Boiler installation in Cornwall
Most boiler replacements in this county are sized by looking at what was there before. That is how people end up with an oversized boiler that short-cycles, costs more to run and wears out early. We do the heat loss calculation.

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 We do not publish a price list for boilers because a number without a survey behind it is a number that changes on the day — which is precisely the practice that gives this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.

Read moreBoiler installation — 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.
