These are some of the energy saving improvements that you could carry out to your home. If you are applying under the Warm Homes Local Grant they may be recommended.

The Centre for Sustainable Energy have produced a number of downloadable fact sheets, on topics such as air source heat pumps, solar PV, ventilation and various types of insulation.

Air source heat pump

An air source heat pump is an energy efficient alternative to a gas or oil boiler. An air source heat pump transfers heat from the outside air to the water in your central heating system (even when it feels cold outside). This heats rooms in your home via radiators or underfloor heating. It can also heat water stored in a hot water cylinder for your hot taps, showers, and baths.

Cavity wall insulation

If your home was built since the 1930s, it is likely that the external walls are made of two 'skins' with a small gap between them. This means they are cavity walls and the gap between them can be filled with insulating material to slow the rate of heat loss to the outside.

Door undercut

This is where you have a 10mm gap between the bottom of the door and the bottom of the door frame. It will increase air circulation between rooms when the door is closed, helping maintain a balanced temperature in the property, and control moisture levels. This is important to avoid damp, condensation and mould.

Double glazed windows

Windows that have two panes of glass with a gap between them. This reduces heat loss.

Draught-proofing

Blocking gaps in your home's construction to keep warm air in and cold air out.

External wall insulation

External wall insulation is installed on the outside walls of a building. It helps make the building more energy efficient by reducing heat loss.

Insulation

A layer of material that slows down heat loss. It's the first step in keeping your home warmer.

Loft insulation

Insulation installed in a loft, which helps slow heat loss through the top of your home.

Room in roof insulation

This is insulation in rooms that are in the roof space, for example a loft room.

Solar PV panels

Energy from the sun can be converted into electricity using solar photovoltaic panels, known as 'solar PV', installed on your roof. This electricity can power your home and reduce your energy costs.

Ventilation improvements

Ventilation is essential to keep your home healthy, allow some fresh air inside, and reduce issues such as damp and mould. In order to comply with national standards (PAS2035) there is a requirement not to make the building airtight. For example, loft Insulation may require a series of vents.

Any insulation improvements, including new windows or doors, are likely to require the installation of ventilation. This may include replacing existing bathroom or kitchen fans.

These videos from Aereco explain more about why we need ventilation and the types of ventilation.
