How to Calculate the Cost of a Housing Planning Application in the UK
If you’re planning a new home, a property extension, or a housing development, understanding the cost of your planning application is essential. In the UK, planning fees are set nationally, making it easier to calculate your costs once you know the type of application required. Whether you’re a homeowner or a property developer, knowing these costs upfront can help you budget efficiently.
1. Identify the Type of Planning Application
The planning application fee varies depending on your project:
Full Planning Permission: For new homes or major works.
Outline Planning Permission: To establish if your proposal is acceptable in principle.
Householder Planning Permission: For extensions or alterations to a single home.
Reserved Matters: For detailing aspects of an outline approval.
Other Consents: Such as listed building consent (often free).
2. Use the Planning Portal Fee Calculator
You can calculate your exact planning application fee online using the official Planning Portal Fee Calculator. Enter your project details such as the number of dwellings or site area to get an accurate cost.
3. Quick Fee Examples (England 2025)
New housing developments (up to 50 dwellings): £578 per dwelling.
51+ dwellings: £28,750 + £173 per dwelling, capped at £350,000.
Householder applications: £258.
Fees differ slightly in Scotland, Wales, and Northern Ireland, so always check local guidance.
