How much do I need?

If your house is over 10 years old, the chances are you could benefit from additional loft insulation. Current building regulations recommend a minimum installed depth of 270mm. In 1985 this was as little as 100mm and in 1990 only slightly improved to 150mm.

With ever increasing energy prices it’s widely recognised that thicker insulation brings significant improvements to the energy efficiency of homes.

You can easily check if your home is up to the latest regulations by measuring the distance from the top of your insulation to the ceiling material below. Or simply contact us for your free no obligation survey.

If you currently have no insulation at all in your loft and install the recommended 270mm depth you could save up to £180 a year on your heating bills and around 730kg of CO2 per year*

In most properties we’ll almost invariably see some level of insulation. Unfortunately in many older properties this can be as little as 25mm of rather dust caked, very poor material. In these cases its usually best to leave the old insulation in situ so as not to disturb the fibres and dust and make your home uncomfortable.

We would then install a 100mm deep base layer of insulation that fits between your joists before moving onto the top layer. In buildings constructed since 1985 there is usually enough insulation present to act as an efficient base layer already.

To get to the desired depth of 270mm we then install a top layer of 170mm insulation laid in the opposite direction to the bottom layer in order to eliminate any cold joints

Helen from Filton

Thank you for the great job on our loft. I’d happily recommend you to friends and family. I really like that you have all your prices set out on a price list, it made me feel that you were treating us fairly from the outset… it doesn’t always feel that way with other trades!!! You left everything so neat and tidy too. Thanks again.

Simon from Yate

Hi Jeff, wanted to quickly thank you for the recent work you carried out at our property, the extra storage that the removal of the header tank platform and fitting of shelving has given us is perfect. The fitting of the loft ladder, particularly in what was a rather precarious location and the installation of boarded flooring has made access to the loft much safer and more convenient. Your professional manner, very reasonable pricing and quality workmanship leaves no doubt in my mind that I will be recommending your services to friends and family.

Stuart from Keynsham

Thank you for the lovely job in the loft. Particular thanks for keeping disruption in the house to such a minimum and leaving everything so clean and tidy, much appreciated.

Lisa from Whitchurch

The attic looks fantastic, thank you for such a brilliant job. Just a shame you only do loft work as otherwise I’d get you to do all the work on my house!
