When planning costs fall due on a small housing scheme
Planning payments on a scheme of two to nine dwellings arrive in five clusters over roughly eighteen months. Knowing the order matters more than knowing the totals.
Planning costs on a scheme of under ten dwellings do not arrive as a single bill. They land in five clusters: design and survey work spent before you apply, the application fee at submission, condition discharge fees after permission, levy and obligation payments triggered by starting on site, and the utility and highway payments that follow. Eighteen months often separates the first cheque from the last. For a small developer, knowing when planning costs fall due matters more than knowing the totals, because the money rarely sits in one account waiting.
What follows assumes a full application for two to nine dwellings on a single site in England, with no Environmental Impact Assessment screening issue and no listed building. Adjust the sequence, not the logic, for outline permission or a phased build.
Costs before an application is made
Everything in this cluster is spent at risk. If the application fails, none of it comes back.
Pre-application advice usually comes first. Councils publish charges as bands by scheme size, and a minor residential band normally buys a written officer response and one meeting. Book it early enough that the answer can change the layout rather than confirm it.
Then the survey programme, which is the part that wrecks timetables. A preliminary ecological appraisal, the statutory biodiversity metric baseline, a tree survey to BS 5837:2012 where trees sit on or next to the site, a Flood Risk Assessment if any part of the site falls in Flood Zone 2 or 3 or the site is one hectare or more, and a ground investigation where the history suggests contamination. Several of these are season bound. Bat emergence surveys run May to September, great crested newt eDNA sampling only between 15 April and 30 June. Miss a window and you wait almost a year, which is a cash cost as well as a programme cost. The cost of missing an ecology window is usually borrowing cost rather than survey cost.
Design fees run alongside. Architects normally stage payments at RIBA work stages, so expect an invoice at the end of concept design and another when the application drawings are issued.
Costs at validation and determination
The application fee is payable at submission. The national fee regulations set the amounts, they are indexed annually each 1 April, and for new dwellings the fee is calculated per unit for schemes up to 50 dwellings. Use the current schedule rather than a figure you remember from a previous job. The Planning Portal adds its own service charge on applications submitted through it.
Validation is where small sums turn into weeks. If the council's local list asks for a document you have not supplied, the clock does not start. There is no fee for resubmitting a document, but there is a cost in holding professional fees and site finance open for another month.
During the eight week determination period for a minor application you may need extra work: a revised drainage detail, an amended plan after a highways comment, occasionally a fresh noise measurement. Budget a contingency of one further consultant instruction rather than none.
One concession is worth remembering. The fee regulations allow a single free resubmission within twelve months of a refusal or withdrawal, provided the application is for development of the same character and description on the same site. It applies once, and only to the fee.
Costs on discharge of conditions
A permission on a minor scheme commonly carries between eight and twenty conditions. Each request to discharge them attracts a fixed fee under the fee regulations, charged per request rather than per condition. Group conditions into one submission wherever the evidence is ready at the same time, because four separate requests cost four times as much as one covering all four conditions.
The professional work behind those requests is the larger number. A construction management plan, a tree protection method statement, a materials schedule with samples, a surface water drainage detail signed off by the lead local flood authority, an external lighting layout. Each of these is a short document, and each needs someone competent to put their name to it.
Pre-commencement conditions are the ones to attack first. Until they are discharged you cannot lawfully start, which means you cannot serve a commencement notice, which means the levy sequence below cannot begin.
Levy and obligation payments after a start
Community Infrastructure Levy money falls due after commencement, not at permission, and the paperwork order is unforgiving. The council issues a liability notice. Someone must assume liability in writing. A commencement notice must reach the authority before work starts. Only then does the demand notice set out what is payable and when, following the authority's published instalment policy.
Get the order wrong and the consequences are financial. Start without serving a commencement notice and the whole amount can become payable immediately, with instalment rights lost and a surcharge added. Self-builders have an exemption available, but it must be claimed and granted before commencement, and it is clawed back if the dwelling is not occupied as the applicant's sole or main residence for three years. Work through liability from the charging schedule before you exchange on the land, because the rate per square metre is indexed and the chargeable area includes garages.
