As energy costs continue to rise, many homeowners in the UK are looking for cost-effective ways to insulate their homes and reduce heat loss. External wall insulation (EWI) is one of the best solutions for solid wall properties, helping to retain heat and lower energy bills. Fortunately, several government grants and funding schemes are available to help homeowners cover the cost of external wall insulation.
What is External Wall Insulation (EWI)?
External wall insulation involves adding insulating layers to the outside of a building’s external walls, usually finished with render or cladding. This method significantly improves a home’s thermal efficiency and reduces carbon emissions.
Benefits of External Wall Insulation:
Lower energy bills – Save up to £500 per year on heating costs.
Improved energy efficiency – Enhances the EPC rating of your home.
Reduced carbon footprint – Supports the UK’s net-zero goals.
Prevention of damp and mould – Helps keep walls dry and insulated.
Enhanced property appearance – Modernizes and increases property value.
