The cost of heat pump installation in London can vary significantly depending on factors such as the type of heat pump, the size of your property, and the complexity of the installation. For air-source heat pumps, you can expect to pay between £7,000 and £14,000, including installation. Ground-source heat pumps are generally more expensive due to the need for extensive excavation, with costs ranging from £15,000 to £35,000.
Other factors influencing the price include the need for additional components, such as underfloor heating systems or upgraded radiators, and whether any preparatory work is required, like improving insulation. Keep in mind that while the upfront cost may seem high, heat pumps are energy-efficient systems that can significantly reduce your heating bills over time. Additionally, government schemes like the Boiler Upgrade Scheme may provide grants to offset the installation cost, making heat pumps a more affordable and sustainable heating solution in the long run.
