What's Your Catalytic Converter Worth for Scrap? UK Prices 2026 | Amber Autos

Catalytic converters are by far the most valuable single part on most UK cars — sometimes worth more than the rest of the vehicle put together. We see hundreds of them come through our Southend yard every year, and the price difference between the cheapest and the most valuable can be staggering: £20 for a small petrol hatchback cat at the bottom end, £2,000+ for a clean Toyota Prius unit at the top.

Most articles on catalytic converter scrap prices are written by buyers trying to set expectations low, or by sites with no actual scrap data guessing at numbers. As a licensed Authorised Treatment Facility that buys, removes and processes cats every week, we get to see what they actually fetch on the UK market — and we can be honest about it.

This guide covers what your catalytic converter is realistically worth in 2026, why the prices vary so wildly, how the law works, and how to protect yourself from being underpaid or, worse, having yours stolen.

Quick Answer: What's a Catalytic Converter Worth?

For most UK cars in 2026, the realistic scrap value range is:

These ranges shift constantly because they track precious metal markets, which we'll explain in a moment. The prices above reflect early 2026 UK market conditions. If you're after a precise number for your specific vehicle, the only honest answer is: get a quote from a licensed dealer, ideally a few, and compare.

Why Catalytic Converters Are So Valuable

Inside every catalytic converter is a ceramic honeycomb coated with three precious metals: platinum, palladium, and rhodium. Together these are called Platinum Group Metals, or PGMs. They're not filler — they're what make the cat actually work, triggering the chemical reactions that turn harmful exhaust gases into less harmful ones.

Here's why they're so expensive:

• Platinum: ~£900 per ounce in early 2026. Used heavily in diesel catalysts.
• Palladium: ~£800 per ounce. Used heavily in petrol catalysts.
• Rhodium: £8,000–£12,000 per ounce — roughly ten times the price of gold. Irreplaceable for reducing nitrogen oxides. Used in tiny amounts but worth the most by weight.

A typical UK car catalytic converter contains between 3 and 15 grams of combined PGMs. That doesn't sound like much, but when rhodium is £350+ per gram, even tiny amounts add up fast. A converter with 0.5g of rhodium alone has £175 worth of metal in it.

This is also why prices are so volatile. When rhodium spiked above £15,000/oz briefly in 2021, certain catalytic converters doubled in scrap value overnight. When PGM markets soften, prices come down with them. Anyone quoting you a fixed price weeks in advance isn't being straight with you — the metal market changes daily.

Which Cars Have the Most Valuable Cats?

The pattern we see at our yard is consistent year after year. From most to least valuable, broadly:

1. Hybrid vehicles — the top of the table

Hybrid catalytic converters are designed to work efficiently even at low exhaust temperatures, because the petrol engine cycles on and off. That means heavier PGM loading. The Toyota Prius is legendary in the scrap trade — a clean Prius cat can fetch £300–£800 in normal market conditions, and we've seen them go higher. The Honda Insight, Lexus hybrids and Toyota RAV4 hybrid are in the same league.

2. Older Japanese petrol cars

Pre-2010 Hondas (Accord, Civic Type R) and Toyotas (Avensis, Land Cruiser) often have surprisingly valuable cats — heavier metal loadings than modern equivalents. A 2005 Honda Accord cat can be worth more than a brand-new equivalent from a budget hatchback.

3. European luxury — BMW, Mercedes, Audi

Premium European brands typically meet stricter emissions standards, which means richer catalyst formulations. BMW M-series and AMG units in particular carry serious metal loadings. Diesel variants are less valuable than the petrol equivalents — platinum dominates their formulations.

4. SUVs and 4x4s

Larger engines = larger catalysts = more PGM. Range Rovers, BMW X5s and larger SUVs typically have multiple cats (a main one plus pre-cats), which adds up.

5. Standard petrol cars

Ford Focus, Vauxhall Astra, Volkswagen Golf, modern Renault and PSA group cars — typical mid-range three-way catalysts. £40–£150 is the usual band.

6. Modern diesel cars

Diesel cats and DPFs (diesel particulate filters) use platinum-heavy formulations with less palladium and rhodium. They're still worth money, but typically less than petrol equivalents. A modern Euro 6 diesel DPF might fetch £40–£100.

