What our clients say
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.
“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.”
“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.”
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.
“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.”
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.
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 are always professional, responsive, and particularly helpful. The helpdesk support is brilliant.”
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.
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.
