Windows, Doors & Secondary Glazing in Central London

Central London is defined by its historic townhouses — the Georgian terraces of Islington, Bloomsbury and Marylebone, the Regency stucco of Pimlico and the grand period homes of Kensington, Chelsea and Westminster.

An enormous proportion of these properties are listed or fall within strict conservation areas, where replacing original windows is simply not allowed. This is where our discreet, reversible secondary glazing comes into its own: it cuts heat loss by up to 75% and traffic noise by up to 80% while leaving the original sashes completely untouched — typically with no planning consent required. It's the specialist solution Central London's protected homes need.
