- Central heating
- Hiring tradespeople
Boilers should be serviced every year so friends, family and neighbours should be able to recommend a boiler engineer they have used.
Use Which? Trusted Traders to find boiler, gas and central heating engineers in your area or to see if those already recommended to you have been endorsed and reviewed.
Central heating engineers must be Gas Safe Register-accredited. The Gas Safe Register is the official gas registration body for the United Kingdom, Isle of Man and Guernsey (replacing CORGI).
All Which? Trusted Traders are on the Gas Safe Register but, whenever you hire any gas engineer, you should check what type of gas-related work they are qualified to undertake before hiring them.
If you’re calling about a broken-down boiler, tell the engineer about the nature of the problem and any error messages showing on your boiler’s display. They’ll be able to tell you about the price for a call-out but additional costs depend on the nature of the problem and any parts required. You might also be charged for travel and parking costs.
If you need a new central heating system or servicing on your existing set-up, you’re in a better position to do more research and contact several engineers for quotes.
Call at least three boiler engineers. You could ask:
Good central heating engineers will usually want to see your system before they give you a quote for anything other than a simple job.
Inviting prospective boiler engineers to visit should give you a feel for whether they can be trusted. For example, do they explain your options clearly and without jargon or are you being bamboozled with technical terms and pressurised into costly work.
If you’re getting a new boiler or central heating system installed, the engineer should be looking around your home and asking about your lifestyle in order to determine what the best and most efficient system would be.
Whatever work is required, you should get detailed written quotes so that you can compare the proposed solutions and prices. Call the engineers about any questions that arise after they’ve visited – good engineers are always happy to help.
If your job includes supply and installation of a new boiler or other significant work, you might reasonably be expected to pay an instalment before the work begins. New boilers and radiators can cost thousands of pounds, so don’t baulk if the initial instalment seems high but make sure you have agreed how and when additional payments will be made.
The best boiler engineers explain what they’ll check, repair or install before they start working and show you what they’ve done afterwards.
When the work is complete, you should check that the boiler is operating as expected – check both the hot water and heating. Make sure the engineer shows you how to use the settings on a new boiler or thermostat, as well as any other central heating system controls.
