How to Become a Gas Engineer UK

Logic4training’s Domestic Gas Heating Installer New Entrants Route is for candidates looking to become a Gas Safe Registered gas engineer but do not have the skills and knowledge to undertake the ACS gas assessments.

Start your career with us.

If you’re considering a career in the gas industry, becoming a gas engineer means completing recognised gas training and gaining the qualifications needed to work safely on gas appliances.

Our Domestic Gas Heating Installer New Entrants Route is a series of hands-on courses that equips you with all the practical skills and underpinning knowledge required to apply to the Gas Safe Register and work as a gas engineer in the UK. We’ve designed these New Entrants packages to provide a clear pathway into the industry, built around two core elements: the Domestic Gas Heating Installer Course and the Gas Managed Learning Programme (MLP) – specifically the DNGA3. Once qualified, you can upskill further to work on additional domestic appliances, commercial gas, LPG and heat pumps.

Already working in a related trade, such as plumbing or kitchen fitting? If you’re looking to complete your ACS and achieve your CCN1 and CENWAT, we also offer the Gas Managed Learning Programme in tailored, experienced-trades gas packages that recognise your existing experience.

Frequently asked questions

Need to speak to our team?

To become a fully qualified* registered gas engineer, you must:

Complete an on-site portfolio of gas work.
Undertake ACS training and assessment, which will result in a CCN1 qualification (core gas safety), plus the specific appliances you plan to work on – boilers, cookers and fires, for example.
Register with Gas Safe

Whether a new entrant or trades person with some relevant experience, our Domestic Gas Heating Installer (DGHI) programme, covers all of the above, plus other essential qualifications, such as WRAS water regulations and health & safety courses.

At the end of your DGHI programme you will complete ACS training and assessment; a pre-requisite of becoming Gas Safe Registered.

As part of the programme, trainees are required to build an on-site portfolio as well as five boiler installs, under the supervision of a Registered Gas Engineer – we can help with this aspect too.

On successful completion of the ACS assessment you will be ready to apply to join the Gas Safe Register.

To start on the first step to becoming a Gas Engineer, call our customer service team on 0208 845 7222 who will be able to advise and book you a slot on to the appropriate introductory session which are FREE of Charge.

*Core domestic gas safety qualifications with Boilers & Fires, additional appliances can be added later on. Commercial, Catering and LPG qualifications are also separate.

All our courses are full-time. Courses start at 8.30 am and usually finish at around 4.00 pm. You will be advised on your first day at the centre if there are any changes to these times. The centre is open from 8.00 am, and there is tea & coffee awaiting.

Gas engineers install, service, maintain and repair gas appliances in domestic and/or commercial properties.

As we move away from fossil fuels, gas engineers will continue to maintain exisiting boilers. In 2024, gas boiler fittings outnumbered heat pump installations by more that 15 to one. It is likely that these new boilers will last for around 20 years. Currently, there are around 23 million gas boilers in the UK.

Ultimately, gas is just the fuel; a gas installer should view themselves as a ‘heating engineer’. As a trained gas engineer, you will have the right qualifications and experience to upskill into increasingly popular renewable technologies, like heat pumps. These upskill courses take around five days, depending on experience.

A gas engineer who can also install heat pumps and other renewables, such as solar thermal, will be in demand now and in the future.

Typical duties may include:

Installing or repairing appliances to deliver gas
Repairing gas appliances and heating systems.
Maintaining or replacing faulty systems.
Cutting, bending & joining pipes and fittings.
Providing cost estimates to customers, and talking through additional cover, insurance options & energy saving options.
Carrying out estimates, checking for gas leaks & ensuring all repairs/installations are up to code.
Ensuring all safety requirements are met accordingly.

The Domestic Gas Heating Installer Course is only available at our Northolt Centre.

The Gas Managed Learning Programme is available at our Northolt, Luton, Basildon, or Sittingbourne Centres.

There are no entry requirements for this course, but we will assess candidates to check their suitability. A good understanding of maths and English is essential.
