A Thatcham S5 tracker is a vehicle security system certified to meet the highest tracking standard set by Thatcham Research. It is designed to help locate and recover a vehicle in the event of theft and is commonly required by insurers for high-value or high-risk vehicles. Certification confirms that the system meets strict performance, reliability, and monitoring criteria.

Thatcham S5 trackers include driver identification technology, meaning the system can recognise whether an authorised driver is present when the vehicle is used. If the vehicle is driven without the correct identification, the monitoring centre is alerted. This added layer of verification provides enhanced protection against key theft, relay theft, and unauthorised use.

Yes. Thatcham S5 trackers must be connected to a secure, 24/7 monitoring centre to maintain certification. This service allows trained operators to verify thefts, track the vehicle in real time, and liaise with police where required. An active subscription is essential for both insurance compliance and effective vehicle recovery.

A Thatcham S7 tracker is a vehicle tracking system that satisfies the S7 category standard established by Thatcham Research for stolen-vehicle location devices. S7 devices are designed to monitor the position of a vehicle and support recovery efforts if it’s taken without permission, helping insurers and recovery services locate the vehicle efficiently.

An S7 tracker continuously monitors where your vehicle is and sends data to a secure control centre. If the vehicle is moved without authorisation, the system generates an alert and enables real-time tracking, assisting recovery teams and police in locating the vehicle. Most S7 systems also detect motion or tow attempts and often include battery backup so the tracker continues working even if the main power is cut.

Yes. To meet Thatcham certification requirements, S7 trackers must be connected to a 24/7 monitored service that oversees alerts and coordinates with recovery authorities. These devices also require fitting by a qualified installer to ensure they function reliably and comply with insurer conditions.

A Thatcham Category 2 immobiliser is an engine immobilisation system approved under Thatcham Research security standards. Its primary purpose is to prevent a vehicle from being started without the correct, authorised key or electronic authentication. Category 2 focuses solely on immobilisation rather than audible alarms or tracking functions.

A Cat 2 immobiliser automatically activates when the vehicle is switched off. It disables one or more essential engine systems so the vehicle cannot be driven unless the correct coded key or transponder is present. This prevents common theft methods such as hot-wiring or forced ignition starts, making unauthorised use significantly more difficult.

Insurers recognise Thatcham Cat 2 immobilisers because they are independently tested and certified to meet defined security performance standards. Approval confirms the system is reliable, tamper-resistant, and effective at preventing unauthorised engine start. As a result, many insurers accept Cat 2 immobilisers as an approved theft-prevention measure.
