Starter Motor Replacement Cost UK
A starter motor replacement at a UK independent garage typically costs £250 to £450 fitted. The part is £100 to £250 for most cars, with the rest in labour that varies hugely depending on whether the starter is on top of the gearbox in plain view or buried under the intake manifold.
What it costs
| Job | Typical price (independent) |
|---|---|
| Starter motor, easy access | £250 to £320 |
| Starter motor, average access | £300 to £400 |
| Starter motor, buried (intake or subframe off) | £380 to £450 plus |
| Stop-start reinforced starter | add £50 to £100 on the part |
Cars with stop-start systems use heavier-duty starters that cost more as parts, so do not compare a quote for one of those against prices for an older car.
Symptoms
The classic sign is a single loud click when you turn the key with nothing else happening, while the dash lights stay bright. Other symptoms include a starter that spins without turning the engine, a horrible grinding on start-up, or an intermittent no-start that comes and goes with temperature. Intermittent faults often get worse in cold, damp weather, which is why starters fail in UK winters more than any other time.
Why it fails
Inside the starter, the brushes wear down, the solenoid contacts burn, and the one-way clutch on the drive gear wears out. Heat from the exhaust cooks starters mounted nearby, and stop-start systems multiply the number of starts a motor performs in its life many times over. Oil leaking down onto the starter from above is another common killer worth fixing at the same time.
Can you drive with it?
Once the engine is running the starter does nothing, so the car drives normally. The risk is being stranded, because an intermittent starter always fails at the worst moment, in a car park, at the fuel pump, on a driveway blocking someone in. Bump-starting only works on manuals and is a get-you-home trick, not a plan. Book it in promptly.
How to avoid overpaying
Insist on a proper diagnosis before anyone fits a starter. A tired battery, corroded battery terminals or a bad earth strap produce identical symptoms and cost a fraction to fix. A garage should do a voltage drop test on the starter circuit, which takes ten minutes, before condemning the motor. If your car is older and the starter is easy to reach, ask about a quality reconditioned unit, which can knock £50 to £100 off the parts price with a warranty.
Common questions
How do I know it is the starter and not the battery?
If the dash lights are bright, the headlights do not dim when you turn the key, and you hear one solid click, it points to the starter or its wiring. Dim lights and rapid clicking point to the battery. A garage can confirm in minutes.
Can a starter motor be repaired?
Sometimes, brushes and solenoids are replaceable, but at UK labour rates a reconditioned or new unit is usually cheaper than a rebuild. Recon units from reputable suppliers come with a warranty.
Does stop-start wear out the starter faster?
Stop-start cars use starters designed for far more cycles, but they still wear, and they cost more to replace. If your stop-start stops working, have it looked at rather than ignoring it, as it can be an early warning.
