Keyholding & Alarm Response Services

24/7 response and peace of mind

When an alarm is triggered, you need to know someone will respond quickly, safely, and professionally. At Central Southern Security, we provide keyholding and alarm response services that protect your property around the clock. Our trained engineers respond to activations day or night, ensuring issues are dealt with promptly and your site is secured again before you return.

Serving homes, schools, councils, and businesses across Hampshire, Dorset, and surrounding areas.

What is keyholding?

Keyholding means we securely hold a set of your property keys and act as your first responder if an alarm is activated or a fault occurs. This keeps you and your staff safe while ensuring every incident is handled by a qualified professional.

Benefits

• 24/7 availability, 365 days a year

• Rapid response to alarm activations

• Reduced risk to staff or property owners

• Detailed incident reports and system checks

• Optional follow-up maintenance and servicing

Professional alarm response

When an alarm is triggered, our on-call engineer is dispatched immediately. They attend the site, investigate the cause, and take the necessary action — whether that means resetting the system, contacting the police, or securing the premises.

Our vehicles are equipped for access and communication with our control centre, allowing instant updates and coordination.

Each response is logged and reported for your records, providing full transparency and traceability.

System maintenance and ongoing care

Many of our keyholding clients also choose to include ongoing maintenance and servicing for their alarm systems. This ensures your system continues to perform reliably and minimises false activations.

Our maintenance service includes:

• Scheduled servicing and inspections

• System testing and recalibration

• Replacement of worn sensors and batteries

• Firmware updates and diagnostics

• 24/7 out-of-hours call-out for contract customers

Regular maintenance keeps your system insurance-compliant and extends its lifespan.
