We contacted Duncan late morning about our boiler issue and although he was of course working on another job at the time he still managed to address and resolve our issue by the end of the day. Great communication, friendly, professional & fair prices.

Duncan was quick to come have a look at a potential problem regarding a leak in our below neighbours apartment. He put our minds at ease and explained this can’t be pinpointed on us as a root cause and no signs of leaks. Friendly and quick service at a really reasonable price!

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!

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

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.
