Cambelt replacement cost UK
fitted at an independent garage · parts and labour included
- With water pump +£90–£150
- Typical time 2–6 h
- Dealer +50%
A cambelt replacement in the UK costs £300–£880 fitted at an independent garage, depending on the engine. A conventional belt on a small petrol runs £300–£520, while the oil-immersed “wet belts” in Ford EcoBoost engines push the job past £850. Adding the water pump costs £90–£150 more and is usually worth it. Main dealers charge roughly 50% more. Use the calculator below for your model, then compare live quotes.

Cambelt replacement cost by make and model
Prices below are for an independent garage, parts and labour included, for the belt-engined versions of each model. Several popular cars use a timing chain instead of a cambelt — those have no scheduled replacement, which is why the rows below say so rather than showing a price.
| Car | Belt or chain? | Cambelt, fitted | + water pump |
|---|---|---|---|
| Ford Fiesta | Wet belt (1.0 EcoBoost) | £480–£850 | £560–£950 |
| Ford Focus | Wet belt / belt | £480–£880 | £560–£980 |
| Vauxhall Corsa | Belt, chain or wet belt (1.2 PureTech) by engine | £300–£480 | £400–£600 |
| Vauxhall Astra | Belt, chain or wet belt by generation | £320–£520 | £420–£640 |
| Volkswagen Golf | Belt (most engines) | £350–£560 | £450–£680 |
| Volkswagen Polo | Belt (most engines) | £320–£520 | £420–£640 |

What affects the price of a cambelt replacement
Access is everything. The belt itself costs £30–£60 — the price is in reaching it. On a transverse small petrol the job is 2–3 hours; on engines where mounts, covers and auxiliary systems have to come off first it stretches to 5–6 hours. Same belt, very different bill.
Wet belts cost more — every time. Ford’s 1.0 EcoBoost and the Peugeot/Citroën 1.2 PureTech run the belt inside the engine, bathed in oil. Replacement means draining oil, removing the sump area covers and strict cleanliness — see the wet belt section for why these jobs start where conventional belts finish.
The water pump decision moves the total. On most engines the cambelt drives the water pump, so garages quote both together — £90–£150 more now versus the full labour bill again if the pump fails later. It’s the same “labour is already paid for” logic as the flywheel in a clutch replacement, and the same dealer-vs-independent maths applies as with brakes — see the full comparison.
What’s included in a cambelt replacement
A proper cambelt job fits a full timing kit, not just the belt: the belt itself, the tensioner, and the idler pulleys. The tensioner and idlers wear at the same rate as the belt — a new belt run over a tired tensioner can fail long before its interval, with exactly the same consequences as a snapped belt. Reputable garages won’t fit a belt alone, and you shouldn’t ask them to.
Where the belt drives the water pump, the pump is usually added to the kit. The job finishes with fresh coolant where the pump was disturbed, and on wet-belt engines an oil and filter change is part of the procedure, not an extra.
| Timing kit (Gates/INA: belt, tensioner, idlers) | £130 |
| Water pump | £70 |
| Labour — 3.5 h × £65 (independent garage) | £227 |
| Coolant and sundries | £25 |
| Typical total | ≈ £450 |
Sits inside the £420–£640 range in the table above. A wet-belt EcoBoost doing the equivalent job lands £150–£300 higher — more labour, plus the oil service built into the procedure.
Cambelt or timing chain — which does your car have?
Roughly half the cars on UK roads don’t have a cambelt at all — they use a timing chain, a metal chain lubricated by engine oil with no scheduled replacement. All modern BMWs, Mercedes, Toyotas and most Hondas are chain-driven; VW, Ford, Vauxhall and the French brands mix belts and chains depending on the engine. The split runs by engine, not by model — a Qashqai 1.5 dCi has a belt, a Qashqai 1.2 petrol has a chain. Even the “chain brands” hide exceptions: the Honda Civic 1.0 VTEC Turbo and the Mercedes A180d both run belts despite the badge’s reputation.
“No scheduled replacement” is not the same as “maintenance-free”. Chains stretch, and some engines are known for it — the BMW N47 diesel’s rear-mounted chain is the most famous UK example, where a worn chain means an engine-out repair costing more than many cambelt jobs put together. Our BMW 1 Series page covers the symptoms and costs. The best protection for any chain engine is boringly simple: on-time oil changes with the correct spec.

