You could be wasting up to a third of your heating1

We’ve discovered that many homes in Hampshire are still uninsulated. And while some properties do have insulation installed, it doesn’t meet today’s recommended standards for energy efficiency.

Without insulation, a home could lose around a third of its heat through the walls, and up to a quarter through the loft or roof space1.

Could you save up to £650 a year on energy bills?2

Installing Solid Wall insulation could save householders up to £650 a year on energy costs, depending on the size and type of the property. A Solid Wall installation improves the home inside and out, creating a warm and inviting interior while giving exterior walls a refreshing facelift.

Cavity Wall insulation can reduce energy waste while keeping the home a lot cosier. Even installing something as simple and straightforward as Loft insulation could help save hundreds of pounds on energy bills year after year.
