VAT refunds

Visitors from non-European Union countries can reclaim the sales tax (VAT) on purchases from a number of British retailers.

To claim, first purchase goods from any merchant displaying the Tax Free Shopping sign. You'll be given a tax refund form by the retailer – keep it along with your receipt.

Then when you get to the airport, take your receipt and form to the Travelex counter. Your tax refund will be paid in cash.

You can even have your refund paid in your own local currency – just ask when you get to the desk.

This service is provided by Travelex. For further details, call +44 (0)8702 405 405 or visit the Travelex website.
