There is a skills shortage throughout the UK, and there has been for some time. Subsequently, a qualified gas engineer is in demand more than ever before. Existing engineers are overwhelmed with work and offered more than they can accept, meaning there is a waiting list of work to complete. As a result, there has never been a better time to learn a trade and become a gas engineer.

Whether you’re a beginner in the industry or currently working in a different trade, becoming a gas engineer is a significant step. Not only is being a gas engineer rewarding, but it’s also a profitable career.

Leaving your current role behind you and embarking on a new one can be daunting. However, it won’t be long before you can work as a qualified gas engineer.

What Are Your Options?

How long it takes to become a qualified gas engineer will depend on the route you take to get there. An apprenticeship is usually the first route people think about when learning a trade, and it is a route you can take to becoming a gas engineer – but there are others.

You’ll be in college and on-site as an apprentice, with a minimum of 20% of your working hours being hands-on. Typically, apprenticeships can take anywhere from one year to five years to complete and are generally aimed at those aged 16 and over. During your time as an apprentice, you will be able to earn as you train:

  • 16-18: £4.81 per hour 
  • 19+ (first year): £4.81 
  • 19+ (second year onwards: National minimum wage for your age

Apprenticeships are a popular choice for those without significant financial responsibilities, which is why they’re attractive to those just leaving education.

Training Courses

Training courses, however, can be completed in a shorter time, allowing students to earn a full wage sooner. With our training course, you’ll spend eight weeks in our centre learning essential skills and knowledge of the trade before going out on-site to build up a portfolio with your mentor. The time it takes to build your portfolio will depend on how often you can go out to work. The flexibility of the portfolio stage of training allows students to work around their existing commitments, such as other work and childcare.

We find that training courses are particularly popular with mature students looking for a career change. While they require an initial investment to cover the cost of training, you can become qualified and earn within a year.

New qualified engineers can expect to earn around £20,000, with the number rising to over £30,000 after a few years in the industry. (Source: CV-Library)

Gas Safe Register

To become a qualified legal gas engineer, you must join the Gas Safe Register.

Replacing CORGI in 2009, Gas Safe Register became the gas registration body. Gas Safe Register is the official list of businesses and engineers legally registered to work on gas appliances. It is a legal requirement that all gas engineers be on the register.

If you’re unsure what registering entails, look at our How to join the Gas Safe Register guide.
