If you're looking for the best whey protein in Britain, I'd compare products on protein per serving, taste, price per 100g of protein, ingredient quality and how well they mix - rather than simply choosing the biggest tub or most expensive brand.
For most people in the UK, a good starting point is a whey concentrate for everyday value, or whey isolate if you want less lactose and typically less fat and carbohydrate.
