Last updated: July 2026 — every price on this page was checked against the named UK sources on 7 July 2026.
A Ford 1.0 EcoBoost wet belt replacement costs £458–£524 at an independent garage (belt only, Focus estimate) and £750–£851 at a franchise dealer, according to ClickMechanic — while the average real-world quote on FixMyCar is £968 for a Focus (2026 prices).
The gap between those figures is mostly oil-system cleaning: once belt debris is in the sump, hours are added to the bill.
Ford wet belt cost by model
| Model | Typical price | Source |
|---|---|---|
| Ford Focus 1.0 (independent, belt only) | £458–£524 | ClickMechanic |
| Ford Focus 1.0 (franchise dealer) | £750–£851 | ClickMechanic |
| Ford Focus (marketplace average) | £968 | FixMyCar |
| Ford Fiesta (marketplace average) | £938 | FixMyCar |
| Ford Transit Custom (marketplace average) | £1,054 | FixMyCar |
| Ford B-MAX (real quoted job, 2018 car) | up to £2,000 | Honest John |
Why do the ClickMechanic estimates and the FixMyCar averages differ so much? The estimates are for a straightforward belt swap. The marketplace averages include the messier real-world jobs. No published price exists for the Puma 1.0 on any of our sources, so we do not list one.
What the job actually involves
FixMyCar describes the full job as stripping the engine down, replacing the belt, cleaning the oil system to remove debris, then changing the oil and filter. On the 1.0 EcoBoost the belt drives both the camshafts and the oil pump, so any shed rubber ends up exactly where it does most harm — which is why a garage that finds debris will (rightly) quote extra hours to clean the pickup and sump. That single discovery is what separates a £500 invoice from a £1,000 one.
For perspective, a conventional dry cambelt averages £678.20 on FixMyCar — about £300 less than the Ford wet belt average from the same marketplace. The premium is all labour and access, not the belt itself.
Parts vs labour: where the money goes
The belt kit for a Focus 1.0 costs £99–£161 (ClickMechanic) — the rest is labour. ClickMechanic schedules 6–7 hours for the Focus 1.0; FixMyCar quotes 8–12 hours for wet belt jobs generally and suggests leaving the car for a day or two. At typical UK garage rates of £40–£80 per hour (Checkatrade and FixMyCar agree on this band), labour alone spans roughly £240–£960.
| Job (Ford Focus 1.0, 2013) | Independent | Franchise dealer |
|---|---|---|
| Wet belt only | £458–£524 | £750–£851 |
| Wet belt + water pump and coolant | £523–£597 | £828–£937 |
Figures from ClickMechanic’s Focus estimates. Doing the water pump at the same time adds roughly £65–£75 and saves paying the same labour twice later.
When should an EcoBoost wet belt be changed?
Ford’s official guidance, as reported by Honest John, is 10 years or 150,000 miles — but Honest John also notes specialists now strongly recommend 7–8 years or 80,000 miles, and FixMyCar advises booking a replacement once a Ford wet belt has done 80,000 miles without being changed. Owners have reported belts breaking up even with a full service history, so the cautious interval is the one to follow. The reason specialists distrust the official figure is chemistry: as engine oil ages it turns acidic and attacks the belt material, so short-trip cars with stretched service intervals age their belts faster than the mileage suggests.
What affects the price?
- Oil contamination — debris in the sump and pickup turns a 6–7 hour job into an 8–12 hour one.
- Independent vs dealer — the dealer premium on a Focus 1.0 is roughly £300 on ClickMechanic’s estimates.
- Water pump and coolant — about £65–£75 extra done together.
- Model and access — vans cost more: the Transit Custom averages £1,054 against £938 for a Fiesta on FixMyCar.
- Location — city labour rates run £50–£100 per hour against £35–£50 in smaller towns (ClickMechanic).
Frequently asked questions
Do all EcoBoost engines have a wet belt?
No. The wet belt design was used on the 1.0 EcoBoost from 2012 and on 1.5 EcoBoost engines until around the end of 2018. FixMyCar notes some newer EcoBoost engines were revised to use a timing chain instead — check your specific build year with a Ford dealer.
What happens if the wet belt fails?
Belt debris clogs the oil pickup and starves the engine of oil. Bumper reports owners pay around £5,600 on average for a replacement EcoBoost engine — several times the cost of a preventative belt change.
Should I do the water pump at the same time?
It usually makes sense: ClickMechanic prices the combined job at only £65–£75 more on a Focus 1.0, and the labour to get at both is shared.
My Ford has done 80,000 miles — is that too late?
Not necessarily too late, but FixMyCar’s advice is to book the replacement now rather than wait for Ford’s official 150,000-mile figure. Ask the garage to inspect the oil pickup for debris while they are in there.
