The Nationally Accredited Certification Scheme (ACS) is the industry recognised and accepted route for operatives to gain a certificate of competence, needed to become a member of the Gas Safe Register. ACS covers all areas of gas work including domestic NG, LPG, commercial heating, commercial catering, commercial laundry, meter installation and emergency service provision. The scheme is overseen by the United Kingdom Accreditation Service (UKAS).
Joining the Gas Safe Register
You need to achieve your ACS qualification (or S/NVQ equivalent) in the areas of work in which you want to be registered. On receipt of your certificate of competence, you will then be ready to apply to Gas Safe Register. The Awarding Body Certification will have downloaded your details to Gas Safe Register at the same time as issuing your ACS certificate of competence. A probationary period is required by Gas Safe Register for newly qualified operatives or lapsed registration. During the probationary period you must keep a record of all gas work carried out for Gas Safe Register to inspect. Certain tasks, like the installation of an appliance, must be notified to Gas Safe Register as detailed in the rules of registration. Registration with the Gas Safe Register is a legal requirement for anyone carrying out gas work in the United Kingdom, Isle of Man and Guernsey. ACS Elements Required
In all areas of gas work there is a core gas safety element which must be achieved before an individual appliance assessment can be undertaken. There are core gas safety elements for domestic NG, LPG, commercial heating, commercial catering, commercial laundry, emergency service provider and metering.
Domestic Natural Gas:
Core Domestic Gas Safety – CCN1 (compulsory), now includes combustion performance analysis Once this has been completed, the appliance assessment relevant to your work can be completed:
Central Heating Boilers & Water Heaters – CENWAT Cookers – CKR1 Gas Fires – HTR1 Meters – MET1 Warm Air Heaters – DAH1 For those moving from one ACS core to another there are changeover assessments that will assess the candidate in the areas that are not common to the original core. The candidate would then take the relevant appliance elements in relation to their specific job. Candidates should speak to their local approved ACS centre before undertaking the changeover assessment as additional training or experience may be necessary.
