Boiler Installation & Servicing Cornwall

We install new heating systems, service existing ones under contract, and diagnose systems that have never heated the property properly. Gas, oil and solid fuel, all registered in the same business, so the recommendation is based on the building rather than on what we happen to be certificated for.

Common questions

Before you call

How much does a boiler installation cost in Cornwall?

A like-for-like gas swap sits at the bottom of the range. Moving the boiler, changing fuel type or fitting a system boiler with a new cylinder sits at the top. Oil installations vary again depending on the tank. We survey and give you a price.

How long does a boiler installation take?

One day for a straight swap in the same position. Two to three days if the boiler moves, the fuel changes or a cylinder goes in. We tell you which before starting.

Do you cover oil boilers as well as gas?

Yes, we are OFTEC registered as well as Gas Safe, which matters in Cornwall where a large number of properties are off the gas grid.

How often should a boiler be serviced?

Once a year, and every manufacturer warranty depends on it. Landlords need an annual gas safety check as a legal requirement, which is a different thing from a service, though we usually do both in one visit.

What is power flushing and do I need it?

Power flushing clears sludge and corrosion debris out of the system. You need it when radiators are cold at the bottom, the boiler is noisy, or the system takes an age to warm up. A new boiler fitted onto a dirty system will not last as it should, so flushing is part of the installation.

Where do I get a landlord gas safety certificate in Cornwall?

From any Gas Safe registered engineer, and we issue CP12 certificates across Cornwall and Devon. Multiple properties can go on one annual schedule so the renewal dates do not drift.

What does a heating engineer do that a plumber does not?

Heating work needs a Gas Safe or OFTEC registration on top of plumbing skill, because it involves combustion, flues and fuel rather than water alone. Our heating engineers hold both, so a job that is part plumbing and part heating is one visit.

My heating has never worked properly, can you find out why?

That is a diagnostics job rather than a repair. Usually it is pipe sizing, pump position, a bypass that was never fitted or radiators that were never balanced. We test the system before replacing parts.
