Thatcham Approved Alarms and Immobilisers
Whether you’re protecting a high-value vehicle or simply looking to enhance your car’s security, Thatcham-approved alarms and immobilisers provide industry-leading protection against theft, giving you peace of mind and potentially helping to lower your insurance premiums.
What is Thatcham Category 1?
Thatcham Category 1 (CAT 1) is the highest classification for car alarm and immobiliser systems, designed to provide maximum security against theft and unauthorised access. Installing a CAT 1 system offers top-tier protection, which can be a key factor in preventing theft and aiding recovery efforts.
Key Features of Thatcham Category 1 Systems
Dual-Circuit Immobiliser
Automatically prevents the engine from starting unless the correct key or fob is used.
Perimeter Alarm
Detects if doors, bonnet, or boot are opened without authorisation, offering comprehensive vehicle monitoring.
Interior Movement Sensors
Uses ultrasonic or microwave sensors to detect movement inside the car, detecting intrusions.
Battery Backup Siren
The alarm has a separate power source, so it still works if the main battery is disconnected, ensuring uninterrupted protection.
Tamper Detection
Triggers an alert if someone attempts to disable the system, offering an added layer of defence against thieves.
Who Needs a Category 1 System?
- Often required by insurers for high-value or high-risk vehicles.
- Beneficial for those looking to enhance their car’s security beyond factory-fitted systems.
By choosing a CAT 1 system, you’ll benefit from improved theft deterrence and enhanced vehicle protection, which can also result in lower insurance premiums.
If you’re considering a Thatcham CAT 1 system, make sure it is professionally installed by an approved technician for full compliance and maximum security.
What is Thatcham Category 2?
Thatcham Category 2 (CAT 2) is a classification for electronic immobilisers designed to prevent vehicle theft by stopping the engine from starting without the correct key or fob. Unlike Category 1, CAT 2 systems do not include an alarm—only an immobiliser. Installing a CAT 2 system offers effective security, providing reliable theft prevention.
Key Features of Thatcham Category 2 Systems
Electronic Immobiliser
Prevents the engine from starting unless the correct key or transponder is present.
Dual-Circuit Immobilisation
Disables two critical systems (e.g., ignition and fuel supply) to make hot-wiring impossible, offering robust protection.
Passive Activation
Engages automatically when the key is removed, without requiring driver input, for convenient and automatic security.
Unique Key or Fob Required
Only an authorised key or fob can deactivate the immobiliser, providing an additional safeguard against theft.
Who Needs a Category 2 System?
- Many modern cars already have a factory-fitted CAT 2 immobiliser as standard.
- If your vehicle lacks a built-in immobiliser, installing a Thatcham-approved CAT 2 system can improve security and may reduce insurance costs.
- Some insurers require a Category 2 to 1 upgrade (adding an approved alarm to an existing CAT 2 immobiliser) for better protection.
A CAT 2 system offers affordable yet reliable security, giving you the peace of mind that your vehicle is protected.
If you’re unsure whether your car has a CAT 2 system, check the owner’s manual or consult a Thatcham-approved installer.
