“Very hard working, knowledgable and reasonable price company. Elias arrived on time, he was straight to the task and fitted my new boiler with care. He is a great, honest and funny guy. If you’re looking for a new boiler installation, look no where else. These guys are professional and reliable.”

“I can't recommend Dan highly enough. I thought I needed a new boiler as there was so much wrong with it but Dan did his magic and 18 months later its still working fine. I had him on an urgent call out a few days ago but he soon had the system back to normal with a bit of a service. Many thanks Dan for giving us peace of mind with our heating system.10/10”

“Kyle recently changed two radiators for me at my flat and replaced a leaking mixer tap on my bath. From start to finish was a great experience with Kyle. He has brilliant communication and advises clearly and thoroughly on which products will work best and why, for the job you are having done. Prices are clear from the outset and he'll keep you updated on any changes. He really knows his stuff and did a fantastic job at my place. I'll definitely be hiring him again, plus recommending him to others. Natasha Bradshaw”

“Ashley from Ickenham Heating was not able to come out but sent another colleague within the day I contacted him. I had a wonderful experience and full diagnostic from his colleague Chris who went through everything fully and explained all the workings of the heating system in a a very thorough way and made non pressurised recommendations. Charged a very small call out fee (unlike most) so cant thank them enough for their stress free response. Many thanks Ashley for sending Chris.”

“Recently moved and had issues with my hot water fluctuating between hot and cold. I spoke to several plumbers, but most wanted separate charges for diagnosis and boiler servicing, which felt unreasonable. Simon stood out. He diagnosed the issue over the phone (faulty plate heat exchanger) and didn’t charge extra for the inspection. He’s genuinely sincere, took the time to explain everything clearly, and made the whole process stress-free. His rates are fair, he’s responsive, and clearly takes pride in his work. I’ll definitely be using him again and would recommend him to anyone looking for a trustworthy plumber. Thanks mate!”

“These guys are the real deal. After a few other plumbers to come sort our issue out who never turned up. These guys came down straight away. Chris was the initial contact who was extremely professional. The issue was sorted in a couple days after waiting for replacement parts. Their work was very tidy and neat. Their pipe work was impressive and neat. Hands down a great team and company. Not many of these around nowadays that take pride in their work. Thanks Chris and team…”

“I was looking for a reliable and competent plumber and found Mr Delmi and I must say I am very pleased to have met him as he was very efficient in arranging and completing the task, assisted me with arranging for a tiler at the same time. The whole project was as smooth as I could wish for and I highly recommend him to anyone as I know I will contact him for any future work to be done on my house.”

“Look no further... Use these guy!! I found Westflow online after looking at their reviews. I am in Canada and had an issue with my flat there. Communication was prompt and efficient and they did exactly what they said they would do. After referring me to another company that did some things that they didn't, Westflow returned to site, diagnosed a small issue and corrected it right away. Pricing was very reasonable. I would have no hesitation referring them to anyone and using them in the future. Barnaby's approach was calm and really helpful and that cut down on a lot of stress dealing with issues from out of the country. Thank You Westflow”

Great service in replacing our old boiler, they were quick to respond to our query, communicating clearly about the process, making sure their work was done to a high standard, double checked everything was correctly working and even went out of their way to fix a small non related issue that came up while he was on site. Very friendly and competitively priced!”

“Peter undertook a complete boiler and gas inlet pipework upgrade in our garden flat, his approach was meticulous, professional and he came in well on budget. He also patiently answered our varied questions about products and what was required for our refit when initially drawing up a short list of potential contractors. Peter did not rush when on the job and took a pride in the task at hand. I would happily endorse his services and intend to use his skillset again in the future.”
