My shower unit leaked in the base through to the ceiling below, causing damage and collapse of the ceiling. The thermostat in the control unit was also broken and needed replacing. Barney and his team replaced the shower and retile the shower area as well as arranging for the ceiling to be plastered and painted. Throughout the process I was given a full explanation of the issues and all the options that were available to rectify the problem. The team were excellent, they were very reliable and they always left everything tidy and clean. I have since recommended Westflow to other friends, who have very happy with their work and service. I would not hesitate to recommend them, they are an excellent company with a strong service ethic and a focus on delivering quality work.

I have used and experienced many plumbers over the years but I contacted Westflow Ltd and I was impressed. From first contacting them Barnaby arrived on time and was very smartly dressed. He got straight on with the work and carried out the servicing of my boilers and central heating system. I would honestly recommend him a very pleasant man.

I contacted Westflow about a problem with our hot water flow and temperature control. Barnaby did not quit until the fault was found (a faulty mixer valve). Subsequently, we elected to hire Westflow to install a new shower and accumulator to improve our water flow. I can't fault him and his team. The quote was reasonable, communication excellent, the job was done on time, the team worked considerately without mess, and were very polite. I will definitely use Westflow again and thoroughly recommend them for all plumbing and heating jobs.

I have been a Westflow customer for about 7 years, mainly for boiler maintenance at different properties. I would recommend them to anyone who is looking for a trusted and skilled tradesperson. Great communication, easy to work with, attention to detail and reliable. Barney went above and beyond and offered to bleed my radiators for me at the same time as servicing the boiler, for which I am very thankful.

Very good service from Westflow, Joe fixed my shower promptly and did a very professional job. I have no hesitation in recommending Westflow for sorting out plumbing problems. They give a precise quote for the job and turn up when they say they will and let you know if there are any delays.

Excellent and efficient service. Arrived on time and competently completed the work. Fault identified and ideal boiler company informed (they will replace part as boiler is within guarantee).

Boiler was due a service, but then started to develop a leak. Emailed Westflow and Barnaby got hold with a slot the same day. Engineer was prompt and got straight to work and diagnosed the issue within minutes, assured me it was nothing disastrous and had it all fixed and serviced within 90 mins. I like the set of photos that came with the invoice showing the steps of the service, the old broken piece and the replacement side-by-side (no chance of being conned for "replacing" something that's not!) and the stats from the device that measures the gasses. That's new to me.

I called Westflow about a blocked sink in my rental property that had been an ongoing issue for some time. Barny made arrangements with my tenant to come out the following day and had it cleared in no time. Very happy with the service and price for the work. Highly recommended.
