Home / Campaigns / The Big Loft Insulation Drive The Big Loft Insulation Drive Save money this winter and keep the heat in by insulating your loft. It’s easier than you think. With energy bills going through the roof, The Big Loft Insulation Drive is here to help you stop the heat in your home from escaping so your energy bills are lower. If you have no loft insulation, professional installation of the recommended 270mm in a typical semi-detached house costs £930. If you decide to do it yourself, the average cost is £630. You could make savings of £285 a year, meaning you will have paid for the cost of installation in roughly three years. If you live in one of the eight million homes in the UK without adequate loft insulation, you could be losing around a quarter of the heat in your home through your roof. UK households are collectively spending an estimated £8.1 billion per year on wasted energy in the home. It’s a staggering amount but our mission is to change all that. Installation is quick and easy! Put your feet up while a contractor does the job in just one afternoon. Or do the job yourself! We’ll help you decide which option is right for you. And you can keep using the attic for storage space if desired. The recommended depth for loft insulation is 270mm – roughly the length of a school ruler. If you have less than this, you will benefit from topping up. If you don’t know how much you have, go to our Find out more page to read about how to check this.
