Catalytic converter theft has changed over the years, but it hasn't disappeared. While some areas have seen big reductions since peak years, vans and other higher-clearance vehicles can still be targeted because thieves can access the underside quickly and remove the part with common tools.

This refreshed guide removes the old "one town, one model" framing and focuses on prevention steps that apply to van drivers across the UK.

Why catalytic converters are stolen

Police crime-prevention guidance highlights the key driver: catalytic converters contain valuable metals, and criminals can sell or process stolen units. Vans can be attractive targets because they sit higher off the ground, making access easier than many cars.

Prevention: the steps that actually reduce risk

1) Park to make access awkward

Police advice includes:

• Park in a locked garage or secure yard where possible.
• If on-street, park in well-lit, well-populated areas.
• Park close to a wall/fence/kerb so the exhaust side is harder to reach.
• Avoid parking half on the pavement/half on the road, which can make access easier.

2) Consider a guard/lock and mark the converter

Cambridgeshire Constabulary advises speaking to your dealer about locks/guards (including options tested to Sold Secure Gold), and many prevention guides recommend marking/forensic kits to make disposal harder. The RAC also notes that if you add security devices like guards/locks, you should declare them to your insurer and check whether it affects your policy.

3) Don't rely on "it only happens at night"

Some thefts happen overnight, but opportunist theft can happen in daylight too. Treat parking and security as an all-hours habit, especially on repeatable routes and regular stops.

If your catalytic converter is stolen: what to do

• Report it to police and obtain a crime reference number (often required by insurers).
• Document the damage with photos (cut pipes, wiring damage, underbody damage).
• Contact your insurer and check: excess, courtesy van/replacement vehicle, and whether any security upgrades should be added to the policy record.
• If you're a fleet or rely on the van for income, ask the repairer about lead times and whether parts availability will delay repair.

Key takeaways

• Converters can be removed quickly, so your best protection is deterrence + delay (parking strategy, guards, marking).
• The UK picture has improved in some areas since peak years, but risk remains for vans in particular.
• If you fit security devices, keep records and tell your insurer if required.
