Why train as a gas engineer?
Training or retraining to be a gas engineer could be a great option for you.
You may be:
- In a job you don’t like and keen for a new challenge.
- Leaving or graduated school and now considering career options.
- Already working as a tradesperson but want to gain new skills and qualifications.
If you fall into any of these areas, then training to be a gas engineer is an excellent career choice.
Working as a gas engineer requires a wide range of technical knowledge. It can be challenging but it is also highly rewarding. Rates of pay are generally excellent, and you can expect good levels of independence and flexibility in your working life.

What does a gas engineer do?
Gas engineers install, service and maintain all types of gas appliances. Gas engineers work in both the residential and commercial sectors, often alongside other trade professionals on construction sites and in people’s homes for renovation projects.
Gas engineers also work with gas pipe systems; cutting, bending, and fitting pipes to connect appliances to the mains gas source. Gas engineers will also be required to attend to suspected gas leaks and ensure the suspected leak is made safe.
All gas engineers must be certified as Gas Safe to work on gas appliances and supply systems.
How to choose the right gas training provider
Once you’ve decided to become a Gas Safe engineer, you’ll want to know your first steps to make it happen. You’ll first need to find a quality training provider.
There are numerous companies offering Gas Safe courses across the UK. Options Skills are a provider we work with.
Who are Options Skills?
Options Skills are a nationwide training provider who formed in 2013. They are Trading Standards Approved, have four training centres across the UK, and have many positive customer reviews (over 1000 on Google).
Options Skills offer a wide variety of gas engineering courses. Courses are initially based in one of their professional training centres. Here you’ll learn the theoretical side and the essential practical skills of becoming a Gas Safe engineer.
Following your time in the training centre, you’ll then be placed with an experienced and fully qualified mentor. You’ll go on-site and learn hands-on, expanding your knowledge in a real-life working environment.
Finally, you’ll complete an ACS Initial Assessment. Once this is successfully completed you can apply to join the Gas Safe Register.

Concerns about gas vs renewable energy changes
There is currently a drive to reduce carbon emissions worldwide. In the UK alone, natural gas is set to be phased out and replaced with renewable energy sources with no new gas boiler installations after 2025.
So, is it worth retraining as a gas engineer?
The answer is most definitely yes.
Almost 86% of UK homes use natural gas to heat their homes. There are an estimated 22 million gas boilers in homes across the UK. Once the new gas boiler installation date has passed, all these boilers will still require regular servicing and maintenance.
The long-term plan for UK energy will likely use a combination of natural gas and hydrogen. The infrastructure for hydrogen power in the UK is still being developed.
Gas training centres, however, are already planning to offer updated training provisions to existing Gas Safe engineers to ensure they are fully compliant with new hydrogen system installations.
How to get experience once trained as a gas engineer
Once you’ve completed a gas training course and you’re Gas Safe registered, you’ll want to find work. There are several ways to do this.
If you already work as a tradesperson, you can offer your new skills to your existing contacts.
You can apply for gas engineer jobs, using sites like LinkedIn, Indeed and Total Jobs.
You could talk to your training provider who’ll likely have industry contacts.
You could go it alone and start a new business. One of the best ways for a newly qualified gas engineer to find work is to create an online profile and start building your reputation.
A great place to start building your business and getting your name out there would be through Checkatrade. In fact, everyone who graduate with Options Skills from the ACS Domestic Gas & Plumbing Course bag themselves a free Checkatrade membership!
After passing your gas course, you will:
- Be a recommended tradesperson on the UK’s most trusted directory.

As you can see, training or retraining as a Gas Safe engineer is an excellent career choice.
