Water Boreholes & Ground Source Heat Pumps in London
Over 80 projects completed across London. Free site assessments and no-obligation estimates.
London is a significant and growing market for Nicholls with over 80 completed projects across the capital. Our work in London is predominantly ground source heat pump installations — the dense urban environment and premium property market make GSHP an attractive renewable heating option. We also deliver water boreholes, soakaways and increasingly data centre cooling solutions along the western corridor.

Learn more →Local geology in London
London's geology is dominated by London Clay — challenging for water boreholes but excellent for closed-loop GSHP installations due to its consistent thermal properties. Chalk is accessible at depth (typically 50-100m) in some areas. The Thames gravels provide localised aquifer potential. Our strongest areas — Wimbledon, Putney and Kensington — sit on London Clay, with most projects being GSHP installations for high-value residential properties.
Every site is different. A desk-based geological assessment is always the starting point for any project.
