The installation cost of a heat pump will differ from house to house and from size and type of heat pump chosen. As a rule of thumb, an air to water heat pump will cost around £8k to install and a ground source heat pump could be anything up to and around £20k. This though is very dependent on the site and as to whether the existing heating system can be used and the position of the equipment etc.
There are grants available to assist in the investment, sometimes locally and regionally, as well as The Boiler Upgrade Scheme, a government incentive that will assist with the upfront cost of upgrading your heating system with one of our air to water and ground source heat pumps. In addition, there is now no VAT on heat pumps – reducing the cost even further.
