London boroughs that present the highest risk of catalytic converter theft

Top 5 hotspots for catalytic converter theft

Enfield has seen both the most cases and the highest catalytic converter theft probability, with a rate of 1.8 per 1000 population.

Newham is a close second, with a 1.7 per 1000 population, followed by Haringey, which had the same rate, but with almost 100 fewer cases. Lewisham and Redbridge both had 1.6 per 1000 population rates of interferences with vehicles.

Catalytic converter theft across time

In the first month of 2022 there were 785 CAT theft reports, lowering the estimated monthly catalytic converter theft odds of previous years.

While the 2022 monthly CAT converter theft rates are the lowest in three years, mainly thanks to a directed effort by UK police, the rates still exceed pre-2019 figures.

Additionally, current reports released by the Metropolitan Police Service only account for one month. Thus, the real car CAT theft odds per month are expected to increase in the future.

At a glance: Change in motor vehicle interference cases

The rates of motor vehicle interference reports have fallen under the 5-year average rate. However, compared to 2021, the first few months of 2022 have seen higher rates of interferences with vehicles, resulting in a slightly higher yearly average.

In other words, 2022 is the first year when interferences with vehicles have not decreased, ever since 2019.

The recent increase in reports is even more aggravating when focusing solely on car catalyser theft rates (as an increasing share of all motor vehicle interferences).

Relevance for catalytic converter theft

In 2018, reports of stolen catalytic converters made up less than a tenth of all vehicle interferences. By 2019, they were more than half.

Starting with 2020, the rates of vehicle interference and car catalyser theft rates became more and more correlated.

Three conclusions on catalytic converter theft

• The motor vehicle interference reports reflect more and more the rates of car catalyser theft.
• Other instances of vehicle interference reports have decreased, leaving only CAT theft to make the largest share.
• Even if overall tampering with cars has decreased, CAT converter theft stagnated or slightly increased.

“A crime that hardly existed in 2017…”

Just as Lib Dem London Assembly Leader Caroline Pidgeon claims, thefts of catalytic converters were a non-existent problem in 2017 and prior.

The 173 reports of the crime made up one seventy-eighth of the total cases of motor vehicle interference. The fraction of car catalyser theft was non-existent.

“…soared in 2019…”

The first signs of a growing criminal issue arose back in 2019 when thefts of catalytic converters still made up just over half of all interferences.

However, albeit 2019 was the peak year for car tampering, this was not the case for car catalyser thefts.

“…and remains worryingly high”

Rates of stolen catalysts peaked back in 2020, only falling since. However. Looking across the timeline, the 2022 catalytic converter odds are still worryingly high.

Assembly member Caroline Pidgeon was the first politician to pay attention to the emerging issue. However, car catalyser theft has become a concern for many politicians, as well as an ongoing thorn in the side of the Metropolitan Police Service.

Public opinion on catalytic converter theft

The contentious subject of the ongoing CAT converter theft crisis has been discussed if not tackled both in the House of Commons and the House of Lords.

House of Commons

Sir Robert Neill, the conservative constituent representing Bromley and Chislehurst, raised the issue with the Minister of Crime and Policing.

Whether the “honourable Friend” did so effectively is up to debate. He was right to draw attention to the ongoing issue, despite falling rates across the country.

However, it was the vivid and inflammatory imagery of shadow crime gangs of members armed with baseball bats threatening violence for the sake of an extra catalyser that may have skirted the edges of fact and fiction.

In truth, official sources correctly portray catalytic convertor theft as a quick, covert, and mostly non-violent crime.

However, the House of Commons discourse around CAT thefts does draw some correct conclusions: the need to strengthen the 2013 Scrap Metal Dealers Act and the issue’s origin and catalyst being a growing market price of valuable metals.

House of Lords

Since the Conservatives in the House of Commons were so hard on the issue that edged on the inflammatory, we could only double our expectations for the House of Lords.

However, the upper house debate was anything but that.

