Alternator Repairs cost between £100 and £700 in the UK. The average is between £150 to £300 and, while refurbished car alternators are available, they don't offer that much of a saving.
After you book your visual inspection, we send you a confirmation email with a summary of your booking. We also inform the garage and they may also be in touch to confirm the appointment or to ask for extra details.
The garage will complete the inspection and then diagnose the repair you need, providing an accurate quote for the work at the same time. You may also need to book your alternator repair in with them directly as they may not have the capacity to deal with the repair on the same day.
However, you won't pay anything until after they have completed all the work. You also deal with the garage directly after the initial booking process and can change or cancel your visual inspection for free until the day of your appointment.

The alternator belt, also known as the drive belt or serpentine belt, drives several key parts of your engine. This rubber belt keeps your steering, alternator, water pump and air conditioning working properly. It also helps to improve the performance of your car by reducing friction.
To avoid it developing any problems, you should replace your alternator belt every 45,000 to 70,000 miles. The rubber can wear under excessive pressure and heat within your engine, so it's worth driving sensibly and maintaining your car. This will help the drive belt last as long as possible.
You should book an alternator belt replacement if your engine starts squeaking or chirping. This is the key indicator of an alternator belt problem. If you ignore this warning sign, your engine can overheat and potentially break down.
The average cost of an alternator belt can range anywhere from £75 - £250. While the part itself will only cost £20 - £30, it is a tricky, time-consuming repair. This means labour costs make up most of the price
Other factors that impact the cost of an alternator replacement include the make and model of your vehicle, how accessible your alternator belt is and the hourly rate of your chosen garage.
Your alternator keeps your car’s battery charged, allowing you to start your vehicle. It also powers all the onboard electrics.
A car alternator uses the drive belt to convert the mechanical energy from the crankshaft into electricity. If your alternator fails and stops charging the battery, you may struggle to keep your car moving.
That’s why you should always book a visual inspection to diagnose the extent of your alternator repair as soon as you notice a problem.
On average, an alternator replacement takes between 1-2 hours. However, this can vary depending on what make and model of vehicle you drive.
Most alternators last between 80,000 and 120,000 miles. This means yours can last 8-12 years without needing any repairs if you look after it.
To ensure your alternator lasts as long as possible, book a car service regularly to keep your car in good condition. This avoids putting unnecessary stress on your alternator.
Your alternator is a very durable component, but it may occasionally need replacing. Common alternator problems include:
You can solve most of these problems with an alternator replacement rather than trying to repair a specific part. However, a technician will be able to give you their suggested fix after the initial inspection.
Yes, you can fit a new alternator yourself. However, you should not attempt the process unless you are experienced and know what you are doing. Not only can you cause extra damage to your vehicle, but a live battery can also be very dangerous if you don’t disconnect it properly.
To fit a new alternator yourself, you must follow this process:
You should book an alternator repair near you if you notice any of the following warning signs:
Alternator reconditioning involves repairing a part-worn alternator to create a cost-effective replacement. A specialist changes faulty parts and services the part to ensure it is in top condition.
As such, a reconditioned alternator may help you save on your replacement costs. Make sure that you buy the part from a reputable dealer and ensure it has passed all the necessary tests and checks before getting it fitted to your car. This will mitigate most of the risk.
Yes, a warranty will cover any mechanical alternator fault as it isn't considered standard maintenance. The only exception is if your alternator was damaged during an accident or through neglect.
We would recommend checking the terms and conditions of your warranty to ensure you're covered before making a claim.
You don't always need to replace your car's battery and alternator together. The battery may still be in good condition and is only hampered by a faulty alternator.
If you're concerned about the quality of your battery and alternator, we recommend booking a free visual inspection at a garage near you.
No, a faulty alternator will not cause an MOT failure. It isn't checked during the test so you're unlikely to learn about an alternator problem during an MOT appointment.
You may be able to drive your car with a faulty or broken alternator but it won't last very long. Eventually, the battery will drain and your car will grind to a halt. If you suspect your alternator is faulty or broken, we recommend contacting your recovery provider to tow your vehicle to a local garage for an inspection.
