Catalytic Converter Thefts – A Message from Your PCSO

A Message from Les Conopo – Police Community Support Officer, Daventry and South Northants:

Preventing catalytic converter theft

Catalytic converters are designed to remove toxins from vehicle emissions and contain small amounts of three precious metals: platinum, palladium and rhodium. The value of these metals means the theft of a catalytic converter can provide a substantial return to a thief.

If your catalytic converter is stolen, you’ll know about it because your vehicle will sound different.  Transit/Sprinter vans and other high clearance vehicles are especially vulnerable, but there are steps you can take to help prevent this crime.

Advice for motorists:
Where possible, park your vehicle in a locked garage, as close to your home as possible or in a parking spot overlooked by residents
Consider installing a Thatcham approved alarm to your vehicle. Ones that activate if the vehicle is lifted or tilted are particularly effective.

Consider using a catalytic converter protection device or marking system approved by For further advice email

If you see someone acting suspiciously under a vehicle, report it to police. Obtain as much information as possible, including any vehicle registrations

Advice for businesses:
Employ defensive parking to ensure vehicles that are most vulnerable to theft are parked where they are least accessible to thieves. Consider blocking high clearance vehicles in with low clearance ones to prevent a would-be thief from getting underneath

Check your perimeter security. Ensuring your business has an appropriate boundary fence will act as a deterrent to opportunist catalytic converter thieves

Use lighting to illuminate areas where an intruder may be seen or attempt to operate
Consider investing in monitored CCTV to provide protection for your vehicle fleet

Check vehicle protection measures you are considering are approved by the Association of Chief Police Officers’ Secured by Design scheme:
If your catalytic converter is stolen, contact police immediately by calling 101.
