Plumbing advice
Do I Need a Plumber or a Gas Engineer?
Understand who to call for a leaking tap, a heating problem or a gas boiler fault, and when to use the gas emergency service.
The right person depends on the equipment and the work involved. Some plumbers are also qualified gas engineers, but a business offering general plumbing does not automatically have the credentials for gas work. Explain the problem before booking.
Start with the affected equipment
For a leaking tap, toilet repair or a fault in ordinary water pipework, ask a plumber whether they handle that type of job. For a gas boiler repair or service, you need a Gas Safe registered engineer with the relevant qualifications.
The HSE distinguishes heating-system water work from work on a gas boiler. Even a job that looks water-related may involve the boiler itself or connections that require a gas engineer. Let the contractor establish the boundary before work starts.
Oil boilers, heat pumps and electric heating need different expertise. Tell the business what system you have, rather than requesting a generic boiler visit and hoping the person attending covers it.
Check the person and the proposed visit
Before gas work begins, inspect the engineer’s current Gas Safe ID and confirm the relevant work categories. NI Direct explains what to check on the card, including identity, dates and qualifications. Verify registration through the official Gas Safe Register.
When calling, have the make and model, a visible fault code and a brief description ready. Say whether you have heating, hot water, both or neither. Photograph the display from outside the appliance if that helps, but do not remove its cover.
Ask what the diagnostic charge covers and whether a separate return visit may be needed. If water is actively leaking, say so at the start of the call.
Treat gas concerns as an emergency
If you smell gas or suspect a gas leak, avoid flames and electrical switches, leave for a safe place and call the emergency service. Do not wait for a routine directory enquiry.
For Great Britain, call 0800 111 999. In Northern Ireland, call 0800 002 001. If a carbon monoxide alarm sounds, leave immediately and call the relevant emergency number. Seek urgent medical advice if anyone may have been exposed; call 999 for immediate danger or serious illness.
For a non-emergency job, find local plumbing businesses or browse heating services. Confirm the attending engineer’s qualifications directly; a service listing does not establish Gas Safe registration.
