Boiler fault finding in Kingston upon Thames for problems nobody has managed to pin down. We test the gas, water and electrics in a set order until the cause shows itself, then explain it before doing any work.
We work through the system in order: gas pressure at the meter and the appliance, water pressure and flow, then the electrical side. Testing in sequence rules causes out one at a time instead of jumping to the part that fails most often.
More Information
Plenty of call outs turn out to be a thermostat, a wiring centre, a seized zone valve or a blocked condensate pipe. The boiler gets the blame because it is the thing that stopped. Checking the whole system avoids replacing a working boiler.
When we find the cause we tell you what it is, what caused it and what the options are, in plain terms. If there is a cheaper route that will hold for a season and a more permanent fix, you get both and choose.

Intermittent faults usually point to a component failing when hot, a loose electrical connection, or a condensate pipe that freezes or blocks in cold weather. It needs testing while the fault is present, so tell us when it tends to happen.
We charge for the diagnostic visit and tell you the rate before booking. If the fault turns out to be something we can repair on the spot, the diagnosis time forms part of the job rather than being charged twice.
Often, yes. A fresh approach and a methodical test sequence catch things that get missed when a fault is assumed rather than proven. Tell us what has already been replaced so we can start from what is known rather than from the beginning.
