Mark was great, from beginning to end, and the quote was very keen on price. The workmanship is fantastic, Mark was thorough, tidy, and quick with the install. I think its important in this day and age that tradesman are seen as trustworthy and I can say that without question Mark is a trustworthy tradesman, who I will be recommending to family and friends.

A professional service from start to finish. He calculated the cost of a new boiler installation for several different makes and advised which would be the most suitable. He kept the work-space immaculate and I felt very comfortable having him in my home. The new boiler is fantastic. Overall, I would recommend Mark 100% and I will continue to use him in the future. If you want someone that you can trust and who is reliable, then choose Chelmsford Boilers.

New combi-boiler and radiators installed. Excellent job by Mark who is very professional, hard working and a very good, experienced plumber. Pays a lot of attention to detail. Also very good price.

Desperately needed a boiler as both our old one and the immersion heater had packed up, leaving us without hot water. Rang up mid-morning Tuesday, Mark came out that evening and provided an estimate a few hours later; new combi-boiler fully installed with old system removed by the following Saturday, just 4 days after my initial phone call. Fantastic customer service, top marks for efficiency, professionalism and tidiness, wouldn’t hesitate to recommend.

Mark has installed us a fantastic brand new boiler and his advice both before, during and after the installation has been really helpful. He really cared about leaving us in a position to benefit from the most efficient installation. He was sensitive to fitting in normal family life and great with our dogs! We will be using him again and highly recommend.
