Boiler was serviced this morning by Andy. For the first time I have witnessed what a proper boiler service should be. He pointed out that the boiler has never been properly serviced and was full of dust and debris. The fixing bolts had never been undone. The igniters were corroded and not properly set one them being broken. (He ordered a new one straight away). Previous claim was that a new gas valve was fitted in 2017. Andy says the valve has never been renewed. The heat exchanger is in poor condition and should be replaced. The boiler was running gas rich. Andy adjusted settings. Seems the previous engineer (Phil) was not attending amazing just a few tests with meters and claiming a full service. Andy has restored my confidence in Alpha and obviously knows his duties well. Friendly and customer concerned
