Our boiler literally blew a gasket no heating hot water. I emailed Denner they phoned the same day spoke to my husband. I took photos of the issues. Denner technicians turned up the following day with replacement parts and we were repaired and tested. We have a repair plan with them as they complete our annual service.

they did everything well there was a gas leak which they fixed by fitting new gas pipes they were very efficient I would recommend them

Very professional, tidy work

Excellent - arrived when they said they would and were very polite. Unfortunately our boiler needed replacing but at my request they gave a competitive quote for a new one. The new one was then fitted by them at short notice and despite the job being more difficult than anticipated, and taking longer there was no additional cost. Would recommended them and will be getting the back to service the boiler in a years time

Great company excellent work , would recommedend and definetly use again

I recently moved into a house which, to say the least, has a few quirks in terms of the plumbing, electrics and the workmanship of previous trades. Enter Denner Plumbing & Heating — in the form of Callum, Lewis and Jason. Between them they installed a brand new gas combi boiler, resolved plumbing issues affecting the taps and washing machine, and identified and advised me on additional circuitry that had incorrectly found its way into the boiler’s fused spur. The difference has been transformative. What particularly impressed me was their methodical approach to troubleshooting legacy problem
