A quarter of the heat loss in your house could be escaping through the roof so loft insulation is another great way to cut your heating bills and reduce carbon emissions.
There are various types of insulating materials but it usually needs to be about 270mm thick and will begin to lose it’s effectiveness after about forty years. So even if you already have insulation it’s worth checking its age and depth.
Laying loft insulation where there is none already should pay for itself within two years, as well as saving a staggering one tonne of carbon annually. Topping up your loft insulation will also make you great financial savings and reduce your carbon output by about 300kg.
Over 70’s and people on certain benefits may be eligible for free loft insulation.
