Getting a price for a replacement catalytic converter on a Ford Fiesta is simpler than most people expect. At Catman, we supply quality replacement cats for Fiesta models across the UK. Confirm your vehicle, get a price, arrange delivery. We’re one of the UK’s leading catalytic converter suppliers, with a trusted supply chain, reliable parts, and a minimum 12-month guarantee on everything we sell. Enter your registration or get in touch and we’ll come back to you fast.
The Ford Fiesta has been through several major updates, and the catalytic converter you need depends on more than just the year your car was made. Engine type, displacement, and emissions rating all affect the spec, and fitting the wrong cat creates problems that aren’t always obvious until you’re dealing with an MOT failure or a performance issue you can’t quite place.
We cover MK6 and MK7 Fiestas, the ST-Line, EcoBoost petrol variants, and models from 2018 onwards built to Euro 6 standards. Common engine codes across those generations include the 1.0 EcoBoost three-cylinder, the 1.25 Zetec, and the 1.4 and 1.6 petrol variants, each with its own catalyst requirements. The EcoBoost in particular uses a more complex cat than older petrol variants, designed to meet stricter cold-start emissions limits, which affects both the spec and the price of the replacement part.
The quickest way to confirm the right part is your registration number. It pulls your car’s exact spec and removes any guesswork. Enter it through our lookup or include it when you contact us.
It sits in the exhaust system between the engine and the silencer and converts harmful gases, primarily hydrocarbons, carbon monoxide, and nitrogen oxides, into less harmful substances before they exit the tailpipe. It does this through a chemical reaction using a coated internal filter of platinum, palladium, and rhodium, triggered by heat as the exhaust warms up.
The quality of those coatings matters when
choosing a replacement. Cheaper cats use lower concentrations of the active metals, which affects how well they convert exhaust gases and how long they stay within emissions limits.
On a Fiesta subject to MOT emissions testing, a cat that passes on day one but degrades quickly isn’t good value, whatever the upfront price.
Pricing varies, and it’s worth knowing why before you start comparing numbers.
The main factors are your model generation and engine type. A replacement cat for an older MK6 with a 1.25 petrol sits at a different price point to one for a 2018+ Fiesta EcoBoost built to Euro 6 standards, as the latter is built to a higher spec to meet stricter emissions requirements. Turbo petrol variants can differ again.
We don’t publish a fixed price list because the right number only makes sense once we’ve confirmed your vehicle.
Once we have your registration, we’ll come back with the best price we can offer. We’re not sourcing cheap catalogue stock just to win on headline price, and the pricing reflects that.
We ship UK-wide with fast turnaround and tracking from dispatch.
Our process isn’t a standard ecommerce checkout. You enquire, we confirm compatibility, you get a price, we ship. That extra step exists because getting the right cat to the right Fiesta matters more than processing an order quickly and dealing with a return later. The two steps are part of the same process, and treating them that way is what keeps things straightforward from your end.
A catalytic converter can last well over 100,000 miles on a well-maintained car. It can also fail much sooner if the car has been running rich, taken physical damage, or spent most of its life on short urban trips where the exhaust never fully heats up.
When it starts to fail, there are usually signs. A sulphur or rotten egg smell from the exhaust is one of the more obvious ones. Reduced power, particularly noticeable at higher revs, is another. Your engine management light may come on, often with a fault code linked to catalyst efficiency. A rattle from underneath usually means the internal substrate has begun to break down, which is a clear sign the cat needs replacing rather than investigating further.
From an MOT perspective, a failing cat is a real risk. Petrol Fiestas are subject to emissions testing, and a degraded catalytic converter will often push readings over the limit. Failing and then replacing still means the same part cost, plus the retest fee. Replacing before your MOT is the cheaper path.
If you’re not certain whether replacement is the right call, get in touch before ordering. We’re happy to talk it through.
We supply catalytic converters for MK6 and MK7 Fiestas, the ST-Line, and EcoBoost petrol variants across multiple engine codes. We also cover 2018 and newer models, including those built to Euro 6 standards. Hatchback body types across all listed generations.
If your Fiesta isn’t listed here or you’re unsure about your engine code, just get in touch and we’ll confirm quickly.
We only work with manufacturers whose parts we’re confident in. In practice, that means we don’t stock parts that don’t consistently meet emissions specifications or that show early failure rates in fitment. If a supplier doesn’t meet that standard, we don’t use them.
Every cat we supply meets current UK and EU emission standards and carries a minimum 12-month guarantee.
We specialise in catalytic converters. What that means in practice is that we understand fitment requirements across engine codes and model generations in a way a generalist parts retailer doesn’t.
When a customer contacts us with a registration, we’re not cross-referencing a generic catalogue. We know the product.
Our pricing is competitive, our supply chain is reliable, and the 12-month guarantee covers every part we sell.
The Catman always offers very high-quality service, efficient and speedy, whilst offering truly amazing value for money. The Catman will only supply from well-established suppliers that offer substantial guarantees. To this end, all of the products are guaranteed for a minimum of 12 months.
