I called at 14:00 for a heating engineer to come and sort out my heating that was not working. The web site says that someone will be with you between 1-3 hours, the engineer eventually arrived at 18:45hrs who had travelled from his last job which was Twickenham, I was in Milton Keynes. Give the engineer his due, he found the problem fairly quickly but did not have the part on his van. Due to the weekend upon us the engineer kept to his word and came first thing on Monday. His working ethic was great and his work was clean and tidy. He didn't try and spend more than necessary doing the job, mind you he did have to travel to Slough for his next job.
