What are the Cavity wall insulation grants?
Cavity wall insulation grants are government-funded schemes designed to help homeowners and tenants insulate their homes for free or at a reduced cost. Under the ECO4 scheme in the UK, eligible households can receive free cavity wall insulation to improve energy efficiency, reduce heat loss, and lower energy bills.

How does cavity wall insulation work?
Small holes are carefully drilled into the exterior walls, allowing insulation material to be injected inside. Once each section is filled, the holes are sealed, and the process continues until all walls are fully insulated. The final result is barely noticeable, but you’ll soon feel the difference in warmth and energy efficiency.
Cavity wall insulation is a fast and efficient upgrade for your home. Give us a call to discuss the process and check if you qualify for a cavity wall insulation grant in your area.
