Building a sustainable future, together
ESG in action through smart maintenance, environmental stewardship and community engagement
What ESG means to us
At Cambridge Maintenance Services Limited (CMSL), ESG isn’t a slogan: it’s how we work every day. The choices we make shape more than the buildings we maintain. They affect the people who use them, the communities around them, and the environment we all share.
That’s why sustainability, social value and governance aren’t side projects. They are built into every decision we make, from the engineers we hire to the partners we work with. For us, ESG means investing in our people so they can grow and thrive. It means using smart technology to cut energy waste and carbon. It also means giving back through volunteering and local partnerships. Most importantly, it means holding ourselves accountable through ISO standards, transparent reporting and a culture of responsibility. At its heart, CMSL delivers facilities management that keeps buildings performing at their best while creating a positive impact far beyond the site gates. That’s why ESG matters not only to us, but to every client and community we support.
That’s how we help our clients operate responsibly, efficiently and with complete confidence.
Environmental stewardship
We treat every building as part of the planet we share.
By integrating our smart building analytics platform, with in-house BMS expertise, we monitor energy use, temperature and air quality in real time. This insight lets our engineers act before small issues become big energy drains.
On one London campus, we uncovered 24/7 plant operation and lighting left on overnight. A simple schedule reprogramming reduced energy use by 18.3% and saved over 160 tonnes of CO₂ in a single year.
Beyond client sites, we are reducing our own footprint through our Local-for-Local model, which cuts travel miles and fleet emissions.
Social responsibility and community engagement
Real social value happens when you roll up your sleeves. We treat our team as individuals first and professionals second, because people matter beyond their roles. Our Local-for-Local model means we employ staff close to their sites, supporting local economies and ensuring faster response times.
We nurture future talent through apprenticeship programmes, and we give back through charity challenges, awareness days and volunteering. From sixty-mile cycle rides for bereavement charities to half-marathons for hospices, every event strengthens our teams and communities alike.
We are proud to support our people even beyond work. When an engineer joins the Dumball Rally, we back them, not because it is a company event, but because encouragement and personal growth are part of our culture.
Governance and ethical practice
Trust is earned through transparency and accountability
CMSL holds ISO 9001, ISO 14001 and ISO 45001 certifications, alongside accreditations including CHAS, SafeContractor, Gas Safe, F-Gas and NICEIC. These assure clients that every aspect of our delivery meets rigorous standards. Our governance framework covers modern slavery, anti-bribery, equality, diversity and data protection. All policies are available on our website and internal portal, ensuring clients, staff and partners can access the latest versions at any time. Our ESG performance is overseen by a dedicated ESG Coordinator who works with senior leadership to track progress, share best practice and report results across all regions.

What our clients say
CMSL couldn’t have handled it better. The Helpdesk and Out of Hours Helpdesk were quick to respond during a recent out of hours callout, and the reactive communication since has been clear, professional, and consistent.
“CMSL have been an outstanding partner to work with. The team are consistently professional, friendly, and highly skilled, which makes every project smooth and efficient. What stands out is the proactive approach. CMSL regularly bring forward practical suggestions around sustainability and cost savings, helping us future proof operations while staying budget conscious. Integrity, clear communication, and reliable delivery throughout.”
I can highly recommend Cambridge Maintenance Services from my experience working with them at 55 Bishopsgate. We had a three-man static team along with various subcontractors, and I also used their mobile services at Eldon House and 4 Moorgate.Their engineering advice is solid and reliable, and you can tell that the account managers have hands-on experience, which really supports the site teams. They are quick to respond to reactive issues and have never missed a KPI at my managed building.
Cambridge Maintenance Services also has a large pool of specialist subcontractors. They were able to select the right contractors to suit the tenant's needs, and they have excellent cover for annual leave and sickness. Paul Younan in particular has been helpful in identifying problem areas and offering solutions that provide real value, including advice on energy-saving devices.
“CMSL acted quickly and took full ownership of the issue from the outset. The team coordinated the right support, kept everything moving, and ensured the works were delivered smoothly with minimal disruption. A job well done, and I appreciate the professionalism throughout.”
We recently faced a challenging situation at our Torquay site, and CMSL delivered outstanding support. From the moment they became involved, the team took full ownership, coordinated the required works, and ensured everything ran smoothly on site. The issue was resolved efficiently, disruption was kept to a minimum, and communication throughout was clear and reassuring. Exactly what you want from a facilities partner when it counts.

“CMSL are always professional, responsive, and particularly helpful. The helpdesk support is brilliant.”
CMSL provide quick, proactive support that feels like an extension of our own team. Since the contract changeover we have had consistent communication, confident guidance during urgent incidents, and dependable cover when it mattered. The service is responsive, practical, and shows real care for the building and its occupiers. CMSL have built strong relationships on site and their reliability gives us peace of mind.
Since starting my new role at Crossgates in January, I’ve been hugely impressed with the support received from CMSL. Sarah Hodgson, in particular, has been an incredible help—always professional, approachable, and quick to provide the information and assistance I need when booking jobs. Her support has made a real difference for both myself and Ian at Crossgates. A huge thank you to Sarah and the CMSL team.
“CMSL couldn’t have handled it better. The Helpdesk and Out of Hours Helpdesk were quick to respond during a recent out of hours callout, and the reactive communication since has been clear, professional, and consistent.”
Your professionalism, attention to detail and dedication have been exemplary and don’t go unnoticed. Whenever we’ve called upon CMSL the service has been exceptional, with a real sense of care for the asset. It’s rare to see this level of service and commitment these days and we’re very grateful to be partnered with you and the company. Thank you for going above and beyond, it’s greatly appreciated.
Cambridge Maintenance have been with us for some time now and I’m very impressed with how professional and helpful both their engineers and Helpdesk team are. Mark Woolhouse, our site engineer, is one of the most professional, helpful, and nicest people I have ever worked with. He always ensures everyone is happy and follows up thoroughly on any issues. Mark is a great asset to the company. The Helpdesk Advisors are equally outstanding—always available, professional, and willing to help explain things further when needed. Melissa, in particular, has been brilliant, always happy to help and quick to resolve any concerns. I cannot thank the CMSL team enough.
CMSL went above and beyond to resolve an issue for us quickly. The engineer was patient, professional, and even sourced a replacement part on the spot rather than waiting for delivery, ensuring minimal disruption. We are very grateful for the effort and the outstanding service provided.
It’s always a pleasure working with Carla and Maisie. Their response to a recent sprinkler issue was quick, practical, and professional. The CMSL engineer on site also offered to help without hesitation, which really reflects the team’s supportive and proactive approach.
