If you have been researching how to improve the thermal efficiency of your home, then you’ve probably come across external wall insulation. This layered insulation system creates a thermal barrier around your property that prevents heat from escaping in the winter and prevents hot air from outside entering during summer.

The improvement can reduce your heating bills, noise pollution, damp, and condensation, but how much does external wall insulation cost? We’ll be answering that question here, as well as providing advice on how the cost can be offset against potential savings and what grants may be available.

How much does external wall insulation cost?

It’s important to understand that the cost of external wall insulation is variable as each EWI supplier will have its own pricing, and the market is constantly changing. However, there are some things that may affect the total cost of external wall insulation that you should keep in mind.

Ways to reduce the cost of external wall insulation

External wall insulation is an investment that is definitely worth paying out for. However, in the UK, you may be eligible for a government-backed grant for improvements that increase your home’s energy efficiency, such as external wall insulation.

The ECO (Energy Company Obligation) scheme is the main scheme for helping those in low income or vulnerable households to make energy-efficient improvements to their home. The current scheme is ECO3 and will run until 31st March 2022. The scheme obliges medium and large energy providers to help with the cost of energy-efficient improvements such as external wall insulation.

If you live in social housing that has a low energy efficiency rating (E or lower) you should be eligible for an ECO grant. To find out about the current funding availability in your area, please use our questionnaire.

It is also worth getting in touch with your local authority to see if there are any schemes to reduce the cost of external wall insulation in your area.

External wall insulation is an investment that can save you money in the long run

It’s also worth considering the long-term savings against the initial cost of external wall insulation. EWI will save money in the long run because it improves your home’s thermal efficiency and can reduce heating bills by 50% annually.

External wall insulation could also potentially increase the resale value of your property. The new finish provided by EWI gives your home more kerb appeal, and an energy-efficient home is more appealing to potential buyers because it reduces their carbon footprint and costs less in energy bills. 

EWI also improves a property’s soundproofing, which can be another selling point for potential buyers. You can read more about the effects EWI can have on your home’s value in our previous blog.

 

External wall insulation may have a sizeable upfront cost, but this will soon be offset by the savings you make both on your energy bills and by potentially increasing the resale value of your property. Just be sure to check whether you are eligible for any grants before you book your installation!