Lord Berkely of Knighton, House of Lords crossbencher and receiver of the Guinness Prize for Composition, started the discussion around the increasing CAT converter theft rates.

A formidable foe

Conservative Baroness of Barran, was on the other side of this 2019 debate. Her input went mainly along the lines of characterising cat catalyser theft as a real but diminishing issue, apropos the falling rates since, perhaps irrelevantly, 2013, compared to the 2018 figures.

We do not need to benefit from hindsight to not take a Conservative’s word for granted. However, truth be told, recent years have done a great job in falsifying the Baroness’s wishful claim.

Perhaps specific to a noble, Lord Berkley of Knighton’s interest in the crime was “piqued” only following his own instance of being “catalytically bereaved”, i.e., having this CAT converter stolen.

Erring Earl

Earl Attlee also interceded into the riveting debate turned dilettante discussion on security devices on the part of the Baroness. John Riched Attlee contended with his cunning that perhaps the recent increase in the theft of catalysers is a social issue earning him a place in the run for the most obvious statement in the British Parliament.

But, render onto Cesar what is rightfully his, the Earl is not wrong. Where he is completely wrong, however, in his pointing at the prison system and its failure to “reeducate” inmates in finding “legitimate economic” activities.

Perhaps we may be the mad ones, but instead of teaching the disenfranchised economic responsibility, a man of such power and insightfulness could help provide the people of Britain with some decent opportunities to work legitimately.

Earl Attlee was finally sidelined in the discussion, perhaps in a rare instance of friendly fire, coming from the Baroness, aimed at the Earl’s extensive knowledge of the British correctional system.

High metal prices, low police budgets

Lib Dem Lord Paddick then moved the attention towards two issues that fueled the higher catalytic converter theft odds: high precious metal prices and dwindling police budgets.

While agreeing, the Baroness insisted that the higher rates in catalyst theft rates were a success in police recording since overall crime in the disputed areas went down by 73%. Once again, analyses like that for the odds of car theft in the UK show that, albeit Britain is a safer place, car-related crime has surged, with a 7.4% increase within the last year.

Lord Faulkner of Worcester drew attention to the role of the metal theft task force in the (then) new increase in stolen catalytic converters.

While the force managed to curve past surges in theft rates for CAT converters since its introduction by the 2013 Scrap Metal Dealers Act, it was soon “abandoned” despite its effectiveness.

Britain could benefit from a stronger metal theft task force even today, and there are signs that authorities are engaging in a new campaign against the theft of catalytic converters.

In some sense, authorities have already taken the steps to alleviate the issue, with the British Transport Police coordinating a multi-agency operation to reduce catalytic converter theft already in 2021.

Catalytic converter price UK

Catalysts are expensive car parts. The loss of one can come with a repair bill in the thousands.

Stolen catalytic converter price for victims

A new catalyst will cost you between £180 and £360, depending on your car and current stock. Unfortunately, its installation is much costlier.

The overall price for such an event can reach £2,000 for most car owners that fell victim to the theft of catalytic converters.

Stolen catalytic converter price for thieves

A cat converter can sell for hundreds of pounds in cash on the black market, even as scrap.

The key fact about catalysts is that they are valuable both as car parts and scrap metal. Nevertheless, considering the £2,000 bill accompanying the replacement of one, thieves hardly make a profit.

Why are catalytic converters valuable?

Catalysts contain high amounts of palladium and rhodium, both metals that are more expensive than gold. They also contain platinum, another precious metal.

Current prices for precious metals present in catalysts

• Palladium – £1,853.27 / oz
• Rhodium – £12,503.23 / oz
• Platinum – £789.62 / oz

Which cars have the most expensive catalytic converter?

Most recent reports point towards the Ferrari F430, which has a CAT with a price tag of over £3,273.

In general, exotic catalysers, i.e., those fitted for foreign cars, can go up to £970, while torpedo CATs have an upper price bound of £1,085.

Aftermarket versions can sell for as low as £18. Still, the foil catalysts are the cheapest, with some selling for as low as £6.

Which are the most stolen catalytic converters?

