Yes, you can nominate a trusted person such as a family member, friend, or partner to assist with managing your Marshmallow car insurance policy. This is known as adding a Third Party Authority (TPA) or nominee.

Adding a nominee means they can speak to Marshmallow on your behalf and request changes to your policy, within set limits.

What can my nominee do?

Once a nominee has been added and verified, they can use live chat to request mid-term adjustments (MTAs), such as:

  • Changing the insured vehicle
  • Updating your address or mileage
  • Adding a private registration plate
  • Ask general questions and discuss the policy with Marshmallow

They can also help with day-to-day policy management if you’re unavailable or need extra support

What can’t my nominee do?

Your nominee cannot:

  • Cancel your policy without your explicit permission
  • Change the email address on the policy
  • Authorise any change that increases your premium by more than £200 without your consent

For any adjustments above £200, our team will contact you directly to confirm before proceeding.

How do I add a nominee?

To nominate someone:

  • Contact our Customer Support team and let them know you’d like to add a nominee.
  • We’ll ask for both your and your nominee’s full details (including names, dates of birth, postcodes, and contact numbers).
  • We’ll then contact your nominee to confirm their consent.
  • Once verified, we’ll confirm with you and update your profile accordingly.

You can revoke this access at any time by contacting us.

How is a nominee verified?

When your nominee contacts Marshmallow, we’ll ask them to confirm:

  • Your name
  • Policy number
  • Date of birth
  • Postcode

We’ll also verify the nominee’s:

  • Full name
  • Date of birth
  • Postcode
  • Last 3 digits of their contact number

If they can’t provide this information, we won’t proceed with the conversation for security reasons.
