My landlord sent Duncan as I was having a few troubles . Duncan was so professional and went above and beyond . Gas certificate done and wireless thermostat fitted. Would highly recommend and understood my needs and some issues was causing my daughter with ASD to have meltdowns he totally understood. I would definitely recommend Duncan and look forward to working with him in the future

A friend recommended having my new boiler fitted with Calder and now I am passing such a recommendation on to you! From start to finish, the service I received was second-to-none. Communication was timely and efficient and the work was completed in no time at all. Lovely people who really care about getting the best for their clients… thank you!

From start to finish, Duncan has been first class. Him and his team work very hard to an excellent standard. Duncan gave very good supportive advice. We have been very happy with a complete boiler change and all new radiators all at a competitive price.

Duncan supplied and fitted new radiators throughout my home as well as changing the pipework. No job was too big and always arrived on time with a smile. Job has been done to a fantastic standard.

Duncan and his team did a marvellous job installing a new boiler and 6 radiators. They completed the work within a day, leaving the house clean and tidy and were all friendly. Duncan was very good to deal with from the outset. He communicated well and went out of his way to source specific radiators. A good job at a reasonable price. Thank you.
