Clapham homes: Georgian, Victorian and converted flats
The Georgian houses around Clapham Old Town and the north side of Clapham Common often have pipework and heating that have been altered and extended over many decades.
Much of SW4 is Victorian terraces, many now converted into flats. Conversions usually mean each flat has its own combi boiler, often in a cupboard or kitchen, and bathrooms stacked above one another. A slow leak upstairs can soon become a ceiling problem downstairs.
Landlord gas safety in Clapham
Clapham has a large rental market, from house shares to flats. If you let a property with gas appliances, you need a Landlord Gas Safety Record every 12 months and must give tenants a copy of the record. We carry out LGSR checks for individual landlords and letting agents.
