Catalytic Converter Theft – Risks and 8 Prevention Tips
Catalytic converter theft is rising fast across the UK, and your car could be next. This crime happens in minutes and leaves you with a huge repair bill. It’s silent, costly, and frustratingly common.
Hybrid cars, SUVs, and vans are prime targets. Thieves know exactly where the catalytic converter is and how to remove it. With precious metals inside, a stolen converter can fetch hundreds.
So, how do you stop it? In this guide, we’ll explain why theft happens, which vehicles are at risk, and most importantly, how to protect yours with simple, proven steps.
What Is Catalytic Converter Theft and Why Is It on the Rise?
Catalytic converter theft is when someone steals the exhaust part from under your car. It contains precious metals like platinum, palladium, and rhodium, which sell for high prices. On average, a catalytic converter costs between £150 and £900 to replace. For some luxury cars or high-performance vehicles, the cost can exceed £1,000.
However, thieves can remove it in under two minutes, often while your car is parked. This leaves you with costly repairs and no warning until it’s too late.
Thefts in the UK surged between 2019 and 2022, with nearly 100,000 cases reported. In 2022 alone, there were around 75 thefts each day. High metal prices and low detection rates made it worse.
Which Vehicles Are Most at Risk of Catalytic Converter Theft?
Hybrid cars are the top target. That’s because their converters contain more precious metals. Since the engine runs cleaner, the metal inside corrodes less and stays more valuable.
Also, SUVs and vans are high-risk. They have more ground clearance, which makes it easier for thieves to get underneath quickly. Popular models like the Toyota Prius, Honda Jazz, and Lexus RX have been repeatedly targeted across the UK.
According to police data, older hybrid models face the most risk. Newer vehicles may have protected or differently designed systems, but they’re not immune. Even petrol cars are stolen if metal prices spike.
How Do Thieves Steal Catalytic Converters?
Thieves usually work in pairs and strike in daylight or at night. One person keeps watch while the other slides under the car. They use battery-powered tools to cut through the exhaust system. In most cases, the job takes less than two minutes.
High-clearance vehicles like SUVs make access easier. Even in busy streets or car parks, they work quickly and quietly. Some use jacks to lift lower cars. Once removed, the catalytic converter is sold to scrap dealers for cash.
These parts contain rare metals that are worth more than gold. That’s what makes them a prime target. Most thefts are planned, but some are opportunistic. Without clear markings or alarms, your vehicle becomes an easy target.

How to Prevent Catalytic Converter Theft: 8 Practical Tips
Catalytic converter theft is quick and costly. However, motorists can take a combination of simple and proactive steps to reduce the risk. Here are eight tips to protect your vehicle:
a. Park Smart and Stay Visible
Always park in well-lit, busy areas or secure garages whenever possible. Thieves prefer dark, secluded spots where they’re less likely to be seen.
b. Opt for Secure Parking Facilities
If at home, park your vehicle in a locked garage. If using a driveway, park close to your house or a wall to restrict access underneath the car.
c. Install a Catalytic Converter Lock or Cage
Invest in a professionally-fitted catalytic converter guard, cage, or clamp. These physical barriers dramatically increase the time and effort required for theft, acting as a strong deterrent.
d. Mark Your Converter with Unique ID or SmartWater
Police and insurers recommend marking your catalytic converter with a unique serial number, engraving, or SmartWater forensic liquid. This aids tracing, deters thieves, and helps catch illegal scrap dealers.
e. Install Car Alarms and Tilt Sensors
Upgrade your car’s security system with a sensitive alarm, especially one that detects jacking or tilting. These alarms can alert you to any tampering before thieves succeed.
f. Park to Block Access to the Exhaust
When possible, park low vehicles tight against a wall or fence, or park larger vehicles close beside or behind, to reduce space for thieves to work.
g. Adjust Your Driveway Security
Use security lighting (motion-activated), CCTV, or even driveway posts or bollards to increase visibility and complicate access for would-be criminals.
h. Stay Informed: Know If Your Model Is at Risk
Hybrid cars, SUVs, vans, and models like the Toyota Prius and Honda Jazz are particularly targeted. If you own a high-risk model, be extra vigilant and consider further security upgrades.
