Quick guide summary

When should I call a plumber and when should I call a heating engineer to attend?

We often say “I need a plumber” when we need someone to work on our boiler or heating system. A plumber can work on your heating system (radiators, pipework etc), but cannot work on the boiler or the gas pipe. The main difference between a plumber and a heating engineer is that a plumber does not carry any gas safe qualifications. On the flip side, a heating engineer that mainly does boiler repairs is unlikely to work on any other aspects of your heating system. Use our handy table to find the right trades-person for your job. How else can we help? We provide guidance on using an 'Approved Installer', finding your Best Boiler and many other topics in our Information Hub.

Who should I use for my heating or plumbing job?

Heating and plumbing jobs are incredibly varied and require different skill sets. An experienced boiler breakdown engineer that is very skilled in repairing boilers may not get involved at all in heating system work, such as changing a radiator or fitting a new thermostatic radiator valve. A plumber that specialises in bathrooms may carry out radiator swaps and powerflushing but does not get involved in repairing a boiler. Of course some trades people are multi-talented and will do everything! Most tend to specialise.

So who should you call when you have a plumbing or heating based job? We have put together a handy table to help you identify the skill set you need for your works.

Where can I find the right tradesperson?

Who you need will determine where you look. That said, many trades persons sites list all trades so you are best to also look at the website and profile of a local person and work out their skill set.

Find a Plumber

google business listings are a great way to find a local plumber. Google ‘Plumber Near Me’. They will definitely be geographically close and will hopefully have some google reviews. Alternatively look at Check a trade or My builder websites.
