What is a Gas Engineer?
Before we delve into how you become a gas engineer, what’s involved in the job? Gas engineers are responsible for the installation and maintenance of systems and appliances that operate using natural gas, such as boilers.
Because of the potentially hazardous nature of this flammable fuel, gas engineers are a highly specialised, well-respected profession. They need a lot of training and even once qualified, they must stay up to date with the latest regulations and techniques to make sure they’re safe and operating within the law. They also conduct routine diagnostics, repairs and emergency services for cookers, water heaters and other gas appliances.
Steps to Become a Gas Engineer
People become gas engineers by following a number of steps, including completing an apprenticeship or training course, building a portfolio, undertaking accredited certification scheme (ACS) training, submitting to the Gas Safe Register and finally, finding work either as a sole trader or with an employer.
We’ll go into more detail about each step below, so stick with us as we take you through the path to becoming a gas engineer.
01 – Find and Complete a Training Course
The first step on the road to your new career as a gas engineer is to complete a training course. This will equip you with most of the theoretical knowledge and practical skills you need. An alternative route is to complete an apprenticeship.
At Midlands Gas and Electrical Training Centre, we provide comprehensive gas engineer training that blends practice with real-world, on-the-job experience in the company of an experienced engineer. Over 24 weeks, you’ll complete six weeks of training at our centre, before heading out with one of our qualified trainers to perform a minimum of four boiler installations and four boiler services over the remaining 18 weeks. Once your training is completed, you’ll be issued with a Gas Safe qualification and able to register for your initial ACS Assessment.
02 – Build Your Portfolio
Our next stage in how to be a gas engineer is to build a portfolio of work. This will showcase your workmanship to potential employers and can help you when it comes to the next step which is registering for ACS training.
In the process of completing gas engineer training with Midlands Gas and Electrical Training Centre, we’ll help you build a portfolio of work through practical, real-world installation and maintenance projects.
03 – Finish ACS Training
Once you’ve completed your apprenticeship or training and built a portfolio of work, you can register for an ACS training course. There are six different ACS course types to choose from including domestic natural gas, commercial heating, commercial catering, commercial laundry, emergency service provider and metering and liquid petroleum gas.
Each course will lead to a different career path, and all are overseen by the United Kingdom Accreditation Service (UKAS). All courses will involve multiple-choice theory, written theory and practical assessments, and will need renewing once every five years.
04 – Sign Up to the Gas Safe Register
Your penultimate hurdle in how to become a gas engineer is to sign up to the Gas Safe Register, which you can do within two weeks of completing your ACS training. You need to be Gas Safe registered to legally work on gas appliances and systems in the UK, Isle of Man, Guernsey and Jersey.
The scheme is operated by the Health and Safety Executive (HSE) to protect the general public from unscrupulous engineers. Registration costs £480 plus VAT, and once registered, you’ll be free to find your first job as a gas engineer!
05 – Find Your First Job!
Well done! You’ve made it through all your training and signed up to the Gas Safe register, you’re now fully qualified and legally allowed to practise as a gas engineer in the UK.
The final step is to find work. You can decide to go it alone as a sole trader and buy your own tools and van to work for yourself or apply for a job with a business which employs gas engineers such as an energy company.
06 – Upskill With Industry Qualifications
Expand your skill set, knowledge and accreditations with any of our gas and electrical training courses. This includes Boiler Fault-Finding Course, Unvented Hot Water Course, Water Regulation Certification or LPG Course.
Skills Needed to Become a Gas Engineer
When you train to be a gas engineer, there’s a multitude of skills that’ll likely be incredibly helpful to possess or hone, including customer service, time management, maths, technical skills and problem-solving.
Let’s run through these skills and why they might be handy:
Customer Service
You might not have considered this one, but customer service is one of the most important skills you can possess. When you go out to conduct repairs, you’ll be working in peoples’ homes and handling situations where people are potentially frustrated and stressed.
You’ll need to be able to calmly put peoples’ minds at ease, be respectful of their homes and explain the work you’re doing and offer any advice to help prevent issues from recurring. These positive interactions can lead to word-of-mouth recommendations, which is one of the best ways to grow your customer base.
Time Management
Whether you work for yourself or a company, you’ll have a schedule of appointments to keep. One of the key skills needed to become a gas engineer is to be able to properly manage your time.
Running behind for booked appointments can leave customers frustrated and damage your reputation as well as that of your employer.
Maths
When you become a gas engineer, you’ll need to have a basic understanding of key principles of maths, as you’ll have to take measurements, identify patterns and spot issues using mathematical deductions.
While your training or apprenticeship will equip you with many of the skills you need, it’s helpful to have some sort of grounding in maths before you start, as it’ll make your training and your work much easier.
Technical Skills
It’s hugely helpful to have some form of basic technical skills and experience using tools or working with your hands when training to be a gas engineer; even the most basic experience will give you a leg up.
As you go through your training, you’ll develop more complex skills and a portfolio of work that showcases your technical competencies.
Problem-Solving
In your day-to-day work as a gas engineer, you’ll be constantly required to identify and solve problems. Your ability to think creatively and adapt to new and changing situations will be tested every day.
Problem solving skills will be vital, and if you can demonstrate these before you even begin training, you’ll be in good stead for the rest of your career.
Initiative and Leadership
Demonstrating leadership traits and initiative is highly valuable for those who want to learn how to become a gas engineer. This can entail everything from regular hands-on practice to participating in active demonstrations for others to learn. Small, consistent habits such as assisting colleagues are one way to take initiative and lead by example.
