Common Questions — Central Heating Repair in Merton

Why are my radiators cold in Merton?

Cold radiators in Merton are most commonly caused by sludge build-up (fixed by bleeding or power flushing), a faulty pump, an air-locked system, or a failed zone valve. We diagnose on the same visit and fix the root cause — not just the symptom.

My boiler pressure keeps dropping in Merton. Why?

Recurring pressure loss in Merton is almost always caused by a leak — either in the pipework, a leaking radiator valve, or a failing expansion vessel. We test the system under pressure, find the leak point and repair it.

Can you repair my heating in Merton today?

Yes. We operate 24/7 across Merton and carry common heating parts — pumps, zone valves, pressure vessels and thermostats. Most faults are diagnosed and repaired in a single visit.
