Denner Heating & Plumbing Reviews 70

What started off as a problem with my parents bathroom tap and drain during the cold spell, ended with their boiler being serviced (well overdue) and replacement parts fitted. Throughout the process Jake reacted quickly and kept me informed. The guys onsite were great and took the time to explain to my father what was needed. Great fast service, I’ll be contacting them next year to get the boiler serviced. In a time when you struggle to get a plumber to even return your call Denner are exceptional in their quick response and knowledge. Highly recommend them.

Very impressed with the speed of service and quality of work.Would happily recommend to my friends and family.

Jake & Jason, heating engineers from Denner heating did a wonderful job of fitting my new radiators last December ~ 2024 Very trustworthy, attentive, efficient & reliable.

When my boiler broke down this New Year's Eve (2025) ~ I contacted Jake on New Year's day & Jason came on the 2nd of Jan. 2026 to assess the problem. Spare parts were ordered & my boiler was up & running a few days later.

I felt safe in leaving spare keys for Jason to access my home ~ as I was working away. All my messages & emails between Jake & Jason were replied to timeously & any queries answered promptly.

Many thanks Denner Heating ~ I'm happy to recommend such a well organised & efficient local company.

As always very prompt efficient service from the team at Denner

As a new customer, I was very impressed with the quick response to my issue. The engineer arrived on the same day and stayed to carry out the repair and a much needed service to my central heating. I would highly recommend using Denner Heating and will be using them again in the future.

Lovely to get a courteous, clean plumber at short notice to service the boiler after being let down by another local company,
Good communication and customer service.

First class advice and service. We had a failed boiler which wasn't worth repairing, not only were we given great advice on the replacement but offered different pricing options.
The boiler was expertly fitted the next day ensuring we weren't left without hot water and heating.
Honestly, the best service possible.

Not all heroes wear capes, some wear Denner Heating and Plumbing workwear! Rang the office on Monday morning after my old Worcester boiler breaking down on Sunday evening. The guy on the other side of the phone was extremely helpful and professional, he booked me in for Tuesday afternoon. The team turned up when they said they would and I even received a message to let me know they were on the way. The lads managed to get the boiler back up and running. I know it won’t be long until the boiler stops working altogether because of its age, so asked the lads to get Jake to get in touch to give me a quote. I also want my bathroom remodelled so have asked for them to get him to provide advice and a quote for this too. By far the most informative and helpful visit I’ve had from any heating engineers, the boss should be extremely proud of his amazing staff.

We couldn't fault this company one bit. We had tried a few plumbing and heating companies before Denner. Some just didn't want to return calls; some charged for call-outs, which we paid for, and not one solved the issue or wanted to take on the job after the call out charge. After the first call back from Denner Heating & Plumbing, we were booked in and the job was completed. We were so pleased to have them do our work. Thank you.

Knowledgeable, slick and customer engaging. My boiler is old so benefitted from Jason's experience and allowed trainee Lewis to get direct experience of an old style boiler. Jason also explored an additioanal issue and advised accordingly. Evidently a good working relationship between the two men.

Am in the midst of the very stressful process of moving house. Excellent, prompt and reliable service from actual human beings kept me (partially) sane
Thank you Jason, Keiran + co

Excellent service from when they came to sort out a boiler problem . They were efficient professional and thorough and I can thoroughly recommend

Had a new boiler installed including conversion from open vented CH and gravity fed HW to sealed system with combo boiler.
Jake and the team are professional and extremely helpful/polite from start to finish. The install engineers are a credit to the company.
Highly recommended local company with great communication.

Our back boiler wouldn't start so i contacted Jake at Denners.
Jake had one of his engineers out that day to look at it and sorted it out straight away.
We have been thinking of replacing the back boiler so jake came around the next day to do a quick survey and within hours he gave us a quote
Thats it scheduled for one weeks time.
Very happy with the service so far from Jake and his team.

Excellent service installing new oil boiler and pipework for my elderly aunt. They also flushed out the existing radiators and put new valves on them. They were efficient, friendly and tidy. Highly recommend them as they also kept me informed of progress and dealt with issues in dealing with a heating system that hadn’t been touched for decades! Thanks Jake, Jason and Lewis.

Had our central heating system converted from solid fuel to calor gas the guys were great they worked non stop brilliant.had the whole job done in three days.
Can highly recommended Denner heating and plumbing.

Everyone very polite, but can't review work as waiting for wor to be carried out next week.
