Commercial insurance policies frequently include specific requirements for intruder alarm systems. For Bristol businesses, understanding these requirements is essential to ensure your policy remains valid and claims are not rejected on technical grounds.
Typical Insurance Requirements
- System grade: Insurers specify a minimum system grade under BS EN 50131 (typically Grade 2 or Grade 3)
- Installation standard: Systems must be installed by a British Standards-compliant contractor
- Maintenance: Annual professional maintenance as a minimum, documented with service records
- Monitoring: Higher-risk premises may require connection to an ARC
- Setting discipline: The system must be fully set whenever the premises are unoccupied
What Happens If You Do Not Comply?
If your intruder alarm does not meet the standard specified in your policy, or if maintenance is not carried out as required, your insurer may:
- Refuse to pay a claim related to break-in or theft
- Increase your premium at renewal
- Add additional conditions or exclusions to your policy
- Cancel your policy entirely in serious cases
