Dean comes with my highest recommendation ... and I'm someone who very rarely writes recommendations.
Over my 30 odd years of home ownership I've had occasion to engage numerous builders and trademen with, at best, patchy results. Dean has been a refreshing change from the norm. He is very reasonable with his charges, but also punctual, tidy, honest and reliable.
In the case of our ancient boiler he needed to make several trips back to sort out various related problems that developed - problems that were not really his fault - but he made no additional charge and resolved them all with a smile.
It needs to be said that a heating engineer prior to Dean condemned this boiler and advised that it couldn't be repaired; that we needed a new unit. Suffice to say we've saved several thousand pounds from not following that advice and from using Dean instead.
Dean's number has gone into our phone book now and he'll be the only heating engineer we call should we run into trouble. We've recommended him since to friends and family and I unreservedly recommend him to you, too.
