What Is TASSA?
TASSA – the Tracker and Aftermarket Security System Association – is an independent UK body that tests and approves vehicle security products. Since 2019 insurers have leaned on TASSA listings to decide which devices merit premium discounts.
Why Does Certification Matter?
- Verified effectiveness: Devices must withstand penetration testing, RF attacks and CAN spoofing.
- Fitters vetted: Installers need DBS checks and comply with codes of practice.
- Insurer trust: Many UK insurers now require TASSA approval for theft‑cover on keyless cars.
CarGuard CAN Immobiliser & TASSA
The CarGuard CAN Immobiliser passed TASSA’s 25‑point attack simulation, making it one of the few devices that blocks relay attack and OBD plug‑in hacks.
How to Check a Product or Installer
- Visit the official TASSA database.
- Enter the product ID or installer number.
- Verify status is “Current” and “Certified”.
Insurance Benefits
Submitting your TASSA certificate can reduce premiums by up to 15 %. Always notify your insurer post‑install to ensure theft cover remains valid.

What is TASSA certification for car security? +
TASSA — the Tracker and Aftermarket Security System Association — is an independent UK body that independently tests and approves aftermarket vehicle security products. A TASSA certification confirms that a device meets rigorous anti-theft performance standards. Since 2019, major UK insurers have used the TASSA product list to decide which devices qualify for insurance premium discounts.
Does TASSA certification reduce my car insurance? +
Yes, in many cases. Most major UK insurers recognise TASSA-approved devices and offer premium reductions for vehicles fitted with certified security products. The discount varies by insurer and vehicle, but some policyholders report savings of £100 or more per year — often recovering the installation cost within the first year.
How do I know if a car security product is TASSA approved? +
You can check the official TASSA website at tassa.org.uk for their approved product list. When TuneCar installs a CarGuard CAN immobiliser, we issue an official TASSA certificate that you can provide directly to your insurer as proof of approved installation.
Is TASSA the same as Thatcham approval for car security? +
No, TASSA and Thatcham Research are different organisations. Thatcham focuses primarily on tracking devices, while TASSA covers a broader range of aftermarket security systems including CAN immobilisers. Both are recognised by UK insurers, and some products carry both approvals.
