Plumbers or heating engineers: who do I need?

Wondering whether to hire a plumber or a heating engineer? You’re not alone. Plumbers and heating engineers are professionals who work with different systems in a building. They’re hired during the final phases of construction and for the general maintenance of residential homes.

While the roles of a plumber and a heating engineer may seem similar, they actually have distinct specialisms and responsibilities.

Here’s how to work out who you need to call for your job.

The difference between a plumber and a heating engineer

When to hire a plumber (not a heating engineer)

Plumbers primarily deal with the installation, repair, and maintenance of pipes, fixtures, and other equipment used to distribute water and remove wastewater.

They are skilled in working with different types of materials, including copper, PVC, and cast iron. They also have knowledge of local building codes and regulations related to plumbing.

Hire a plumber for tasks such as:

• Installing, repairing, and maintaining the pipes and fixtures that carry water and waste in a building
• Installing and repairing plumbing systems in new constructions (e.g. toilets, showers, baths and sinks etc.)
• Repairing and replacing pipes and fixtures
• Unclogging and cleaning drains
• Plumbers may also install and repair gas lines and appliances, such as water heaters and boilers
