We are a proud, family-owned business established in 1989. For over 25 years, we have specialised in the construction and refurbishment of Biological Trickling Filters and other filter beds at Municipal Waste Water Treatment sites and in various industries. This has been our core business, and we are recognised as one of the most experienced contractors in this field in the UK.

We provide a fully UK-wide service, supporting clients nationwide, and we work closely with our clients to deliver custom solutions and bespoke services tailored to their specific requirements. Our reputation within the industry is excellent, with highly positive feedback from our clients leading to numerous contracts through recommendations.

At Bagnall Environmental, our expertise spans a wide range of specialist cleaning and infrastructure services. Below are our four core service areas, which represent the most in-demand and mission-critical work we deliver for both municipal and industrial clients across the UK.
