We install air source heat pumps in partnership with

Clapham, spanning areas such as Clapham Common, Abbeville Village, and near Clapham Junction, blends period buildings with modern flats—and many homeowners here are seeking reliable, efficient alternatives to traditional gas heating. Air source heat pumps are increasingly viable for properties in SW4, particularly where outdoor space exists for the outdoor unit, or where internal space allows for cylinders. WPJ Heating offers full installations of air source heat pumps in Clapham, helping you make your home more sustainable while enjoying long-term energy savings. For homeowners considering system upgrades, we also provide expert boiler installation in Clapham, ensuring your property has the right heating solution for its layout and needs.
Working through our partnership with Heat Geek, we supply and install high-efficiency Vaillant heat pump systems and the matching hot water cylinders, fully certified and registered. These systems can provide heating output up to four times the energy they consume, helping reduce energy bills and carbon emissions. For households without an existing cylinder, we help plan locations that minimise pipe runs and optimise performance. Eligible Clapham homeowners may also benefit from the £7,500 Boiler Upgrade Scheme (BUS grant), which eases the transition to this type of renewable heating.
Installation in Clapham demands careful planning. Many homes are terraces or converted flats with limited space; ensuring the external unit is sited appropriately—as on a side return, garden, or discreet external wall—is essential. Also important is improving insulation, sealing drafts, and upgrading glazing, since many older Clapham homes allow heat to escape. A well-insulated home ensures the heat pump works efficiently, lasting longer and delivering better value.
Costs typically start from £12,000 + VAT (after BUS grant), though the final price depends on property type, alterations needed, insulation improvements, and accessibility for installation. WPJ Heating conducts surveys in Clapham, provides clear cost break-downs, and ensures you understand all aspects before proceeding.
