Can EWI Increase the Value of My Property

When it comes to increasing the value of your property, homeowners often look for ways to improve the aesthetics or functionality of their homes. One often overlooked aspect of home improvement is enhancing energy efficiency. This can not only save you money on energy bills but also potentially increase the value of your property. A popular method to achieve this is through external wall insulation (EWI). In this blog post, we will explore how EWI can improve your home’s energy efficiency and, in turn, potentially increase its value.

External wall insulation is a layer of insulating material applied to the exterior walls of a building. This layer is then covered with a protective finish, such as a render or cladding. The primary purpose of EWI is to reduce heat loss through the walls of the building. This significantly improves energy efficiency and provides a more comfortable living environment.

There are several reasons why EWI can potentially increase the value of your property. The most notable benefits include energy efficiency, reduced energy bills, and improved curb appeal.

Energy Efficiency

One of the main advantages of installing EWI is improving your home’s energy efficiency. Walls are responsible for approximately 35% of heat loss in uninsulated homes. By adding insulation to the external walls, you can significantly reduce this heat loss, making your home more energy-efficient. This improvement can be particularly appealing to potential buyers, as it demonstrates that the property has been well-maintained and cared for.

Reduced Energy Bills

As a direct result of increased energy efficiency, you can expect to see a reduction in your energy bills. This reduction can be up to 40% in some cases, depending on the type and thickness of the insulation used. In practical terms, that can amount to almost £1,000 worth of savings per year. Lower energy bills are an attractive selling point for potential buyers, as they represent long-term savings. This also demonstrates that the property is cost-effective to run.

Improved Curb Appeal

External wall insulation can also improve the appearance of your property. The layer of insulation is covered with a finish that can come in various colours and textures, allowing you to choose a style that complements your home. This can enhance the curb appeal of your property, making it more attractive to potential buyers. For example, pebbledash can be particularly unsightly, especially when placed directly next to a newly retrofitted home with a shining new Silicone Render facade.

In addition to these three main benefits, EWI can also improve the overall comfort of your home. By reducing drafts and cold spots, the insulation can create a more even temperature throughout the property, making it more comfortable to live in. This increased comfort can be an additional selling point for potential buyers.

While there are many advantages to installing EWI, it’s important to consider the potential drawbacks as well. The initial installation cost can be significant, and it may not be suitable for all properties. It’s crucial to consult with a professional to determine if EWI is the right choice for your home and to ensure proper installation.

It’s also important to consider how EWI will affect your property’s appearance. While the insulation can improve curb appeal, it will also change the look of your home. This may not be an issue for some homeowners. However, it’s worth considering if you have a period property or a home with unique architectural features.

Despite these potential drawbacks, external wall insulation can be a valuable investment for many homeowners. The improved energy efficiency and reduced energy bills can make your property more attractive to potential buyers, and the enhanced curb appeal can also increase its value. However, it’s essential to carefully weigh the pros and cons and consult with a professional before deciding whether EWI is the right choice for your property.


In conclusion, external wall insulation has the potential to increase the value of your property by improving energy efficiency, reducing energy bills, and enhancing curb appeal. These factors can make your home more attractive to potential buyers, which may result in a higher selling price. However, it’s crucial to carefully consider the initial costs, potential drawbacks, and the impact on your property’s appearance before deciding to invest in EWI.

Another aspect to consider is the potential return on investment (ROI) of EWI. While the initial cost may be substantial, the long-term savings on energy bills and the increased property value can help offset these expenses. To calculate the potential ROI, it’s important to factor in several things. The installation costs, the expected energy bill savings, and the estimated increase in property value affect the calculation. This will give you a better understanding of whether EWI is a worthwhile investment for your specific property.

Moreover, it’s essential to research any grants or incentives available for energy efficiency improvements in your area. Many governments and local authorities offer financial support for homeowners who choose to invest in energy-saving measures such as EWI. These incentives can help offset the initial costs and make the investment even more appealing.

Finally, it’s important to remember other factors also contribute to a property’s worth. The location, size, and overall condition of the home, as well as the current housing market, all play a role in determining a property’s value. Therefore, it’s essential to view EWI as just one of many possible improvements.
