is the best protection against the most avoidable form of delay, which is also the theme of why planning applications are returned as invalid.
Keeping the record of the calculation
Record the category, the measured quantum, the band, the figure, the source and the date, and keep it with the submission file. Three reasons: the client will ask, the fee may be queried on validation, and if the scheme is refused you will need to know whether the free further application applies and when that window closes.
Where a report is drafted with AI assistance, the fee is one of the things a draft should leave blank rather than estimate. PlanScope drafts insert a flag where a site-specific fact is missing instead of inventing it, and a fee is exactly that kind of fact. Report credits shown in the PlanScope wizard are about report generation and have nothing to do with the council's application fee; PlanScope pricing covers the former only.
The division of labour here is the same one that applies throughout: a draft gives you the structure and the policy coverage, and you supply the measured, dated and checkable facts, which is the point made in what drafts get right about structure and wrong about evidence.
PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval.
Frequently asked questions
Why can an AI draft not calculate my planning fee?
Because the fee depends on the application category, a measured quantum taken from the drawings and whether a concession applies, none of which is in the document text. The amounts also sit in an indexed statutory schedule that changes between financial years, so any figure written into a report dates quickly.
Where are planning fees set?
In the Town and Country Planning (Fees for Applications, Deemed Applications, Requests and Site Visits) (England) Regulations 2012 as amended. The schedule was uprated in December 2023 with provision for annual indexation from April, so look the figure up at submission rather than at design stage.
How is the discharge of conditions fee charged?
Per request rather than per condition. Grouping several conditions into one submission costs a fraction of submitting them individually. The only reason to split is where some details will be ready months before others and you need an early approval to start work.
Is there a free resubmission after a refusal?
There is a single free further application on the same site within a defined period after a refusal or withdrawal, provided the development is of the same character and description. A substantially redesigned scheme may not qualify, so check the provision rather than assuming the concession applies.
What happens if I underpay?
The application is invalid and the determination period does not start. The council will ask for the balance, and the delay falls entirely on the applicant. Confirming the fee in writing with the validation team before submission is the simplest way to avoid it.
Do PlanScope credits relate to the council fee?
No. Report credits shown in the PlanScope wizard relate to generating draft reports and have nothing to do with the planning application fee payable to the local planning authority. The two are separate costs and should be presented separately to a client.
