Clapham's housing stock is heavily weighted towards Victorian and Edwardian properties — many with three or four storeys, multiple bathrooms, and original cast-iron radiators. These homes have very different heating requirements to a modern flat, and getting the boiler specification right is critical for both comfort and efficiency.
Our engineers regularly work on the large family homes around Clapham Common Northside and the Edwardian terraces of Clapham Old Town, as well as the more recent developments near Clapham North and Clapham High Street.
We partner exclusively with Worcester Bosch and Vaillant, offering up to 10-year manufacturer warranties on all installations. See the full range on our boilers page.
Many Clapham homes have had extensions, loft conversions, or basement dig-outs that place additional demand on the heating system. We often find that the existing boiler was never upsized to match. Our free survey includes a full heat-loss calculation to ensure your new boiler is correctly rated for your entire property — including any additions.
We also handle the particular challenges of terraced properties: routing flues through party walls, working in tight kitchen spaces, and keeping disruption to a minimum with neighbours in close proximity.
A straightforward combi swap in a Clapham flat takes one day. Larger homes converting from a conventional system to a sealed system typically need two days. We schedule at your convenience, including Saturdays, and always leave your home clean and tidy.
Your installation includes a power flush, magnetic filter, wireless thermostat, and full Gas Safe certification. Protect your investment with a Heat-Plex service plan and never worry about unexpected breakdowns.
We serve Clapham Common, Clapham North, Clapham South, Clapham Old Town, Clapham Park, and Abbeville Village. For emergency plumbing or gas safety certificates in Clapham, we're just a call away.
