 Plumbers vs. Heating Engineers: What is the Difference? 


Domestic plumbers and heating engineers are both skilled tradespeople who play vital roles in keeping our homes comfortable and functional. However, their areas of expertise and typical responsibilities differ. We have included a full breakdown in this article, if you are keen to learn more!

Domestic Plumber:

Focus: Primarily deals with water systems and drainage in homes.

Responsibilities include:

  • Installing and repairing toilets, sinks, faucets, showers, bathtubs, dishwashers, washing machines, and other water-using appliances
  • Water pipes and drainage systems
  • Fixing leaks and blockages in pipes, drains, toilets, and faucets
  • Maintaining hot water systems - Including boilers, water heaters, and unvented cylinders.
  • Installing and repairing water softeners and filtration systems

Heating Engineer:

Focus: Primarily deals with heating systems and boilers in homes.

  • Servicing and maintaining boilers and heating systems
  • Diagnosing and fixing heating system problems
  • Providing advice on energy efficiency and system upgrades

Overlapping Skills:

While their primary areas of expertise differ, domestic plumbers and heating engineers often possess overlapping skills and may be able to handle some tasks outside their core focus. For example, some plumbers are Gas Safe registered, allowing them to work on boilers and gas appliances. Similarly, some heating engineers may have experience with basic plumbing tasks like fixing leaky faucets.

When to Call a Plumber vs. Heating Engineer:

Call a plumber for:

  • Leaky pipes, faucets, or appliances

Call a heating engineer for:
