Central heating is one system with many parts: the boiler, the pump, the pipework, the radiators and the controls. A fault in any of them shows up as cold rooms, uneven heat or a gas bill that climbs for no obvious reason. MK Heating repairs, upgrades and installs central heating across East London, from a single cold radiator to a full system replacement, with Gas Safe engineers and written quotes before work starts.
Central heating repairs
Cold radiators at the top mean air. Cold in the middle usually means sludge. Radiators that never warm up point to a stuck valve or a balancing problem, and rooms that lag behind the rest of the house often trace back to the pump, a motorised valve or air locked in the pipework.
We diagnose the system as a whole rather than swapping parts hopefully, then quote for the fix in writing. Where the system water is dirty and the same fault keeps returning, we will suggest apower flush instead of letting sludge undo the repair.
New central heating and system upgrades
When a system needs more than a repair, we plan the job properly: boiler output matched to the property, pipework sized for the radiators it has to feed, and controls that suit how you actually live. That covers everything from replacing an old boiler like-for-like to installing central heating in a renovation. Ourboiler installation page explains the boiler types and what installation day involves.
Controls, thermostats and smarter heating
Old controls waste heat. A programmer, a room thermostat and thermostatic radiator valves let different parts of the house run on their own schedule. A smart thermostat goes further: it learns how long your home takes to warm up and can be adjusted from your phone when plans change.
Better control is one of the few upgrades that cuts gas use and improves comfort at the same time, and it often needs only a short visit. We supply and fit smart thermostatsand talk you through using them before we leave.
Radiators and balancing
Radiators that need bleeding every few weeks are telling you something: air is getting in, or the system water is corroding from inside. We repair and replace radiators, size new ones properly for the room, and balance the system so heat spreads evenly instead of the nearest radiator cooking the hallway while the back bedroom stays cold.
Getting more from the system you already have
Not every improvement costs much. Lowering the flow temperature on a modern condensing boiler makes it burn gas more efficiently, and many are installed running hotter than they need to be. Bleeding and balancing radiators evens out cold spots. An annual boiler service keeps the boiler working at the efficiency it was built for. Even a dripping hot tap is heated water going straight down the drain.

Frequently asked questions
Why are some of my radiators cold?
Cold at the top means trapped air, which bleeding usually clears. Cold in the middle or bottom points to sludge in the radiator. Radiators that stay cold altogether suggest a valve, balancing or pump problem. We find which one applies and quote for the fix.
Do you repair central heating systems as well as boilers?
Yes. The boiler is one part of the system, and we diagnose the whole thing: pumps, motorised valves, pipework, cylinders, radiators and controls.
Is a power flush worth it?
When the system water is dirty, yes. Sludge blocks radiators and stresses the pump and boiler. We test the water and check the symptoms first, because not every fault is caused by sludge, and we only recommend a flush when it will actually help.
Will a smart thermostat save me money?
Better control usually cuts gas use, because the heating runs only when and where it is needed. The exact saving depends on the house and how you use it, so we would rather fit good controls and let your bills show the difference than quote you a made-up percentage.
Can you install central heating in a property that has none?
Yes. We plan the full layout: boiler position, pipework runs, radiator sizes and controls, then quote the whole job in writing before work starts.
How often should central heating be serviced?
The boiler needs an annual service to stay safe and keep its warranty. The wider system is worth attention when symptoms appear: cold radiators, noisy pipework or pressure that keeps dropping.
