Neil came to my rescue after being let down by the company who serviced our boiler. Phoned Neil Friday evening explained our problem, he came over on time given on Saturday morning diagnosed problem and let us source the part.
Within 3 hours of diagnosis, problem was solved and we have heating again.
I was also pleasantly surprised at the cost of his services, so much so we are booking Neil to replace our boiler in May.
Cant recommended this guy enough.
