Water Boreholes & Ground Source Heat Pumps in Dorking
Specialist drilling and renewable heating services for properties in Dorking and across Surrey. Free site assessment, no-obligation written estimate.
Nicholls has worked across Surrey for over 20 years, with 196 completed projects across the county to date. Properties in Dorking 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 Dorking alongside our other Surrey 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 Dorking
Dorking sits at the foot of the North Downs scarp — Upper Greensand at surface giving way to chalk at moderate depth, and Wealden Clay further south. Excellent open-loop GSHP and water-borehole conditions on the chalk side; closed-loop systems work well across the parish. The town's mix of large period properties (many off-gas-grid) and prosperous rural surrounds makes this one of Surrey's strongest GSHP markets.
Wider Surrey context: Surrey's geology varies significantly across the county. The North Downs chalk gives way to Greensand, Lower Greensand and Wealden Clay as you move south. Borehole depths and water quality differ considerably across even short distances — which is why a local desk study and site assessment is always the starting point. The Godalming and Cranleigh areas (our strongest coverage) typically sit on productive Greensand formations.
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.
