If you saw a discount applied in your basket but it vanished or didn't apply when you reached checkout, here's what's most likely happening.
The main reason: Only one discount per order
Huel's system can only apply one discount code at a time per order. If you have:
A new customer code
A referral code
A promotional code
...we'd recommend using the one that gives you the best value, expires soonest, or can't be used on a future order, such as a new customer or referral code.
This doesn't affect our automatic subscription or large order discounts, which can still be used alongside a manually added discount code.
We offer:
10% off all products with our flexible Huel subscription service
10% off orders over £85 automatically at checkout
What's happening behind the scenes
When you browse and add items to your basket, Huel displays every discount you're eligible for. This is meant to help you see all your options.
We offer:
10% off all products with our flexible Huel subscription service
10% off orders over £85 automatically at checkout
How to check which discount applied
Once your order is confirmed:
Go to your Account on huel.com
Click Order History
Find your order and check the Discount line in your total calculation
You'll see exactly which automatic discount and/or custom discount code was used and how much you saved
What you can do
Before checkout:
If you're manually entering a code, make sure to enter it and click 'apply'
Read the code's terms — new customer codes often have a minimum basket value (usually £60+)
Check whether the code excludes certain products or bundles — even codes advertised as "off everything" may have exclusions. These will be listed in the terms of the email you received.
If you have a choice between multiple codes, we'd recommend using the one that gives you the best value, expires soonest, or can't be used on a future order, such as a new customer or referral code.
If your discount didn't apply:
Double-check you're eligible (new customer codes only work on first orders, referral codes require account setup, etc.)
Verify the code is still valid — some codes expire
Make sure your basket meets the minimum spend requirement
Check whether your basket contains bundles or specific products that may be excluded from the promotion
