Overview of mid-term adjustment (MTA) fees
If you need to make a change to your policy after it has started—such as updating your address, vehicle, or adding a driver—this is known as a mid-term adjustment (MTA).
Depending on the type of policy you have with Marshmallow, you may need to pay an admin fee:
Policy type | MTA fee |
Lightest | £25 |
Essential | £25 |
Original | £0 |
Plus | £0 |
The fee is automatically included in your updated premium and will be spread across your monthly payments if you pay in instalments.
How changes affect your premium
Any change to your policy details will result in a recalculation of your insurance premium. This means:
Your price may go up (e.g. if you move to a higher-risk postcode or add a less experienced driver).
Or it may go down (e.g. if you remove a driver or reduce your mileage).
Name, phone and email address changes do not impact your premium or have a fee.
Is the MTA fee ever waived?
In some cases, the £25 MTA fee may be waived. This depends on your circumstances and must be assessed by our team.
