Boiler installation in Penzance
We install and replace boilers throughout Penzance. 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 Penzance is its own job
Penzance sits at the head of Mount's Bay looking south-west into whatever the Atlantic sends, and that single fact shapes more of the heating work here than anything else. It is a handsome town — Georgian and Regency along Chapel Street, subtropical planting at Morrab Gardens — with a working fishing port next door at Newlyn and a large rural hinterland out through west Penwith.
The property here
Georgian and Regency townhouses in the centre, a good many of them listed, Victorian terraces spreading out from the station, and then granite cottages and smallholdings scattered across west Penwith towards Mousehole, St Buryan, Sennen and Zennor.
What catches people out in Penzance
Nothing on this list weathers like Penzance. Salt-laden onshore wind eats flue terminals, external condensate pipes and any exposed copper, and installations that would last twenty years inland need siting and specifying far more carefully here. Get further out into west Penwith and the second issue takes over: much of it has no mains gas at all, so it is oil, bulk LPG or increasingly heat pumps — which needs OFTEC and LPG competence rather than just a Gas Safe card.
Boiler installation in Penzance — what actually matters
Specifying for salt exposure
On an exposed coastal plot, flue terminal position, condensate routing and the choice of external materials matter far more than they would inland. Getting that right at installation is the difference between a boiler that lasts its life and one that corrodes early.
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.
Flues in listed property
Flue routing in a listed building is a planning question as well as a technical one, and the obvious external position is frequently not permissible. We work that out before quoting, not on installation day.
Sizing for solid granite walls
A granite cottage with no cavity loses heat at a rate that standard assumptions badly underestimate. Size the boiler and radiators to the actual fabric and the house is warm; size it to a table and the occupant spends fifteen years wondering why it never quite gets there.

- Room-by-room heat loss calculation before specification
- Back boiler removal and conversion
- Oil and LPG boiler installation as well as mains gas
- Unvented hot water cylinder installation
- System flushing and filter fitting as standard
- Building control notification and warranty registration
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 Penzance
Penzance, Newlyn and Heamoor are largely on mains gas. West Penwith beyond that is substantially off-grid — expect oil, bulk LPG or a heat pump conversation rather than a gas one.

Read moreBoiler installation in Penzance — 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 Penzance as well as the town?
Yes — Newlyn, Mousehole, Marazion, Heamoor, Gulval, Long Rock, St Buryan, Sennen and Pendeen are all part of our normal Penzance 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 Penzance?
The far end of the A30. It is a real drive from mid-Cornwall, so we are honest about arrival windows here rather than quoting an optimistic number.
Can you help if my property has no mains gas?
Penzance, Newlyn and Heamoor are largely on mains gas. West Penwith beyond that is substantially off-grid — expect oil, bulk LPG or a heat pump conversation rather than a gas one.
