4 years ago my boiler died so I started looking for a tradesman to put a new one in. Nobody except Polar Heating wanted to fit anything that wasn't Worcester/Bosch. My old boiler wasn't Worcester/Bosch, had done sterling service for 14 years (without a service, ever! Bad me!) so I didn't want to spend mad money on W/B. Despite my somewhat aggresive "before we waste each others time, do you fit ANYTHING that isn't bloody Worcester/Bosch????" Dave was very polite and professional in his reply, which was basically "you can have whatever you like!". These two really are the nicest of folk you could hope to meet and are grafters, hard workers who left my kitchen cleaner than it started, managed to work around the house being FULL of wholesale stock ready for dispatch and a nutty Rottweiler attempting to assist them by running off with gaskets and generally getting in the way constantly. The boiler is great, still working at A1 performance and Zol pitched up this morning, bang on time as ever, to sort out my bathroom taps and mixer tap in the kitchen both of which were driving me utterly nutso. Job done in no time flat, and as usual a cheery smile, a great price and again leaving the place in better order than it started! Can't fault Dave and Zol, who have now done other work for me, my mum and countless friends.
