Boiler repair in Truro
We repair gas, oil and LPG boilers across Truro. 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 Truro is its own job
Truro is the county's commercial centre and the place most of Cornwall passes through, so it is where we are based and where we can usually get to you quickest. The city packs an unusual amount of variety into a small area: Georgian merchant houses on Lemon Street, flats carved out of the floors above the shops on Boscawen Street, and sprawling modern estates out at Threemilestone and Highertown.
The property here
Central Truro is dominated by Georgian and Victorian townhouses, a great many of them listed or in the conservation area, and a large number since divided into flats and offices. Original pipework runs in awkward places and rarely where the drawings suggest. Out at Highertown, Threemilestone and Gloweth the stock flips to post-war and modern estate housing with conventional layouts and, increasingly, first-generation combis now old enough to need replacing.
What catches people out in Truro
The city-centre flat conversions are the ones that catch people out. A leak on a second-floor bathroom above a shop does not stay a second-floor problem — it becomes three businesses' problem within the hour, and access has to be arranged with people who are trading. We plan those jobs around the building rather than just the flat. Truro also sits where the Kenwyn and the Allen meet before the tidal Truro River, so the lower-lying parts of the city have a genuine history of water where it shouldn't be.
Boiler repair in Truro — what actually matters
Boilers in flats and conversions
Conversions put boilers in cupboards, hallways and roof spaces that were never intended to hold one, which affects both ventilation and how safely the thing can be worked on. Where the flue runs through a shared part of the building, the repair sometimes needs the freeholder as well as you.
Repairs in listed property
When an appliance in a listed building fails beyond repair, replacing like for like is not always possible and the flue is usually the sticking point. Worth knowing at the point of the repair rather than discovering it when the boiler finally dies.
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.
Old system, newer boiler
A common pattern here is a modern condensing boiler that was fitted onto a seventies system without cleaning it first. The boiler then gets blamed for faults that are really sludge and undersized pipework, and replacing it again will not fix them either.
What we cover
- Fault code diagnosis on all major brands
- No heating or no hot water
- Pressure loss and repeated refilling
- Leaks from the boiler or the system

- Diverter valves, pumps, PCBs, fans and heat exchangers
- 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 Truro
Truro is well served by mains gas across the city and the main suburbs, though outlying villages towards Chacewater and Shortlanesend can be a mixed picture.

Read moreBoiler repair in Truro — 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 Truro as well as the town?
Yes — Highertown, Threemilestone, Gloweth, Malpas, Kenwyn, Newbridge, Shortlanesend, Chacewater and Playing Place are all part of our normal Truro patch, along with the smaller places between them. If you are not sure whether we reach you, send the form and ask.

We are based on the Truro side of the county, so city callouts are typically the fastest response we offer.
