Flood risk and water consulting
How we can help
Tell us about your site and what you are planning. We will review the available flood information with you and agree the work needed for your assessment or model.
Flood risk assessments
Assess flood sources, the effect of development and the measures needed to manage risk.
View serviceFlood modelling
Investigate flood levels, flow routes and the effect of design changes using hydraulic modelling.
View serviceFlood map challenges
Review mapped flood extents and prepare site-specific evidence where the mapping needs to be challenged.
View serviceFloodMetric screening
Review mapped flood constraints at an early stage and identify whether further assessment is needed.

Flood planning requirements differ across England, Scotland and Wales. Choose your country below for our advice and the relevant planning guidance.
England
Environment Agency guidance and the local planning authority’s flood evidence help establish what your application needs. Sites in Flood Zone 1 may still need assessment of other flood sources or future risk.

For a site in Scotland, we consider the Scottish planning framework, SEPA guidance and the council’s requirements together.

TAN15 and the Welsh Flood Map for Planning guide the planning assessment. NRW also provides a general Flood Risk Assessment Wales map, which serves a different purpose.

Common questions
Here are answers to common questions about this work. If you would like to discuss your own site, we can help you work out what is needed.
It may provide a useful starting point. We check its scope, date, data and relevance to the proposed development before advising what can be used and what needs updating.
A flood risk assessment considers flooding to and from the development, while a drainage strategy explains how rainwater runoff will be managed. We check whether your proposal needs both and make clear which work is included in your quote.
The site location, a short description of your plans and any comments from your planning authority are a useful starting point. If you have drawings or previous reports, share those too; we can help you work out what else is needed when we discuss the project.
After reviewing your plans and the information available, we provide a quote explaining the work, fee and expected timing. We also talk through any surveys, data requests or decisions from other organisations that may affect the programme.
