Who We Are

 We are a building services design practice with over 30 years’ experience designing in custodial, commercial, residential, retail and healthcare sectors.
The company was formed by Colin Harding who remains Senior Electrical Partner in the organisation. He is supported by Colin Hoare as Senior Mechanical Partner and they are surrounded by a close-knit Senior Team and team of engineers. People are a large part of what makes a brand successful and we’re proud to have a committed set of individuals.
Over this time we have built a wealth of knowledge in the design of mechanical, electrical and building services solutions for these sectors. Working in the built environment, from commercial office fitouts, upgraded services in prisons, to high-end designer retail stores, CJ Design has completed a portfolio of outstanding design and fitout projects.
With passion and hard work we have built our reputation for designing and managing implementations to the highest professional standards, with outstanding service. The company is recognised by both customers and key partners for it’s technical ability and professional service delivery. We enjoy great customer retention.
Our values reflect those of integrity, trust, quality of design and service delivery. And, importantly, a deep understanding of our Clients’ needs.  This has allowed us to not only gain a better understanding of what drives their needs but also helps to broaden an understanding of the advice we can offer at a much earlier stage in the design process. We have therefore within CJ Design endeavoured to encourage an attitude within all staff to ask the Client “how can I get to know your business and its functional needs better?”
We are actively committed to reducing the carbon footprint of the UK building stock and work hard to deliver sustainable solutions far beyond the guidelines, whilst still working within the cost plan.
