Having previously had the same heating engineer for over 30years, had since been hard to find another, which resulted in some poor service. My son looked up traders in Which and I am happy to say that Barnaby of Westflow Ltd has come up to the mark. He and his colleague were friendly, capable, clean workers and arrived early, and left late and system, which is elderly like me, is now working better than ever, unlike me. Thanks to Barnaby and Joe.

Westflow recently replaced our old boiler with a Worcester 8000 combi. They also fitted an additional radiator – an awkward place to fit it in! We found their quote very competitive and informative. Barnaby and Jow were punctual, professional and extremely courteous. They laid sheet covers wherever they worked and once they had finished, they swept and hovered the area. The old boiler and the rubbish was taken away by them. We have asked them to carry out future annual services. There was a very small issue with the new radiator, which, they sorted out within couple of hours after making them aware of it. We will very highly recommend Westflow to our friends and family. It was very refreshing to get this kind of excellent service these days!

Barney installed a new boiler and has maintained our heating system for several years, as well as dealing with other plumbing issues, such as tap and radiator valve replacements. He has always been extremely helpful and reliable.

We have been regular customers of Westflow as they installed our boiler. Other tradesmen have been most complementary about the excellent pipe work! But more importantly, Westflow have shown themselves to be competent, reliable and trustworthy with regular servicing and the odd emergency heating need. Highly recommended.

Replacement boiler fitted in airing cupboard. Excellent service, reliable and tidied up afterwards. I'd have no hesitation in recommending Westflow.

Contacted for the first time to replace a leaking valve after receiving an extortionate quote from a different company. Darren was very helpful over the phone and booked the job in for the next afternoon. Barnaby completed the job promptly and swiftly and the cost was about a third of my previous quote! I will definite use them for any future works.
