Introduction
One of the best-kept secrets in home security is that your alarm system often pays for itself through insurance discounts. Most homeowners don’t realize how significantly an alarm system can reduce their home insurance premiums. This guide explains how insurance discounts work, what qualifies, and how to maximize your savings.
At Garrison Alarms, we help homeowners understand the full financial picture—not just installation cost, but long-term value including insurance savings.

- DIY installation: Smaller discount or none
- Certified installer: Verification helps qualify
4. System Certification
- COC-certified installation: Qualifies for full discount
- Non-certified: Reduced discount or none

- Request the discount in writing
- Get confirmation of new premium
Documentation to provide:

FAQ: Insurance Discounts and Home Alarms
Will my alarm definitely get me an insurance discount?
Probably, but not guaranteed. Discount depends on system type, brand, installation quality, and your specific insurer. Contact your insurer to confirm before installing.
How much discount should I expect?
Typically 5–20% depending on system quality and monitoring. Average is 12–15% for mid-range systems with monitoring.
Does monitoring have to be with an approved center?
Yes, most insurers require monitoring through professional central station. DIY app monitoring usually doesn’t qualify for discount.
What if my alarm system is more than 5 years old?
You can still get discount, but it may be reduced for older systems. Some insurers require system update after certain age.
Can I get discount for partially installed system?
Possibly, but discount will be reduced. Full perimeter coverage gets maximum discount.
Do I have to keep paying for monitoring to keep the discount?
Check with your insurer. Most require ongoing monitoring to maintain discount. If you cancel monitoring, discount may be removed.
What if I install alarm system myself?
You may get a smaller discount or none at all. Professional installation typically required for full discount.
Does professional installation cost affect insurance discount?
No, discount is based on system itself. But professional installation is usually required to get discount.
What happens if my alarm fails and I'm robbed?
If system was operational and monitoring active, insurer has confidence in your preparedness. Non-functional system may limit recovery.
Can I transfer discount if I move homes?
Possibly, if new home is similar and you reinstall system. Contact insurer to confirm.
Does renter's insurance offer alarm discounts?
Renter’s insurance focuses on contents. Alarm discount usually not available for renters, as property owner maintains security.
