About the ACS Domestic Gas Safety and Appliances – Refresher Course
This reassessment programme is suitable for qualified gas engineers looking to renew their Accredited Certification Scheme (ACS) competencies and relevant appliance scope extensions. It forms part of our wider gas training courses for existing engineers maintaining and developing their professional competencies.
The reassessment program consists primarily of self-study, with learners having access to the latest manuals to confirm and refresh their knowledge. Assessment takes place over 2 or 3 days and involves practical demonstration and completing question papers.
Add Appliance scope extensions to your competency
Why not include some new Appliance “bolt-ons” to your reassessment? Include just one additional Appliance or complete reassessment for CENWAT, CKR1, and HTR1
Did you know you’re able to renew your ACS qualification 6 months prior to its expiry and still retain the original expiration date? Complete reassessment before your competency expires to add scope extensions to your ACS qualification even sooner.
How is the ACS Domestic Gas Safety and Appliances Reassessment program delivered?
The assessment takes place over a number of days (between 2 and 3), at our Stafford training centre. You’ll participate in a blend of observed practical assessment and paper tests.
The majority of learning is delivered via self-study; however, our qualified gas engineers are on hand to support or advice on appliance scope extensions.
Here are some of the scope extensions we can assess:
