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 180 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.
This approach has driven sustained growth and exciting developments at CPS. Our turnover now exceeds £50 million, and we have increased our workforce sixfold over the past five years. We remain committed to attracting and retaining the very best people to grow with us and deliver exceptional service to our clients.
Innovation
As a company, CPS believes in doing things differently. We are committed to continually innovating our services to deliver greater value and sustainability for our customers. Recent advancements include expanding our expertise in the design and installation of photovoltaic (PV) systems and electric vehicle (EV) charging solutions — helping clients reduce their carbon footprint and embrace renewable technologies. We are also transitioning our fleet to hybrid and electric vehicles, further demonstrating our commitment to a greener future.
Teamwork
At CPS, we are passionate about our people and proud to foster a supportive, collaborative environment. We place strong emphasis on developing future talent through our dedicated apprenticeship programmes, helping to secure the next generation of skilled professionals for our industry. Our commitment to our team and community has been recognised through multiple awards, including “Employer of the Year 2024” at the CIBSE East Anglia Annual Awards. This follows previous successes such as “Medium Business of the Year 2020” and our Managing Director, Liam Connelly, winning “Business Person of the Year 2020” at the Cambridge Live Business Awards, as well as “High Growth Business of the Year” at the SME Cambridgeshire Business Awards 2021.
Community
We believe that successful companies should give back to the local community and support those most in need. CPS is a proud long-term supporter of the Addenbrooke’s Charitable Trust, hosting an annual charity golf day that has raised over £100,000 in the last three years alone. We aim to surpass last year’s total and continue making a positive impact. In addition, we actively support local sports clubs and teams; since 2018, we have been delighted to sponsor Sawston and Babraham Cricket Club.

Liam gained his industry experience on Wolseley UK’s Graduate Management Scheme, working his way up to Regional Sales Director level with responsibility for a £60 million region.
In addition to leading the financial management of CPS, he also heads up the Pre-Contracts team and oversees our HR, pricing, procurement and strategic planning. Since taking leadership of the business in 2016, turnover has grown from £4 million to over £50 million. Liam secured "Business Person of the Year" at the Cambridge Live Business Awards 2020.
