I’ve paid for my holiday arrangements. Can my travel company still request a surcharge?

Yes, as long as their booking conditions contain explicit provisions that allow them to surcharge and don't say that no increases will be made.

Surcharging refers to your travel company changing the price of your holiday after you have booked your arrangements.

They can only surcharge where costs have gone up in respect of fuel, taxes or fees, or the exchange rate relevant to costs of the services included in the holiday. If the surcharge exceeds 8% of the original holiday cost, you can either agree to pay the surcharge and continue with the holiday, accept an alternative holiday or cancel and have a refund of your monies.

Surcharges shouldn't be confused with additional charges that you may incur for changes to your booking such as amendments or additional services.

While the regulations allow for surcharging on package holidays, it’s worth being aware that often businesses choose not to apply the surcharge. So just because a company can surcharge doesn’t mean they will.
