This Booking Changes calculator enables Group Leaders to generate their own revised invoicing for changes in group numbers. Enter your new numbers and other details, deducting any deposit paid. For groups paying in sterling, the exchange rate should also be adjusted to match that on the original invoicing. We receive a copy of your revised invoicing, and will reply very shortly to confirm with you the changes made.

Reinvoicing for student withdrawals can be made up to 8 days before arrival.
