When something goes wrong with your central heating, boiler, or gas-related appliances, it can be very frustrating. The fact of the matter is, you will likely need a qualified and certified gas engineer to fix the problem for you.

What do Gas engineers do?

A gas engineer is someone that is responsible for installing, extending, and repairing gas related appliances.

The reason you will need to hire a certified engineer to solve gas related problems is because they are particularly qualified and trained to run gas lines necessary for boilers, gas cookers, and whatever gas-using appliances you might have.

Due to the nature of gas plumbing itself, it can be quite a tricky and dangerous area. You will need someone who knows what they are doing in order to ensure they get the job done safely and efficiently.

What is the difference between Gas Engineers and Plumbers?

A plumber is someone that carries out installations, maintenance work, and repairs of items related to taps, sinks and toilets. They are also likely to know a lot about dishwashers, washing machines, and other household appliances.

Plumbers can also be Gas Safe certified, depending on whether they have the specific qualifications or not. They do not always come together, however.

When contacting a plumber to carry out work on appliances such as boilers, gas cookers, and heating systems, you need to ensure that they are Gas Safe certified.

They should be able to provide you with a Gas Safe registration number to prove this. There are yearly tests with thoroughly assesses their ability to work with gas, meaning you will be in safe hands.
