Heathrow is the UK’s busiest hub — and airport bureau convenience rarely matches online value. Treat terminal exchange desks as emergency top-up, not your main holiday budget.
Read the airport guide first
Our Heathrow airport guide covers terminals, transport and the general travel-money message for flyers. Use it alongside this article — not instead of comparing providers.
Compare before you travel to the airport
Run our holiday money comparison for your currency — euros, US dollars, UAE dirhams and others — and order with time for delivery or collection.
Long-haul vs short-haul cash needs
US and Gulf routes may need USD or AED; Europe often EUR. Match cash to tipping, taxis and small shops; put hotels and car hire on a low-fee card where possible.
Reduce airport stress elsewhere
Sort parking or lounges early — one less reason to arrive so late that you accept a poor walk-up rate.
