| Compare | Sainsbury's | Tesco |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | UK weekly grocery shops | UK weekly grocery shops |
| Who it's not for | Shoppers expecting the cheapest basket . Tesco beat its price-match scheme | Anyone outside UK/Ireland delivery zones |
| Privacy | No public vulnerabilities in.uk itself; 2025 incidents touched the loyalty scheme and a shared supplier.⁶ | Multiple historical incidents (2014, 2016, 2021); no new breach evidence in the sources reviewed. |
| Support quality | 3.6/5 Trustpilot; complaint threads dominate reviews | Only review counts found, no service detail |
| Public sentiment | Mixed at 3.6/5 on Trustpilot, with online substitutions, price creep, and billing discrepancies dominating negative reviews.¹ | Shoppers value the range and delivery convenience but repeatedly complain that prices feel volatile, rising, and Clubcard-dependent. |
| Biggest gotcha | Substitutions arrive wrong or overpriced; you must manually check the substitution price promise.⁴ | Breach history: Tesco Bank 2016, Clubcard accounts, 2021 hack attempt |