Wet belts: why EcoBoost and PureTech cost more
A wet belt (belt-in-oil) runs inside the engine, immersed in oil — Ford’s 1.0 EcoBoost and the PSA 1.2 PureTech are the big UK examples. The design saves fuel and space, but it has an expensive weakness: as the belt ages it can shed rubber particles into the oil, which block the oil pick-up and starve the engine. That failure mode is why both manufacturers have cut the original intervals sharply — many EcoBoosts originally scheduled for 10 years are now recommended at 6–8, and PureTech intervals have been revised more than once. Our dedicated wet belt guide covers the full story, prices and affected engines.
The replacement itself costs more than a conventional belt for structural reasons: the engine has to be part-drained and opened, cleanliness is critical, and an oil and filter change is part of the job. Two rules protect a wet-belt engine between changes: use exactly the oil specification in the handbook (the wrong oil attacks the belt), and treat any oil-pressure warning or rough running as urgent. If you’re buying a used EcoBoost or PureTech, evidence of the belt change is worth real money — our Fiesta page goes deeper on the EcoBoost specifically.
Independent garage vs main dealer vs fast-fit chain
A cambelt is a precision job — timing marks, locking tools, torque specs — but it’s routine precision, and independents do it every week. What changes between garage types is mostly the hourly rate.
| Independent garage | Main dealer | National fast-fit chain | |
|---|---|---|---|
| Typical cambelt price | £300–£880 (baseline) | +50% on average | Close to independent |
| Hourly labour rate | £50–£80 | £120–£180 | £60–£90 |
| Parts fitted | Quality aftermarket kits (Gates, INA, Dayco, SKF) | Genuine branded OEM | Own-brand or aftermarket |
| Warranty on the job | Typically 12 months | 12–24 months | 12 months, honoured nationwide |
| Best for | Out-of-warranty cars — identical kit, lower rate | Wet-belt jobs on newer cars, warranty cars | Fixed advertised prices, convenience |
One caveat worth knowing: Gates and INA manufacture the original belts for most European carmakers, so an independent fitting their kit is fitting factory-grade parts. For wet-belt engines, whoever does the job, insist the invoice lists the belt part number and the oil spec used — it’s your proof at resale.
When to replace a cambelt — 6 triggers
Unlike a clutch, a cambelt gives you almost no warning — it looks fine right up until it isn’t. That’s why replacement is driven by the schedule, not by symptoms. These are the six situations that mean the job is due:
- The mileage interval is reached
Typically 60,000–100,000 miles depending on the engine — the exact figure is in your handbook’s service schedule.
Cost signal: on schedule, this is a planned £300–£880. Past it, you’re carrying the snapped-belt risk below. - The age limit is reached — even at low miles
Rubber degrades with time regardless of use. Most schedules say 4–6 years for conventional belts; a 15,000-mile garage queen still needs the belt at the age limit.
Cost signal: the most commonly missed trigger — low-mileage cars fail belts on age, not wear. - You’ve bought a used car with no proof of the change
No invoice means it hasn’t been done — that’s the only safe assumption. Stickers under the bonnet without paperwork don’t count.
Cost signal: budget the belt into the purchase, or use it to negotiate — the job’s cost off the asking price is a fair ask. - You have a wet-belt engine on the original belt
EcoBoost and PureTech intervals have been revised downwards — the schedule printed in an older handbook may no longer be the manufacturer’s current advice. Our wet belt guide has the engine-by-engine detail.
Cost signal: doing it at 6–8 years is a £480–£980 job. Waiting for oil-starvation damage is an engine. - Oil or coolant is leaking onto the belt
A leaking cam seal or water pump contaminates the belt, and oil-soaked rubber fails early. Any leak in the timing area brings the belt job forward.
Cost signal: fix leak + belt in one labour bill now, or leak + belt + valve damage later. - Noise from the timing cover
A ticking, rattling or whirring from behind the timing cover usually means a dying tensioner or idler — the belt’s support system failing around it.
Cost signal: the one audible warning you may get. A full kit now costs the same as it did last month; ignoring it can cost an engine.
What happens if a cambelt snaps — and why the schedule is cheap
The cambelt keeps the pistons and valves synchronised. On most modern engines — so-called interference engines — the two share the same space at different moments, and only the belt keeps them apart. When it snaps, pistons strike open valves within a single revolution: bent valves, damaged pistons, sometimes a wrecked cylinder head. There is no limp home and no warning light that saves you.
The repair for a snapped belt is engine surgery: typically £1,500–£3,000 at an independent, and beyond the car’s value for many older vehicles — at which point you’re pricing engine replacement or scrapping. Set against that, a scheduled £300–£880 belt change is one of the best-value maintenance jobs in motoring. If the interval is due and money is tight, this is the job to prioritise above almost anything else on the car — it’s the only item on a service schedule where “late” can mean “total loss”. Not sure where yours stands? Check your reg — we’ll flag whether the belt is likely due alongside everything else your MOT history predicts.
