Catalytic converter theft - what to look out for

Catalytic converter theft - what to look out for

Dear Resident,

If you own a vehicle, it will likely have a catalytic converter – a part fitted to the exhaust system that reduces harmful emissions.

Unfortunately, these devices are often targeted by thieves because they contain valuable metals. Criminals can remove a catalytic converter in under a minute, often using basic tools and working in pairs.

While thefts have reduced significantly in recent years due to police action and prevention measures, offences still occur and residents are encouraged to remain vigilant.

⚠️ Where and how thefts happen

Most commonly in car parks and residential streets, but can occur anywhere

Offenders may:

Jack up vehicles
Use cutting tools underneath cars
Work in daylight, sometimes posing as tradespeople

Stolen converters are often sold quickly via scrap networks or online markets

Hybrid vehicles are more frequently targeted due to the higher value of materials, but any vehicle can be at risk.

There are simple steps you can take to reduce your risk:

✅ Protect your vehicle

Fit a catalytic converter lock or guard (look for Sold Secure Gold or police‑approved products)

Consider security marking or registering your converter to make it harder to sell

Ask a garage about etching your VIN or installing protective devices

✅ Park smart

Use a garage or secure compound where possible

Otherwise, park in a well-lit, busy area overlooked by others

Position your car to limit access underneath (e.g. close to a wall or another vehicle)

Be aware that SUVs, vans and vehicles with higher clearance are more vulnerable

✅ Stay alert

Look out for:

Vehicles being lifted with a jack
People working underneath cars
Loud cutting or drilling noises

It’s also worth noting that vehicle crime trends are changing, with some offenders shifting to other items such as EV charging cables—so general vehicle security remains important.

📞 Reporting Suspicious Activity

If a crime is in progress: call 999
(If you are unsure, please still call – officers can assess the situation)

If safe to do so:

Take note of descriptions, vehicles, or registration numbers
Do not approach suspects

If the crime has already happened:

Report online or via 101

We hope this information helps you keep your vehicle safe.

Kind regards,
