How to Book a Visual Inspection For Your Alternator Repair

  1. Enter your vehicle reg and postcode.
  2. Compare deals. You can sort garages in your area by whatever best suits your needs: labour rate, distance, reviews and ratings or availability.
  3. Pick a date and time for your appointment.


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 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.

How Much Does an Alternator Cost in the UK?

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.


Can I Fit a New Alternator Myself?

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:

  1. Disconnect the battery. You must disconnect the terminals in the right order and ensure it is completely disconnected before continuing.
  2. Disconnect the wires from the back of the alternator. Label the wires as you go so you can reconnect them all in the right place.
  3. Remove the belt from the pulley.
  4. Remove the bolts. These connect the alternator to the bracket. Once these are loose, you are then able to get the old alternator out of the car.
  5. Make sure you have the correct replacement alternator. The last thing you need is a part that's too big or too small.
  6. Reverse the removal steps to install the new alternator.


Alternator Belt Replacement

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.

How Much Does an Alternator Belt Replacement Cost?

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.
