When should I update my registration plate?
If you’ve recently added a personalised plate or changed your registration plate with the DVLA (Driver and Vehicle Licensing Agency), it’s important to update this information in your Marshmallow app. This ensures your insurance details stay accurate and valid.
Important: This change updates the registration plate only. If you've bought a new vehicle, you'll need to complete a separate update to change the vehicle on your policy.
How to update your registration plate in the Marshmallow app
You can make this change yourself in just a few steps:
Open the Marshmallow app and log into your account.
Tap ‘Your policy’ from the home screen.
Select ‘Manage policy’.
Scroll to ‘Manage your vehicle’.
Choose ‘Add personalised plate’ and follow the instructions.
This will update the registration plate linked to your vehicle. You’ll receive updated policy documents in your app once the change is complete.
Will I be charged for this change?
Yes, if you're on a Marshmallow Lightest or Marshmallow Essential plan, a £25 admin fee applies for updating your registration plate—even if your premium doesn't change. This is part of our standard mid-term adjustment (MTA) process.
If you're on a Marshmallow Original or Marshmallow Plus policy, there’s no admin fee for this change.
