What should a UK garage charge for a cambelt change in 2026?

Cambelts are the job most workshops quote over the phone and a good number of those quotes lose money. The caller asks what a cambelt costs on a Focus, somebody shouts a number across the workshop, and the job lands three weeks later on a variant with a different engine, a pump behind the belt and an extra hour and a half of book time nobody priced.

This post is the arithmetic. Trade figures below are 2025 to 2026 ranges from factor pricing and published book times. Where I am estimating I will say so.

What the job actually is

A cambelt change is rarely just a belt. Priced properly it is:

• The belt itself
• The tensioner and any idler pulleys
• The water pump, on every engine where the pump is belt driven
• The auxiliary belt, because it comes off to get at the timing cover
• Coolant, and on some engines a thermostat or housing seal
• On a wet belt engine, sump gasket, oil pump chain or belt, oil and filter

Quote the belt alone and you have priced perhaps 40 percent of the parts and all of the labour risk.

Book times you can actually price from

Typical published times, independent workshop, engine in situ:

• Common transverse four-cylinder petrol: 2.5 to 4 hours
• Transverse diesel with pump behind the belt: 3.5 to 5 hours
• Engines needing the mount out and the unit lowered: 4.5 to 6 hours
• Front end into service position, or subframe down: 6 to 8 hours
• Wet belt, sump off, oil pump drive included: 6 to 9 hours

The variance inside a single model range is the trap. Two cars with the same badge on the boot can sit two hours apart on book time depending on the engine code. Price from the engine, never from the model.

Trade parts, honest ranges

• Belt kit, belt plus tensioner plus idlers, volume brands: £45 to £120
• Belt kit including water pump: £70 to £180
• Premium and performance marques: £150 to £300, occasionally more
• Coolant, two to five litres of the correct specification: £10 to £30
• Auxiliary belt: £8 to £25

Aftermarket kits from the recognised manufacturers are what most independents fit and what most customers expect at an independent price. If you are fitting genuine parts, say so on the quote and charge for it, because the customer cannot tell the difference from a number on a page.

The formula

Price the job like this, every time:

(book hours x your labour rate) + (trade parts cost x your parts multiplier) + consumables

Worked example, a common transverse petrol four-cylinder at a workshop charging £65 an hour with a 1.4 parts multiplier:

• Labour: 4.0 hours x £65 = £260
• Parts: £95 kit with pump x 1.4 = £133
• Coolant and aux belt: £28
• Total: £421

The same job at £50 an hour comes out at £361, and at that rate you are handing over four hours of a bay and a technician for £200 of labour revenue. If that feels low, it is, and the fix is the rate rather than the job. We went through where UK rates actually sit in what a UK garage should charge per hour, and the multiplier question in what to mark parts up by.

Why phone quotes go wrong

Three specific failures, all avoidable:

The engine was never confirmed. A registration gives you the engine. Look it up before a number leaves your mouth. Our free DVLA lookup will give you the basics in a few seconds, and your technical data will give you the book time from there.

The pump was left out to win the job. It reappears as an awkward conversation at handover, or as a failed pump and a ruined engine later.

The quote was verbal. No record, no scope, no parts list. When the customer remembers £380 and you remember £480, the one without the written quote loses.

Send it in writing, with the engine, the parts list, the book time and what is excluded. It takes two minutes and it ends the argument before it starts.

The wet belt question

Wet belts run inside the engine, lubricated by the oil, and they have changed this job. Several manufacturers have revised their replacement intervals downwards since the original schedules were published, and the failure mode is debris from a degrading belt blocking the oil pickup rather than a clean snap. Check the current manufacturer schedule rather than the one printed in the book when the car was new, because on these engines the interval has been a moving target.

Commercially: do not let a wet belt job be quoted off a standard cambelt price. It is a different job with sump and oil pump work in it, and the book time reflects that.

Protect yourself on the paperwork

Cambelts generate comebacks years later, usually with somebody else's work in between. Three things to record on every one:

1. The mileage and date at replacement, on the invoice and on a sticker under the bonnet
2. The parts fitted, by brand and part number
3. The next interval, by mileage and by date

The Driver and Vehicle Standards Agency publishes the current guidance for the trade, and the Institute of the Motor Industry is the reference point for technician competence if a dispute ever turns formal. The Health and Safety Executive's motor vehicle repair guidance covers the workshop side.

Where software helps

A cambelt is a job where the quote, the parts list and the record all have to survive three years and a change of owner. Autera holds the book time and parts against the job, sends the quote in writing before the car is booked in, and keeps the replacement mileage and date on the vehicle record so the next person who opens it knows exactly what was fitted and when.
