ACS Gas & Renewables Training Course


Become a Gas Safe engineer through the Options Skills ACS Domestic Gas & Plumbing Maintenance Training Course.

With decades of industry experience, our team of tutors deliver the step-by-step training course at our centres in Birmingham, Manchester, Purley and Wembley.

After learning essential plumbing and gas skills in our centre, you’ll go out on-site with a qualified mentor to expand your knowledge and skills as you build your portfolio. In the final step of training, you’ll complete your ACS Initial Assessment, which then allows you to apply to join the Gas Safe Register.

Upon ACS Certification, you can upskill with our Renewables courses. Training in Low-Temperature System Design, Air and Ground Source Heat Pumps and Water Regulations will enable you to enter the renewables industry and future proof your career.

Through our combination of practical and theory learning, you’ll gain all the skills, knowledge and confidence you need to launch your career as a gas and heating engineer.

Footnote: Natural Gas will continue to play a vital role in heating our homes for a considerable time to come. Whilst there is talk of Hydrogen replacing Natural Gas, this policy is yet to be formalised, and specific training and qualification for Hydrogen does not yet exist. If and when the UK introduces it, it is likely to be in the form of a short conversion course for existing gas engineers. If the UK adopts Hydrogen as policy as part of the UK’s drive towards Net Zero, we will update our training provision at the earliest opportunity.


When you enrol on our ACS Domestic Gas & Plumbing Maintenance Training Course, you’ll be eligible to apply for twelve months of free Checkatrade membership.

Accreditation LCL Awards

Up to 31st December 2020 Regulated qualifications and UKAS Accredited certificates of competence issued in the UK were widely recognised by other EU member states. However since the UK’s withdrawal from the EU, individual member states that previously recognised a UK qualification may now no longer do so. Learners undertaking qualifications on the basis that it is recognised by an EU member state should in the first instance make enquiries with the relevant bodies in that Country to confirm its recognition status

Learning a trade such as gas and heating engineering opens up a world of opportunities. Not only will you learn a skill for life, but you create the opportunity to become your own boss. Being self-employed, you can set your working hours and pay rate and choose which jobs you undertake.

In the industry, you also get the benefit of variety. No working day will be the same; you’ll be working on different jobs, for different people and in various locations. However, as the industry evolves and we move towards a greener future, now is the time to train in gas and renewables; with a shortage of skilled workers across the board and an increasing housing market, tradespeople such as gas and heating engineers are in high demand. 

Tradespeople earn an average annual income of £32,500, but there is potential for an even higher amount.

Read Why Become A Gas Engineer and How Much Can I Earn As A Gas Engineer for more information.

Options Skills offer an excellent service, and we provide you with the best opportunity to begin your career as a gas and heating engineer. During your time here, tutors with years of industry experience will teach you the ins and outs of the industry.

You will also undertake on-site training, ensuring you’re fully introduced to the industry and have sufficient expertise before you begin working independently. Throughout training, you will benefit from a dedicated support team who will ensure training goes smoothly and who you can talk to if ever necessary.

And we continue to offer support even after you’ve completed your ACS Domestic Gas Training course.

No, this is a recognised gas qualification.

Completing the course will result in accreditation in Domestic Natural Gas and Unvented Hot Water Storage Systems (G3).

You will, however, gain essential plumbing maintenance skills that will assist in your role as a gas and heating engineer.

If you know an experienced gas engineer who is happy to supervise you, you can work with them to build your work portfolio. However, if you don’t, here at Options Skills, we guarantee to find you a qualified gas engineer to act as your mentor during step two of your ACS gas training course.

Due to years of experience in the industry, Options Skills have built up an impressive network of gas engineers, meaning we will be able to place you with someone local to allow you to complete your gas portfolio.

If you fail any of your exams, we offer students the opportunity to resit them.

In addition, Options Skills will provide students with extra training or support if necessary, free of charge to help prepare you for your re-examination.

If you have previous experience and have obtained your ACS qualifications, you can undertake our add-on courses in renewables. If you have not completed an MLP, you will be required to complete the ACS Domestic Gas Training Course. The best course of action, if you have experience in the industry, is to call our advisors to discuss your situation.

Options Skills are in no way able to guarantee any student will pass the exam.

However, we provide our students with expert training, which, combined with hard work and dedication, will give you the best opportunity to pass the exam.

While we will provide students with excellent practical and theoretical training, we will not teach them how to pass the exam. Therefore, passing any exams or assignments is dependent on your level of knowledge, dedication and hard work.

Option Skills - BirminghamI’m not usually a person who will write feedback on Google, but I am someone who will give credit where credit is due.I found myself in a position where I had been made redundant, and id had a conversation with someone who’d decided to go on a gas course and do this through Option Skills. After speaking with the individual, I decided that id give this a go myself to give myself a trade.I can honestly say that it is better than anything that id ever expected. Iv always been someone who had worked in finance, so doing this was new to me and I was a bit apprehensive with how it would go.I have nothing but praise to the employees at Option Skills, and I feel that they are a credit to the company.Andrew, Leanne and Shaun have been the people taking the training sessions, and what incredible people they are.They are extremely knowledgeable and helpful in every way possible with an extra desire to wanting to see you achieve.I have done the course for 8 weeks, and the knowledge I have picked up already is immense.If you are someone looking to get into the gas trade, I would highly recommend Option Skills as you will not be disappointed.Carl Evans

Although this course is intense and you will find yourself picking up a lot of information in a short space of time, Options Skills are the best way to get into the trades if you are a fast learner and are willing to work hard. The trainers are excellent (John, Steve, Thomas) and they will help you wherever they can, however be prepared to put in the work yourself in the evenings and weekends to revise and pass exams. Josh and James from the recruitment team were a joy to work with, they work tirelessly to find us all placements to start working in the industry while you complete the portfolio part of the course. I just finished the Electrical 6 week course and the lads found me a job in Birmingham city centre. With a number of exams left to do and portfolio to complete after you finish the 6 weeks in-centre, you can expect the total time to reach being qualified to be around 1-2 years.

Really recommend this training centre. Just finished a 6 week electrical installation course. Tutors Colin and John were great, they were knowledgeable professional and very supportive throughout. Josh and his recruitment team managed to find me a job in the industry starting the Monday after I finished the training. 5 stars all round from me. Thank you to everybody at option skills and keep up the good work!!!
