With temperatures soaring across the UK, Wendy’s® UK is turning up the chill factor — giving everyone the chance to enjoy a free Frosty® for one day only.
Forget the sun being eclipsed — today, the sun is OUT, and Wendy’s wants to make sure the nation stays Frosty. To help beat the heat, customers across the UK can claim a free Junior Vanilla or Chocolate Frosty, with no minimum spend and no purchase required.
Available 13 August 2026 only, the offer is Wendy’s way of delivering some instant, ice-cold heatwave relief — completely on us.
How to claim your free Frosty
Getting your hands on the offer is simple:
- Download the Wendy’s UK app.
- Add a Junior Vanilla or Chocolate Frosty to your basket.
- Select the Frosty from the Everyday Saver menu — not the dedicated Frosty category.
- Enter the promotional code HEATWAVE at checkout, or use the code as displayed in the app.
- Place your order — the promotional code will remove the cost of the Frosty, making the order totally free.
So, whether you’re escaping the heat on your lunch break, cooling down after a day outside, or simply looking for an excuse to treat yourself, Wendy’s has you covered. One day. One free Frosty. Zero spend. Maximum chill.
