Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 11 years on the register also points to an established business rather than a brand-new one.

Westflow

Westflow came to repair two leaks in my house. The more urgent one was in the toilet cistern and a slow leak in the pipework under my sink in the kitchen. I was struck with the professionalism I was reassured on the phone and I received a visit to do the work very quickly. The tradesman got on with the job very quickly and on completion thoroughly checked everything before leaving. There was no mess. It was a very fair price. I was extremely happy with the work and wouldn't hesitate to recommend this company.

Boiler service and repair

We use Westflow for our annual service boiler and also any repairs. They completed the service, identified an issue and once the ordered parts had come up they fixed it. Would definitely recommend.

First class delivery

I needed to remove and replace a kitchen tap leaking into the cupboard below. Westflow responded rapidly and communicated very well throughout, and identified and bought a good model of replacement tap. Gary arrived on time; worked quickly and meticulously; and left the kitchen immaculate after completing the job. I would go to Westflow without hesitation in future for any work within their range, and would recommend them highly to others.

Combination boiler installation and servicing

In 2014, Westflow installed a new Worcester/Bosch combination boiler and since then they have done the annual service and quickly and efficiently sorted out a few plumbing problems that have occurred over the years. I couldn't have had a better service.

Old gas boiler and new gas boiler

Our old gas boiler system stopped working just before the weekend. However, Westflow were booked for a boiler service on the following Monday, 2nd March. The engineer identified the problems and restored the system to working order. But due to other deficiencies (including the expansion tank in the loft) it was decided to get a new boiler and expansion tank. It was a relief that these were available for fitting on 12th March. This was duly carried out. The work was pursued efficiently and the clearing up was exemplary.

Brilliant job on gas boiler

This company is run very efficiently so that they are able to give very competitive prices and get the job done expertly and quickly. I sent photos as requested showing the GC number of the Worcester Bosch gas boiler, the required new part was ordered and the job completed within two days. Both the administrator Darren and the plumber Barnaby could not have been more helpful or shown greater expertise.

Easy to work with

I took a chance to try and find a reliable and experienced boiler service and megaflow check. Jamie came as per plan in a good time frame and helpfully explained how the megaflow worked as he serviced it and the boiler. I'm happy to recommend them for their work and customer service.

West Flow fixed a recurring error fault on our Worcester Bosch boiler.

They were quick to respond and managed to fit us in to their busy schedule to fix the fault and restore our central heating in the middle of the February cold weather. Their prices are reasonable and they are good at explaining the work required and completed.

Great Heating Engineers

Discovered a broken motorised zone valve on Friday afternoon. Called Darren at Westflow who sent Joe round within 90 minutes. Joe replaced valve very quickly and professionally. Great team work at Westflow. Certainly will use them again.

Replaced boiler

I highly recommend Westflow I have used them on multiple occasions as this time it was to replace a boiler. They did it quickly knowing I had no hot water and heating at a reasonable price. Always courteous, on time and honest with their support and advice I wouldn’t use anyone else in the local area.

Cannot recommend highly enough

We can always rely on Westflow to do a good job. They installed a new stopcock. Arrive when they say they will.. Always tidy up after they’ve finished. Lovely team. Helpful. We know that the job will be done properly. Also, they can always be reached by phone or email. If not immediately available, they will always call back fairly quickly.

Helpful, polite & sensible prices. Great service

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.

Reliable, competent and trustworthy

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.

Slick and professional

I have been using Barnaby and his team for 4 years now, and the service has always been very professional. They are always very considerate of my house and go above and beyond to leave everything as they find it. His small team know what they are doing and are happy to explain everything, which makes me feel comfortable with them being in my house. I would highly recommend Westflow to anyone who needs any plumbing work done. It's nice to find a company that you feel has your best interest at heart.

What to check before you hire

Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Verify at the sourceCheck them yourself

Approved plumbers on the free WaterSafe register are vetted, qualified to the water regulations and insured. Check they're listed, or find a WaterSafe-approved plumber near you.

Check the WaterSafe register
Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
