Course overview

Gas Engineers install and maintain gas appliances in a domestic or non-domestic setting.  Appliances can include but are not limited to, a range of work categories such as central heating boilers, unvented hot water storage, ducted air heaters, cookers, space heaters, meters, alternative fuel, boosters, testing, and purging for industrial pipework.

Roles in gas engineering are physical in nature and may involve lifting and moving equipment, working at heights, and working in confined spaces.

Customer service skills and being tidy and respectful are important qualities for a gas engineer as they can often find themselves working in customers’ homes. Responsibilities will include explaining how installations and appliances work, providing energy efficiency advice, and ensuring customer service excellence at all times.

By the end of the apprenticeship, gas engineers will be registered on the Gas Safe® Register as competent to undertake work on at least four appliances.

How much does it cost?


Course Length

Two to three years depending on the levels of experience the apprentice already has.

Entry Requirements

You will need to achieve Level 2 Functional Skills in English and maths, if you don’t already have these qualifications or equivalent GCSEs.

Equivalent GCSEs are grade C or higher or grade 4 or higher. If you are not quite at this level, you will have the opportunity to work towards these qualifications as part of your apprenticeship.

These qualifications need to be achieved before the End Point Assessment is taken.

In addition. you will need to be aged 16 and over for your employer to benefit from support funding.  If you’re older than 19, your employer may need to put some of their own money towards your studies.

You will need to have been a UK resident for the previous three years, or a national of any European Union (EU) country or European Economic Area (EEA) for the previous three years. This is unless you have an immigration status which exempts you from the three-year residency requirement. Contact JTL for more information about this.

You can apply for an apprenticeship while you’re still in education, but you need to have left before you can start with us. As a rule of thumb, you must have left compulsory education after the last Friday in June of the academic year in which you are applying.

You will need an employer before you can start an apprenticeship, although you can apply before you’ve arranged one.

How much does it cost?

The full training cost for a Gas Engineering Apprenticeship is £22,000, however as an apprentice you will not be required to pay anything towards your apprenticeship other than any travel costs you may incur getting to and from your employer’s workplace.

For employers there is no cost for hiring an apprentice aged 16 to 18 years.  If you recruit an apprentice aged 19 or over then the costs are 5 per cent of the full cost of the apprenticeship (e.g. £1,100 over 4 years).

For apprentice wages, JTL recommend that employers follow the JIB pay rates.

Please note: Apprentices who are aged between 16 and 24 years old, and who have been in local authority care are eligible to receive a bursary. This payment is paid directly to eligible apprentices via JTL. For apprentices who start their apprenticeships up to and including 31 July 2023, the bursary is a single payment of £1,000. It can only be received once by an individual care leaver. For apprentices starting their apprenticeship on or after 1 August 2023, the bursary will be £3,000. It is payable in instalments over the first year of the apprenticeship.

Delivery and Assessment

The course is usually delivered on a day-release basis, meaning you will go to college or a JTL training centre for one day a week and spend the rest of your time at work. Some of our centres offer a block release option.

The End Point Assessment (EPA) is expected to take place in the final 3 months of the apprenticeship. You must pass this to complete your apprenticeship and become a fully qualified engineer. The EPA consists of a multiple-choice knowledge assessment and a portfolio assessment which includes gas safe registration, a competency test, a work log review, and an interview.

Grades of Pass and Distinction are available.

“Personally, I think it’s the way forward. Some people go to universities when it just isn’t right for them, and actually an apprenticeship would be much better for them.”
