Ways to keep your cat converter safe

Bromley has seen an increase in catalytic converter thefts over the past couple of months. Although Hayes and Coney Hall have only had a few reported it is well worth remembering some of the crime prevention advice around this; especially as there are lots of videos floating around on the intranet showing people how easy it is to steal them.

Cars which are often targeted are those with higher chassis, such as a 4×4 or an SUV, however, other cars can still be targeted.

To reduce the risk of having your catalytic converter stolen, you should:

  • Park your car in a locked garage where possible, but if this isn’t an option, then park it in a well-lit and well-populated area
  • Park close to fences, walls or a kerb with the exhaust being closest to the fence, wall or kerb to make the theft more difficult
  • Avoid parking your vehicle half on the pavement and half on the road, as this may make it easier for thieves to access the catalytic converter
  • If parking in a public car park, consider parking alongside other cars and facing you bonnet towards the wall if possible. With the catalytic converter positioned at the front of your vehicle, this will make it harder for thieves to get close enough to steal it
  • If there is a fleet of vehicles, park the low clearance vehicles to block the high clearance vehicles. This will obstruct access underneath
  • If your catalytic converter is bolted on, you can ask for your local garage to weld the bolts to make it more difficult to remove.
  • Alternatively, you can also etch a serial number on the converter
  • You can even purchase a ‘cage clamp’ which is a cage device that locks in around the converter to make it more difficult to remove
  • Speak to your dealership about the possibility of adding a tilt sensor that will activate the alarm should any thief try to jack the vehicle up to steal the converter
  • If you see someone acting suspiciously under a vehicle, report it immediately. Obtain as much information as possible, including any vehicle registrations.

Catalytic Converter theft has risen due to the value of what they are made of and how easy it is to steal them. A CAT can be bolt cut from the underside of a vehicle with relative ease, and they are lacking in identifying marks, which makes them hard to trace when they are resold.

A catalytic converter contains palladium, platinum, and rhodium – all precious metals.. If and when the prices of these precious metals rise, so does the value of a CAT, making them far more attractive to thieves.

Despite it being illegal to pay for scrap metal with cash, unfortunately, some merchants will buy stolen materials for cash, making it harder to trace the theft and tempting thieves to steal valuable car parts.

If you see someone acting suspiciously around a car please call 999 immediately. Although our vehicle crime rate remains low at the moment, neighbouring wards are being hit and we want to avoid giving these people golden opportunities.

Thank you for your help and support during this time,

Keep safe,
