Cost-effective 24/7 response

Open 24 hoursWe are SIA licensed and accredited to provide rapid and effective key holding and security response services throughout the UK. Our cost-efficient remote monitoring gives you the peace of mind that we are protecting your site out-of-hours. If an alarm activates, we dispatch qualified and vetted security personnel to investigate all security alerts.

Your keys are carefully coded, sealed and secured within our office key safes nationwide and only released under tight controls if rapid activation is required to respond to an alarm activation, incident or emergency entry needs.

How our key holding and alarm response services work

  • In the event of alarm activation our 24/7 control centre will quickly dispatch a uniformed officer to site with your keys.
  • If it safe, our officer will enter your property and conduct a thorough security patrol to assess the situation.
  • If all is well we reset the alarm and lock up but if there are signs of damage or intrusion we contact the emergency services (if required) and ensure the premises are protected until re-secured.
  • Any issues are reported back to our control centre in real time and we provide you with a detailed incident response report.

Added value

Our keyholding and alarm response service is available across the UK and can be delivered as a stand-alone service or in conjunction with our mobile security patrols.

As keyholders we can also offer the following services:

  • Accompanied visits – we can meet your staff at unmanned sites and accompany them to reduce risk.
  • Vacant Property inspections
  • Building lock & unlock services – letting in cleaners or contractors.
  • Environmental patrols – switching off lights and power
  • Health & safety checks
  • Lone worker welfare visits
