Merton spans the period conversions and Victorian villas of Wimbledon and Wimbledon Park, the larger family homes of Raynes Park and Morden, and the denser terraces of Mitcham and Colliers Wood. Each brings a different heating challenge.
Compact combi boilers and sealed pressurised systems serve the flats converted from larger period houses. Smart thermostat setup and diagnostics behind sealed pipework are common jobs here.
Larger properties typically need higher-output boilers and well-balanced multi-radiator systems. Boiler upgrades, power flushing and full system rebalancing are frequent requests here.
Older conventional systems are still common in these terraces. Like-for-like upgrades, system-to-combi conversions and radiator replacements that respect original pipework are particularly common here.
Extending the existing heating system into a new loft room or rear extension needs careful sizing and pipe routing, which we plan in as part of the installation.
New combi, system or conventional heating installed from scratch — free survey, all major brands, old system removed free of charge.

Our system in Morden never balanced properly and a couple of rooms never got warm. The engineer rebalanced everything and fitted thermostatic valves where they were missing — every room now actually reaches the temperature we set.
Old conventional system in our Mitcham house that needed converting without disturbing the original pipework. Talked us through every option before starting, and the finished job looks like it was always meant to be there.
Converted flat in Wimbledon with a boiler that kept losing pressure. Found a hairline crack in the expansion vessel within minutes, replaced it, and it’s been steady ever since.
