  • I am very happy with the way the 4 visits were conducted, over the last couple of weeks. The entire process from requesting the visit to execution was very efficient, simple and professional. I thought of providing positive feedback. Well done to your team and thanks. Mr Gandhi, Wimbledon
  • We would like to express our sincere thanks and appreciation for the excellent service provided by CMS Keyholding and their team. We regretfully had a flood in our house and the team at CMS Keyholding immediately attempted to contact us, as well as make every effort to remedy the matter.

    While we were away and therefore had to travel back, they were extremely proactive and helpful in monitoring the house, arranged for overnight cover and ensured keys were available to nominated parties, so that the house could be cleaned. We would have no trouble in recommending CMS Keyholding to anyone and again thank them for their help in our time of need.

    Mrs Erdmann, Wandsworth

Both my London-based friends, who also came to our rescue, have expressed how professional your team was.

  • 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.
