CPS Building Services is a dynamic and innovative building services contractor based in the heart of Cambridgeshire.


From the very start of our journey, excellence in delivery and service has been integral to our life as a company. CPS (originally known as Cambridge Piped Services) was founded in 1995 by James Rust, a Cambridge Engineer who built his reputation on delivering high quality pipework and boiler room installations to schools, colleges and businesses across the region.


This discipline and determination to delivering high quality installations is what motivates all of the CPS team today. With a team of over 100 in-house employees, ranging from Project Managers to specialist Engineers, we can provide a comprehensive packaged solution for our customers’ building needs – from design to installation, refurbishments and ongoing maintenance.


It’s an approach that has led to sustained growth and exciting new developments for CPS. With a turnover now in excess of £25 million, we have times our Employees by 6 in the past five years, and we are continually seeking to bring the very best people to work alongside us.



As a company, CPS believes in doing things differently. This means we are always looking to innovate our services in order to create better service and value for our customers. Recent innovations include a fleet of mobile boilers that can be deployed at short notice to supply hot water and heating in an emergency or as a planned refurbishment. And an advanced CRM system which stores our clients system and plant details making life easier for our clients when they call us for support.



At CPS we are very passionate about our team, we also put great emphasis on supporting the future of our industry through our work with Apprentices. We were awarded “Employer of the Year 2016” from Cambridge Regional College and we were finalists for “Employer of the Year 2018” in the Cambridge News and Business Excellence Awards. More recently CPS won "Medium Business of the Year 2020" and Managing Director Liam Connelly won "Business Person of the Year 2020" at the Cambridge Live Business Awards 2020.



We also believe that successful companies should give something back, both to the local community and in particular to people in need. CPS is a committed long term supporter of the Alzheimer’s Society; we hold an annual charity golf day where all proceeds support the society. We also donate a proportion of our company profits to the charity on an ongoing basis. We are also committed to supporting local sports clubs and teams, since 2018 we are delighted to have supported Sawston and Babraham Cricket Club and our headline sponsors The Cambridgeshire Area Golf Union County Open.



CPS has grown rapidly in recent years, since 2018 our number of Employees has increased by 108%. In 2020 CPS acheived our milestone of over 100 Employees. We are always looking to recruit the best talent in the industry to partner with us. One of the ways we do that is by focusing on people. We love to see our Employee’s progress, so we have a company-wide emphasis on training, and on supporting and promoting our own people wherever possible.
