Radiators, controls & powerflushing
The service
The whole system, not just the boiler.
When the heating's not right it's rarely just the boiler. Cold spots, radiators warm at the top and cold at the bottom, banging pipes and high bills usually point to sludge, trapped air, a tired pump, or controls that were never set up properly. We look at the whole system and fix the actual cause.
We also upgrade controls, including smart thermostats, powerflush systems that have filled with sludge, and repipe runs that have corroded or started to leak, so your heating responds quickly and runs efficiently.
- Cold & patchy radiators: balanced, bled and flowing evenly
- Powerflushing & descaling: sludge cleared so heat returns
- Pumps, valves & controls: failed parts replaced and tested
- Smart thermostats: modern controls fitted and set up

Powerflush: when sludge is the problem
Years of circulating water leave sludge and rust inside radiators and pipework. It blocks flow, creates cold spots and makes the boiler work harder. A powerflush clears it out, often transforming a tired system for a fraction of the cost of replacement.
We'll tell you honestly whether a flush, a few new parts, some fresh pipework or a controls upgrade is the right answer. Every job guaranteed.

Central Heating Repair, the questions we get asked most.
That's the classic sign of sludge build-up. The cold area is where debris has settled and blocked flow. Bleeding helps if it's cold at the top (trapped air), but cold at the bottom usually means the system needs a flush.
