Fault Diagnosis
Common Boiler Faults We Fix
Most boiler breakdowns fall into a handful of categories. Here's what we see most regularly across Maidstone properties.
No heating or no hot water
Can be caused by a failed diverter valve (combi boilers), a faulty pump, a seized motorised valve, or a thermostat that's lost its settings. Often fixable on the same visit.
Low or lost pressure
A combi boiler needs to operate between 1 and 2 bar. Caused by a small system leak, faulty pressure relief valve, or the expansion vessel losing charge. We diagnose which one and fix accordingly.
Boiler won't ignite — error code showing
Common codes: Worcester Bosch EA222/EA227 (ignition failure), Vaillant F.28 (flame failure), Vaillant F.22 (low pressure), Baxi E168 (gas valve fault). Don't repeatedly reset — call us with the code so we can bring the right parts.
Leaking boiler
A dripping boiler may be a simple pump seal or pressure relief valve — both are straightforward to replace. A crack in the heat exchanger is more serious and in an older boiler often means repair cost approaches replacement cost.
Kettling or banging noises
Usually means limescale has built up on the heat exchanger. The Maidstone area has moderately hard water, making this a common issue in older boilers. Chemical descaling can help in mild cases.
Frozen condensate pipe
In very cold weather, the condensate pipe can freeze, causing the boiler to lock out. We can thaw the pipe and fit lagging to prevent recurrence.
Radiators not heating properly
Cold patches at the top indicate trapped air — bleed them. Cold patches throughout the radiator more likely indicate sludge build-up requiring a powerflush or chemical treatment.
Pilot light keeps going out
More common on older boilers with a standing pilot light. Usually a faulty thermocouple (relatively cheap to replace) but can also indicate a draught issue with the flue.

We Repair All Boiler Brands
We repair all mainstream boiler brands. For less common makes, parts are generally available on 24–48 hour delivery, so most repairs can be completed within 1–2 days.
When you call a specialist, diagnosis is faster, parts knowledge is deeper, and the chance of a correct first-visit fix is significantly higher than with a generalist plumber.
Honest Advice
Repair or Replace? An Honest Guide
We never push replacement unnecessarily — but we won't tell you a repair is the right answer when it isn't.
Repair almost always makes sense, unless the fault is a catastrophic component like the heat exchanger in a low-efficiency boiler.
Depends on the fault and cost. A repair under £200 on a 10-year-old boiler in good condition is usually worthwhile. £400+ on a 12-year-old with existing history is harder to justify.
General guidance: replace if the repair quote exceeds £300–400. An older boiler is significantly less efficient and another fault is likely within 1–2 years regardless.
We'll carry out the repair if requested, but at 20+ years any significant repair is difficult to recommend on financial grounds.

Our Process
How We Handle Your Repair
Diagnosis
We ask you to describe the symptoms before arrival so we can bring the most likely replacement parts. On arrival, we carry out a systematic diagnosis — we don't replace parts speculatively.
Confirmed Quote
Before touching anything, we tell you what we've found, what's needed to fix it, and the exact cost. You decide whether to proceed.
Repair
Where parts are on the van, we fix it there and then. Where a part needs ordering, we confirm expected delivery and return to complete the job.
Test & Sign-Off
After every repair, we test the boiler fully — including heating, hot water, and all safety cut-offs — before confirming the work is complete.
