Questions and answers

If you have no heating or hot water we treat it as urgent and aim to fit within 24 to 48 hours of you accepting the quote. A standard swap takes a day; a conversion usually takes two.

No. Our quote tool gives you a guide price from a few questions. We survey before the work goes ahead so the final figure is confirmed in writing, but you do not need anyone in your house to find out roughly what it costs.

The boiler, the fit, a full system flush, cleaner and inhibitor, a magnetic filter, controls, the pipework the swap needs, removal of the old unit, all certificates and warranty registration.

Yes, for emergencies and by arrangement for commercial customers. Out-of-hours work is charged at a higher rate which we tell you before setting off.

Yes, including interest-free options. Subject to status and credit checks, arranged through Phoenix Financial Consultants.

Yes, by F-Gas qualified engineers. Single rooms from £1,850 and multi-room systems from £3,450. It heats as well as cools.