Bottom of the table: aftermarket cats

Cheap aftermarket replacement catalytic converters — the ones often fitted after a theft or MOT failure — contain very little PGM, sometimes as little as 5% of an OEM unit. Their scrap value is typically £2–£10. If your cat has been replaced at some point, check the brand stamp — an OEM cat is worth multiples of an aftermarket one.

How Scrap Buyers Actually Calculate the Price

Behind the scenes, the process is fairly mechanical. A reputable buyer:

1. Identifies the unit from manufacturer codes stamped on the casing. Most cats have a stamped or laser-etched OEM number.
2. Looks up the average PGM content from a reference database (typically tools like AutoCatalystMarket or proprietary refiner databases).
3. Checks today's PGM prices on the precious metal markets.
4. Calculates the recoverable metal value based on those two numbers.
5. Deducts processing and refining costs — usually 20–40% of the gross value, depending on volume and the buyer's margins.
6. Quotes the net price to you.

If you're getting three quotes and one is significantly higher than the others, treat it with suspicion — either they've made an error, or it's bait pricing that'll drop on collection. Reputable buyers tend to cluster within 10–15% of each other.

The Law: What You Must Know Before Selling

The UK scrap metal trade is regulated by the Scrap Metal Dealers Act 2013, designed specifically to combat metal theft and the trade in stolen cats. The rules are straightforward but worth knowing:

• No cash payments. Ever. All scrap transactions must be by bank transfer, cheque, or store voucher. If anyone offers you cash for a catalytic converter, they are breaking the law and the cat is likely going into an unlawful supply chain.
• Photo ID required. The buyer must verify your identity with a valid passport, driving licence or other photo ID, and record the transaction.
• The buyer must be licensed. All UK scrap metal dealers must hold a licence issued by their local authority. Ask to see it. Unlicensed buyers cannot legally transact, and dealing with them puts you on the wrong side of the law.
• You must own what you're selling. Self-explanatory, but worth saying. Selling someone else's catalytic converter is theft, full stop.

At Amber Autos we operate strictly within these rules because we have to — we're a licensed Authorised Treatment Facility with an Environment Agency permit (JP3029SM) and our business depends on it. Every catalytic converter we buy is paid for by bank transfer with full documentation. If a buyer is offering you something different, they're either unlicensed or risking their licence — neither of which is a good sign.

Should You Scrap Just the Cat, or the Whole Car?

This is the question we get asked most often. The honest answer depends on the car. Three scenarios:

Scenario 1: Car is sound, just had a failed cat

Sell the cat on its own. A failed catalytic converter (P0420 code, MOT emissions failure) usually still has all its PGM content intact — the ceramic substrate is just clogged or damaged. The scrap value is the same whether it's working or not. Replace with a new or refurbished unit and carry on driving.

Scenario 2: Car is end-of-life, with the cat still fitted

Scrap the whole car through a licensed ATF and let them handle the cat as part of the deal. You'll typically get the cat value plus the kerb weight scrap value of the rest of the car. We've covered how that's worked out in our scrap car prices Essex guide.

Scenario 3: Car had its cat stolen, isn't worth replacing

Common situation. A 2008 hatchback worth £400 has its cat stolen, and a replacement quote comes in at £800. The maths is brutal. In this case, scrapping the whole car (even without the cat) is usually the right move — we still pay scrap value on the kerb weight regardless of whether the cat's still there. Get a quote before assuming the car's worthless.

Catalytic Converter Theft: An Honest Word

Cat theft in the UK has been a real and growing problem since around 2019, driven by surging PGM prices. Thieves can remove a catalytic converter in under three minutes with a battery-powered cutting tool, often in broad daylight outside a supermarket or workplace.

If you drive one of the high-value vehicles listed above — especially a hybrid — assume you're a target. The Toyota Prius has been the single most-stolen-cat vehicle in the UK for years running.

