If your Huel US Refer a Friend code isn't applying at checkout, check these common reasons and solutions.
Before You Apply Your Code
Email verification matters: The Huel system uses the email address you enter at checkout to verify you're a first-time customer. If that email is already linked to an existing Huel account or a previous order, your Refer a Friend code won't apply — even if it's your first time ordering as an individual.
Make sure you:
Enter the correct email address at checkout (the one you want your account created with)
Proceed to the discount code field only after your email is entered and verified
Why Your Refer a Friend Code Isn't Working
1. Minimum spend not met
Your order must reach $60 before the Refer a Friend discount applies. Check your basket total and add more Huel products if needed.
2. You're not a new customer
Refer a Friend codes are for first-time Huel US customers only. If your email address is already linked to an existing Huel account or you've placed a previous order, the code won't apply. The system checks your email at checkout to verify you're eligible.
3. Another discount code already applied
Only one discount code can be used per order. Remove any other code you've applied and try your Refer a Friend code again.
4. Typo or spacing error
Remove the code and re-enter it carefully. Check for extra spaces before or after the code — spacing errors prevent the code from working.
