For homeowners and small businesses
The UK Boiler Upgrade Scheme (BUS) offers grants of up to £7,500 to help cover the cost of installing an air-source or ground-source heat pump. This grant is available to homeowners and small businesses looking to replace their existing oil, gas, LPG, or electric heating with a low-carbon alternative.
Currently, heat pump installations also benefit from 0% VAT, reducing the upfront cost even further until at least 2027. At Sussex Renewable Heating (based in Worthing, Sussex), we can guide you through the available grants and application processes, ensuring you can access all the support that you are entitled to.

Harry is a really nice person & easy to relate to. He responded very quickly when he heard that we had no hot water. The air pump system in our new build has been fitted with many errors. He returned with his excellent electrician & rectified a lot. For the first time, It is working as it should. He is very knowledgeable about the various models of pumps...
