Owners of vans, 4x4s, people carriers and other vehicles with a high ground clearance to consider security following a spate of catalytic converter thefts from the fitted exhaust systems of vehicles in Milton Keynes.

The following advice is provided for all vehicle owners to help safeguard their catalytic converters;

Defensive Parking – Where possible park in your garage. If not try to park next to a high curb or other area that restricts access underneath your vehicle. If possible park in a well lit area or consider security lighting;

CCTV – Consider installing a CCTV system to cover your vehicle as a deterrent;

Welded Bolts - If your catalytic converter is a “bolt on” it is possible to have the bolts welded shut;

Catalytic Converter Protective Sleeves/clamps – Consider fitting a protective cover or clamp to your vehicle to make life more difficult for an offender;

Alarm System – Consider fitting a specific catalytic converter alarm to warn of any tamper attempts. Some alarms can send a text message to your phone and activate a siren and flashing lights. If possible choose a Thatcham approved product;

Identify/etch your converter - Consider permanently marking your catalytic converter to make it less desirable for criminals to steal and sell on. The Retainagroup offer a kit consisting of a virtually indestructible sticker, metal marking fluid and a window sticker (to warn thieves that the catalytic converter carries an identification mark). Each mark contains a seven digit code and a 24 hour telephone number for the International Security Register who store the code against vehicle details. A catalyst marking kit can be ordered from the following secure link: or by phoning 01233 333000.
