Safety, security, performance. Honesty, trust, integrity – our commitment to you

Since 1996, SJD has proudly developed an enviable reputation for always doing the right thing for our clients. SJD continually invests in our people to ensure our site and office teams are fully equipped to coordinate and deliver successful projects, often in complex and challenging environments.

We offer responsive electrical design, installation and maintenance services to local businesses, full MEP packages for main contractors and can also act as principal contractor for larger projects.

Small business values, large business expertise

From concept through to design, engineering, installation and maintenance, our work is carefully planned and carried out to the highest technical standards by our qualified and competent team. We bring not only our values and commitment to every project, but also a breadth and depth of expertise and resource often only seen in much larger firms.

Our regular direct clients include Cranfield University, Midsummer Place Shopping Centre, Niftylift, MK University Hospital and many other local businesses. We also specialise in prison improvement projects spanning several years, providing consultancy support, design and intrusive surveys to develop tender specifications. With high levels of repeat business, SJD is the safe choice for your project, no matter the size and especially where there is uncertainty regarding the engineering solution required.
