Thatcham security

There are different categories of Thatcham security devices ranging from combined Alarms and Immobilisers through to After Theft Tracking Systems and Q Class non categorised aftermarket devices. In each category, third party security products have been evaluated using specific tests to indicate the effectiveness of the product. Each Thatcham security product is subject to a review after 12 months so you may find that some out of date systems are delisted.
