How to protect your Catalytic Converter from theft in Hertfordshire

There are ways to prevent the theft of your catalytic converter, mainly by making it harder to access and remove it. Below are a few suggestions on how to deter thieves or at least slow them down:

  • Parking closer to walls, other vehicles or close to the kerb, to make climbing under your car more difficult.
  • Marking the catalytic converter with an engraved serial number can allow easier tracing as well making it harder to sell
  • Welding the bolts if the converter is bolted on. This does not stop thieves but makes it harder to remove the converter using only a spanner. The downside to consider is that it not only makes it harder for thieves but also mechanics when they are working on your exhaust system.
  • Get a protective cover fitted to make it more difficult for thieves to remove the converter
  • Get a catalytic converter alarm which is set off when the catalytic converter is tampered with
  • Increased security measures, e.g. if possible park in a lockable garage, fencing, park in well-lit areas or CCTV ?

Why does catalytic converter theft happen in Hertfordshire?

Catalytic converters contain valuable and expensive metals, palladium and platinum, which makes them a target for theft. As the price for these metals increases the numbers of catalytic converter theft go up as well.
