New boiler installation

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 is always extremely punctual when performing annual service. He is always polite and thorough, explaining the tests he performs. He sends annual reminders as well.

DT Heating installed the boiler in my house 8 years ago and I've used them every year since to service it. I would highly recommend them to anybody, they are professional and efficient. They reply to emails or messages promptly and arrive for appointments when arranged. 10 out of 10.

I have just had my 6th service by Calum. My system is unvented and in my new property the previous plumber had installed the cylinder without an expansion tank. This is now safe thanks to Calum. Never had any issues when arranging services. Always on time,polite,clean and great prices.

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.

I have used DT Heating for about 4 years now. Duncan and Callum are 2 of the most genuine trades people i have ever met. I have my boiler and fire service completed every year about this time. Callum turned up on time and got on with the job. Over the years i have had a number of jobs done besides the regular service. My boiler has been moved from the loft to kitchen,I have had a radiator added to my current system, Ihave had a Surestopped added to my water supply and i have had a cooker fitted. DT Heating come highly recommended from me and my family I would not go to anybody else. I always find them approachable, reliable and all at a very reasonable cost. I would not hesitate to contact them if i need anything sorting on my heating system. Thank to Duncan and is team.

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.
