Why should I choose a battery replacement service?

Buying a new car battery and replacing your old one isn’t always straightforward. You need to find the right battery for your vehicle. And when fitting it, most modern car manufacturers need the battery to be coded to their system.

It takes the hassle away when you choose a professional service. Our mobile mechanics will come to you, whether you’ve broken down at home on your driveway or by the side of the road. It's easy to book a time and place that suits you online.

Our mechanics carry batteries in their vans to fit most popular manufacturers like Ford, Vauxhall and BMW. We’ll fit the new battery hassle-free. And thanks to the 5 year warranty on our batteries, you can call us if you have a problem in the future.


How do I find the right battery for my car?

You can use your car registration number to find the right battery for your vehicle. Just pop your number plate into our battery finder to see options and prices upfront.

There might be several different batteries available for your car. We'll explain the difference in output and performance to help you choose.


How much does it cost?

Your battery replacement quote is based on:

  • The cost of the new battery for your vehicle, plus
  • The cost of fitting the new battery and removing the old one.

Our price for fitting the new battery and disposing of the old one depends on your membership:

  • Member with At Home cover: Free of charge
  • Member without At Home cover: £10
  • Not yet a member: £35

Give us your number plate to get a quote and the mechanic will confirm it and take payment when they arrive.

How do I know if my car needs a new battery?

If your car battery keeps going flat or can’t be jump started, it’s probably time to get a new one. A dead battery won’t hold its charge anymore, so it’ll need to be replaced. 

Unlike many local garages, our mobile mechanics can test your battery’s health at home or by the roadside. We’ll check for any underlying faults that might drain your battery or stop it charging. 

Do you fit batteries at my home?
Yes - our mobile mechanics will come to wherever you are, including if you’ve broken down at home. When you book, choose the time and the place that suits you.
What happens when I book Battery Assist?

When you book Battery Assist online, you can choose a date, time and place and we'll come to you. If you have a dead battery at home or by the side of the road, we’ll come to your rescue.

We'll check to see if your car battery needs replacing. If it does, we’ll supply and fit it for you. Our mechanics carry batteries in their vans, so we can find one that’s right for your vehicle.

Once the new battery's in, we’ll take away the old one and dispose of it in an environmentally-friendly way.

How long do car batteries last?

Car batteries usually last around 5 years, depending on how you use your car.

If you’re having trouble starting your car before the battery's 5 years old, it probably means one of these:

  • The car’s not being driven often enough to charge the battery.
  • The car's doing too many short journeys.
  • There's a vehicle fault draining the battery or affecting charging.

Battery problems after 5 years are more likely to mean:

  • The battery's getting tired and may need replacing.

Our mobile car battery fitting service will only fit new batteries that come with a 5 year warranty.
