Heat-Plex provides expert heating and plumbing services throughout the London Borough of Wandsworth. Our Gas Safe engineers serve Wandsworth Town, Earlsfield, and Southfields with professional boiler installations and repairs across SW18.
Wandsworth covers a broad swathe of South West London, from the riverside pubs and Young's Brewery development in Wandsworth Town through the family-friendly streets of Earlsfield to the leafy avenues near Southfields and the All England Club. The housing stock across SW18 is predominantly Victorian and Edwardian terraced houses — many of which have been substantially extended and modernised — alongside newer developments around the Wandsworth riverside and the Ram Quarter regeneration.
Heat-Plex is a trusted heating contractor across all parts of SW18. In the Victorian terraces of Earlsfield — the streets between Garratt Lane and Magdalen Road — we regularly replace ageing boilers, upgrade radiators, and install smart heating controls. These properties often have a specific layout: front and rear reception rooms, a narrow galley kitchen, and bedrooms above, with the boiler typically squeezed into a kitchen cupboard or an undersized utility area. Our engineers are adept at fitting modern compact boilers into these spaces and running pipework efficiently through the existing structure.
Southfields has a slightly different character, with wider semi-detached houses and some detached family homes. These larger properties often need system boilers with unvented cylinders to supply adequate hot water to multiple bathrooms. We design and install complete heating systems for these homes, including multi-zone controls and underfloor heating for ground-floor extensions — a particularly popular upgrade in SW18.
For the new-build apartments at the Ram Quarter, Wandsworth Riverside, and the developments along Armoury Way, Heat-Plex provides HIU servicing, underfloor heating maintenance, and emergency plumbing. We also serve Wandsworth's landlords with gas safety certificates and portfolio maintenance plans. With Wandsworth Town station providing quick rail links to Waterloo and our engineers based locally, we offer some of the fastest response times in the area.
Wandsworth features Victorian and Edwardian terraced houses across Earlsfield and Wandsworth Town, larger semi-detached homes near Southfields, and modern apartment developments at the Ram Quarter and Wandsworth Riverside. Many Victorian terraces have been extended with loft conversions and rear extensions, adding demands to existing heating systems.
The Victorian terraces of Earlsfield and Wandsworth Town often have heating systems that struggle to cope with rear extensions and loft conversions added without upgrading the boiler. Microbore pipework — common in 1970s and 1980s retrofit installations — restricts flow and causes cold radiators on upper floors. In the semi-detached homes near Southfields, large properties with multiple bathrooms need careful system design to ensure sufficient hot water pressure.

“We extended our Earlsfield terrace and needed the entire heating system redesigned. Heat-Plex installed a new system boiler, added radiators to the extension and loft, and set up smart zones so we can heat each floor independently. Excellent work — tidy, on time, and fairly priced.”
Wandsworth is well connected via Wandsworth Town and Earlsfield stations (both on the South Western Railway to Waterloo) and East Putney and Southfields on the District Line. Heat-Plex engineers know the area's parking zones around Garratt Lane and the Southfields grid, and we maintain working relationships with local letting agents along Wandsworth High Street.
