Frequently Asked Questions
How long will my delivery take and how much does it cost?
Orders placed before 2:00 PM (UK time) are dispatched the same working day. Standard delivery to mainland Great Britain takes 2-5 days at a flat rate of £3.50, or free on orders over £10.
Large tubs are automatically upgraded to DPD next-day delivery. Shipping to Northern Ireland, the Channel Islands, and the Scottish Highlands costs £4.50, or free on orders over £80.
Can I change or cancel my order after placing it?
Because we process and dispatch orders quickly, we are usually unable to modify products, delivery methods, or addresses after submission.
To cancel an order, you must contact us on the same calendar day it was placed. If dispatch has already occurred, you can return the unused items within 14 days at your own shipping expense.
What is your returns policy if I change my mind?
You have 14 days from the day after delivery to cancel your order. Items must be unused, in their original packaging, and in resaleable condition.
Important Step: You must email from our contact us at the bottom of our Home page first to obtain a Returns Authorisation Number and a free Royal Mail returns sticker; unauthorised returns cannot be processed.
Note that opened, sealed supplements cannot be returned for hygiene reasons.
What should I do if my order is damaged, faulty, or incorrect?
Check your parcel immediately upon arrival. If there is an issue, notify us within 48 hours of delivery via our contact us section at the bottom of our Home Page.
Please include your order number, a description of the issue, and photos of the damaged items and packaging. We will provide a free replacement or full refund.
How long do refunds take to process?
Once your return is received, inspected, and approved, we process refunds back to your original payment method (card, PayPal, or bank transfer).
This typically takes place within 7 working days, and always within a maximum window of 30 days.
Are Hammer Nutrition products safe for drug-tested athletes?
Yes. Key products within our range—including Endurolytes (4ct/120ct), Endurolytes Extreme (3ct/120ct), Endurolytes Extreme Powder, and Endurolytes Fizz—are officially Informed Sport certified.
Additionally, our products are manufactured in strict ISO, GMP-compliant, and SQF Level 3 Certified facilities to ensure the highest standards of food safety and purity.
What do you use to flavour your sports nutrition products?
We use only premium ingredients with zero artificial flavours, artificial sweeteners, or chemical colorants.
Our natural flavours are extracted from real food sources (such as fruits, essential oils, and botanicals) in full compliance with FDA regulations.
They are entirely derived from non-allergenic materials and are formulated for a clean, subtle, non-sweet taste.
What should I do if my order has not arrived?
Estimated transit times are 2–5 days. If your parcel has not arrived within 5 days of placing your order, notify us immediately via the contact us at the bottom of our Home Page.
We will launch an investigation with the carrier and provide updates or arrange a replacement where appropriate.
Do you accept backorders for out-of-stock items?
No, we do not accept backorders. If an item is currently unavailable, you can enter your email address in the "email me when back in stock" widget directly on the product page to receive an automated real-time notification the moment inventory is replenished.
Are your supplements suitable for specific dietary restrictions?
Our clean sports nutrition range is formulated to support optimal body function and is completely free from gluten, artificial preservatives, and artificial colorants.
If you have specific medical conditions or severe allergen concerns, we recommend checking the explicit ingredient panels or consulting a healthcare professional prior to consumption.
