Benefits of external wall insulation
Exterior EWI adds a new weatherproof layer to your building and dramatically slows the movement of heat through your walls — transforming comfort and reducing energy costs.
What EWI does for your home
Exterior external wall insulation adds a new weatherproof layer to the building, as well as slowing the movement of heat through the walls. Another advantage is that external wall insulation causes the temperature of the walls themselves to rise.
This means that water vapour from cooking, washing or drying clothes will no longer condense on the freshly insulated walls — preventing damp and mould.

Sustainability and carbon reduction
The environmental impact of carbon emissions is increasingly relevant, and our solutions reduce the carbon footprint of buildings. This is achieved by protecting buildings from heat loss, enhancing external appearance and improving thermal efficiency — all of which reduces energy usage and carbon output.
A well-insulated home uses significantly less gas and electricity to maintain a comfortable temperature. Our work across Brighton and Hove, Hastings and Eastbourne reflects this commitment to sustainable building.
Real results from real customers
“There is a noticeable difference within the house — heat is kept out for longer during the day and it is most definitely warmer in the morning.”Max W, Brighton
“An unexpected bonus is that the insulated rooms are much quieter. Overall I’m very happy with the result and recommend it.”Heather M, Worthing
Grants for external wall insulation
Various government grant schemes have been available to help homeowners fund energy efficiency improvements including external wall insulation. We recommend checking the latest available schemes at the time of your project — eligibility and funding levels change regularly.
Previous schemes have offered funding of up to £5,000 towards qualifying energy saving measures. Your local council and energy supplier may also offer additional support.
Call us to discuss your project and we can advise on any applicable funding we are aware of at the time. You can also see our full pricing guide for a sense of typical EWI costs.
