Are you tired of high energy bills and a cold, drafty home? Internal wall insulation grants in the UK can help you create a warmer and more energy-efficient living space while saving money on your heating costs.
Internal wall insulation (IWI) is the process of adding an insulating layer to the interior surface of your home’s external walls. This layer helps trap heat inside, reducing the heat lost through the walls and creating a warmer, more comfortable living environment.
Uninsulated walls can cause significant heat loss, leading to higher energy consumption and increased expenses. In fact, according to the Energy Saving Trust UK, up to one-third of all heat loss in a home occurs through uninsulated walls. Adding internal wall insulation can help reduce the amount you spend on heating your home, as more heat stays trapped inside, making your heating system work less to keep you warm.
Internal wall insulation not only saves money on energy bills but also:
The UK government offers two primary grant schemes to help homeowners and renters access affordable internal wall insulation:
Funded by major energy companies as part of their obligation to help reduce carbon emissions, The scheme provides grants for a variety of energy efficiency improvements, including internal wall insulation, boiler upgrades, heating system repairs and replacements, and smart heating controls.
ECO4 adopts a whole-house approach, allowing eligible households to benefit from a range of upgrades that collectively enhance energy efficiency.
The GBIS scheme provides a single insulation upgrade per qualifying household, with the type of insulation determined after a property assessment to identify the most impactful improvement. This targeted approach allows the scheme to reach a wider range of homes across the UK.
Once you have accessed your EPC, look for the following information:
In the “Summary of the home’s energy performance related features” section, look for information about your wall type and current insulation status5. Your EPC should indicate:
Check your home’s current energy efficiency rating, which ranges from A (most efficient) to G (least efficient). Properties with ratings of D to G may be eligible for support under schemes like the Great British Insulation Scheme (GBIS) and ECO4
A: The cost varies depending on the size of your home, the type of walls, and the insulation material used. On average, internal wall insulation for a semi-detached home costs around £7,500.
A: Yes, both the ECO4 and GBIS schemes can provide grants to fully cover the cost of internal wall insulation for eligible households.
A: No, you must use a certified installer who is accredited to PAS 2030-2035 standards. This ensures the work is carried out to a high standard and complies with building regulations.

Internal wall insulation is a method of insulating the interior surface of external walls. It is a viable alternative to external wall insulation and, in our opinion, a superior approach for properties with appealing character. Heat loss from solid-walled properties is mainly due to heat escaping through the walls, which accounts for nearly half of the total heat loss. By insulating these walls, the rate of heat loss can be reduced, keeping the warmth inside your home for longer. Internal wall insulation involves adding an extra layer of insulation to the interior walls, which can significantly enhance the overall appearance of your property.
Our internal wall insulation is implemented by mechanically fixing and gluing insulated PIR boards onto the existing walls within your property. While insulating solid walls from the inside is typically more expensive than insulating a standard cavity wall, the resulting energy savings on your heating bills are generally more substantial.
If you want to keep your home warmer and more energy-efficient, you can insulate the walls using a method called dry lining. This involves adding insulation to the inside of your walls using one of three methods:
By insulating your walls, you can help to reduce your energy bills and make your home more comfortable to live in.
