  • Entry Requirements

    The Commercial ACS Gas extension to Range & Scope course is for Gas Safe Registered operatives who need to renew their commercial ACS qualifications.

    These changes reflect the NEW Pre-requisite Training for experienced operatives as Published in GN8

    In a nutshell If you have been Gas Safe Registered for over 6 months and have  the domestic or Commercial core on your certificate then you are suitable for this course. If you have no previous on-site experience, we will carry out RWE (Real Work Environment training & experience in accordance with GN8 prior to assessing you). If you wish to add a further scope (e.g Commercial Gas) we will require you to book onto our Commercial ACS Gas Extension of Scope course where, if you have no previous on-site experience, we will carry out RWE (Real Work Environment training & experience in accordance with GN8 prior to assessing you).The scheme expects engineers to gain some experience in what they’ve been trained initially before extending the scope of their work.

    Please note: These changes are nationwide and are not coming from CCTS. All training centres in Britain & Northern Ireland will have to adhere to the new requirements. 

    In order to undertake re-assessment, operatives must complete the course no more than 12 months after the expiry date of their existing qualifications.

    The core re-assessment can be completed up to six months before this expiry date.

    Gas installers who have held the qualifications previously but have let them lapse by more than 12 month, must undertake a Managed learning Programme (MLP)

    Candidates who have never held a core but have transferable skills and experience may be eligible for the Logic MLP (Managed Learning Programme)

    Gas Safe Registered Operatives may only undertake gas appliance re-assessment in modules which they have previously been certificated under the ACS scheme
