Your alternator keeps your car’s battery charged, allowing you to start your vehicle and power your electronics. It uses your car’s drive belt to convert the mechanical energy from the crankshaft into electricity. If your alternator fails and stops charging the battery, you can struggle to keep your car moving. That’s why you should always book an alternator repair as soon as you notice a problem.
You should book an alternator repair near you if you notice any of the following warning signs:
Alternator Repairs cost between £100 and £700 in the UK. The average is between £150 to £300 and, while refurbished car alternators ar 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 give you a nasty shock if you don’t disconnect it properly.

If an alternator replacement sounds like too much hard work, enter your reg and postcode to find a garage near you to complete the work instead. You can filter by reviews, labour rate, distance or availability - whatever matters to you the most. Once you’ve compared deals and picked the most suitable garage, you can select your preferred date and time to complete the booking.
You never pay a penny until after your chosen garage has completed your alternator repairs and there are no hidden extras either. When you compare garages near you through BookMyGarage, you can save up to 70% vs booking an alternator replacement direct.
On average, an alternator replacement takes between 1-2 hours. However, this can vary depending on what make and model of vehicle you drive.

How to be a better driver
Whether you’re driving in Tavistock or further afield, think about road user etiquette. Showing respect for other road users makes driving more pleasant for you and safer for everyone. For example, if you have to make a last minute change of lane, make your request to change clear to the driver who will need to let you in - and signal your thanks if they do. Be ready to abandon the change of lane if they won’t play ball - your safety (and that of other drivers and pedestrians) is more important than getting to your destination in the shortest time possible. When the position is reversed and a driver asks your permission to change lanes, allow them to as long as it is safe. If you get frustrated, avoid using your horn - it won’t improve matters and might make them considerably worse.
