Property details

3-bedroom semi-detached cavity wall property built as part of a development around 1979/80. 

What changes have you made to your home?

The property has cavity walls, which were retrofitted with insulation in 2005, 100mm of loft insulation underneath boards and is fully double glazed. Very recently (September 2025) the gas combi boiler was removed and replaced by a Panasonic 3kW Air Source Heat Pump, plus an unvented hot water cylinder. Several radiators were replaced with more modern double convectors. The overall SCOP (Seasonal Coefficient of Performance) of the new system is due to be 4.48. The gas hob has been replaced by an electric induction hob, and the gas meter is going to be removed by Octopus, making the property gas free and taking away the gas standing charge. 

What have been the approximate energy savings?

The heat pump system is very new, so actual savings are as yet unknown. However, the predicted costs are due to decrease from £1,189 to £922 (saving £267) per year. In addition, I will save £102.96/year for the gas standing charge. Based on these figures, the investment will pay for itself in about 10 years.
