Do I need to undertake this specific course to become a member of the Safe Gas Register?2023-10-31T12:08:02+00:00

Not necessarily. This course (MCA3) is regarded as an equivalent to a Level 3 Qualifications and Credit Framework (QCF) or Regulated Qualifications Framework (RQF) qualification in the gas utilisation sector. Because these qualifications are also aligned to ACS, they satisfy the same gas safety criteria leading to a certificate of competence recognised by the Gas Safe Register.

I’ve held this ACS certificate before – can I enrol in the Refresher version of the course?2023-10-31T12:07:14+00:00

Yes, if you currently hold the ACS Core Domestic Gas Metering (CMA3) certificate and it hasn’t yet expired for 12+ months, you can enrol in the Refresher version of this course.

If you hold an ACS Core Domestic Gas Metering (CMA3) certificate that has expired for over 12 months, you will need to enrol in the Foundation version of the course to renew your certificate, regardless of your professional experience.

What happens if I fail the exam?2024-02-07T14:13:54+00:00

If you were unable to successfully pass the assessment phase of the course, you would be referred and together, we’d work out what approach is best for you.

If a candidate wants to retake their exams, we provide you with the opportunity to re-sit any module exam for free. We’d also work with them to ensure they can further develop their skills and practical experience, giving them the confidence and knowledge to hopefully pass their exams this time round.

If we or the candidate feels they need more significant support or that the course isn’t suitable for them, we would work with the candidate to work out the best outcome for all.

Recently completed the Low-Temperature Heating & Hot Water, Water Regulations, and Heat Pump courses at this centre. Kay’s quick replies to my emails made the whole process smooth, and the flexible date options were a real bonus. On the course itself, Matt was an excellent tutor—clear, practical, and bringing years of real industry knowledge to the table. I’d definitely recommend this centre/courses and I’m already looking forward to coming back for the Solar PV & Battery Storage course.

Recently used this company for an air source heat pump course. Very informative and always willing to go that extra mile that allowed me to pass the course first time having no knowledge and never touching air pumps before.
