External wall insulation and rendering by Enzo Construction in East London

Many of East London's Victorian and Edwardian homes were built with solid walls that let heat pour out and bills climb. External wall insulation (EWI) wraps the outside of your home in an insulating layer and a fresh render finish — making it warmer, cheaper to run and better looking. Here's what it involves for homes around Bethnal Green and Stepney.

Why solid-wall homes lose so much heat

Homes built before the 1920s typically have solid brick walls with no cavity to insulate. In winter that means heat escapes straight through the brickwork, rooms feel cold and draughty, and radiators work overtime. Solid walls are one of the biggest sources of heat loss in older London housing.

How external wall insulation works

We fix insulation boards to the outside of your external walls, then finish them with a reinforced, weatherproof render. Because the insulation sits outside the structure, it keeps the warmth in without losing any internal floor space — a real advantage in compact East London homes.

The benefits beyond warmth

As well as a warmer home and lower energy bills, EWI reduces draughts and cold spots, helps control condensation and damp, protects the brickwork from the weather, and gives tired frontages a clean, modern finish. It's one of the highest-impact upgrades you can make to an older property.

Finishes and considerations

Render comes in a range of colours and textures, and detailing around windows, sills and rooflines needs care to look right and perform well — especially in conservation areas, where appearance is scrutinised. We advise on finish, handle the detailing properly and make sure the system is installed to last.
