John went out the way to resolve our boiler issue over the weekend. He was very helpful in the hour of need and fixed the boiler issue efficiently. He is very polite and professional and can be trusted 100% with his work. We are glad we found him.

John is really polite and respectful, been using his services through my agent for over 6yrs, consistently prompt, reliable and approach each service with sensitivity, professionalism and timely manner. Highly recommend.

We were pleased that we took the recommendation of the previous homeowner to use John, as he is a lovely man and did a great job. Highly recommended - and already booked in for next year!

John bent over backwards to help me when water from my immersion heater leaked into the house electrics. He was extremely busy with other work but arranged for his colleague Chris to come out the next day. The whole job was sorted in 24 hours, with no fuss. He and his colleague were reliable, respectful and professional at all times. I wouldn’t hesitate to recommend him to anyone.

Have used John Mac heating for many years servicing a boiler and recently installing a new one together dealing with miscellaneous plumbing issues. The service is always very reliable and of high quality and competitive. I would have no hesitation in recommending him

Jon changed our boiler for a newer one and we are really happy with the professional service we received. The boiler was installed relatively quickly but refused to work. Jon stayed well into the evening on a Saturday trying to resolve the problem. Eventually the issue was resolved and we are very happy with our new condenser boiler.

Having known John Mack for over 5 years, Our experiences with him has been excellent, he and his team are very professional and has always completed his work promptly. He is very personable and I would have no hesitation in recommending him to anyone who is looking for a reliable gas engineer.

Great service with a practical approach. Really pleased with the install and my annual services which have been done. John is a friendly, positive character who always does a clean, efficient job. Very pleased with help and advice I've recieved over the years. I have no hesitation in recommending him.

In my opinion John is an excellent plumber and he has helped me out with a number of issues over the years. Whether it be a problem with my boiler, waste disposal or heating. He has always provided a prompt response to any plumbing emergency. Thank you !!

John has been looking after my boiler, taps, shower and pipes for many years. Always courteous and professional, explains what he is doing, and leaves things tidy. I have no hesitation in recommending him.
