What Our Customer Says
Understanding Flood Risk in Kensington and Chelsea
Flood risk assessment in Kensington and Chelsea reflects its West London location along the Thames, where tidal influences combine with surface water pressures from densely built streets and historic urban form. The borough includes major heritage assets, high-value residential zones and critical transport corridors, all of which require careful consideration of drainage capacity and residual risks behind existing river defences. Limited space for surface water storage increases the need for high-quality, site-specific flood solutions.
When do you need a Flood Risk Assessment in Kensington and Chelsea?
In Kensington and Chelsea, a Flood Risk Assessment may be required where a planning submission must demonstrate that flood risk has been assessed properly and that the proposal remains appropriate for the site. For planning applications, the requirement can be triggered by flood zone location, sites within a Critical Drainage Area, large site thresholds, or proposals that introduce a more vulnerable form of development.
Common scenarios include:
- Development in Flood Zones 2 or 3: If your site in Kensington and Chelsea falls within Flood Zone 2 or Flood Zone 3, an FRA is typically required for the planning submission.
- Sites within a Critical Drainage Area: Even outside higher flood zones, sites within a designated Critical Drainage Area in Kensington and Chelsea will require an FRA, regardless of size.
- Sites over a certain size: Even in Flood Zone 1, sites in Kensington and Chelsea that are 1 hectare (10,000m²) or larger can still require an FRA for the planning application.
- Change of use: An FRA may be needed where a change of use introduces residential accommodation or another more vulnerable development type.
- Basement extensions: Basement works are a particular trigger in Kensington and Chelsea, where below-ground development must address drainage, groundwater behaviour, sewer flood resilience, and compliance with the Council's Basements SPD.