What you can do:

• Park defensively. Garage if you have one. Drive close to a wall or kerb so they can't get a jack underneath easily. Park where there's CCTV.
• Fit a cat lock or shield. Aftermarket cages and locking plates make removal take 15+ minutes instead of 3 — usually enough to deter opportunistic thieves. Halfords and specialist suppliers fit these for £150–£300 depending on car.
• Mark your cat. Catloc and SmartWater both offer marking systems that link the cat to your registration. Doesn't prevent theft but helps police trace stolen units.
• Listen for cutting noises. If you hear an angle grinder near your parked car, dial 999 — don't approach. Most thefts are done by organised groups.

If yours has been stolen: report to police immediately, contact your insurer (comprehensive cover usually pays out), and get the car off the road until it's repaired. Driving without a cat fails the MOT and is also unwise long-term — the louder exhaust will draw police attention.

Getting the Best Price: Practical Tips

• Identify your cat before you sell. Find the OEM code stamped on the casing — usually 5–10 alphanumeric characters. Photograph it. This lets buyers price it accurately rather than guessing.
• Get two or three quotes. Prices vary by 10–20% between licensed dealers based on their margins and current refining contracts. A few phone calls can add £30–£100 to your payout.
• Don't accept cash quotes. They're illegal and they signal a buyer who'll find a reason to lower the price at collection.
• Don't pre-cut or damage the unit. Some people think cutting it open shows what's inside — it just makes it harder for a refiner to process and reduces your price. Sell it whole.
• Watch the precious metal markets. If you're not in a rush and PGM prices are dropping, wait. If they're rising, sell. AutoCatalystMarket and Heraeus publish daily PGM prices.
• Don't trust unsolicited "we buy cats" leaflets. These are usually unlicensed buyers operating illegally. Stick to licensed scrap dealers with a physical address and a verifiable licence number.

Frequently Asked Questions

How much is a catalytic converter worth for scrap in the UK?

Most UK catalytic converters scrap for between £20 and £400, with rare high-value units from hybrids and luxury cars reaching £800–£2,500. The price depends almost entirely on the platinum, palladium and rhodium content inside, which varies massively by make, model and engine. A small petrol hatchback cat might be £30–£80, while a Toyota Prius cat can fetch £400+ on a good day.

Which cars have the most valuable catalytic converters?

Hybrid vehicles consistently top the list — the Toyota Prius, Honda Insight and earlier hybrid SUVs are well known for high-PGM cats. Older Japanese petrol cars (Honda Accord, Toyota Avensis) and European luxury cars (BMW, Mercedes, Audi) also carry valuable units. Diesel cars tend to be worth less because their cats use cheaper platinum-heavy formulations. Modern small petrol cars have the lowest-value cats.

Why are catalytic converters so valuable?

Catalytic converters contain three precious metals — platinum, palladium, and rhodium — coated onto a ceramic honeycomb inside. Rhodium alone trades at £8,000–£12,000 per ounce, roughly ten times the price of gold. A typical UK car cat contains 3–15 grams of combined PGMs, which is why even a small unit can be worth more than the rest of the exhaust system put together.

Is it legal to sell a catalytic converter in the UK?

Yes — if you own it and you sell it to a licensed scrap metal dealer. Under the Scrap Metal Dealers Act 2013, all transactions must be by bank transfer (no cash), the buyer must verify your ID, and the sale must be recorded. If you're offered cash with no paperwork, that's an illegal transaction and a strong sign the buyer is dealing in stolen units. Walk away.

Can I scrap a catalytic converter separately from the car?

Yes, but you may get more by scrapping the whole car. If the car is otherwise sound and worth selling, take the cat out and sell it on its own. If the car is end-of-life anyway, a licensed ATF will value the cat as part of the overall scrap quote, and you avoid the hassle of removing it yourself. We always tell people whichever option pays more — sometimes it's the cat alone, sometimes it's the whole car.

What should I do if my catalytic converter is stolen?

Report it to police immediately (101 or online), then contact your insurer — comprehensive cover usually pays out. Your car will be drivable but extremely loud and will fail an MOT. Don't try to drive it long-term without one. Replacement costs £500–£2,500 depending on car. If replacement makes the car uneconomic, scrapping with a licensed ATF may be the better option — we still value cars with stolen cats based on the rest of the vehicle.
