"I am now on our second project with MJD; their family-run business has a wealth of knowledge with experienced and specialised staff. The supportive professional approach was provided by dedicated staff who provided support and technical know-how to get it right the first time. The design development, from stage 3 drawings to problem-solving, was some of the best I have experienced in many years. My first project with MJD was a complicated project in a live school in London, where expectations of the design were huge and constantly being changed. The team were vigilant in their installation and quality control, resolving issues as they occurred with a partnering/ teamwork approach to the finished product. I have never experienced such a complicated compact plant room, only possible due to the hard work of MJD. My current project with them is now drawn and well-coordinated with other trades and the structure. I wouldn’t hesitate to recommend them as a valued asset to any team"

"Over the past four years, I’ve had the pleasure of working with MJD on numerous decarbonisation projects, and they’ve consistently proven themselves to be a reliable and highly skilled partner. Their team brings a wealth of expertise in both mechanical and electrical services, always delivering work of the highest standard. Whether it’s a complex installation or a fast-paced refurbishment, MJD approaches every task with professionalism, attention to detail, and a proactive mindset. Their commitment to quality, safety, and client satisfaction has made them an invaluable part of our project delivery team. I look forward to continuing our successful partnership."

"MJD have undertaken the mechanical works on several projects I have managed and are currently carrying out the upgrade, refurbishment and new build at Gloucester road Medical Centre, I have always found MJD to be very professional and proactive, there engineers are reliable and conscientious there work is very clean and methodical, wherever possible I will use MJD on future projects, I would recommend MJD for all types of mechanical works."
