This project will see more than 1,500 council-owned flats retrofitted with cavity wall insulation to make them more energy efficient and save approximately 900 tonnes of CO2.

By February 2024, 708 of the target of 1,511 homes had been retrofitted.

Retrofitting sustainable low carbon heating equipment in older properties results in household savings of 30 to 80 per cent due to cut in energy use and a reduction of carbon outlets by 30 to 100 per cent.

However, some homes can’t have advanced technologies installed because they are very energy inefficient. For buildings to use the least amount of carbon as possible, numerous stages need to take place and the installation of cavity wall insulation is a vital one.

Better wall insulation means less energy is needed to heat the building, yielding a greater level of energy efficiency. This type of insulation means less energy is required when heating the building. It is also an effective way of cutting carbon emissions by significantly reducing the wastage of energy caused by poor insulation.

The retrofitting of buildings with more energy efficient and low carbon systems is key to lowering carbon emissions in homes.
