Stephen arrived right on time and was polite very knowledgeable and explained what he would be doing to service my Baxi boiler. He carried out the service and also explained to me the setting of my boiler to save money on my heating I had been reading about on the Web and in newspapers. He also advised me on turning off radiators in rooms I don't use. I am very happy with everything he did and would recommend you give him a call for your job. I am passing his number to my friend. Thank you Stephen
