How much does a starter motor replacement cost?

The cost of replacing a starter motor in the UK can range from £300 to £500 depending on the make and model of the car. 

This variation is mainly due to differences in parts pricing, labour time, and how accessible the starter motor is within the engine bay. 

Prices can also sit lower for smaller, more common vehicles, while premium brands or more complex engine layouts tend to push costs toward the higher end of the range.

Can a starter motor be repaired or does it need replacing?

In some cases, a starter motor can be repaired, but this depends on the nature of the fault.

Minor issues such as worn brushes, corroded connections, or faulty wiring can sometimes be fixed without replacing the entire unit.

However, in most modern vehicles, starter motors are replaced rather than repaired because:

• Labour costs for dismantling are similar either way

• Internal components are often sealed or difficult to access

• Replacement is usually more reliable long-term

This means the majority of starter motor issues end up requiring a full replacement, which is why understanding the typical cost range is important when planning a repair.

Why is starter motor replacement so expensive?

Starter motor replacement can feel expensive because it involves both parts and labour-intensive work.

The main cost drivers are:

• Labour time to access the starter motor (often buried in the engine bay)

• Vehicle make and model complexity

• Part quality and brand differences

Even though the starter motor itself may not be extremely expensive, the labour required to remove surrounding components is what pushes the total cost into the £300 – £500 range for most UK vehicles.

What does a starter motor do?

Starter motors power the combustion engine. They are like the electric motors that turn your engine on when you switch the ignition.

The starter motor requires a lot of torque to turn the engine at such fast speeds, pulling fuel and air into the cylinders to compress them simultaneously.

The starter is found on the driver's side of the engine. Typically, it's just beneath the left bank of cylinders.

How do you know if your starter motor has gone?

There are a few key signs your starter motor has gone.

If your car won't start and you hear a clicking sound when trying to turn it on, the most likely cause of this is a dead starter motor.

In addition to hearing a clicking noise, you might smell something burning from under the hood. This is typically caused by an electrical short in the starter motor, which can be due to wear and tear over time.

Here’s a complete list of signs your starter motor has broken:

• Something sounds off (e.g. a clicking sound or a whirring noise)

• Your dashboard lights work but you don’t have any engine power

• Your engine doesn’t work after a jumpstart

• There’s smoke or a burning smell coming from your engine

Replacing the starter motor will usually solve these issues, but it comes at a cost, so make sure you know how much it may cost before committing to any repairs.

What causes starter motor problems?

Common starter motor problems are caused by age and faulty parts. Here’s a quick overview of other possible causes:

• Loose wiring around the starter motor

• Corroded connections around the starter

• Aged or worn-out parts of the starter

• Oil leaks around the starter system

• Bad relay

If you suspect your vehicle has any of these issues, consult a garage for professional advice.

How long does a starter motor last?

The average lifespan of a starter motor is around 5 years or 50,000 miles. However, this can vary depending on how well-maintained your car is and how much wear and tear your starter motor experiences.

Can you extend your starter motor’s life?

Yes, you can and should check and maintain your starter motor. This keeps you safe while on the road and protects your finances from surprise repair costs.

To extend the life of your starter motor, you can:

• Ensure that your car’s battery is regularly checked and maintained

• Repair any worn or damaged components ASAP

• Avoid overloading the starter by turning off unnecessary lights or A/C functions

• Park in sheltered areas (e.g. garages) to protect your car from extreme weather and temperatures

• Warm up the engine in colder weather to reduce stress on the battery

Can you jump start a car with a faulty starter motor?

A jump start can help if your car won’t start due to a weak or flat battery, but it won’t fix a faulty starter motor. 

Both issues can result in the engine failing to turn over, but if the starter motor is the problem, you may still hear a clicking sound or nothing at all when you try to start the car, even after jump starting. 

In this case, the issue isn’t power supply from the battery, but the starter motor’s inability to engage the engine.

Pro Tip: If your car starts after a jump start, the battery is more likely the issue. If it still refuses to start, the starter motor could be at fault.

Starter motor vs battery problems: How to tell the difference

Starter motor and battery issues often produce very similar symptoms, which is why they are frequently confused.

A battery problem usually shows up as:

• Dim or flickering dashboard lights

• Slow engine cranking

• The car starting after a jump start

A starter motor issue, on the other hand, often includes:

• A single click or repeated clicking when turning the key

• No engine turnover at all, even with a charged battery

• Occasional starting followed by sudden failure

How long does it take a mechanic to replace a starter motor?

On average, it takes a mechanic around 2 hours to replace a starter motor. This time may differ depending on the garage and your car model.

How is a car starter motor repaired?

To access the starter motor, components like the battery, alternator, and engine covers often need to be removed, which can take time depending on the vehicle layout. 

Once exposed, the faulty starter can be replaced and the new unit connected to the wiring system and secured in place.

After installation, a final check of surrounding components is recommended to ensure everything is working correctly and no related parts have been affected.

What happens if you ignore a faulty starter motor?

Ignoring a faulty starter motor will not affect your car while it is running, but it will eventually lead to starting failure at the worst possible time.

Over time, symptoms usually become more frequent until the car fails to start completely and requires emergency repairs.

In some cases, continued attempts to start the vehicle can also place extra strain on the battery and electrical system, potentially increasing overall repair costs.

For this reason, Bumper urges readers to address starter motor issues early rather than waiting for a complete failure.

Can you replace a starter motor yourself?

While it is technically possible to replace a starter motor yourself, it is generally not recommended unless you have strong mechanical experience.

Mistakes can lead to further damage or incorrect installation, which may prevent the car from starting at all. If in doubt, call a mechanic!

Does insurance cover starter motor replacement?

In most cases, standard car insurance does not cover starter motor replacement, as it is considered a mechanical wear-and-tear issue rather than accidental damage.

However, it may be covered if:

• The failure is caused by a specific insured event (e.g. fire or flood damage)

• You have a separate mechanical breakdown cover policy

Some breakdown or extended warranty products may include starter motor faults, so it’s worth checking your specific policy details before getting in contact with a garage.

Is it safe to drive with a faulty starter motor?

Once a vehicle is running, you don’t rely on the starter motor, so there’s usually no immediate danger if it fails while driving. 

However, once you stop, you may struggle to restart the engine because starting requires more power than normal operation.

We don’t recommend relying on workarounds like bump-starting or parking on slopes. A faulty starter motor should always be properly repaired or replaced to ensure reliable starting.

Replacing a starter motor can be expensive, but with regular maintenance, you can extend its life and reduce the need for costly repairs.
