We have used DT Heating several times for boiler service and other central heating work, they gave you date and time, and text ahead on day to let you know when they expect to arrive. Callum did our boiler service and cleaned out filter, plus he sorted the stuck pin on our kitchen radiator. Polite, friendly and excellent service.

He was polite and efficient and I would have no hesitation in recommending DT to others.

I’ve used DT a few times over the years and they’re throughly reliable, local firm that’s value for money. I’ve had no problems or concern about them, just praise. They always have an apprentice too, which is good to see them training the future. I’d definitely use DT again.

Duncan and his team have installed a new boiler, radiators, new piping and laid my lead pipe replacement with new stop cocks. I've used Duncan twice now to fit a new boiler, in different properties. Never had an issue with my previous boiler, it was still working perfectly fine 8 years after installation when I sold the house. DT heating notify you of annual services and come do them. For our new house we had some tight deadlines to work with as we were moving into a house undergoing renovations. He has come out and spent long days making sure we had heating when we desperately needed it. The team doing the renovations have also all said they enjoyed working with Duncan, clear communication and helping each other out along the way. Will continue to use DT heating for years to come. It's nice seeing the business grow taking on more apprenticeships.

I have used DT heating twice now, the first time to install a new room thermostat and the second to service our boiler. Communication was good with dates and times for the work arranged to suit us, and on the day I received a text letting me know they were on their way just prior to the arranged time. The work was carried out professionally, timely and we were happy with the price. I received confirmation and invoice receipts via email immediately after the work was complete. Duncan and his apprentice were very polite and friendly, left everything tidy and I would have no hesitation in using them again. Highly recommend.

Used DT Heating after they had installed radiators at my in laws earlier this year. Callum came and inspected boiler and tank and advised on work needed which was booked in 2 weeks later. Callum completed work and no issues since. I'm using DT heating again to replace radiators. Highly recommend.

My partner and I are in the process of purchasing a house and we required a boiler service to be completed. We spoke with Duncan initially and he arranged for the service to be completed quickly, taking the time to reach out to our estate agency and find the most suitable time for our venders. The service was booked and completed within a few days of the initial contact which we massively appreciated. Callum carried out the service on the day and provided us with an in depth report and an invoice for the job, everything was super easy and we are extremely happy with the overall service of the business. We will definitely be using DT Heating Ltd again, thank you so much!

We had a leak on our old boiler. Callum came round and assessed the problem which meant a an expensive repair. We decided to get a quote for a new boiler which Duncan supplied promptly. Price was competitive and comprehensive so we decided to go ahead. Duncan arrived as promised and took his time to protect our carpets and furnishings. All work was carried out effeciently. Duncan left the house clean and tidy. We are very pleased with the new boiler (no leaks). We would certainly recommend DT Heating. Duncan and Callum were both very friendly and helpful.

Callum put in a very long time of intensive work to service our boiler, replace the gaskets and fit a new flow switch, and then to test the entire system thoroughly. We were very impressed by his focus on getting the tasks done, even though it meant he had to work until quite late (about 6:30pm) before he began putting all his equipment back into his van. Looks like he’s done an excellent job - thanks Callum.
