Key Holding & Alarm Response

Citrus Security Services provides fast, effective alarm response and keyholding services using the latest mobile communications, onboard navigation and GPS to deliver a high quality and truly transparent service to our customers.

We have restricted our geographical coverage ensuring quicker alarm response times.  Crucially we do not overload our vehicles with a large customer base and we certainly do not use sub-contractors. Detailed reporting, effective communication combined with timely and accurate invoicing makes our key holding and alarm response service easy to use and an affordable solution to providing out of hours security.

How much does our key holding and alarm response service cost?

Every customer has bespoke requirements, so please contact us and arrange for one of our Key Holding and Response Managers to meet with you and gain a full understanding of your requirements. You can find out more from our Price List which is a rough idea on charges. However give us a call or fill out our online contact Quote form as prices Vary based on hours & contract type

I would recommend the services of  Citrus Security. We used their Security for our offices in Portsmouth, Southampton & Reading and they did an excellent job. Both the security guards were friendly and helpful. I'm happy to recommend the services of Citrus Security.”
