A reliable plumber who we have used on several occasions. Always tidy and good quality work. He fitted a new boiler at our warehouse a couple of years ago, and the work was highly satisfactory

I've used Stelfox before and when our company experienced problems with hot water we asked them to come and look/quote. We were very impressed with their clear communications throughout and their prompt action on an old boiler, and advice and help on which size boiler to chose. We went with Stelfox and have been very impressed with the standard of work. Clean and tidy and the minimum of fuss.

Stelfox completed a full bathroom refit to time and at a good price for the work carried out. They kept me informed with any issues that arose. Very easy to deal with and everything ran smoothly and to the time scales advised. Would definitely use them again for my plumbing needs.

Hidden Costs
Customer Service
Quality
Value
Feel like I was overcharged off by Stelfox Plumbing and heating. Added £1600 to my invoice for work that was never discussed and a price for the work that was never given beforehand even though it was a binding quote. He then blamed the majority of it on the tiler for not giving an invoice till the work was complete. Also charged another £555 for bigger piping to run to the boiler. When I asked him why this wasn't spotted when he came round to give me a quote his reply was that he didn't know until he took the boiler off the wall and a pressure drop test was carried out. I disagree as he told me about the piping on day one and asked if I wanted it doing before even starting on the boiler. The whole reason for going with a Which trusted trader is that everything is up front and honest. I'm absolutely disgusted that Stelfox is a Which trusted trader and have now lost confidence in them.

The trader replied (on 18/08/2026)
Thanks for your review. We’re sorry to hear you feel this way. We would like to provide some clarification. The quote for the 1st job (2 x full bathroom refurbs) included TBA items relating to tiling. These were discussed on site with you before work continued. Once the job was complete, you queried the additional costs and we provided a full breakdown and explanation. You were given the opportunity to discuss this further, but no further concerns were raised and you proceeded to pay in full. Following this, you booked a 2nd separate job (downstairs toilet refurb). No issues were raised about the 1st job before or during the 2nd job, it was only until after the 2nd job was fully completed that you raised a complaint about the costs for the 1st job and stated that you would report the matter to Which? unless we deducted money from the 2nd job’s invoice. Re the boiler pipework, this was explained to you, including the impact on the warranty if the incorrect pipe size was used. You agreed to this additional cost via text before works commenced. Your review does not reflect the facts or the positive feedback you gave during both projects. We always aim to be transparent, fair, & professional, & we are disappointed that this review does not reflect the full context of the work carried out or the steps taken to resolve your concerns. We are more than happy to discuss this with you further.

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.

I really appreciate your kind words about the service and pricing, and I’m pleased you’re happy with the outcome.
