New Entrants into the Gas Industry (Category 2/3)

Preferably, but not essential, prior to commencing training, you are working under the supervision of a GAS SAFE registered installer.  Alternatively, following the Gas Technology training, you will need a work placement with a GAS SAFE registered installer.

Due to the rigors of the assessment process, candidates will need to consider their position carefully as to the depth of their pure gas working experience covering core gas safety, installation and maintenance of appliances in order to obtain written evidence from the GAS SAFE registered business.  The written evidence will confirm you have undertaken ‘on the job’ gas installation or maintenance training and have experience of carrying out gas work.
