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 problems rather than simply carrying out the boiler installation and leaving the rest. They were professional, clear in their explanations, and thorough in ensuring everything was left working properly.

All in all, an excellent job and a very reassuring experience.

Callum,who fitted my new kitchen tap,was a nice friendly guy and took no time at all to do the job in hand . The price was reasonable and because of a cancellation the job was done the same day as we got the quote .I wouldn't hesitate to use the company in the future.
