Westflow were quick in responding to my request, stuck to the time slot given and even messaged me to let me know they would arrive in 30 mins. The plumber was efficient and gave me advice on another matter in addition to replacing my leaking outdoor tap. Little things matter like the fact he took his shoes off at the door and was extremely polite. I have already asked for them to come back and service the boiler. Highly recommended.

We've had boilers installed at 2 separate properties with Westflow, we've also had radiators upgraded and several smaller jobs completed. The work, the communication and the service in general is excellent. Highly recommended.

Barnaby was fantastic from start to finish. I wasn't able to give much notice for the work as it was dependent on the work of other tradesmen. However, Barnaby was accommodating, reliable and very professional. I would highly recommend his company.

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.

Responded on a Saturday within 20 minutes. Tried to diagnose over the phone and get hot water running as quickly as possible. Due to the problem this wasnt possible. Barnaby kindly came out on a Sunday morning to solve the problem. I could not recommend him any more. No fuss, straight talking great professional.

Annual boiler and central heating service

Westflow installed all the radiators and related elements of the central heating system in 2016 when the house was completely renovated. His firm has continued to carry out the annual service since then. Barnaby and his staff are very professional, helpful and reliable. They give a guide price for the service and that is what we have always paid. They communicate their anticipated time of arrival and arrive when they say they will. Their workmanship is excellent and we have never had to call them between services to carry out any repairs. We would recommend them unreservedly.

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!

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.

So reassuring to have a specialist you can rely on

We have asked Barney and his team to help with multiple different tasks (from plumbing in new appliances to repairing the boiler) and it's always such a breeze. The communication is really good - I particularly appreciate the text 30 mins before arrival, so you're not waiting in all day - and the team are always really friendly and helpful. Everything is completed to a high standard and we've never had to have a repeat visit on any work. Barney has twice helped us out in an emergency - so it's very reassuring to know that, if we ever had a plumbing or gas issue, Westflow will be on it (and for a reasonable cost too). The team are all reliable, clean, knowledgable and diligent. We recommend Westflow all the time - they're a rare find!

We called Westflow, having previously used them for a boiler installation in our previous home. Within a day Westflow came and traced the fault replacing the faulty part. As before, the owner of the business was polite, diligent, thorough and clean. His charges were reasonable. I would confidently recommend using them if required, I certainly will if or when the need arises.
