What Is Internal Wall Insulation?

Internal Wall Insulation (IWI) means fitting insulation materials such as rigid boards or stud wall systems to the interior of your external walls. It keeps warmth within when the weather gets cold, making your building more energy-efficient and less reliant on excessive heating.
It’s well-suited to properties with solid walls, particularly those constructed before the 1930s that were not built with insulation.

Government Schemes That Finance Internal Wall Insulation

ECO4 Scheme
The UK government ECO4 (Energy Company Obligation) scheme is an initiative to minimize carbon emissions and fuel poverty. This scheme provides fully funded upgrades for low-income and vulnerable households for energy efficiency, such as internal wall insulation.

Great British Insulation Scheme (GBIS)
Launched as part of the government’s “Help to Heat” initiative, GBIS is focused on homes in council tax bands A-D with low energy efficiency. It is not limited to benefits claimants, so you can benefit from free or heavily reduced insulation even if you’re not receiving benefits.

Key Advantages of Internal Wall Insulation

Lower Heating Costs

Internal wall insulation keeps your home warm for longer. That means your boiler isn’t working as much, so it uses less energy. Over time, you’ll notice a significant drop in your heating bills.

Increased Comfort

Say goodbye to cold spots and chilly rooms. Insulated walls provide a consistent indoor temperature year-round. Your home is a warmer, more comfortable environment to be in.

Reduced Heat Loss

Solid walls with no insulation lose heat quickly. Internal insulation provides a thermal barrier that traps warmth indoors. This ensures your home remains warm even in subzero weather.

Environmentally Friendly

Using less energy means lowering your carbon footprint. Insulating the walls lowers carbon emissions from heating systems. It’s a good move towards the UK’s net-zero strategy.

Better EPC Rating

Improving your energy performance makes your home more efficient. The higher the EPC rating, the higher the property value. This also makes your property more desirable to prospective buyers or renters.

Zero Upfront Cost

There is no need to spend money from your pocket. The materials and installation costs are paid for with ECO4 or GBIS. If you are eligible, you get the upgrade for free.
