Leading energy supplier npower has teamed up with Build Center to offer DIY loft insulation from £1 a roll from 14 November while stocks last.

The offer means that the average three bed semi can be insulated for as little as £19 - a potential saving of £175 on annual heating bill according to the Energy Saving Trust

The scheme is open to everyone, regardless of whether they are an npower energy customer and delivery is free.
