The qualification scheme for gas work in the UK is called ACS (Accredited Certification Scheme). ACS includes qualifications in several different core areas including domestic, commercial industrial, commercial catering, LPG, and meter installation.
Before taking ACS assessments, if you do not already have a recognised gas qualification, you must first complete a managed learning programme such as the Guild of Gas Fitting Operatives (GGFO).
The GGFO consists of off-job training, on-job training, written exams and practical assessments.
This consists of a total of 25 days at our training centre in 2-week, 1-week and 1-day blocks spread over a number of months. Classroom and workshop lessons cover all the required knowledge and practical skills needed for ACS including:
Safe isolation of electrical supply
Pipework design and installation
Flues and chimneys
Complete and incomplete combustion
Using a combustion analyser
Gas pressures and flow rates
Appliance install, commissioning, inspection and servicing
As evidence of on-job training you must complete a portfolio of gas work under the direct supervision of one or more Gas Safe registered engineers. We supply you with a blank portfolio workbook of 80 Gas Work Records to complete.
The first 15 Gas Work Records can be completed by simply observing your supervisor doing gas work. Then, as you learn the job, you should do more of the work yourself. At the end of the portfolio you should be able to do all aspects of the work. Please note that your supervisor must be present at all times while you are doing gas work.
The GGFO assessment
When your portfolio is complete you return to the training centre for practical and written exams. This takes 3 to 4 days. If successful, you will receive a certificate that allows you to take ACS assessments. If you are unsuccessful at the first attempt of any assessment you can retake all or part of it free of charge.
