🚨Some things to remember:

  • Watch out for typos
    For example, 0 and O look similar, but we need the exact registration to insure the correct car!
  • Please ensure the make and model in our system matches your vehicle.
  • We will stop insuring your current car the moment we start insuring the new one.
    If you'd like to have both cars insured with Marshmallow, feel free to visit our website here to get a new quote for your second car.
  • We can only insure cars registered in the UK.
    We might be able to insure cars imported from another country if it's been registered in the UK.
