Does a Security System Lower Your Home Insurance?
If you're comparing your options, see our alarm system installation in Sydney for a free site assessment and fixed-price quote.
Short answer: yes — a monitored alarm can reduce your contents insurance premium by 5–25%, depending on your insurer and system type. NRMA, RAC, Suncorp, and AAMI all offer documented discounts for professionally installed and monitored security systems. Here’s exactly how much you can save, which systems qualify, and whether the monitoring subscription pays for itself through the discount.

How Much Can a Security System Actually Save on Insurance?
| Insurer | Discount | What qualifies |
|---|---|---|
| NRMA Insurance | Up to 25% off purchase/install | Bosch or Uniarch systems via NRMA partner |
| RAC (WA) | Up to 25% off contents | RAC-monitored alarm system |
| Suncorp / AAMI / GIO | 5–20% off contents | Professionally installed alarm with monitoring |
| Allianz | Varies by policy | Monitored alarm + deadlocks noted on policy |
| Budget Direct | Up to 10% | Alarm system disclosed at quote time |
Discounts are on contents insurance premiums (not building cover in most cases). Exact discounts depend on your suburb, claims history, and system type. Always confirm with your specific insurer before purchasing a system based on insurance savings alone.
Which Systems Do Insurers Actually Recognise?
Not all security systems qualify equally. Insurers distinguish between three tiers:
- Monitored alarm with 24/7 back-to-base (Grade A1): The highest-value tier for insurers. A human at a certified monitoring centre responds when the alarm triggers — typically within 60 seconds. This is what earns the full 15–25% discount from NRMA and RAC.
- Self-monitored alarm (app-only): The alarm pushes a notification to your phone but there's no professional monitoring centre. Most insurers give a smaller discount (5–10%) or none at all — because there's no guaranteed response.
- CCTV only (no alarm): CCTV alone rarely qualifies for a meaningful insurance discount. Cameras provide evidence after an incident but don't deter or trigger a response during one. Some insurers give a token 2–5% for professionally installed CCTV.
The highest insurance value comes from monitored alarm + CCTV combined. The alarm triggers the response; the CCTV provides evidence for the claim. If you're buying a system partly for insurance savings, start with the alarm + monitoring and add cameras second.

- Average home contents premium in NSW: approximately $700–$1,200/year
- 15% discount for monitored alarm: saves $105–$180/year
- Professional monitoring subscription: $30–$60/month = $360–$720/year
- Net cost of monitoring after insurance offset: $180–$540/year
So monitoring doesn't fully pay for itself through insurance alone — but it significantly reduces the net cost. And the real value of monitoring isn't the insurance discount; it's the 24/7 professional response that the discount reflects. The insurer gives you a discount because monitored homes have fewer and smaller claims — the system actually works.
If you're on a tight budget: get the alarm installed, skip monitoring for now, and add it later. Even a self-monitored alarm with the system declared to your insurer will earn a 5–10% discount.
What Documentation Do Insurers Ask For?
When you update your insurance policy to declare your security system, most Australian insurers ask for:
- Type of system (alarm only, CCTV only, or combined)
- Whether it's professionally installed (DIY systems may not qualify for full discount)
- Whether it's monitored (and by whom — Grade A1 monitoring centres carry more weight)
- Installation certificate or invoice (some insurers request this; most accept a verbal declaration at quote time)
Keep your installation invoice and monitoring contract accessible — you'll need them if you make a claim and the insurer verifies your declared security arrangements.
Frequently Asked Questions
Does a security system lower home insurance in Australia?
Yes. Monitored alarm systems can reduce contents insurance premiums by 5–25% depending on your insurer. NRMA offers up to 25% for Bosch/Uniarch systems. RAC offers 25% for monitored alarms. Suncorp/AAMI/GIO offer 5–20%. CCTV alone rarely qualifies for a significant discount.
Does a self-monitored alarm get an insurance discount?
Some insurers give a smaller discount (5–10%) for self-monitored systems that push app notifications. But the full 15–25% discount typically requires professional 24/7 back-to-base monitoring from a Grade A1 centre. The insurer values the guaranteed response, not just the detection.
Do I need professional installation for the insurance discount?
Most insurers require or prefer professional installation for the discount to apply. DIY-installed systems (Ring, Eufy, Arlo) may qualify for a token discount but typically not the full monitored-alarm discount. Check with your specific insurer before installing.
Does CCTV lower home insurance?
Minimally. CCTV alone provides evidence after an incident but doesn't deter or trigger a response during one. Most insurers give 0–5% for CCTV only. The combination of monitored alarm + CCTV gets the highest discount because it covers both response and evidence.
How much does home alarm monitoring cost per month?
$30–$60/month for residential 24/7 back-to-base monitoring from a Grade A1 centre in Australia. Annual cost: $360–$720. After the insurance discount offset (typically $105–$180/year), the net monitoring cost drops to $180–$540/year.
Will my insurer check if my security system is actually working?
Not routinely — but if you make a claim, the insurer may verify your declared security arrangements. If you claimed a discount for a monitored alarm and the system was disconnected or not functioning at the time of the incident, the claim could be reduced or denied.
