Flood Risk Assessment Pricing
Most Flood Risk Assessments start from £750, with the final cost depending on site size, flood zone classification, and the level of detail required by your local planning authority. For a full cost breakdown, see our Flood Risk Assessment Cost guide.
How Fast Can You Deliver?
Most Flood Risk Assessments are completed within 3–5 working days of instruction, depending on site complexity and how quickly the required information is available.
For time-sensitive planning applications, we also offer a 48-hour priority turnaround — without compromising on compliance or technical quality. Let us know your deadline when requesting your quote, and we’ll confirm what’s achievable for your project.
- Site size — larger sites (over 1 hectare) typically require more detailed modelling.
- Flood zone classification — Flood Zone 2 or 3 sites often need a more thorough assessment than Flood Zone 1.
- Planning stage — outline applications may need less detail than full/detailed applications.
- Change of use — a change to a more vulnerable use class (e.g. commercial to residential) can increase the scope required.
