Prioritized our broken boiler

The water leak was identified quickly and part sourced. Next day fitted. Boiler service flagged up a couple of rusty parts - given cost of new parts and age of old boiler >10yrs we opted for a new ECO make. Job done quickly with great communication and left very clean and tidy. Reasonably priced great service.

Change leaking tap

Ciaran responded very promptly to our callout to change a severely leaking bathroom tap. He removed the old tap, which was a tricky removal as there was heavy corrosion underneath and the tap had to be cut out. He supplied and fitted the new tap, which is working great, looks much better than the old tap, and I am delighted to report there are no more leaks. Ciaran left the bathroom spotless after he finished the job and I would not hesitate to recommend him as an excellent plumber.

Excellent plumbing company

I can truly recommend Stelfox Plumbing. I recently had a new Combi Boiler installed, and Ciaran is probably the best engineer I’ve had the privilege to work with. His work ethics & attention to details were perfect. He removed unnecessary old piping to install a cleaner & much more efficient system. It’s very rare these days to have a plumber like this, these types of work ethics used to be around 40-50 years ago. So it’s a breath of fresh air to know you’ve chosen the correct company. If you have any plumbing needs, call Stelfox because you’ll be happy you did. Thank you.

New Radiators

Our 4th time using Stelfox Plumbing & Heating, this time to replace all the radiators in the house. As expected, we were extremely pleased with the final result. Ciaran paid great attention to ensure the radiator placement was perfect and that the pipework was symmetrical. Certain radiators were trickier to replace than others, but despite the extra work, Ciaran was very fair with the pricing. Would highly recommend and will definitely use again in the future.

New Shower Replacement

Ciaran recently replaced a seized shower unit built into the wall. He did so with great care and managed to match the new tiles with much older tiles. Ciaran is very professional and his service is efficient. We have used Ciaran numerous times for drainage issues and repiping and cistern replacement and the service has been fantastic! Highly recommended for any plumbing works!

We would definitely recommend Kieran at Stelfox, he did everything he said he would, when he said he would it. He viewed the job on the Friday was back after the bank holiday Monday to fix it. The work was carried out in a highly professional manner, he was on time, clean and tidy and got it fixed for the price agreed. What more do you want. 👍🏻😀

New gas pipe fitted for a new gas hob
Customer Service

I needed a gas supply to a new hob which is being fitted shortly. I telephoned Ciaran (Stelfox Plumbing and Heating) and left a message for him asking him to call me back which he did promptly. We arranged a date and time for the job. On the morning of my job, there were traffic problems which delayed Ciaran slightly but he texted me to let me know he was stuck in traffic and that he was on the way. I really appreciated this because then I knew he was on his way. No other tradesmen I have engaged in the past has done this and often I have been left waiting and wondering if they were still going to arrive. Ciaran installed the new gas pipe for the new gas hob. The job was neat and fitted against the wall perfectly even taking into consideration the wall was wonky as it is a period property. Ciaran worked quietly and cleaned up and hoovered after he had finished. I have engaged many plumbers and heating engineers over the years and I can honestly say that Ciaran is the best. He is polite and listens to you and is very professional in every aspect. He is very respectful to the property and has always done a fantastic job for me every time I have needed work done. I thoroughly recommend Stelfox Plumbing and Heating.

Thank you so much for taking the time to leave such a detailed and thoughtful review. I’m really glad I was able to help with the installation of your new gas supply and that you’re pleased with the result. Communication and reliability are very important to me, so I’m delighted to hear that keeping you updated on the day made a difference — I know how frustrating it can be to be left waiting and wondering. It’s also great to know that the pipework fitted neatly, even with the challenges of working in a period property, and that the care taken with tidiness and respect for your home stood out. I truly appreciate your kind words about professionalism and the trust you’ve placed in me over the years. Feedback like this means a lot and motivates me to continue delivering the highest standards of service. Thank you again for your recommendation — it’s always a pleasure to help, and I look forward to being of service whenever you need me in the future.
