Security System Maintenance & Repairs
Professional servicing that stops problems before they start. Regular maintenance prevents the expensive repairs that come when systems break down.
CCTV Maintenance
Keep cameras clean, storage working, and footage clear. We check angles haven't shifted, clean lenses, test recordings, and update software. Proper maintenance means clear footage when you need it.
Intruder Alarm Maintenance
Prevent false alarms and ensure real threats trigger response. Checks, testing, and updates keep your alarm protecting, 24/7. Our servicing slashes false alarms to one every six years - the industry average is one every year.
Access Control Maintenance
Keep doors working, cards active, and audit trails complete. Regular checks prevent Monday morning lockouts or emergency exits that don't open. We test all readers, update access lists, and ensure records are complete.

FAQs
Stay informed about security regulations, new tech, and best practices.
What does security system maintenance include?
Why is regular maintenance important for security systems?
How often should my security system be serviced?
Typically every 6 or 12 months, depending on system type, usage, and police or insurer requirements. High-risk or monitored systems may require more frequent visits.
Will maintenance reduce false alarms?
What happens if a fault is found during a service visit?
Are replacement parts included in the maintenance contract?
Will maintenance cause disruption to my business or home?
Disruption is minimal. Most checks are non-intrusive and planned in advance, with systems returned to full operation before the engineer leaves.
Is maintenance required to keep police response?
Yes. Police response typically requires an active maintenance agreement and compliant servicing to keep your URN valid.
Can you maintain system you didn't originally install?
Yes. Existing systems can be adopted following an initial assessment to confirm condition, compliance, and compatibility.
What are the benefits of a maintenance contract versus ad-hoc callouts?
Priority response, predictable costs, ongoing compliance, fewer faults, and better system reliability, without the delays and higher costs of reactive call-outs.
