Theft of catalytic converters in Milton Keynes

Alert message sent 12/11/2020 15:32:00

Information sent on behalf of Thames Valley Police

Thames Valley Police is urging owners of vans, 4 x 4’s, people carriers and other vehicles with a higher ground clearance to consider security following a spate of thefts of catalytic converters from the fitted exhaust systems of vehicles in Milton Keynes. Cars particularly targeted recently have been Honda Jazz, Toyota Prius and Auris. 

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 on the side where the exhaust is fitted.. 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 specialist protective cover or clamp to your vehicle to make life more difficult for an offender. Contact your vehicle dealership for options.

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 catalytic marking kit can be ordered from the following secure link: or by phoning 01233 333000.