What to Do If Your Catalytic Converter Is Stolen?
If your catalytic converter has been stolen, stay calm and follow these steps quickly.
a. Don’t drive the car: Driving without a catalytic converter is unsafe and illegal, which could result in a fine of up to £1,000 for cars or £2,500 for vans. It also damages your engine. You’ll likely hear a loud noise or feel the car running rough. Call a recovery service instead.
b. Report the theft to the police: Use the non-emergency number (101) or report online. Provide as much detail as possible. Ask for a crime reference number, which you’ll need for insurance.
c. Contact your insurer: Let your insurance provider know what’s happened. Some policies cover catalytic converter theft, but you may need to pay an excess.
d. Take photos and check CCTV: Photograph the damage and note anything unusual. If your car was parked near cameras, ask for the footage.
e. Inform your mechanic: A trusted garage can confirm the theft and check if the car is damaged in some other area. Replacement and repairs may take time, especially if parts are on back order.
Will Insurance Cover Catalytic Converter Theft?
Yes, most fully comprehensive car insurance policies do cover catalytic converter theft. However, the level of cover depends on your policy. If you only have third-party insurance, you’re unlikely to be protected. Third-party, fire and theft policies might include it, but always check the details with your provider.
You’ll still have to pay the policy excess, which can range from £100 to £500 depending on your insurer. This amount is deducted from your claim payout, so it’s worth considering whether making a claim is financially sensible.
Also, making a claim could affect your no-claims discount. Some drivers choose to pay for repairs privately to avoid higher premiums later. It’s a good idea to ask your insurer how a claim would impact your record.
To start your claim, you must report the theft to the police and get a crime reference number. Then contact your insurer as soon as possible. Some insurers may ask whether your catalytic converter was marked or if your car had extra security fitted, so having those measures in place could help your case.
Frequently Asked Questions
Why are hybrid vehicles more targeted?
Hybrid vehicles are prime targets because their catalytic converters are cleaner and less used. This means they contain higher amounts of valuable metals like platinum, palladium, and rhodium.
Thieves know they can fetch more cash for converters taken from hybrids, especially popular models like the Toyota Prius or Lexus RX. The risk is higher if your hybrid doesn’t have protective measures in place.
Can I drive without a catalytic converter?
Technically, yes! But it’s illegal and dangerous. Your vehicle will fail the MOT due to harmful emissions. You’ll also notice increased engine noise and reduced fuel efficiency. Driving without one could lead to fines, points on your licence, or prosecution under UK environmental laws. Always replace it before returning to the road.
How much is a stolen catalytic converter worth?
The street value of a stolen catalytic converter can range from £150 to over £500. However, luxury or hybrid car converters may fetch over £1,000. Prices vary based on the amount of precious metal inside. That’s why thieves target specific makes and models.
Will a catalytic converter theft show up on an HPI check?
No, HPI checks don’t list catalytic converter thefts. They only report major incidents like accidents, write-offs, or financial issues. If a stolen part was replaced and the car passed its MOT, there’s no record on HPI. To be safe, always inspect the undercarriage and service history when buying a used car.
How can I check if my converter is marked or registered?
You can check for a visible mark, engraving, or forensic label under the car. Many garages apply SmartWater or etching kits during servicing. If unsure, ask your mechanic to inspect it. You can also register your catalytic converter with a database like Retainagroup or SmartWater. This helps police track it if it is stolen.
Conclusion: Catalytic Converter Theft
Catalytic converter theft isn’t just annoying. It’s expensive, disruptive, and happening more than ever. Ignoring the risk could leave you with a huge repair bill and your car off the road.
A few smart steps today can stop thieves in their tracks. Lock it, mark it, park it wisely, and stay alert to the warning signs.
