Installing more insulation in walls and roofs isn’t necessary for having a heat pump – they still work well in homes with less insulation. However, a recent poll carried out by YouGov on behalf of Energy Saving Trust shows that only 29% of Brits know this3.
To qualify for a government grant towards installing a heat pump your home must have a valid Energy Performance Certificate (EPC) with no outstanding recommendations for cavity wall or loft insulation, or evidence to show why these measures aren’t possible.
If you aren’t able to top up your home’s insulation, a heat pump system could still be designed to work well in your home depending on your heating needs and property type. This may involve installing larger radiators and programming your heat pump to come on at the optimal times to get your home up to the right temperature.
