Cut your energy bills by up to 60%

Cut your energy bills by up to 60%

A new home retrofit study by the UK’s innovation agency, the Technology Strategy Board,  with the support of the Energy Saving Trust, has demonstrated that retrofitted homes used as little as a quarter of the energy per square metre as a typical home of the same size.

The study report outlines the key lessons from the four-year Retrofit for the Future programme. The report is a guide on how to maximise the benefits of retrofit to reduce energy consumption in existing homes.

The study report funded the retrofit of 100 home retrofit projects across the UK.  The study revealed a ‘best case’ energy use of 74% less than a typical English home per square metre and 60% lower energy bills.  For a large proportion of the monitored homes, energy use was 48% lower per square metre and energy bills were 35% (£380) lower.

In one home, the fabric insulation helped reduce annual space heating demand by as much as 95 per cent, illustrating the importance of good insulation. Almost all the homes significantly reduced heat loss by insulating the fabric (walls, roof, floors, windows and doors), and the most comprehensive approaches paid additional attention to insulation continuity, such as thermal bridges and air-tightness at critical junctions and openings.
