About us

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 specialising in high-quality pipework installations. In 2015 CPS became a full building services provider founding its electrical offering with a strong focus on delivering a quality installation.

This discipline and determination to deliver high-quality installations is what motivates all of the CPS team today. With a team of over 170 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 £35 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. In 2021 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. More recently CPS secured the award for High Growth Business of the Year at the SME Cambridgeshire Business Awards 2021.


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 Addenbrookes Charitable Trust; we hold an annual charity golf day where all proceeds support the Trust - CPS has raised just under £70,000 in the last three years for the Trust. We are also committed to supporting local sports clubs and teams, since 2018 we are delighted to have supported Sawston and Babraham Cricket Club.

Mark project managed the refurbishment and we are very pleased with the way it was handled. The new space meets all our requirements and has been completed on time. When it was handed over to us the space was clean and ready to use.

Heating a medieval church for modern comfort is a very difficult thing to do. CPS designed and installed a system that is flexible and remarkably responsive.

CPS carried out the works quietly and efficiently with little or no inconvenience to anyone. The College staff found them very easy to deal with and the finished job is superb.
