Your car’s alternator has a vital role to play in your car’s electrical system, recharging your battery as you drive and powering other key components like the headlights and air conditioning.

During an alternator repair, a technician will inspect the faulty part and repair or replace any necessary components to get it working properly again.

 

When Should I Book an Alternator Repair?

  • Dimming or flickering headlights or interior lights

  • Difficulty starting the car

  • Unusual whining, grinding or squealing noises from the engine bay

  • Electrical issues, such as slow-moving windows, radio or infotainment systems cutting out or poor performance from the air con system

 

You should act quickly if you notice any of these issues. Once the alternator can no longer keep the battery charged because the car will only continue running until the battery is depleted – which can happen at very short notice.

Frequently asked questions

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.
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.
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.
Many garages offer same- and next-day appointments, so you can book a repair even at short notice.
If your car can’t be driven, you can book a mobile repair and have the work carried out on your driveway.
12-month parts and labour warranties are often available at many garages, with any awards and accreditations displayed too.
We award certain garages on our site with Tier badges. These Silver, Gold and Top tier badges show that the garage has met and maintained strict criteria that proves they provide a truly quality service.
We only work with garages that we know can deliver on quality, and any garages that don’t meet our high standards are removed from the site.
Certain repairs on our site are not on our list of instant price products yet. In the meantime, you can compare labour rates from garages near you to find a good deal. Labour rates make up most of the final cost, so opting for a lower-cost option can help you keep the price of your repair down.
Labour rates are what a garage charges for an hour of their time, excluding parts costs and VAT. We show labour rates when you’re searching for a general repair because most of any quote pays for the technician’s time, whilst parts can be quite cheap in comparison. Prices also greatly vary depending on the repair your vehicle needs.
A professional alternator replacement can take between 1 and 2 hours. As an alternator repair is a specialist job, it takes longer – so it can be more cost-effective to have the alternator replaced instead of repaired.
A healthy car battery helps the alternator run, whilst battery issues can make the alternator wear out faster. If the battery is new and holding a charge, replacing it may not be required. If the battery has been damaged by the alternator, though, it will need to be replaced at the same time as the alternator.
Driving with a bad alternator can cause damage to vital electrical components, so you should avoid driving until you’ve had the problem fixed.
If your alternator is broken, this will cause problems with the electrical system, so it’s important that you address the issue quickly by booking an appointment at a skilled garage.
Alternator reconditioning is a process of restoring a faulty or worn-out alternator by replacing the worn individual parts. In general, having a new alternator replaced can mean the part lasts longer.
