Boiler installation in St Austell
We install and replace boilers throughout St Austell. The important part happens before anything is fitted: working out what output the house actually needs, whether the existing pipework and radiators can carry it, and what the flue can lawfully do.

Why boiler installation in St Austell is its own job
St Austell grew on china clay, and the town and the villages ringing it were largely built to house the people who worked it. That history shows up directly in the plumbing: this is the biggest concentration of mid-twentieth-century housing in the county, much of it now reaching the point where the original heating system has simply come to the end of its life.
The property here
Post-war and 1960s–70s estate housing dominates, alongside the older clay-village terraces at Bugle, Roche, Stenalees and Foxhole and the very different Georgian and Regency stock down at Charlestown and out towards Carlyon Bay and Fowey.
What catches people out in St Austell
A great deal of our St Austell work is first-generation central heating replacement — systems put in during the seventies and eighties, running on undersized microbore, with sludged radiators and a boiler that has been nursed along for a decade. Replacing the boiler alone on a system like that is money badly spent; it will fail early and the warranty will not cover it. A proper power flush and, where the pipework demands it, partial re-piping is what makes the new appliance actually last.
Boiler installation in St Austell — what actually matters
Replacing first-generation central heating
Where the original system dates from the seventies or eighties, the pipework is often undersized microbore and the radiators are full of sludge. Fitting a modern condensing boiler onto that without addressing it will void the warranty and kill the appliance early.
Replacements in terraced houses
Moving a boiler in a terrace is often the right call — out of the kitchen, shorter flue, better pipe routes — and it is nearly always the option nobody mentions. It costs more on the day and pays back in efficiency and in never having to work around it again.
Oil, LPG and the heat pump question
With no mains gas the decision is genuinely open, and it is worth taking seriously rather than replacing oil with oil by default. We will model the realistic options for your property, including what your building fabric would need for a heat pump to actually work.
Town supply, rural reality
The same town can have mains gas in the centre and none at all four miles out, so the right answer for your neighbour may be the wrong one for you. We survey the property in front of us rather than assuming what the area does.

How it works
- 1
Survey — in person
We look at the house, the pipework, the radiators, the flue route and the gas supply. A boiler cannot be specified properly from a web form and we do not pretend otherwise.
- 2
Heat loss calculation
Room by room, so the boiler and the radiators are sized to the building. This is the step that gets skipped, and it is the step that determines your running costs for the next fifteen years.
- 3
A fixed written quote
Itemised, with the appliance named and the warranty stated. No pressure, and it stays valid long enough for you to think about it.
- 4
Installation
Typically one to two days for a straight replacement, longer for a conversion. Dust sheets, and the heating back on the same evening wherever possible.
- 5
Handover and registration
We commission it, show you how it works, register the warranty and notify building control. You get the paperwork before we leave.
What it costs
Every installation is quoted individually after a survey, at a fixed price. We do not publish a price list for boilers because a number without a survey behind it is a number that changes on the day — which is precisely the practice that gives this trade its reputation.
Mains gas in St Austell
The town has reasonable mains gas coverage, but the outlying clay villages are noticeably patchier — oil and LPG are common once you get up towards Bugle and Roche.

Read moreBoiler installation in St Austell — 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.
How long does a boiler installation take?
A straightforward like-for-like swap is usually a day, sometimes two. Moving the boiler, converting from a back boiler, or changing system type takes longer and we will tell you honestly at quote stage.
Do I need a magnetic filter?
Yes, and we fit one as standard. Most manufacturer warranties now require one, and it is the cheapest thing you can do to protect the heat exchanger.
Should I switch to a combi?
Not always. Combis suit smaller properties with one bathroom and good mains pressure. If you have two bathrooms, poor incoming pressure or several people showering at once, a system boiler and cylinder is usually the better answer — and plenty of firms will sell you the combi anyway.
What about a heat pump instead?
For an off-grid property currently on oil or LPG, a heat pump is genuinely worth modelling. For a solid-walled granite cottage with no insulation, it usually is not, yet. We will give you a straight answer rather than a sales pitch either way.
Do you cover the villages around St Austell as well as the town?
Yes — Charlestown, Carlyon Bay, Par, Bugle, Roche, Stenalees, Trewoon, Boscoppa, Pentewan and Mevagissey are all part of our normal St Austell 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 Austell?
Straight down the A390 from Truro, or off the A30 via the Innis Downs junction.
Can you help if my property has no mains gas?
The town has reasonable mains gas coverage, but the outlying clay villages are noticeably patchier — oil and LPG are common once you get up towards Bugle and Roche.
