Heat pumps for UK retrofit: why installers should focus on older homes for low-carbon heating

With nearly 80% of UK homes built before 1980, the retrofit market is a major opportunity for installers to drive decarbonization. Heat pumps, like Mitsubishi Electric's Ecodan R290, are becoming easier to install in older homes, even those with microbore pipework. A trial by Sovereign Network Group showed installations completed in under three days with a 40% reduction in time by keeping existing pipes. High-temperature heat pumps now deliver around three units of heat per unit of electricity, using natural refrigerant with ultra-low global warming potential. This makes them a practical alternative to gas boilers in many existing homes. Installers can reduce costs and disruption while tapping into growing demand for low-carbon heating. The article highlights that modern heat pump technology can overcome common barriers like radiator upgrades and extensive retrofits. For installers, this means new business opportunities in both social housing and private homes, backed by government support and rising consumer awareness.
