I'll point you in the right direction. Don't waste any more time and money, if you've any other skills find another trade. Gas is sh*t.

Tibbot is not necessarily wrong.

But, As to how format a presentation on the subject? Give your classmates a one word answer. RTFM.

its all in the books you are given/have paid for as part of the course fees.

Get them to read it for themselves.

If you ever have a Gas Safe Inspector call to look at your work, he will not expect you to be able to answer every technical question, but he will expect you to know where to find the answers. in this case though, Keywords might be adventitious, or first seven kilowatts etc

Thats it for free gas advice, join the CC when you get your own GSR number.

Seriously OP. You are what may seem like light years away from being a time served gas engineer, which still offers little reward. It would take less time to do the knowledge, your HGV, Trainee train driver etc.. All of which offer better earnings, more continuous work and infinitely less grief.

There's far too many guys doing gas work & the rewards are limited. 20 years ago it was the thing to get into, but there's too many course Cowboys & career change chancers about to make any money at it. With the huge on-costs of training, registration & equipment, you make no more money than a washer changer Plumber or Handyman.

It's a laugh driving around Edinburgh, all the Landscape Gardeners bomb around in top of the range pick-ups & then there's the Gas engineer in his 01 plate sh.gged out Connect........
