DCB Plumbing, initially, came in and assessed my requirements, and listened to what I wanted. They investigated my choice and came back with a quote to source and install the smart heating control system. On the day of installation they arrived at the agreed time, and installed the new heating control system. They were very professional, courteous, clean and tidy. There was no mess for me to clean up after they left. The Drayton Wiser system they installed was easily connected to the app on my phone, without any problems. DCB stayed until all the app setup was completed and I was happy with the installation. I would definately recommend DCB plumbing and Heating.
