Background : moved into new house Dec 2015. Lovely area but v v cold & windy. Decided to upgrade boiler, eventual cost £2250. Kitchen was left as show by fitters of the boiler yesterday. Plastic ducting to left leads to large bodged hole right through front of house which they made in the name of extractor from hob needing to vent away from boiler. Now have perfect storm of two parallel holes in kitchen, high wind, dust & plaster lying around & broken tiles. AIBU to be pissed @ DH who was here 'supervising' and 'didn't notice' the bodgery as he was too busy making them cups of tea ?
