Auto electrical services in Cornwall: Car owners vs leasers

If you own the car:

You’re responsible for maintaining your vehicle, including sorting any electrical problems. Whether you drive an older car or something newer, hiring a mobile auto electrician in Cornwall is often quicker and easier than booking into a garage, especially if your car won’t start.

If you lease the car:

It depends on your lease agreement. You’re usually responsible for basic upkeep and repairs that aren't covered by warranty or maintenance packages. If you notice an electrical issue, contact your leasing provider before booking a repair. Some may require you to use approved garages.
