Planning validation requirements

We have published a new Local Requirements List which will set out new requirements for validating planning applications. 

You must include all the necessary information with your planning application. If you do not, your application cannot be validated, and may be returned to you. When an application is received, we give it a quick check and then prioritise the potentially valid applications.

Our local requirements list clarifies what information is required for applications of a particular type, scale or location. This list is in line with the Government’s national requirements. Our local list has been updated to reflect the requirements of the new London Plan (2021), matters around Fire Safety and a new local provision for a Community Audit on sites that propose redevelopment of non-residential spaces. 

We also have specific guidance for applications for windows and checklists which will help you submit a valid application.

On 1 October 2016 the Mayor of London applied new carbon standards to new residential and non-residential developments that might be applicable to your application.

On Friday, February 12 2024, it became mandatory for major development proposals to include biodiversity net gain. Find further information and guidance for your application.

Before applying for planning permission please ensure that you check whether your site falls within the BLE safeguarded zone.

In July 2025, the Lewisham Local Plan introduced a requirement for small sites (delivering between two and nine residential units) to provide financial contributions for affordable housing. We have prepared a specific guidance note and calculator (Excel document) to help you deal with this aspect of your application. 

If you have not received an acknowledgement letter or an invalid letter within two weeks of submitting your application, please contact our Business Support Team on 020 8314 7400 or email planning@lewisham.gov.uk. Please note that if your application is found to be invalid you will be given 21 days in which to make it valid. After that, it will be withdrawn.
