Log in to your Marshmallow account

In your Marshmallow account, you'll be able to select 'Update my address', then enter your new address details and the date & time of your move. We'll show you how the change will impact your annual premium before processing it.‍‍


β€πŸŒŸ Β Why is it important to update my address?

‍We need to know if any of the details on your policy change. This is because your policy might be invalidated in the event of a claim if your address isn't up to date.


β€πŸŒŸ A step-by-step guide:

‍We know that moving house can be exciting yet stressful, so we've made it easier for you to update your policy directly in the Marshmallow portal 😊

  1. Login to your Marshmallow account.
  2. Select 'Edit my policy'
  3. Select 'Update my address'
  4. Search for your new address by postcode
  5. Select the date and time you'd like the change to be effective. This should be the closest date possible to your moving date.
  6. You'll be presented with a premium change. It can stay the same, increase or a decrease to your annual premium.
  7. If you're happy with your new price, you can confirm and click 'Pay now'. You'll be redirected to a secure payment page where you can pay using all major credit & debit cards.
  8. Once the payment has been processed successfully, you'll be sent a confirmation email containing your updated policy documents.

In some cases, your account will re-direct you to our friendly Customer Service team. Don’t worry, we might simply process the change manually!
