When choosing an alarm system there are 4 different alarm grades to consider

Thatcham Recognised Installer

Thatcham Category 1 (Cat 1)

Rated as the highest in its class. The Thatcham Category 1 alarm/immobiliser system as standard comprises of:


  • Alarm Perimeter detection (Doors, boot & bonnet)
  • Ignition detection
  • Passenger compartment movement detection (Interior sensors)
  • Inclination detection (Motorcycle only)
  • Battery back-up power supply (Siren)


  • Dual circuit immobiliser (x2 points of isolation)
  • Passively armed

This particular system is mainly suited to high performance/sports cars or for vehicles without any security fitted as standard. On certain vehicles, your insurance company may require this type of system to be fitted as a minimum. It also allows for maximum insurance discount.

Thatcham Recognised Installer

Thatcham Category 2-1 upgrade

Utilising the original equipment/manufacturers (OE) immobiliser, this insurance approved alarm will upgrade the security level of your vehicle from a Thatcham Category 2, to a Thatcham Category 1 alarm.

It consists of all the features the Thatcham Category 1 system has, minus the immobiliser circuits, as they would already be fitted on your car as standard.

This type of system is only suited for vehicles produced after the year 2002. The majority of UK registered cars from 2002 onwards were factory fitted with an immobiliser system as standard; please call for vehicle compatibility.

Thatcham Recognised Installer

CAN bus Thatcham Category 2-1 upgrade

The Thatcham CAN bus category 2-1 upgrade alarm is designed for cars using full CAN Bus or semi CAN Bus systems. (Normally found in cars manufactured after 2003).

This system is designed to be used with the vehicles original remote controls, however, if your vehicle has only one remote control supplied as standard, we can add an additional remote to the system (if required). This will prove more cost effective than buying an original remote control from the dealer if another backup key fob is required.

We highly recommend this system for certain vehicles as the alarm is designed and programed to work exactly with the cars original wiring and databus network. The overall outcome gives the user an original equipment installation and a reliable, robust security solution.

Please call to see if your vehicle is CAN bus compatible.

Non-Thatcham system

These systems work great for your basic needs. Depending on what you require, they can be easily customised by either adding or taking away various options and sensors.

If you needed a system to remotely control your central locking and cover the perimeter of your vehicle, but didn’t require an immobiliser or interior sensors this system can be tailored to your exact specifications.

Please note: A non-Thatcham approved system will not qualify for any reductions in insurance premiums.
