Good man. Keep an eye out on the channel - i’m going to stick up a video on ‘what to expect/what we need’ during a gas safety inspection… which other engineers are welcome to share. Basic stuff - like make sure you have gas and electric - call us if you need to cancel - and make appliances accessible (i.e. move your crap outta the way!)
