Very quick response to enquiry and attended the same day. Explained everything throughly and repaired the central heating the same day. Very pleased with the service
I had no hot water or heating and C&C were able to fit me in that day and repaired the same day very rapidly. Very helpful, quick and professional. They definitely saved us from a cold night and an unhappy baby! I wouldn't hesitate to use them again.
Leak of toilet system, replaced parts. Replaced problem very quickly and efficiently.
Reliable, helpful and trustworthy. New hot water tank installed, new boiler fitted.
Boiler repair and cooker fitted. Quick and good quality.
I would highly recommend Denis and Andy, as they are very friendly and are very knowledgeable and do a great job, and they gave me lots of helpful tips. If you are looking for plumbers that are punctual, and get on with the job, and you want value for money, then these are the guys to use!!
Very pleased.
Always very pleased with the work done.
Denis regularly services our boiler and so when we arrived home from a visit away to find water dripping through the lounge ceiling we knew who to call. He called back within 10 minutes and was with us shortly thereafter to assess what needed to be done (19 yr old element in the hot water cylinder corroded and leaking) and give advice as to how to prevent further water damage. He returned with a colleague the next morning to replace the element and we are sorted! Every one needs Denis Cooper in their contact list, highly recommended.
Cheerful, polite and professional.
