Water Boreholes & Ground Source Heat Pumps in Crawley
Specialist drilling and renewable heating services for properties in Crawley and across West Sussex. Free site assessment, no-obligation written estimate.
Nicholls has worked across West Sussex for over 20 years, with 227 completed projects across the county to date. Properties in Crawley can benefit from the same in-house design, drilling, installation and servicing teams that have completed water boreholes and ground source heat pump systems for homeowners, farms and commercial sites across the wider region.
We work Crawley alongside our other West Sussex projects — free site assessment, geological desk study and a written estimate before any work starts. If a borehole or GSHP isn't the right fit for your site, we'll tell you straight.
Geology around Crawley
Crawley sits on Tunbridge Wells Sand of the High Weald — sandstone aquifer at moderate depth, often with iron and manganese in solution. Boreholes typically 70-110m. The town's industrial and commercial estates show stronger commercial-borehole demand than residential; the rural fringe around Pease Pottage and Ifield offers strong GSHP potential for off-gas-grid properties.
Wider West Sussex context: Much of southern West Sussex sits above the chalk aquifer — one of the most productive groundwater sources in England. Boreholes in the Chichester and Arundel areas typically reach productive water between 30m and 80m depth. The Wealden Clay belt around Billingshurst, Kirdford and Horsham requires deeper drilling into the underlying sandstone, and water from this geology often requires iron and manganese treatment before use. The Lower Greensand around Pulborough and Storrington offers good yields at moderate depth.
Every site is different. A site-specific desk study is the starting point for any project — we cover that as part of the free site assessment.
