Boiler repair in Falmouth
We repair gas, oil and LPG boilers across Falmouth. Whatever the fault code says, we diagnose properly before quoting parts — the code tells you where the boiler noticed a problem, not always where the problem is.

Why boiler repair in Falmouth is its own job
Falmouth runs down a series of steep hills to one of the deepest natural harbours in the world, and the town has two quite separate plumbing economies going on at once. There is the resident and marine trade around the docks and Penryn, and there is the enormous student and holiday rental market that the university has built up over the past twenty years.
The property here
Victorian and Edwardian terraces make up much of the town, a very large share of them now converted to shared houses and flats. Many are three and four storeys, built into the hillside, with the bathroom at the top and the boiler somewhere improbable. Out towards Mylor, Flushing and Maenporth you get detached and coastal property with a different set of problems again.
What catches people out in Falmouth
Two things define Falmouth work. First, the shared houses: a combi sized for a family simply cannot supply six students who all want a shower between eight and nine, and we spend a lot of time correcting undersized systems and issuing landlord gas safety certificates to deadline. Second, the salt. Properties facing the water lose flue terminals, external condensate runs and exposed copper years earlier than an inland equivalent, and it is worth siting new work with that in mind rather than discovering it in five years.
Boiler repair in Falmouth — what actually matters
Shared houses
A boiler serving a six-bed shared house does several times the duty cycle of a family home and fails on that schedule. Repairs here need to consider whether the appliance was ever the right size for the demand.
What salt air does to a boiler
Exposed coastal properties corrode flue terminals and external condensate pipework years earlier than inland equivalents, and salt drawn into the combustion air path shortens component life. It is a genuine local factor in why a boiler here fails sooner, and it is worth specifying for at replacement.
Terraced houses
Boilers in these houses are usually in the kitchen at the back with a long flue run and pipework threaded through original floors. Access is the first half of the job, and it is the half that gets underestimated when a price is given over the phone without seeing it.
Damp and marine air
Persistent damp in older harbourside buildings corrodes casings, electrics and condensate traps from the outside in. When we find early corrosion we say so, because it changes how long the appliance realistically has left.

- Oil and LPG appliance repair as well as mains gas
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.
Mains gas in Falmouth
Falmouth and Penryn have good mains gas coverage; the outlying villages towards Constantine and Mawnan Smith are more variable.

Read moreBoiler repair in Falmouth — 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.
Do you cover the villages around Falmouth as well as the town?
Yes — Penryn, Flushing, Mylor Bridge, Budock Water, Swanpool, Maenporth, Constantine and Mabe Burnthouse are all part of our normal Falmouth patch, along with the smaller places between them. If you are not sure whether we reach you, send the form and ask.
How quickly can you get to Falmouth?
A straightforward run down from Truro on the A39. Parking in the town centre is the constraint, not the distance.
