A passion for the environment. It's in our nature.

At Five Rivers, protecting and restoring the natural world isn't a sideline to our work — it's the reason we exist. For over 25 years, we've been a leading environmental management and environmental consultant, working across every stage of a project's life: from monitoring and survey, design and consultancy, habitat creation, ecological mitigation and on-the-ground civil engineering delivery. Our cradle-to-grave approach means we don't just design solutions - we see them through from first site visit to long-term aftercare. Our work spans river restoration, wetland creation, biodiversity net gain, natural flood management and species protection alongside the civil engineering expertise needed to bring nature-based solutions to life. Whether it's reconnecting a degraded river channel, creating new habitat for wildlife or engineering flood resilience for a community, every project is a chance to leave nature better than we found it.

We're growing, and we're looking for people who want their work to genuinely count for something.
