Five Guys is celebrating National Burger Day 2026 with a seriously tempting buy-one-get-one-free burger offer for Rewards members.
Burger fans have another reason to celebrate this National Burger Day, as Five Guys is giving Rewards members the chance to grab a free burger when they buy one on Thursday 27 August 2026.
The limited-time offer is available exclusively to members of Five Guys Rewards, with customers needing to sign up by Wednesday 26 August to receive the BOGOF voucher in their account ahead of the big day.
How to Get the Five Guys National Burger Day Deal
Getting involved is simple. Customers need to join Five Guys Rewards by Wednesday 26 August, with the National Burger Day offer then loaded into their account ready to redeem on Thursday 27 August.
The Five Guys Rewards programme works through a customer’s phone wallet, meaning there is no need to download a dedicated loyalty app. Members can add their Rewards pass to Apple Wallet or Google Wallet and access offers directly from their phone.
The offer is particularly appealing for anyone heading out for a burger with a friend, partner or family member, as the second qualifying burger is free. Five Guys’ reward terms state that its buy-one-get-one-free main-item reward applies when purchasing one qualifying main, with the cheaper qualifying item being free.
Customise Your Five Guys Burger
Of course, part of the appeal of Five Guys is the ability to build your burger exactly how you like it.
The restaurant offers 15 free toppings, giving customers more than 250,000 possible burger combinations. From a classic Cheeseburger to a fully loaded creation, you can mix and match your toppings to create something completely your own.
Five Guys also cooks its burgers to order using 100% British and Irish beef, while its hand-cut fries are prepared fresh and served with the brand’s famously generous extra scoop.
Don’t Forget the Fries and Milkshakes
If you’re making a full National Burger Day meal of it, Five Guys’ salted or Cajun fries are an obvious addition.
The brand is also known for its customisable milkshakes, with flavours and mix-ins ranging from classic favourites to options including Pistachio, Bacon and the new Jimmy’s Iced Coffee.
For anyone looking to try something different, the Jimmy’s Iced Coffee milkshake combines the flavour of iced coffee with Five Guys’ signature shake, while customers can customise their drink with additional mix-ins.
What Is Five Guys Rewards?
Five Guys Rewards launched in Great Britain in April 2026 and gives customers rewards for qualifying visits. Unlike traditional points-based loyalty schemes, rewards are loaded directly into a customer’s digital wallet.
Members can earn rewards when they make qualifying purchases in participating Five Guys restaurants, with the programme available across England, Scotland and Wales. Rewards can be redeemed in-store, at digital order points and at drive-thrus, subject to the individual offer’s terms.
The programme also includes a free fries welcome reward and birthday treats, making it worth signing up even beyond the National Burger Day promotion.
