Fees and charges
Every application must be accompanied by the appropriate fee. Full details of planning application charges are available at the Planning Portal.
Use the Planning Portal's Fee Calculator to calculate the fee for an application.
The fee regulations allow local authorities to charge a planning application fee where permitted development rights have been withdrawn. Such applications attract the appropriate fee for the application.

Flood Risk Assessments for minor extensions in Flood Zone 2 and 3
Please note: A minor extension is a householder or non-domestic extension with a floor space of no more than 250 square metres.
If any part of the proposed development will fall within a flood zone you may be required to submit a Flood Risk Assessment (FRA).
Find out what flood zone a location is, using the Flood map for planning on GOV.UK.
Flood Risk Assessment are required by paragraphs 167-175 (footnote 59) of the National Planning Policy Framework (NPPF) for works to properties within Flood Zones 2 and 3, or where the site area is greater than 1 hectare, or the site is at risk of flooding from any source.
For guidance on the content of FRAs, visit:
- Environment Agency - Pre-Application and Post Permission Advice
- Preparing a flood risk assessment: standing advice (GOV.UK)
For householder/minor applications in Flood Zones 2 and 3, please complete the Householder and Other minor extension in Flood Zones 2 and 3 form attached below and submit with your application.
Biodiversity net gain
From 12 February 2024 developers in England are required to deliver 10% biodiversity net gain (BNG) when building new housing, industrial or commercial developments. This will apply to new planning applications, rather than existing applications.
BNG is measured in biodiversity units calculated through the statutory metric tool. This calculates how many units a habitat contains before development, to then calculate how many biodiversity units are needed to provide at least 10% BNG. The statutory biodiversity metric considers the size, quality, location, and type of habitat.
BNG can be achieved through on-site units, off-site units, or through statutory biodiversity credits. These credits will be available as a last resort from the government, to prevent delays in the planning system.
It is also important that BNG provides lasting benefits for the environment. Significant on-site and all off-site gains will need a legal agreement with a responsible body or local authority to monitor the habitat improvements over the 30-year period.
As BNG is implemented on 12 February 2024 it will apply to applications for major developments only and will be implemented for small sites (between 1 and 9 dwellings) from 2 April 2024. Roll-out of BNG for Nationally Significant Infrastructure Projects is expected in late 2025.
Further information on BNG can be found on GOV.UK and on the Planning Portal.
BNG Exempt developments
Some developments are exempt from the BNG requirements. These include householder developments, small-scale self-build and custom-build housing, permitted development, and proposals where the existing on-site habitat (to be impacted by the development) is ‘de-minimis’ (defined as below 25sqm of area habitat or 5 metres of linear habitat, for example watercourses, trees, hedgerows).
If you are submitting an application which you consider to be exempt from BNG, then this must be justified in the planning application. If your application is for Self/Custom Build, then please also complete the Self Build/Custom Build BNG exemption form attached below and submit with your planning application.
Publicity of planning applications
Once a planning application is registered, all information, apart from signatures, personal email addresses and personal telephone numbers, will be made publicly available on our Planning Application search pages.
Individuals and organisations offering their services may contact you. The Council does not endorse or approve any builders, surveyors, trades persons or other supplier, and advises householders to obtain quotes/references and check the legitimacy of any contractor who contacts them before making payment.
