Consultancy

WHS is a small, specialist team with huge experience.
Located around the UK, we bring local knowledge and personal service to every project. Whichever part of the water cycle matters to you, WHS scientists and engineers have it covered.

Software

WHS software sets the standard. Whether it’s for floods or low flows, WHS provides the tools regulators require and you can rely on. Coupled with openly published online technical guidance and supporting science reports, with a range of training options.

News Feature

Flooding affects 6.9 million UK homes—but not equally. Socio-economically disadvantaged communities often lack awareness, resources, and support to prepare or recover.

Key improvements needed include clearer local messaging, targeted funding, simplified grants, and better protections for renters and social housing.

Product Feature

We’re really pleased to announce a strategic collaboration with Jacobs for enhanced integration between Flood Modeller, ReFH2 and WINFAP.

As part of this collaboration, Jacobs will become the exclusive reseller of a new variant of WHS’ WINFAP and ReFH2 solutions with network and cloud-based licensing options.

Flow Report

The Qube Flow Estimation Service is a cost-effective alternative to buying our LowFlows 2 software to get river flow estimates. All it takes is an email with your request, your target location and a map. Leave the rest to us!
