Sustainable Drainage Approving Body (SAB)
From 7 January 2019 any developments with a construction area of 100 square metres or more, or of more than one dwelling, will require the prior approval of the Sustainable Drainage Approving Body (SAB) to a system of sustainable drainage.
This is mandatory and projects cannot lawfully commence without this approval.
SAB approval is separate to planning permission, you must make separate applications for each.
You are advised to obtain early professional drainage advice if your project meets or exceeds the above thresholds.
- construction areas less than 100 sqm
- existing sites with planning permission prior to 7 January 2019
- sites for which a valid planning application has been received by 7 January 2019
- sites for which outline permission has been granted by 7 January 2019 and an associated reserved matters submission is made by 7 January 2020
1. Check if planning permission is needed
New buildings, major alterations, enlargement of existing buildings and changes in use of buildings and land normally require planning permission but there are exceptions.

Permitted development describes building works that do not need planning permission and regulations are different in England and Wales.
Permitted development regulations are complex and you are advised to submit the householder preliminary enquiry form (pdf) with details of any proposed development before work starts.
Any advice given by the planning section represents an officer’s informal opinion based on the detail that you have provided and is not legally binding on the council.
You are strongly advised to apply for a Certificate of Lawfulness, a legally binding document confirming that planning permission is not required.
Before starting any works you are obliged to ensure that you have all necessary permissions as unauthorised development carried out without planning permission will be liable to enforcement action.
