About Plant-Based Protein
Plant-based protein has come a long way. Modern vegan blends combine pea, rice, hemp and soy isolates to deliver complete amino acid profiles that rival whey - often at a lower price point.
This page shows every plant-based protein powder we track across UK retailers, ranked by cost per 25g of protein. Whether you are fully vegan, lactose intolerant, or just looking for a lighter alternative to whey, you can compare options side by side on price, protein content and macros.
Every price is shown with the date it was checked. Use the filters to narrow by brand, bag size or specific plant protein type.

Methodology
How we rank every bag.
Independent and transparent, with every price shown alongside the date it was checked. Here's what goes into each score.
01
Cost normalised to £/25g
Every bag divided by its true protein weight, so you see the real cost of a scoop across any size or brand.
02
Protein density, measured
Protein per 100g from the product's own nutrition panel, so a 90% isolate and a 72% concentrate are never compared on bag price alone.
03
Every price carries its date
Prices come from the retailer's own listing, never an RRP, and each one is shown with the day it was last checked so you can judge how current it is.
04
No sponsored placements
Rank order is cost per 25g of protein. Some outbound links earn commission; none of them buy a position in the table.
Questions, answered.
For muscle building, plant-based protein can be just as effective as whey when you choose a blend with a complete amino acid profile. Pea and rice protein together provide all essential amino acids. The main trade-off is taste and texture - plant proteins tend to be grittier and more earthy than whey.
Soy protein isolate and pea protein isolate typically deliver 80-85g of protein per 100g, which is comparable to whey concentrate. Blended plant proteins (pea + rice + hemp) usually sit around 70-75g per 100g due to the mix of sources.
Bulk's vegan protein blend and Myprotein's Vegan Protein Blend are typically among the cheapest options per 25g of protein. Use the grid above - it ranks every plant-based option by cost per 25g, with each price shown alongside the date it was checked.
