External wall insulation is one of the most effective ways to improve your home’s thermal performance. It wraps your home in a protective, insulating layer that helps keep warmth in and cold out — without losing internal space.
Our experienced EWI installers work with high-quality systems tailored to your property type. Whether you are in a detached home or a mid-terrace, we’ll design a solution that boosts energy efficiency, improves comfort, and transforms the look of your home.
We work with a wide range of homeowners, landlords and housing providers across London and the South East. Whether you are upgrading a single property or managing insulation for a whole portfolio, we tailor our approach to meet your goals, budget and building type.
Investing in external wall insulation offers more than just lower heating bills. It changes how your home feels — every single day.
External wall insulation reduces the amount of heat escaping through solid walls. That means your heating system works less, your energy bills go down, and your home stays warmer for longer.
No more cold spots or draughts. EWI helps maintain a steady indoor temperature so your home feels cosier and more balanced throughout the year. You’ll feel the difference in every room.
