Essential checks when hiring a heating engineer

Verify Gas Safe registration

Every engineer carrying out gas work must be on the Gas Safe Register. Ask to see their Gas Safe ID card and verify the registration number at gassaferegister.co.uk before work starts.

Check they are qualified for your boiler brand

Some boiler manufacturers require their warranty to be maintained by engineers certified for that brand (e.g. Worcester Bosch Accredited Installer). Ask before booking.

Ask about boiler warranties

New boiler installations should come with a manufacturer's warranty. Confirm the duration (typically 5–12 years depending on brand and installer accreditation) and what it covers.

Heating engineer FAQs

Your boiler should be serviced by a Gas Safe registered engineer every year. Regular servicing keeps the boiler running efficiently, can identify small issues before they become expensive problems, and is usually required to maintain the manufacturer's warranty.

A combi (combination) boiler provides both heating and hot water on demand without the need for a hot water storage cylinder or cold water tank. A system boiler heats water that is stored in a cylinder — better for homes with multiple bathrooms or higher hot water demand. The right choice depends on your property's size and usage patterns.

No. It is illegal for anyone who is not Gas Safe registered to carry out any gas work on gas appliances, pipework or flues in the UK. This includes connecting appliances, moving gas pipes and servicing boilers. Only a registered Gas Safe engineer can legally carry out this work.
