Boiler failure at 07:30; tradesman request at 07:45; Aldo (A3 gas) rang at 08:15.
Agreed time to call - arrived 5 minutes early after confirming he was on his way.
Identified problem straight away and quoted repair price. Unfortunately repair was not as straightforward as originally thought (although the diagnosis was correct). After heroic effort (including coming back the following day (at time promised)) boiler fixed, serviced and refurbished. Only additional costs above quote were for parts.
Clean, tidy, personable and skilled. I would wholeheartedly recommend Aldo to anyone.
