Home insulation is a way of preventing heat escaping from your property. Here at npower we offer two types of home insulation; cavity wall and loft and you could be entitled to receive it FREE of charge.
It sounds too good to be true but there are no catches. If you or someone if your household is in receipt of State Pension Credit or Child Tax Credits (where relevant income is less than £16,190) then npower will fully fund the installation and you don’t even need to be an npower customer.
There is a Government scheme to insulate people’s homes to protect them from the cold and to save them money on their heating bills. More than two and a half million homes have already benefited from the scheme and we want to make sure you are getting what you are entitled to.
If you have less than 60mm of loft insulation then we recommend this is increased to 270mm. Why not download our handy ruler to see if you have enough. Or if can’t get to your loft, don’t worry, our installer will look for you.
According to the Energy Saving Trust, you could be wasting as much as £1 in every £4 you spend on heating due to poor insulation. Loft insulation could save you up to £175 off your energy bills every year and cavity wall insulation up to £135.
Keep your home warm this winter and start saving money on your energy bills.

The Carbon Emission Reduction Target requires larger gas and electricity suppliers to reduce carbon emissions in domestic properties. In the first three years of the scheme 2.5 million properties have received professionally installed insulation measures.
