Why Regular Fire and Security Maintenance Matters

Fire and security system maintenance is essential to ensure that all safety and protection measures remain reliable, compliant, and fully operational. A consistent maintenance schedule not only extends the lifespan of the systems but also provides peace of mind that your premises, assets, and personnel are continuously protected.

Routine inspections help identify early signs of wear, sensor misalignment, software faults, battery failures, and other issues that can compromise protection. By maintaining your system to industry standards, you reduce risk, avoid costly downtime, and ensure compliance with British regulations and insurer requirements.

A Proactive, Preventative Approach

We focus on preventing problems before they develop. During maintenance visits, we conduct systematic checks, test performance under realistic conditions, and identify early signs of wear or failure. This approach helps you avoid avoidable breakdowns, unnecessary costs, and compliance issues.

Fully Trained, Up-to-Date Engineers

All AEL engineers are trained to the latest British Standards and technologies across fire detection, CCTV, access control, intruder systems and monitoring platforms. You benefit from correct testing procedures, accurate fault diagnosis and compliant reporting.

Fire Alarms

Fire alarm maintenance ensures your system stays fully operational and compliant with UK fire safety regulations. Regular servicing checks detectors, sounders, call points, control panels and signalling paths to confirm they respond correctly and to identify faults early. This reduces false alarms, supports compliance with BS 5839 and insurer requirements, and ensures the system will perform reliably in an emergency.

Emergency lights

Emergency lighting maintenance ensures all units operate correctly during a power failure or emergency. Routine servicing checks luminaires, backup batteries, control gear and automatic activation to confirm the system performs as required. Regular testing verifies compliance with BS 5266 and supports safe evacuation by keeping escape routes illuminated and equipment in reliable working condition.

CCTV

Regular CCTV maintenance is essential to ensure clear image quality, reliable recording, and full system performance. Over time, cameras can drift out of focus, lenses can become obscured, hard drives can fail, and network or power issues can interrupt live or recorded footage. Routine servicing identifies these faults early, verifies that all cameras, NVRs, storage and remote-access functions are working correctly, and reduces the risk of missing critical footage. A well-maintained system minimises downtime, extends equipment lifespan, and provides dependable protection for your premises.

Access Control

Access control maintenance ensures that door controllers, readers, locks and software continue to operate securely and without interruption. Issues such as worn locks, failing power supplies, unresponsive readers or outdated permissions can lead to access failures or security risks. Routine servicing identifies these faults early, confirms that credentials work as intended, and keeps the system aligned with your security policies. Proactive maintenance minimises downtime, protects assets, and ensures authorised personnel can access the premises smoothly and reliably.

Intruder Alarms

Intruder alarm maintenance is essential to ensure the system remains reliable and provides effective protection against unauthorised access. Over time, issues such as faulty sensors, ageing batteries, damaged wiring or connection problems can lead to false alarms or delayed activation. Regular servicing checks that all detection devices, control equipment and signalling paths respond correctly, and identifies faults before they cause system failure. Maintenance also ensures the system remains compliant with relevant standards and that any changes to the building layout or usage are reflected in the alarm’s configuration, keeping your premises fully protected.

Accreditations

We’re committed to delivering the highest standards across every project. Our fire safety services are BAFE certified, and our security solutions are approved to NSI Gold standards — the industry benchmark for excellence. We also hold Constructionline, CHAS, SafeContractor, and ISO 9001 certifications, ensuring all work is carried out safely, professionally, and in full compliance with audited industry standards.
