Frequently Asked Questions
What does a keyholding and alarm response service include?
Keyholding includes securely storing a set of your keys and responding to any alarm activations on your behalf. When an alarm goes off, our officers attend the site, carry out a full inspection, deal with any issues and secure the property before leaving. You receive a detailed incident report after every call-out.
How fast can ALG Security respond to an alarm?
Our team operates 24 hours a day and responds as soon as an alarm notification is received. Because we cover North Wales with local officers, response times are fast and consistent.
Is keyholding safer than sending my staff to investigate alarms?
Yes. Alarm call-outs often happen at night and can involve unknown risks. Using trained SIA licensed officers removes the danger from your employees and ensures that every response is handled safely and professionally.
Will I be updated after every alarm call-out?
Absolutely. Transparency is a key part of our service. After each attendance you receive a full incident report explaining what happened, what was found and if any further action is recommended.
Can this service support multiple buildings or sites?
