For Marshmallow Car Insurance we may charge a fee for updating or cancelling your policy, or sending out documents in the post.

Fees for changing your policy

If you need to make a change to your policy after you’ve bought it, such as updating your address, vehicle, or adding a driver, this is known as a mid-term adjustment (MTA). This includes changes made before your policy starts.

Depending on the type of policy you have with Marshmallow, you may need to pay an admin fee:

• Marshmallow Lightest, Essential or Move: £25 fee
• Marshmallow Original or Plus: No fee

As well as a fee, changing your details can also affect your premium, so your insurance cost could go up or down.

Cancellation fees explained

Most cancellations with Marshmallow incur a fee, but how much you pay depends on when you cancel and why you're cancelling.

If you cancel within 14 days of buying

• £30 administration fee
• £45 administration fee for Marshmallow Move plans

If you cancel after 14 days

If your policy started on or after 20 August 2025, the cancellation fee is £75 (£90 for Marshmallow Move plans). For older policies, the fee ranges from £60 to £125, depending on when you bought your policy and the plan you selected.

To find the exact fee that applies to your policy:

• Open the Marshmallow app.
• Go to the Documents section.
• Select your Policy Wording document.

If Marshmallow needs to cancel your policy (e.g. due to unpaid instalments or inaccurate information being provided), a cancellation fee of up to £130 may apply.

Missed payment fee

If you miss a monthly payment, a £22.50 missed payment fee may apply. The fee is raised when your payment fails and is separate from your outstanding premium. It does not change your overall policy price.

Documents postage fee

You can access your documents at any time in the Marshmallow app. But, if you would still like to receive your policy documents by post, we can arrange this for you. There’s a £10 postage fee to cover the cost.
