Boiler repair in Cwmbran
We are in the town, so a Cwmbran call-out is minutes away rather than an hour. Same-day, and we aim to be with you within two hours.
Call 07476 272447. Ring rather than email — from the fault code and two or three questions we can often tell whether it is something we can talk you through on the phone or something that needs a visit.
New boilers on old systems
This is the single most common story in Cwmbran. The estate houses were built with conventional heating, and most had a combi dropped in at some point since, often onto the original pipework and the original steel radiators. That combination produces its own set of faults: debris from old radiators finding its way into a modern plate heat exchanger, hot water that runs lukewarm no matter what the boiler is doing, and pressure that will not hold because the system was never properly cleaned when the new boiler went on.
A magnetic filter and a proper flush fixes more of these than a new part does, and we would rather tell you that than sell you a component that will be blocked again by next winter.
Frozen condensate
Worth knowing about because it looks like a dead boiler and usually is not. In a lot of houses here the boiler ended up where there was no drain, so the white condensate pipe runs the long way round the outside of the house to a gully at the back — exposed, and the first thing to freeze on a cold night. A locked-out boiler and a gurgling noise from that pipe is the giveaway. Warm water, not boiling, poured along it will normally bring the boiler back. If it happens every winter the pipe wants rerouting or lagging properly, which we can do.
Repair or replace
You get the honest number. A cracked heat exchanger on a fourteen-year-old boiler is not worth the money; the same boiler at six with a failed fan obviously is. We would rather lose a repair than take payment for one on something with a year left in it.
Parts on the van
We carry the common failures — sensors, pumps, diverter valves, pressure relief valves and expansion vessels — so most repairs are done in one visit. If something has to be ordered we will tell you when it lands rather than leaving you to chase it.

Frequently asked questions
How much should a boiler repair cost?
It comes down to the part, and parts range from a cheap sensor to a heat exchanger that costs more than the boiler is worth. We diagnose first and give you the part price and the labour before anything is fitted, so the decision stays yours. If the number does not make sense we will say so rather than quietly doing the work.
What is the average lifespan of a boiler?
Most gas boilers last somewhere between ten and fifteen years, and serviced ones sit at the top of that range. Water quality and system cleanliness make more difference than the badge on the front. A boiler running on an old, sludged system will not reach fifteen no matter what it cost.
Is it cheaper to repair or replace a boiler?
Repair is almost always cheaper today, and replacement is often cheaper over the next five years. The line falls roughly where a single repair costs a meaningful share of a new boiler on a unit that is already past ten. We will give you both numbers and the reasoning, and we are happy to fit the part if that is what you decide.
Is it worth fixing a 20 year old boiler?
Usually not, unless the fault is genuinely trivial. At twenty years the parts are getting hard to source, the efficiency is well behind anything current, and the next failure is rarely far behind this one. If it is a thermostat or a pump, mend it and plan ahead; if it is the heat exchanger, put the money towards a replacement.
What are the signs a boiler needs replacing?
Repeated breakdowns in one heating season, pressure that will not hold, rising running costs, and parts that are becoming difficult to get. Rumbling or kettling noises point at scale or sludge in the heat exchanger, which is often the beginning of the end. One fault on an otherwise reliable boiler is not a reason to replace it.
