Planning Application Fees and Costs Explained
What does a planning application cost? Fees, pre-application charges, consultant costs, and how to avoid wasting money on applications.
Planning permission is a gatekeeper for many home improvement projects - and it comes with costs beyond the headline application fee. Understanding the full fee picture helps you budget accurately and avoid expensive mistakes.
Government Fees
These are set nationally and apply across England:
| Application Type | Fee (2026) |
|---|---|
| Householder application (extensions, alterations) | £258 |
| Lawful Development Certificate (existing use) | £120 |
| Lawful Development Certificate (proposed use) | £120 |

| Certificate of Lawfulness (existing) | £120 |
| Discharge of planning conditions | £43 per condition |
| Non-material amendment | £43 |

Free resubmission: If your application is refused or withdrawn, you can submit a revised application for the same site within 12 months free of charge. This only applies to the first resubmission. Apply through the Planning Portal.
Professional Costs
The application fee is the cheap part. Professional preparation costs significantly more:
Architect / Architectural Technologist
Your architect typically handles the entire planning process as part of their design service:
| Service | Cost |
|---|---|
| Design + planning drawings (included in design fee) | £2,000–£5,000 |
| Planning drawings only (if already designed) | £800–£2,000 |
| Design and Access Statement | Usually included |
| Planning application submission and management | Usually included |
| Responding to planning officer queries | Usually included |
Planning Consultant
A specialist planning consultant is valuable for:
- Contentious applications (neighbour objections expected)
- Planning appeals after refusal
- Applications in sensitive areas (conservation, Green Belt, AONB)
- Change of use applications (annexes, home businesses)
| Service | Cost |
|---|---|
| Planning statement for householder application | £500–£1,500 |
| Full planning management (application to decision) | £1,000–£3,000 |
| Pre-application representation | £300–£800 |
| Appeal preparation and submission | £1,500–£5,000 |
Specialist Reports
Some applications require specialist supporting documents:
| Report | Cost | When Required |
|---|---|---|
| Heritage Impact Assessment | £800–£2,000 | Listed buildings, conservation areas |
| Tree survey (BS 5837) | £400–£1,000 | Trees on or near the site |
| Ecology survey (bat, newt) | £300–£1,500 | Rural sites, near watercourses, old buildings |
| Flood Risk Assessment | £500–£1,500 | Sites in Flood Zone 2 or 3 |
| Daylight/sunlight assessment | £500–£1,500 | Neighbour light impact concerns |
| Contaminated land report | £500–£2,000 | Former industrial sites |
| Archaeological assessment | £500–£2,000 | Sites of archaeological interest |
| Drainage strategy | £300–£800 | Larger extensions, sustainable drainage |
Most householder extensions don't need these reports. Your architect or planning consultant will advise which are required.
Pre-Application Advice: The Best Money You'll Spend
Pre-application advice is an informal consultation with a planning officer before you submit a formal application. It's available from most councils via the Planning Portal.
What You Get
- An officer's opinion on whether your proposal is likely to be approved
- Advice on policy issues, design concerns, and neighbour impact
- Guidance on what to change to make the application acceptable
- Identification of any specialist reports needed
What It Costs
| Council Approach | Cost |
|---|---|
| Free written advice | £0 (some councils still offer this) |
| Written response (householder) | £50–£150 |
| Meeting with officer (householder) | £100–£250 |
| Written response + meeting | £150–£300 |
Why It's Worth It
Pre-application advice costs £50–£250. A refused application costs:
- £258 in fees (non-refundable)
- £2,000–£5,000 in architect/consultant time
- 8–16 weeks of delay
- Potential redesign costs
A 15-minute conversation with a planning officer can save you thousands. Always seek pre-application advice unless your extension clearly falls within permitted development.

Saving Money on Planning
1. Use Permitted Development First
Many extensions don't need planning permission at all under PD rights. Check whether your project fits within PD limits before paying for a planning application. A Lawful Development Certificate (£120) gives you legal proof.
2. Get Pre-Application Advice
Spending £50–£250 upfront dramatically reduces the risk of a £258+ refused application.
3. Design to Policy
Ask your architect to design within local plan policies from the start. An extension designed to be approved first time is cheaper than one that needs redesign after refusal.
4. Combine Applications
If you need both planning permission and Building Regulations approval, you can work on both simultaneously to reduce the overall timeline. Your architect can prepare both sets of drawings in parallel.
5. Avoid Unnecessary Reports
Not every application needs a tree survey or ecology assessment. Your architect or the planning officer (via pre-application) can confirm exactly which reports are required - don't commission reports speculatively.
Timeline: Planning Application to Start on Site
| Stage | Duration |
|---|---|
| Design and pre-application | 4–10 weeks |
| Prepare application and submit | 1–2 weeks |
| Council validation | 1–2 weeks |
| Consultation period | 3 weeks (minimum) |
| Decision | 8 weeks (statutory target) |
| Discharge conditions | 2–4 weeks |
| Total to approval | 10–20 weeks |
After approval, you still need Building Regulations (2–5 weeks), Party Wall notices (4–10 weeks if applicable), and builder quotes (2–4 weeks). Total from first sketch to builder on site: 6–12 months.
