If your car has started shaking more at idle, thumping when you pull away or sending a fresh vibration through the cabin, an engine mount is one of the first things worth checking. The awkward bit is that garages do not always quote this job in the same way. One estimate may cover a single mount. Another may include a gearbox-side mount, extra labour for tight access or a recommendation to change a second tired mount at the same time.

That is why the price can look all over the place. A realistic UK answer is that engine mount replacement is usually a mid-hundreds repair, but it can land lower on simpler small-car jobs and higher on premium cars or layouts where access is poor.

The short answer

Garage.co.uk gives a typical UK guide price of £120 to £380 for engine mount replacement. YourCar says a single mount replacement often lands around £150 to £300 once parts and labour are included, while a 2026 GSF benchmark puts the job at £110 to £220 on average with labour of roughly 1 to 1.5 hours.

Taken together, that points to the same practical conclusion: many drivers will be quoted somewhere in the low to mid hundreds, but the bill can move well beyond that when the mount is hard to reach, the car uses pricier parts or more than one mount is due.

Why one garage quotes £140 and another wants more than £300

The biggest reason is that "engine mount replacement" is not always the same job. Most cars use three or four mounts, according to YourCar, and not all of them are equally easy to replace. A front upper mount on a roomy engine bay can be much simpler than a lower mount or a gearbox-side mount that needs extra support work and more dismantling.

Other factors that change the bill include:

  • How many mounts actually need changing
  • Whether the quote is for an OEM part or a cheaper aftermarket part
  • How tightly packed the engine bay is
  • Local labour rates, especially in more expensive areas
  • Whether extra deterioration has already caused collateral issues, such as stretched hoses or extra drivetrain movement

This is also why comparing quotes line by line matters. Ask whether the figure is for one mount only, whether the part is branded or pattern, and whether VAT is included.

Typical UK prices by brand

Garage.co.uk’s brand examples show how wide the spread can be even before local labour differences are added. Its current guide figures include:

Brand Guide price
Citroen £163.73
Ford £185.73
Volkswagen £190.91
Nissan £213.85
BMW £228.91
Mercedes £287.03
Audi £299.08
Toyota £311.68

These are not fixed prices for every model, but they are useful for expectation-setting. If you drive a larger premium car, or a model where access is awkward, the quote moving north of £300 should not be a shock.

Labour time: usually not huge, but access is everything

GSF’s benchmark puts labour at around 1 to 1.5 hours, while YourCar says replacing each engine mount can take 1 to 2 hours by a mechanic. That sounds manageable, and often it is. But this is one of those repairs where the layout of the car matters more than the headline average.

The mount itself may not be especially expensive. The time is what starts to hurt when the engine has to be supported carefully, surrounding parts need to move and rust or tight packaging turn a tidy job into a more fiddly one.

That is also why a cheaper quote is not automatically the better one. If one garage has priced for a single accessible mount and another has spotted that a second mount is also failing, the higher figure may simply be the more honest one.

Signs an engine mount may be failing

A worn mount usually announces itself through feel and movement rather than a warning light. The common signs pulled together from YourCar and GSF include:

  • Excessive vibration, especially at idle or under load
  • Bangs, thumps or clunks when moving off or changing gear
  • More engine movement than normal when starting the car
  • A harsher-feeling gear change
  • Visible wear, cracking or separation in the mount if inspected

Those symptoms do not prove the mount is definitely at fault. Driveshaft issues, exhaust contact, worn suspension components and other drivetrain problems can create similar noises. But if the car suddenly feels rougher through the cabin, mounts deserve a proper look.

Can an engine mount fail an MOT?

Yes. The official MOT inspection manual says an engine mounting or bracket that is severely damaged or deteriorated resulting in excessive movement is a major defect. If an engine mounting or bracket is fractured, missing or excessively loose, that is a dangerous defect.

That matters because some drivers treat mount noise as a comfort issue and keep putting it off. Once movement becomes excessive, it is no longer just about refinement. It can become an MOT problem and a safety problem. If you are already dealing with other likely test items, Motoring Mojo’s guide to common MOT repair costs is worth reading alongside this one.

Is it safe to keep driving?

For a short period, a mildly worn mount may do little more than add vibration and make the car feel less refined. But that is not a great reason to leave it for months. The mount’s job is to hold the powertrain in position and control movement. Once it stops doing that properly, the extra movement can put more stress on surrounding components.

If the car is thumping hard, rocking noticeably, or you can feel a sharp knock as the engine takes load, get it checked sooner rather than later. The longer you leave it, the more likely it is that the repair stops being a straightforward one-mount job.

What to ask before you approve the repair

A good engine mount quote should answer a few basic questions clearly:

  1. Which mount has failed?
  2. Is the quote for one mount or more than one?
  3. What brand or quality level is the replacement part?
  4. How much of the bill is labour?
  5. Is there any sign the extra movement has affected nearby parts?

Those questions matter because the phrase "engine mount replacement" sounds more standardised than it really is. Drivers often only discover that after getting two very different estimates for what appears to be the same problem.

The practical bottom line

For most UK drivers, engine mount replacement is best thought of as a mid-hundreds maintenance repair, not a tiny nuisance job and not automatically a wallet-destroyer either. The rough national guide is around £120 to £380, with many everyday cars landing somewhere in the middle.

If your quote is above that, do not panic straight away. Check whether it covers a premium model, awkward access, more than one mount or higher-quality parts. If your quote is far below it, make sure you understand exactly what is and is not included.

The smartest move is not chasing the lowest number. It is making sure you are comparing the same job.

FAQ

How many engine mounts does a car usually have?

Usually three or four, though the layout varies by model. That matters because the failed mount is not always the easiest or cheapest one to replace.

Are engine mounts and gearbox mounts the same thing?

Not exactly, but the official MOT manual specifically includes mountings bolted to the gearbox that give essential support for the engine. In day-to-day garage language, quotes can sometimes blur the distinction, so ask which mount is being priced.

Why can the part look cheap but the quote still feel high?

Because access, support work and labour time can matter more than the mount itself. A modestly priced part can still turn into a bigger bill on a tightly packaged car.

Should you replace more than one mount at once?

Not automatically. But if one has failed and another is clearly tired, replacing both can save repeat labour and stop you paying for near-identical access work twice.
