Central Heating Service in London
Every radiator warm, the whole system efficient
A central heating service in London looks after the whole system, not just the boiler. Our Gas Safe registered engineers check your radiators, pipework, pump, valves, controls and magnetic filter, then bleed and balance the system so every room warms up evenly. It is ideal if some radiators are cold at the top, the pressure keeps dropping or the heating takes too long to warm up. For the boiler itself, add a boiler service to the same visit, or see our other heating services.

How we service your heating system
- System check: We run the heating and check every radiator, the pump, the valves and the visible pipework for cold spots, noise, leaks and corrosion.
- Water quality: We test the inhibitor level, clean the magnetic filter and top up the inhibitor where needed to protect the system from sludge and rust.
- Bleed, balance and pressure: We bleed trapped air, balance the radiators so each room heats evenly, set the correct system pressure and check your thermostat and programmer.
Why service the whole system?
Your boiler can be in perfect order and your home still feel cold if the system around it is struggling. Air, sludge and badly balanced radiators make the boiler work harder, push up running costs and wear out the pump and valves sooner. A yearly central heating service keeps the water clean and the heat spread evenly around your home. If our checks find heavy sludge in the system, we may recommend powerflushing to clean it out properly.
