Boiler Installation & Replacement

Age, fault history and part availability decide it. A boiler under roughly eight years old with a single fixable fault is usually worth repairing. Frequent breakdowns, an obsolete part, or a boiler clearly mismatched to the property's demand point towards replacement. We assess this honestly during any call-out rather than assuming replacement is the answer.

Often yes, where hot water demand suits it, but it means removing the cylinder and tank and reworking pipework, which adds cost and disruption beyond a straight swap. We assess this at survey stage against your actual hot water usage before recommending a conversion.

No. An oversized boiler short-cycles — switching on and off more frequently than needed — which wastes energy and shortens component life. Correct sizing from a heat loss calculation gives steadier running and better efficiency than simply choosing a higher kW rating.

Yes. Commissioning includes completing the Benchmark logbook and registering the installation with the manufacturer, which is usually a condition of the extended warranty. We also notify Building Control through the Gas Safe scheme as required.

It depends on the scope — a straightforward like-for-like combi swap is quicker than a conversion between boiler types or a full system clean. We confirm timescale at survey stage once the actual work involved is known.

We remove and dispose of the old boiler responsibly. If the existing pipework or radiators show contamination, we recommend a power flush and filter as part of the installation to protect the new boiler's warranty and performance.

Ongoing annual servicing is available separately once your new boiler is in — see Boiler Servicing for what that includes and why it matters for warranty validity.
