Services
Flood Risk Assessments
We provide detailed Flood Risk Assessments (FRAs) for residential, commercial, and heritage sites across the UK. Our Director personally conducts site-specific evaluations using 25+ years of hydrological expertise. Reports incorporate Environment Agency standards, surface water run-off calculations, and mitigation strategies tailored to planning requirements and local flood risks.
Sustainable Drainage Design
Our sustainable drainage systems balance environmental impact with functional requirements for new developments. We design compliant solutions meeting Code for Sustainable Homes Sur1/Sur2 standards, focusing on recycled materials and long-term maintenance efficiency. Projects range from private estates to multi-use public spaces requiring critical drainage area reviews.
Highway Design
We deliver public and private highway design services from concept to construction supervision. Expertise covers public highways, private drives, and commercial estate access solutions. Our approach integrates safety standards with cost-effective materials selection, serving contractors, developers, and local authorities across diverse project scales.
Sewerage Network Design
Our sewerage design services combine technical precision with practical implementation considerations. We create strategic drainage networks for commercial developments and residential schemes, optimising existing infrastructure while addressing surface water and clean water management challenges. Former Thames Water engineering expertise informs all system designs.
Flood Mitigation
We develop comprehensive flood mitigation strategies for existing properties and new developments. Solutions include critical drainage area reviews, retention systems, and infrastructure upgrades. Recent projects demonstrate success in securing planning approval for flood-prone sites like the Abingdon Tennis Club extension through innovative engineering interventions.

Report
We instructed Wilsham Consulting to conduct a flood risk survey of a residential property. Stephen Gibson was a pleasure to deal with, providing valuable and professional advice. He was able to complete the work at pace and provided exactly the insight we were looking for to a very high standard. Stephen also worked in a flexible manner, answering our queries over email, on the phone and in his final report. It was pleasure working with Wilsham Consulting.

Report
I cannot recommend Wilsham Consulting highly enough. After coming on board to assist with a particularly complicated planning application involving flood zones, Stephen became a vital link between both the Environment Agency and the Local Authority and with his expert knowledge and advice the application was granted. An extremely impressive service all round and always available to answer questions, no matter how complicated.