How to pay less for a cambelt replacement
Bundle the water pump, aux belt and coolant. Everything in the timing area shares one labour bill. The auxiliary drive belt comes off anyway and costs £15–£30 to renew while it’s off; the pump adds £90–£150 versus a full repeat visit later.
Compare quotes for the same kit. Ask each garage what brand of kit they’re quoting (Gates, INA, Dayco, SKF are the factory suppliers) — then you’re comparing labour rates on identical parts, where £30/hour of difference across a 3–5 hour job is £100–£150.
Time it with other front-of-engine work. If a clutch, water pump leak or engine mount job already has that side of the engine apart, the belt’s marginal labour drops sharply. Ask “what else should we do while it’s open?” — it’s the cheapest question in car ownership.
Use the schedule as a negotiating tool when buying. A used car at or past its belt interval with no invoice is priced wrong — the cost of the job in the table above is a legitimate, evidenced discount to ask for.
Same timing kit, same engine — quotes can differ by £150+. Compare local garages before you book.

How much does a cambelt replacement cost in the UK?
£300–£880 at an independent garage, parts and labour included, depending on the engine. Conventional belts on small petrols sit at £300–£520; oil-immersed wet belts (Ford EcoBoost, PSA PureTech) run £480–£980. Adding the water pump costs £90–£150 more, and main dealers charge roughly 50% extra.
How often should a cambelt be changed?
Typically every 60,000–100,000 miles or 4–6 years, whichever comes first — the exact interval is engine-specific and printed in your service schedule. Wet-belt engines are the exception: several manufacturers have cut original intervals, so check the current recommendation, not the one in an old handbook.
What happens if a cambelt snaps while driving?
On an interference engine — most modern cars — the pistons hit open valves within one revolution. The result is bent valves and often piston or head damage, typically £1,500–£3,000 to repair, and beyond economic repair on many older cars. The engine stops immediately; there’s no limping home.
Does my car have a cambelt or a timing chain?
It varies by engine, not model. BMW, Mercedes, Toyota and most Hondas use chains; Ford, VW, Vauxhall, Audi and the French brands mix both. Your handbook’s service schedule lists a belt interval if there is one — or enter your reg in our checker and we’ll identify the engine for you.
Should I replace the water pump with the cambelt?
If the belt drives it, almost always yes. The pump costs £60–£90 in parts and the labour to reach it is already paid for. A pump failing later means repeating the entire belt-area labour bill — and a leaking pump can contaminate and destroy a fresh belt.
What is a wet belt and why is it a problem?
A wet belt runs inside the engine, immersed in oil — used in Ford’s 1.0 EcoBoost and the PSA 1.2 PureTech. Ageing belts can shed rubber into the oil and starve the engine, which is why intervals have been shortened and why replacement costs more: the engine has to be part-opened and the job includes an oil change.
Can a cambelt really last 10 years?
Some manufacturers originally scheduled 10 years, but rubber degrades with age regardless of mileage, and several of those intervals have since been revised down — most notably on wet-belt engines. For a car you plan to keep, 5–6 years is the prudent ceiling for a conventional belt even at low miles.
Are there warning signs before a cambelt fails?
Usually none — a belt looks fine until it snaps, which is why replacement is schedule-driven. The exceptions worth acting on: ticking or rattling from the timing cover (a dying tensioner), visible oil or coolant leaking into the timing area, or misfires on a wet-belt engine.
Do timing chains ever need replacing?
Not on a schedule, but they’re not immortal — chains stretch, and some engines are known for it (the BMW N47 diesel is the famous UK case, an engine-out repair). A rattling chain on cold start needs investigating promptly. The best chain protection is on-time oil changes with the correct specification.
Is it worth buying a car with no cambelt history?
Only at the right price. With no invoice, the safe assumption is the belt hasn’t been done — so deduct the cost of the job (see the table above) from what you’re willing to pay, and book the change straight after purchase. On wet-belt engines, missing history should be treated as a bigger red flag.
How long does a cambelt replacement take?
Around 2–3 hours on an accessible small petrol, 3–5 hours on most family cars, and up to 6 hours on wet-belt engines or where mounts and covers have to come off. Most garages complete the job within a day; wet-belt jobs are sometimes booked as a full day.
Is a cambelt covered by warranty or insurance?
Routine replacement isn’t — it’s scheduled maintenance, like servicing. If a belt fails inside the manufacturer’s stated interval with full service history, the resulting damage may be a warranty claim. Insurance doesn’t cover it; some extended warranties cover consequential damage but not the belt itself. Keep every invoice.
