Tesco ranks fourth at 73.82 in WCRC’s UK 100. Sainsbury’s ranks 33rd at 66.44. Tesco’s published UK entry carries forward its global Power Score, so the positions establish where each appears in the UK table. A UK-only comparison of the shopping experience needs evidence collected on the same terms.
The Product, Innovation & Delivery pillar offers a starting point. Give the same weekly basket to both stores in the same area and week. Record which items shoppers can buy, which substitutions they accept, and the total price after applying comparable loyalty terms. For delivery orders, compare the same time windows and include charges and minimum basket values.
Run the test again when shoppers are under more pressure, such as a bank holiday weekend. A retailer can have a good experience on a quiet weekday and lose customers when everyday items run out at busy times. Repeating the basket shows where the service holds up and where the stores differ. That would answer a narrower question than the overall ranking, which assesses each brand across five pillars.
