Insulation is the cheapest and most important means to decrease long-term central heating running costs and make for a greener home outside of a boiler upgrade.
Roof insulation is the first port of call, as this area can cause at least 35% of heat loss in a house. It is also the lowest price material to purchase and provides the quickest means to prevent the escape of heat in a home, generated by your radiators or other heating devices.
Wall and floor insulation are next to consider, with the majority of houses built in the last century featuring cavity walls with a gap in between. Foam insulation can be padded into this cavity to combat the release of heat. Older houses with solid walls won’t be conducive to this method, so internal or external insulation will be required instead for such properties.
Window insulation is the other option – most households see around 10 per cent of their heat loss stem from window areas. The fitting of double or triple glazing can significantly curtail these losses. Plus, simple hacks like closing the curtains on colder nights and opening them on warm sunny days offers a natural heat retention practice.