Honda and Toyota models, in general, have been the most targeted models for having their catalytic converters stolen.

Honda Jazz models faced 808 thefts in 2021 and 54 in January 2022, with Toyota Prius models having their CAT stolen 801 times in 2021 and 58 times in January. These two models are the leading ones in the top cars for catalytic converter theft.

What is a catalytic converter?

Catalysers are exhaust emission control devices that turn pollutant fumes into less harmful ones using a catalyst.

As their denomination would imply, catalytic converters are placed along the exhaust pipe. All fumes generated by the car’s combustion process go through the catalyser. By way of a redox reaction, the catalytic agents reduce the level of pollution of the exiting fumes.

What does a catalytic converter look like?

Catalysers often resemble a tubular chamber placed along the exhaust pipe. You can most often recognise it as a bump or bulge on the exhaust pipe.

Some CAT converters will have two functional parts, along with an extra parallel valve. The first part is a cold start catalyst, while the other subsequent one is a standard three-way catalyst.

Where is a catalytic converter on a car?

CAT converters are located underneath the car’s body, slightly behind the front wheels.

They often are accompanied by a heat shield, as catalysers can overheat due to excessive amounts of unburned gas. This case often occurs either due to spark plugs misfiring (in which case, the fuel is not correctly burned), or leaky exhaust valves.

Do all cars have catalytic converters?

CAT converters gained widespread use only after the 1970s. Older models are not fitted with the systems.

Additionally, the newer electric cars do not have catalysers since these models do not release pollutant fumes.

Do diesel cars have catalytic converters?

Yes, although diesel motor systems have a specific type of CAT converters composed of three functional parts.

The diesel catalytic converter

• DOC: the diesel oxidation catalyst is the first and smallest component. It resembles the gasoline variant. The DOC is the most valuable as it contains larger amounts of platinum and palladium.
• DPF: the diesel particulate filter completes a process called regeneration, i.e., turning a byproduct called particulates or soot into CO2 and water through catalysis. It also contains small amounts of platinum and palladium.
• SCR: the selective catalytic reduction aims to lower NOx gases by turning them into nitrogen and oxygen. Since diesel exhaust has high levels of oxygen already, the SCR does not need to contain rhodium.

Why are catalytic converters stolen?

The theft of catalytic converters is motivated by the piece’s high value resulting from the presence of precious metals palladium, platinum, and rhodium.

How much is a stolen catalytic converter worth?

The catalytic converter price varies depending on the car model it is fitted for, whether it is functional, or, in case it is sold for scrap, the amount of precious metal in it.

Catalytic converter price variations per precious metal amounts

Which cars are most likely to have catalytic converters stolen?

Thieves have historically gone for the CAT converters of easily available cars, like Prius and Jazz models.

Additionally, criminals will aim to find unprotected vehicles, i.e., models that lack protection shields or that are parked in public places, partially on the curb.

Which cars are least likely to have catalytic converters stolen?

If your car has security systems and it is parked in a private space, such as a personal garage, there is little to no chance of losing your catalyser.

How to prevent catalytic converter theft

• Park in well-lit areas or close to public entrances
• Install surveillance systems around your parking area (motion-sensitive lights, cameras, etc.)
• Paint your CAT converter to deter subsequent buyers
• Etch your license plate number or your VIN onto the CAT converter
• Learn if your car is a possible target. Hybrids, SUVs or trucks can be at higher risk
• Ask a mechanic to weld the exhaust clamps onto your CAT converter if possible.
• Buy an anti-theft device

What is the best catalytic converter anti-theft device?

A universal CAT alarm is an accessible and effective option. The system has its faults, and it will mainly alarm you, not protect your catalyser.

A CAT converter lock is a more direct protection device. Systems like the CatClamp MAXX provide a cage-like contraption that will foil any criminal’s attempt to take your CAT. However, locks are considerably more expensive

Some popular models that are prone to the theft of their catalytic converters can be fitted with a catalyser shield, which is a cheap and easy-to-use anti-theft addition.
