Water Boreholes & Ground Source Heat Pumps in Farnham

Specialist drilling and renewable heating services for properties in Farnham 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 Farnham 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 Farnham 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 Farnham

🧭

Farnham is on the Lower Greensand of west Surrey, with chalk to the north. The Greensand offers reliable aquifer conditions for water boreholes at moderate depth. Closed-loop GSHP works well across the area; the local property mix (many large period homes plus rural estates) sees strong demand for both water supply and heat-pump installations.

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.
