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.

Callum arrived on time snd carried iut a thorough service on our central heating system. I have always used a national company to this. The service they provided usually lasted a maximum of 15minutes! Callum checked every aspect of the system and dpent two hours doing so. He was polite and efficient and I would have no hesitation in recommending DT to others.

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 came to replace a combi boiler for us and also carried out a landlords safety check on one of our properties. It was really refreshing to have someone who came when they say they will (even sending us a text 5 minutes before he would come) there was no hard sales, just solid and knowledgeable information. I would highly recommend him to anyone.

DT Heating did a great job on a boiler replacement, installation of new radiator and installation of a shower. They turned up on time, tidied up after themselves and installed the equipment well. We now have a toasty warm house. Some days they worked for 12 hours to make sure the job was done with minimal disruption.

We have recently had a new boiler fitted by DT Heating. We are extremely happy with the result and would definitely recommend their services. Bearing in mind it wasn’t straightforward and involved the removal of a combined back boiler and gas fire. Duncan and Calum were very professional, knowledgeable, courteous and very mindful of keeping the disruption to a minimum. Thank you DT Heating.

Big apologies for late review. Amazing service! Boiler Duncan and Callum installed (and recommended) has made house a different place: warms up in no time. They kept us informed every step, were always exactly on time and worked every minute. Had to relocate boiler so a difficult job. D and C left everywhere tidy when they finished. Two really professional, nice guys. Thanks!

Apologies for late review! Duncan was polite, friendly and very efficient. He left everywhere clean and tidy after completing the jobs and I was very satisfied with all the work he has done for me. Everything was done on time and to an agreed budget. He was punctual and would ring beforehand to say what time he would arrive. I would certainly recommend Duncan and will definitely use him again.

I had DT Heating fit my boiler several years ago and they have been coming back ever since to do my annual inspection. Their useful annual reminders that my service is due is great as I always forget. They clean up after themselves and provide advice when needed. Everything is still working from 2018 and any issues these guys are quick to respond to help sort it out. I would recommend to anyone else looking for a reputable company.

Excellent service from DT Heating. Been having boiler problems another plumber had failed to diagnose. Communication to let me know they were on route. Polite and friendly manner whilst here. Very professional and thorough diagnosis of the problem. He even brought a dust sheet to keep the mess to a minimum. Things like that really do go a long way to leaving a good impression. Quote given and repair booked whilst on site. Would highly recommend.
