Customer Testimonials

Superb service and great value for money. Thanks to Paul and Lukas for getting us out of trouble yesterday (not for the first time). CMS are a fantastic and well-priced insurance. I can’t recommend them too highly


As usual, I can only praise CMS Keyholding for their professional service. The Key Guard’s name was Paul Williamson on the night that I had my key fobs stolen from my car and he was there, at my premises, before I arrived which was most reassuring and quite amazing. He was calm and efficient and I can only praise and thank you for having such professional employees. Yours faithfully.


I would like to pass on my thanks and appreciation for the excellent service your staff provided. I have been in the security industry for over 30 years and have to say it has been a long time since I have used a security service provider who has excelled so much on the first occasion. Both the operators on the ground and your call centre and office staff were outstanding.