Section 106 obligations on a small scheme are usually modest: a contribution towards open space or education, sometimes an affordable housing payment in lieu. Triggers are drafted into the deed, commonly on commencement or on occupation of a stated unit number. Monitoring fees are often payable when the agreement is completed, so before you start.
Utility and highway payments
Highway works come through a section 278 agreement with the local highway authority, and the cost is built from design check fees, a bond, inspection fees and a commuted sum for future maintenance. How a section 278 cost is built up explains why the quote is rarely the construction price alone. Where a new street is to be adopted, a section 38 agreement adds its own bond.
Electricity connection quotations from the distribution network operator expire, often within 90 days, so requesting one too early wastes the fee. Water and sewer connections under the Water Industry Act 1991 carry their own charges, and a foul sewer connection to a public sewer can require a formal agreement rather than a simple application.
Building control and warranty costs
Building control charges are separate from planning and are payable whether you use the local authority or an approved inspector. Full plans applications are charged in two parts, a plan check and an inspection charge, the second usually invoiced after the first inspection.
Lenders on a self-build almost always require a structural warranty or a professional consultant's certificate, and that premium is priced on the build cost, not the plot. Add the energy modelling needed to demonstrate Part L compliance and, on some dwellings, Part O overheating.
Constructing a simple spend profile
Put the stages on one page with the month each payment falls, then overlay your funding drawdowns. The point is to spot the months where two clusters collide.
| Stage | What falls due | Typical timing |
|---|---|---|
| Pre-application | Council fee band, initial design | 4 to 6 months before submission |
| Survey programme | Ecology, trees, flood risk, ground | 1 to 5 months before submission |
| Submission | Application fee, portal service charge | Month 0 |
| Determination | Amended plans, extra technical notes | Months 1 to 3 |
| Conditions | Discharge fees, method statements | Months 3 to 6 after decision |
| Commencement | Levy instalment one, monitoring fees | On or shortly after start |
| Infrastructure | Section 278, bonds, connections | Start to completion |
| Build | Building control, warranty | Across construction |
An illustrative example: five detached houses on a 0.4 hectare paddock, submitted in March. Ecology work has to be commissioned the previous May to catch the bat season, so the first substantial spend sits ten months ahead of submission. The application fee lands in March, condition discharge fees in August, and the first levy instalment in the November after that. Two peaks, roughly nine months apart, with a quiet stretch between them that is easy to mistake for the end of the spending.
Report drafting is the one cluster you can compress. PlanScope produces AI-assisted drafts of the narrative documents from your site data and answers, which you then edit and send for professional review where a report needs a competent author. See PlanScope pricing: one free report, £50 per report, or Professional for unlimited reports.
This is general guidance, not legal advice. Fee amounts, levy rates and instalment policies change, so check the current schedules with your local planning authority before you commit to a cash flow. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval.
Frequently asked questions
When is the Community Infrastructure Levy actually payable?
After commencement, not at permission. The council issues a liability notice, someone assumes liability in writing, and a commencement notice must arrive before work starts. Only then does a demand notice set out the instalments under the authority's published policy. Starting without serving the commencement notice can make the whole sum payable at once, with a surcharge.
Can I get the application fee back if permission is refused?
No. The fee buys determination, not permission. The fee regulations do allow one free resubmission within twelve months of a refusal or withdrawal, for development of the same character and description on the same site. That concession covers the fee only, so you still pay for any revised drawings or technical notes.
Is the condition discharge fee charged per condition?
It is charged per request. That is why grouping several conditions into one submission costs less than sending them separately as each piece of evidence arrives. The saving is on the fee, so weigh it against the delay of waiting for the slowest document before you submit anything at all.
How early should I commission ecology surveys?
Work backwards from the seasonal windows rather than from your submission date. Bat emergence surveys run May to September and newt eDNA sampling only between 15 April and 30 June. On a spring submission that usually means instructing an ecologist the previous spring, which puts your first large payment almost a year ahead of the application.
Do small sites pay section 106 monitoring fees?
Often yes, where an agreement is needed at all. Monitoring fees are commonly payable on completion of the deed rather than on commencement, so the money leaves before you start on site. Check the drafted trigger in the deed itself, because wording varies between authorities and the sum is rarely negotiable late.
