Heating Controls Online is rated 4.90 stars by Reviews.co.uk based on 2484 merchant reviews
It was easy to find the part I required on the web site and it was delivered promptly after the order was placed. The service was excellent.
Very good service, fast delivery.
Bought an actuator and it was delivered as stated on time. Unit went faulty and was returned with no issues and another replacement sent out. I cannot praise Heating Controls Online enough, for their service, and would recommend anyone to do business with them without a second thought.
