How to access ACS training for the first time?

There are no short cuts to becoming a registered gas engineer.  Gas Safe enforces a rigorous system for checking the suitability of gas operatives, before permitting them to join the register in order to carry out unsupervised gas work.

Before a gas operative can begin their ACS training, they must be able to demonstrate a minimum of 12 months on-the-job experience working under the supervision of a Gas Safe registered engineer.  In addition, they must hold a valid pre-learning gas qualification.

Whether you already have a Gas Safe registered engineer working with you will significantly affect the cost and duration of the training.

I have a Gas Safe registered engineer working with me

The good news is that if your business already has a Gas Safe registered engineer who can supervise the learner, or a friendly contractor who is prepared to help, the route to ACS is substantially easier and less expensive than the candidate attending a full managed training course.

The candidate must be able to demonstrate 12 months of experience working under supervision on-the-job gas work (i.e. work that is practical to LPG gas on caravan parks). This must be confirmed by the appropriate registered gas engineer.  Once the candidate has gained some experience, they will be ready to take a pre-learning qualification (PLQ).  We do not have a park specific PLQ, however, our standard five-day STGW gas course for caravan service technicians can be used.  Having at least six months experience working on a park, will be important to the learner as the STGW course focuses on touring caravans and motorhome gas systems, which the learner is unlikely to be familiar with.  Once they have completed their STGW they will need a further six months experience on-the-job before they can attend an ACS course.

The advantage of working with a registered engineer is that the learner can acquire their experience in-house, which significantly reduces the cost of their training to your business both in terms of direct cost and time out of the business attending courses.

I do not have a Gas Safe registered engineer to work with

If your business does not already have a Gas Safe registered engineer that the candidate can shadow, they will need to undertake a managed learning course, that will take them through initial gas awareness training, a pre-learning qualification, provisional or practical experience and finally their ACS training and assessment.  This course takes place in Flintshire and typically lasts between 30-40 days over a 12 month period.

ACS qualification units

An ACS gas qualification is made up of a number of mandatory core and optional appliance units.  The minimum number an operative can take is; one core unit and four appliances.

The specific units the candidate will require will depend upon the scope of work they intend to carry out and on what appliances.  We will discuss this work with you, so that we can advise you on the appropriate units your operative will need.

Cost and duration

The ACS course is tailored to each candidate; therefore, the duration and cost is reflective of their individual requirements and their chosen centre.  The standard package of training and assessment in mandatory and optional units takes approximately 5-8 days (not including weekends) and a typical charge is between £1200 - £1800 + VAT.  We will advise you upon the units you require for the scope of gas work you intend to do and your final quote will be specific to the package designed for you.

Please note the above charge includes the candidate’s training, assessment, handbooks and certificate; however, it does not include Gas Safe registration, which you must apply for individually.  We will give you a specific quote based upon your requirements for your ACS but we strongly advise getting a quote from Gas Safe for registration before undertaking this course.

Upon successfully completing the course you will be issued with an ACS certificate and ID card with which you can apply to Gas Safe to become a registered gas operative.  Your ACS certificate will be valid for five years, after which time, you will need to be re-assessed.

ACS gas re-assessment

The ACS qualification is valid for five years, after which time, gas operatives will need to attend a re-assessment course.

Like the initial ACS gas training, the re-assessment is tailored to the individual operative’s requirements.  An operative can choose to re-assess on their existing units with or without training (depending upon how confident they feel in the re-assessment), add additional units if their scope of work has increased (training is mandatory on additional/new units) or reduce the number of units if the scope of their work has decreased (a minimum number of core and appliance units is still required).

Cost and duration

The cost and duration of re-assessment will depend upon the units the technician requires assessment on and whether they require training.  Re-assessment only typically takes between 3-5 days with prices starting at £900 + VAT.

Gas operatives can begin their re-assessment up to six months prior to their existing certificate’s expiry date.  The new expiry date is calculated from the original certificate’s expiry.  This therefore allows the engineer to be re-assessed in plenty of time without losing any of their certificate's validity.


Requesting a quote and availability

As a gas operative's package is tailored specifically for their requirements, we are not able to list specific training dates.  In the first instance, we will discuss your requirements with you, when you want/need to do the training/assessment and which of our gas centres you would like to attend.

Initial ACS training and new gas operatives

Please contact us so that we can discuss your requirements and advise you on the most suitable route to ACS for you and your business.

This allows us to advise you based upon your individual circumstances.
