GAIL's Promo Code: Free Coffee or Loaf with the App

Last updated: 5 October 2026

This page contains a referral link, which is a paid link. If you sign up through it, I earn a referral reward at no extra cost to you. Brands don't choose what I feature or what I say about them.

Sign up to GAIL's with code RF4ZQDHA

How to claim the GAIL's promo code

1. Tap the button above on your phone. It opens the app download, or the sign-up screen if you already have the app installed.
2. Create your account and check the referral code field reads RF4ZQDHA. If you are typing it yourself, enter it before you finish signing up.
3. Make your first order in a bakery or through the app, and add the free drink or loaf to it.
4. Find the voucher in the Rewards section of the app and scan your app QR code at the till.

If the voucher has not appeared, GAIL's Customer Experience Team can check it for you. They will ask for your loyalty ID, which sits in the app.

What the free item can be

You choose one barista-made drink or one loaf. The drinks list covers coffee, tea, hot chocolate, matcha, chai and iced drinks. However, pre-packaged drinks, extra shots and whipped cream are excluded, so a bottled juice from the fridge will not count.

The welcome voucher cannot be combined with any other offer on the same order. Also, once it expires after two months, GAIL's will not reinstate it, so use it on your next bakery visit rather than saving it.

The GAIL's loyalty stamps

After the welcome voucher, the app keeps paying back through stamps. You get one stamp for every transaction in a bakery, online or in the app, and an extra stamp when you spend more than £20 in one go. After nine stamps, the card resets and you get a voucher for a barista-made drink or a loaf.

In a bakery, you scan the QR code on the app's home screen at the till. GAIL's says stamps can take up to 15 minutes to show. Meanwhile, online and app orders add the stamp automatically.

Ordering ahead in the app

The GAIL's Bakery app also handles same-day Click and Collect. You pick a bakery, order and pay in the app, then skip the queue when you arrive.

The app is free on the UK App Store, where it rates 4.2 out of 5 from about 1,700 ratings. It is also on Google Play. The iPhone version needs iOS 15.6 or later.

Refer your own friends

Once you are signed up, your own referral code sits in the Rewards section. When a friend joins with it and makes a purchase, you get a free loaf voucher within four hours. You can refer up to five friends a calendar month, but only one loaf voucher lands per day. The 2kg loaves are excluded, and the voucher works in GAIL's bakeries only, for two months.

Limits to know before you sign up

• Sign-up only: the code cannot be added once the account exists.
• First order only: the free item goes on your first paid order.
• Not on the website: vouchers cannot be redeemed on GAIL's web shop orders.
• Two-month expiry: expired vouchers are not reinstated.
• No stacking: it cannot be used with any other offer.

GAIL's can change the scheme, so the terms in the app on the day you sign up are the ones that apply.
