Boiler started playing up a few weeks ago, it's about 8-10 years old.
Got a local heating engineer out (lots of good reviews, on the council's approved trader site etc) who fixed it - except a couple of days later it went wrong again. He came back, gave it a full service and said that the issue was with the gas valve. Everything else is working fine but that isn't - it's going in but nothing is coming out.
He said he can't replace it himself but advised me to contact the manufacturer.
Does this sound right? I've had this and previous boilers repaired a few times for minor issues but never been told to contact the manufacturer for a repair?
