Many applicants don’t realise a SuDS report may be needed for planning validation — until it’s too late. You’ve prepared your documents, you’re ready to hit “submit,” and then you’re told a Sustainable Drainage Systems (SuDS) report is still required. In some cases, you may also be asked to complete a SuDS proforma before your application can move forward.
For most major developments, and increasingly for minor ones, local planning authorities and Lead Local Flood Authorities (LLFAs) expect surface water drainage to be addressed through a SuDS report before an application can be validated. Knowing what you need — and how quickly you can get it — helps you avoid costly delays.
How Long Does a SuDS Report Take to Complete?
The time required to prepare a SuDS report depends on several factors, including:
- The size of your development site
- Whether it is a minor or major planning application
- The specific requirements of your local planning authority
Major Planning Applications
For major applications, most local authorities require a detailed SuDS design at the planning stage. At Nimbus Engineering, we aim to complete SuDS reports and accompanying detailed SuDS designs within two weeks, depending on the complexity of the site and our current workload.
Minor Planning Applications
For smaller developments, a full design may not be required. In these cases, we can provide the SuDS report along with:
- A completed SuDS proforma
- An outline SuDS layout
- A site location plan
These can typically be delivered within 1 to 2 weeks.
