Had the boiler less than a year, I've had to have them back out twice for different reasons. The engineer who came this time tried to pull the door off the wall to get to it rather than unsrew the screws. He was rather rude when i explained what the problem was, he wasn't listening and had to tell him 3 times. Then when asked if he had put the door back on he said no and refused to put it back on. After asking him a few times he did but his body language and the way he was speaking wasnt very nice at all. I've only put 1 star as it doesn't give you an option of zero
