Comustion chamber cover not boiler cover. An electrician doesn't need to go in there ( CCC) to change a timer.
Why anyone who isn't qualified in some way would go in there is,frankly,beyond me. There are some boilers ( Positive fanned)that could potentionally kill you if you open up the cumbustion cover and only someone familiar with these boilers should open them up.

That's what I thought but on the prog they clearly showed just the boiler cover being removed and they then said "that's illegal".... scaremongering then? or factually incorrect programme using incorrect advice from the "expert".
