Energy at home

Reducing home heat loss

If you want to reduce your carbon emissions and keep your energy bills low, installing insulation or draught-proofing will reduce heat loss.

There are many simple yet effective ways to insulate your home, which can significantly reduce heat loss while lowering your heating bills.

Even little fixes around the home can mount up to significant savings in your energy bills. For example, fitting your hot water cylinder with an insulating jacket will save you £18 a year in heating costs and 110kg of carbon dioxide emissions.

Whether you are looking for quick wins around your home or a professional to install insulation, the suggestions below will help maintain a constant temperature in your home.

Cavity wall insulation

About a third of all the heat lost in an uninsulated home escapes through the walls. By properly insulating cavity walls, you will save energy and cut costs off your heating bill.

Solid wall insulation

Insulating your solid walls could cut your heating costs considerably, and make your home more comfortable. If your home was built before the 1920s, its external walls are probably solid walls rather than cavity walls.

Floor insulation

Insulating your ground floor, or any floors above unheated spaces like garages, will help keep the heat in your home. Newer homes generally have ground floors made of solid concrete while older homes are likely to have suspended timber floors.

Roof and loft insulation

You can lose 25% of heat through the roof of an uninsulated home, so insulating your loft or roof is a great way to lower your heating bills.

Draught-proofing

Draught-proofing is one of the most cost-effective ways of keeping your energy bills low. Heat can escape your home from any gaps, holes or cracks, from gaps in windows and doors through to open chimneys.

Windows and doors

Double or triple glazing your windows will help reduce heat loss. You can replace an external door with a more energy-efficient one, or install draught-proofing measures.
