Planning validation requirements

Planning validation requirements

On this page you can find information to help you submit a valid planning application.

You must include all the necessary information with your planning application. If you do not, your application cannot be validated. 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 recently been updated to include a new requirement under “general requirements for all plans”, which states that wherever possible, plans greater than A3 in size should not be submitted.

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.

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 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 After that, it will be withdrawn.

Planning fees are going up on 17 January 2018

From 17 January 2018, the Government will introduce a 20% increase in planning fees.

This includes:
  • fees for planning permission within conservation areas and properties
  • fees for planning permission where permitted development rights have been removed by condition
  • a fee of £402 per 0.1 hectare for permission in principle applications
  • a fee of £96 for prior approval applications to permitted development rights that were introduced in April 2015 and April 2017. These include the rights for the installation of solar PV equipment on non-domestic buildings, the erection of click-and-collect facilities within the land area of a shop, the temporary use of buildings or land for film-making purposes and the provision of temporary school buildings on vacant commercial land for state-funded schools.

If you submitted an application before 17 January but have not yet provided the correct fee, you will be charged the new, higher fee level in place at the time at which we contact you to provide the fee.
