Boiler repair in St Ives
We repair gas, oil and LPG boilers across St Ives. 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 St Ives is its own job
St Ives is the hardest town on this list to work in, and any plumber who tells you otherwise has not tried to get a bathroom suite into Downalong in August. It is also one of the most rewarding — beautiful granite property, a huge amount of high-end refurbishment work, and owners who care about the job being done properly.
The property here
The old quarter, Downalong, is a dense maze of granite fishermen's cottages on lanes measured in feet rather than metres. Above it, Victorian and Edwardian terraces climb the hill, and out at Carbis Bay and Lelant you find larger detached property and a good deal of recent high-specification renovation.
What catches people out in St Ives
Access defines everything here. Much of Downalong cannot take a van at all, so kit and materials come in by hand and the job has to be planned properly in advance — you cannot nip back to the merchant for a fitting. We order and stage materials before we start rather than discovering the problem on day one. On top of that, the granite cottages have thick solid walls, minimal plant space and no obvious route for a flue, and a very high proportion of the town is second homes and holiday lets, which means unoccupied properties where a small leak has weeks to become a large one.
Boiler repair in St Ives — what actually matters
Repairs where the van cannot park
If we cannot get the van to the door, we bring what we can carry — so an accurate description on the phone is worth a great deal. The better we understand the fault before setting off, the better the chance we have the part with us.
Diagnosing an appliance you cannot see
If you are not in the county we will photograph the fault, the readings and the appliance data plate, and explain the repair-or-replace decision properly. Nobody should be approving a spend of several hundred pounds on the strength of a phone call and a fault code.
Solid-wall property
Where the boiler is fighting a house with no insulation in the walls, it runs harder and for longer than it was designed to, and it wears accordingly. If yours is failing early, the building is often as much the cause as the appliance.
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.
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
- Lockouts, ignition failure and flame loss
- Noisy operation, kettling and banging
- 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 St Ives
St Ives and Carbis Bay have mains gas in most of the built-up area, but running a new supply into the older parts of Downalong is rarely straightforward.

Read moreBoiler repair in St Ives — 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 St Ives as well as the town?
Yes — Carbis Bay, Lelant, Halsetown, Zennor, Towednack, Porthmeor and Downalong are all part of our normal St Ives 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 St Ives?
In via Lelant off the A30. Summer access into the town is genuinely difficult and we plan around it rather than over-promising.
