So, the guy comes back...

...to check out the boiler, this time, I decide to sit and watch him work...no joke, he tries for almost an hour to get any smoke at all (btw - he is making the smoke by lighting pieces of kitchen paper with a cigarette lighter, which struck me as rather dangerous) to do *anything* other that get sucked straight up the chimney vent. I kept on saying "Oh that's great, so it's all fine after all then?", and he is like "Nah, just need to do some more checks"...so, getting rather bored of his performance I decide to enquire as to exactly why he is using kitchen paper, and not a smoke bomb like the guy that did the test for us last year...he pauses for a minute and then says "Oh, well, yes, I could do, yeah"...after watching all the smoke zoom straight up out of the roof, he *still* won't concede that all is well..."It's borderline" apparently....so he carries on with the kitchen roll trick...Flyingpops then arrives back home, I come downstairs to tell her the good news, and suddenly and mysteriously it's (in the last 3 minutes) stopped working! Anyway, so I have to nip out to the shop quickly and by the time I have got back he has left, saying it's okay after all, charged us £40 and not issued a safety certificate...cowboy...!
