Internal Wall Insulation Grants: A Complete Guide to Free & Subsidized Home Insulation

The Internal Wall Insulation Grants scheme is a government-funded initiative designed to help homeowners and tenants improve their home’s energy efficiency. If your home has solid walls and lacks insulation, you could qualify for free or subsidized internal wall insulation under programs like the ECO 4 Scheme and Home Energy Scotland Grant. Installing insulation inside your home can significantly reduce heat loss, lower energy bills, and enhance comfort.

What is Internal Wall Insulation?

• Lowers heating costs, saving up to £375 per year on energy bills.

• Prevents damp and condensation by regulating indoor temperatures.

• Enhances indoor comfort by maintaining a steady temperature.
