DL Gas & Maintenance Reviews

I’d like to extend my sincere thanks to Donovan Johnson for his outstanding service during a recent gas maintenance visit. Donovan is passionate about his work and went above and beyond to identify the root cause of a boiler heating issue, resolving it efficiently and with great professionalism. His attention to detail and the clarity with which he shared his findings were truly appreciated, reflecting a high standard of service. Additionally, I want to acknowledge Leysan for excellent coordination throughout the process. Leysan was clear and consistent communication at every stage ensured everything ran smoothly, and made the experience seamless from start to finish. Exceptional work from both—thank you! Will definitely recommend your company in the neighbourhood and will be in touch for other maintenance works.

Brilliant experience with DL Gas & Maintenance. Donovan was incredibly thorough - he didn’t just identify the issues quickly, he made sure everything was properly sorted with real care and dedication. You could tell he takes real pride in his work. Leysan was fantastic too - efficient, kind and kept everything running smoothly behind the scenes. A genuinely trustworthy and professional team. Wouldn’t hesitate to recommend them.

A highly recommended company. The person that they sent to fix our boiler was very knowledgeable, kind & helpful person. He showed us what was the problem and how they were going to fix it. They made us feel that we were in good hands.

On time. Very professional. Kept us informed at every stage of the work. Very experienced. Polite. Would have no hesitation in recommending this company.

Highly recommend DL Gas & Maintenance! Donovan installed a new boiler at our flat in January 2025 and the entire process from quote to install was flawless. Everything was explained to help us understand the install, and the communication and service we received was 10/10. Go no further if you’re looking for a quality company and incredible service. Leysan was very helpful in organising invoices and communicating the processes, and the boiler and system clean out has left our house warm and energy efficient! If you are looking for a trustworthy, highly skilled, professional company for your next job - look no further!

Donovan was incredibly helpful and kind! They were quick to respond and came promptly to fix the issue. I would definitely recommend them!

Extremely reliable and came through for us in an emergency. We had a contractors mishap which meant that our gas had to be capped off on the same day, we contacted Don and he was with us within a couple of hours. He did a fantastic job, very diligent, thorough and was also kind enough to talk us curious selves through the process! He also did a full boiler service check for us at the same time which was amazing! Would recommend in a heartbeat! So lucky to have such wonderful professionals in our area!

We had a new boiler fitted by DL Gas Services and the job was carried out by Dean on Saturday morning in a thoroughly professional and efficient manner . The boiler works brilliantly ,fitting carried out with minimum fuss and no mess . I thoroughly recommend this company .

I would like to say that I've just had a complete central heating system installed by DL Gas and Maintenance. I cannot praise them enough. I dreaded it being done, but it was great. Donovan went above and beyond to help me find the perfect radiators. Donovan was polite, courteous and very knowledgeable. I would like to say what a splendid service I received, I had no hot water and Donovan visited very quickly, an efficient job was carried out, Donovan is very knowledgeable on all gas appliances and carried out a complete overhaul to my gas fire aswell. I would not hesitate to recommend DL Gas and Maintenance to anyone. Irene Bonell
