England (FRA)
In England a Flood Risk Assessment may be required to obtain a successful planning application. It is common that the planning authority would recommend that an assessment be undertaken during the planning process.
You will require an FRA if your site is within or partially within Flood Zone 2 or 3. Sites in Flood Zone 1 that are smaller than 1ha typically do not require a report unless they are considered to have ‘critical drainage problems’. An FRA may also be required for a ‘change of use’ to an existing site. From commercial to residential for example.

Wales (FCA)
In Wales a Flood Consequence Assessment may be required to obtain a successful planning application. It is common that an FCA should accompany a planning submission. It is vital that the FCA is written with respect to Technical Advice Note 15 (TAN15).
Natural Resources Wales have published Development Advice Mapping. The designation given to your site will have a big impact on the viability of your development.

FAQs
-
You should expect to receive your report 10 working days after receipt of supporting information
-
Your property could be at risk of flooding even if it has never flooded in the past. If your property is deemed to be in flood zone 2 or 3 then you will likely be required to submit an FRA.
-
In short, no. A flood risk assessment needs to be bespoke to your planning submission. The flood zones and suitability that your property may have to a neighbours could differ. We recommend that you have your own report completed.
-
Potentially. You will require a flood risk assessment should your site be identified as having ‘critical drainage problems’ by the EA, or your property is changing use to a greater vulnerability class. Such as office buildings to residential accommodation, or your development site is greater than 1ha. Should your site not fall into any of these categories, by definition you are not required to produce an FRA. We experience smoother planning applications when an assessment is undertaken anyway, to reinforce the applications viability. This can also save time in the planning phase.
