Waltham Forest, in north-east London, was formed as a borough in 1965 from the former Essex municipal boroughs of Leyton, Walthamstow and Chingford. Its name recalls the ancient royal forest that once covered the area, and the southern part of Epping Forest — largely preserved under the Epping Forest Act 1878 — still reaches into the north of the borough around Chingford.
Walthamstow is the birthplace of William Morris, the designer and leading figure of the Arts and Crafts movement. His family home from 1848 to 1856, Water House in Lloyd Park, opened as the William Morris Gallery in 1950. The borough's housing is mostly Victorian and Edwardian terraces, including Walthamstow's distinctive Warner flats, along with inter-war homes in Chingford — many with ageing heating systems.
Much of Waltham Forest is Victorian and Edwardian terraces — in Walthamstow, Leyton and Leytonstone — with inter-war homes further north towards Chingford and Highams Park. Walthamstow's Warner flats and the many converted terraces usually suit a compact combi, while larger houses may need a system boiler. We often clean older pipework with a MagnaCleanse before fitting a new boiler, and add modern controls so heating is easier to manage.
