It's the question we get asked more than any other: is loft insulation actually worth the money? For most Sussex homeowners the honest answer is yes, but how much difference it makes depends on your home type, the insulation you have now (if any) and how you heat the house.
Sussex homes vary a lot
Brighton, Hove and Hastings have many Regency and Victorian terraces with older roofs. Crawley, built as a New Town after the war, has a lot of post-war semis and terraces, while coastal towns such as Worthing, Bognor Regis and Seaford have a great many bungalows, whose large lofts sit over every room in the house. A loft with nothing in it gains the most; a loft with 100mm of dry insulation usually benefits from a top-up to 270mm.
Heat loss through the roof
The Energy Saving Trust says a home can lose around a quarter of its heat through an uninsulated roof. Sussex's mild, often damp coastal climate means homes lose heat for much of the year, not only in deep winter: even in spring and autumn a cold loft draws warmth up through the ceilings.
What it costs and what you save
We don't publish headline prices or promise a saving, because both depend on your loft and your energy use. The price depends on the loft area, access, what is already there and the material that suits it: see what affects the cost. For typical savings by house type, the Energy Saving Trust publishes current estimates.
