Exterior wall insulation (EWI) is a type of insulation that is installed on the exterior walls of a building. It is used to help improve the energy efficiency of a building by reducing the amount of heat loss through the walls. This can help to lower energy bills and make a building more comfortable to live or work in.
There are several different exterior wall insulation materials that can be used, including fiberglass, cellulose, and foam. Fiberglass insulation is made from strands of glass that are spun into a mat and then bound together with a resin. It is a common and affordable option for exterior wall insulation. Cellulose insulation is made from recycled newspaper and other paper products and is treated with fire retardants to make it more durable. Foam insulation, which is made from polyurethane or other synthetic materials, is known for its high level of insulation and is often used in new construction.
Installing exterior wall insulation involves a few different steps. First, the area where the insulation will be installed must be prepared. This includes removing any siding or other materials that may be covering the walls, as well as repairing any damaged areas. Next, the insulation material is cut to fit the walls and installed using special adhesives or fasteners. Finally, the siding or other exterior materials are replaced to cover the insulation.
Exterior wall insulation can provide a number of benefits to building owners. In addition to improving energy efficiency, it can also help to reduce noise pollution, increase the value of a building, and improve indoor air quality. It is an effective way to save money on energy costs and make a building more comfortable and efficient.
The average exterior wall insulation cost can range from £8,000 for a small flat to £22,000 for a large detached house.
Exterior wall insulation (EWI) is a worthwhile investment for many building owners. It can help to reduce energy costs, improve comfort, and increase the value of a building.
ECO4 is backed by large and medium energy suppliers. They have legal obligations under the Energy Company Obligation (ECO) scheme. This includes companies like British Gas, EDF Energy, E.ON, Scottish Power, and Octopus Energy.

Following the Chancellor’s budget, the UK Government has confirmed that the ECO4 energy efficiency scheme will end in March 2026, with no replacement planned. Chancellor Rachel Reeves has announced the ECO4 scheme will end in March 2026. This grant opportunity has helps thousands of UK households on low incomes or with health conditions that make them vulnerable to the cold, access to a warmer/energy-efficient home. It’s deeply concerning to see this support being cut.
If you’ve been considering making your home more energy-efficient, the ECO4 scheme has been by far the most effective grant scheme and way to improve both energy efficiency and affordability. From solar panels and air source heat pumps to modern high-heat storage heaters, gas boilers, and insulation, ECO4 helps you upgrade your home with essential improvements.
