External Wall Insulation

Homes built before 1920 will normally have what is traditionally known as a solid wall. This type of construction does not have a cavity that can be filled and therefore an external or internal solution is required.

Solid walls let through twice as much heat as cavity walls so insulating your solid walls is essential and could cut your heating costs substantially. The application of an external wall insulation system can also dramatically enhance the look of your home. A three bedroom semi-detached gas heated home could save as much as £490 on annual heating costs and reduce carbon dioxide emissions by 1.9 tonnes.

Pre-fabricated houses can also benefit from external wall insulation. This improvement will not only greatly improve the thermal resistance of the building but also dramatically improve the appearance of the property (The images above show how a pre-fabricated home can be totally transformed).

Cost

The cost to install wall insulation will vary from property to property. A typical semi-detached home will cost £9,000 to £12,000 to insulate. There are some associated costs such as scaffolding, gas, electrical and other temporary and minor alterations that will also need to be added to the insulation cost but the overall cost could be reduced with an Energy Company Obligation* (ECO) subsidy. We also offer further wall insulation discounts for homeowners and tenants living in Ashford, Folkestone, Dover, Canterbury, Margate, Maidstone and other towns in Kent.

Home insulation grants

Grants schemes under the Energy Companies Obligation (ECO) were initiated by the UK Government to encourage property owners to improve the energy efficiency of their homes. The funding for these schemes is administered by the UK power companies such as British Gas, Scottish Power, E.on, npower, EDF energy and Scottish & Southern.
