We investigate how sites behave. Flooding, drainage performance, levels and constraints. That insight feeds directly into our work, whether for planning, design or resolving existing issues.

The FPS Environmental approach


Team of surveyors wearing FPS Environmental branded high visibility jackets and holding an ipad

Engineering that starts with understanding the site, and ends with places that work.

We support both new development and the investigation of existing sites where issues need to be properly understood.

A lot of engineering consultancies focus on design for planning.

We do that, but we also investigate existing sites.

That means understanding how and why flooding happens, how drainage actually performs, and what has changed over time.

We look at the reality on site, not just what drawings or guidance suggest.

That feeds directly into our work. Whether it is a drainage strategy for planning, a review of an existing system or a more detailed investigation, the approach is the same.

Understand the problem first. Then design properly.

The result is engineering that is proportionate, site specific and defensible.

Our work covers both investigation and design. That gives us a clear understanding of how sites behave and how to engineer them properly.

Working with homeowners, developers, asset owners, infrastructure providers and the public sector on both new developments and existing site issues, where flood risk, drainage and wider engineering constraints need a clear and deliverable strategy.

How we work


FPS Environmental consultant lifting manhole

Forensic engineering grounded in real conditions

At FPS Environmental, our starting point is always the site.

We review available data and, where needed, carry out site visits, drainage reviews and investigations.

We look at how water moves, how systems perform and where constraints exist.

From there, we develop solutions that meet planning requirements and reflect what is happening on the ground.

Levels, ground conditions, existing infrastructure and how the site has changed over time all matter.

This approach reduces risk and avoids over design. It also means our work stands up when it is challenged.

Client Testimonials

Here are some of our latest testimonials from satisfied customers. If you’d like to discuss your requirements further, please don’t hestitate to get in touch.

Mark and his colleagues have been excellent in helping us through a difficult flood recovery period. Their initial survey (carried out in the pouring rain) was thorough and critical to us when submitting the Application for a Flood Resistance grant from Gloucestershire County Council/DEFRA. Importantly, FPS respond swiftly and communicate well, answering questions and liaising with the local government departments proactively. In our experience, this is an operation you can trust.

Michael Constantine

Homeowner

We engaged FPS to conduct a survey of our property following a devastating flood during Storm Babet. The whole process was professionally handled from initial contact to receipt of the final, very detailed report. Questions arising from the report were quickly and fully answered and we are now in the process of implementing the recommendations. If only some of the other organisations we have had to engage with had been as efficient. We would highly recommend FPS.

Martin Steventon

Homeowner

I have used FPS, Simon and his team on several occasions over the last few years to advise on the flood risk and mitigating factors on both houses and prospective businesses. They have deep expertise and contacts across the spectrum of flood management. In particular, I have found their assessment reports invaluable. Whilst they are understandably busy, they are good to deal with and I would have no hesitation recommending them to anyone who is looking for advice in the sector.

Richard Warburton

Business Owner

FPS Environmental were great to work with. They responded immediately to my initial enquiry and followed up quickly with a quote. Their report was professionally presented and they very kindly talked me through it to understand some of the finer points. A very friendly, efficient and professional service. Thanks!

Hannah Rogers

Homeowner

We are a charity owning a large parcel of land where gathering water is then affecting neighbouring properties. Received expert flood risk and drainage advice from FPS Environmental Ltd. All dealings with them were timely and professional. Site visit arranged where we were able to fully discuss causes and solutions. Great peace of mind obtained from engaging their expertise.
