Internal Wall Insulation

Improve Comfort, Save Energy & Cut Costs

Many homes—especially older properties with solid walls—lose a significant amount of heat through uninsulated walls. Internal wall insulation is a cost-effective way to reduce heat loss, lower energy bills, and enhance indoor comfort, making it an ideal solution for properties where external wall insulation isn’t an option.

Why Choose Internal Wall Insulation?

Lower Energy Bills

Reduce Heat Loss & Cut Costs

Without insulation, your home loses heat quickly, requiring more energy to maintain a comfortable temperature. Internal wall insulation acts as a thermal barrier, keeping warmth inside your home for longer, reducing heating costs and boosting energy efficiency.

Enhanced Home Comfort

Consistent & Warmer Indoor Temperature

Uninsulated walls can cause cold spots, making rooms feel chilly even when the heating is on. By insulating internal walls, you create a stable indoor temperature, eliminating draughts and improving overall comfort year-round.

Eco-Friendly Solution

Reduce Your Carbon Footprint

Using less energy to heat your home means lower carbon emissions, helping households contribute to sustainability goals. Internal wall insulation helps create an eco-friendly home, reducing energy consumption without sacrificing warmth.

Ideal for Solid Wall Homes

No External Changes Needed

If your home lacks cavity walls, internal wall insulation is a practical alternative to external wall insulation, allowing you to improve energy efficiency without altering the exterior appearance of your property—ideal for listed buildings or homes in conservation areas.

Increase Property Value

Boost Your Home’s Energy Rating

A well-insulated home is more attractive to buyers and earns a higher Energy Performance Certificate (EPC) rating, making your property more valuable and desirable.

ECO4 Scheme – Government Support for Energy-Efficient Home Improvements

The ECO4 (Energy Company Obligation) scheme is a government-funded initiative designed to help low-income and vulnerable households improve energy efficiency and reduce heating costs.

Under ECO4, eligible homeowners and tenants can receive free energy-saving upgrades, including internal wall insulation, helping to create warmer, more energy-efficient homes at no cost.

Who Qualifies for ECO4?

You may be eligible for ECO4 funding if:

You receive certain government benefits or meet low-income criteria

Your home has poor energy efficiency (low EPC rating).

You are a homeowner or tenant in a qualifying property.

Applying for ECO4 support could help you insulate your internal walls for free, reducing heat loss, cutting energy bills, and making your home greener.
