Cheapest Protein Powder UK — Best Value Ranked by Price Per 100g
This page ranks every protein powder we track by the single metric that matters most: how much it costs to get 25g of protein. No marketing spin, no inflated RRPs — just the actual price you pay per serving of protein, normalised across different bag sizes, brands and retailers.
We include whey concentrate, whey isolate, casein, vegan and plant-based products. The cheapest option across all types floats to the top. Use the filters to narrow by category, brand or size if you already know what type you want.
Prices are checked weekly across UK retailers including Myprotein, Bulk, Amazon UK, Holland & Barrett, Protein Works and more. If a product is out of stock it is hidden by default — toggle the filter to see everything.

Frequently Asked Questions
What is the cheapest protein powder in the UK right now?
It changes weekly depending on sales and discount codes. The table above is sorted by cost per 25g of protein in real time — the product at the top is currently the cheapest across all UK retailers we track.
How is cost per 25g protein calculated?
We take the price of the product, divide by the total grams in the bag, then multiply by how many grams you need to get 25g of actual protein (based on the product's protein percentage). This gives a fair comparison regardless of bag size or serving suggestion.
Is the cheapest protein powder good quality?
Price and quality are not always correlated. The cheapest options are typically whey concentrate from large UK brands like Myprotein or Bulk — these are well-established products with consistent quality. Extremely cheap unfamiliar brands may be worth checking the protein content per 100g before buying.
