"Frazer offers an exceptional professional service that we've enjoyed for several years. He has a constantly calm, polite, honest and friendly can-do, positive attitude. Fundamentally, I've never known him to be wrong in his diagnoses including solving problems by phone: i.e., 'it may need about six restarts' - it did, precisely! And showing us the evidence that our 20 year old boiler is still working almost as efficiently as a new model. He works on time, very tidily and efficiently without rushing or spinning out a job. He quotes accurately and realistically and his invoices are itemised. He uses electronic communication in a low key but efficient way for helpful service reminders, on-the-job technical readings and invoices, and he's reachable by text and mobile. An absolutely top tradesman who we have already recommended to other happy oil-using neighbours."
