Boiler repair in Cornwall
A boiler repair should start with finding out what is actually wrong. Too much of this trade replaces the part that is easiest to reach, and the customer pays twice when the real fault surfaces again a fortnight later.

Signs you need us
Pressure keeps dropping
If you are topping up more than once or twice a year there is a leak, or the expansion vessel has lost its charge. Repeatedly refilling is treating the symptom and quietly corroding the system with fresh oxygenated water.
Hot water but no heating (or vice versa)
That split is the classic diverter valve signature. It is a common, well-understood repair and rarely a reason to replace a boiler.
Kettling — a rumble like a kettle
Usually scale or sludge in the heat exchanger restricting flow. Worth acting on: it shortens the life of the most expensive component in the appliance.
It locks out and needs resetting
A reset that works is a warning, not a fix. A boiler that needs resetting repeatedly is telling you something is wrong and will eventually stop resetting.
How it works
- 1
Diagnosis
Full fault-find, including checking the things the fault code does not cover — gas pressure, flow rates, system water quality.
- 2
An honest repair-or-replace answer
If your boiler is old and the repair is uneconomic we will say so, and if it has years left we will say that too, even though the replacement is the bigger job for us.
- 3
You approve the cost
Parts and labour agreed before we order anything.
- 4
Repair and test
Repaired, tested under load, and combustion checked before we sign it off.
What it costs
Diagnosis is charged separately from the repair, and we tell you the diagnosis cost before we come out. If we cannot fix it, you are not paying for a repair that did not happen.

Read moreBoiler repair — your questions
If yours is not here, send us the form and ask. We would rather spend five minutes answering a question than have you book something you did not need.
Is it worth repairing or should I replace it?
Broadly: if the repair costs a significant fraction of a new boiler and the appliance is past its designed life, replacement usually wins. But an eight-year-old boiler needing a common part is worth fixing, and we will tell you which situation you are in.
Do you repair oil boilers as well as gas?
Oil is a large part of rural Cornwall and we treat it as core work, not an afterthought — the accreditation for it is separate from Gas Safe and it is listed on our accreditations.
How long do parts take to arrive?
Common parts for the major brands we carry or can get next day. Obscure parts for discontinued models are the ones that take time, and we will tell you at diagnosis if yours is likely to be one.
Will a repair void my manufacturer warranty?
Not if it is carried out by a suitably registered engineer and documented, which is how we do it. Keep the paperwork we give you.
