Warning for Sainsbury’s Nectar card holders: Check your app before Friday

December 18, 2025

As the festive season unfolds, many of us find ourselves indulging a bit more than usual, whether it’s treating ourselves to those extra mince pies or splurging on Christmas gifts. Amidst this indulgence, a timely reminder has emerged for frequent Sainsbury’s shoppers. The supermarket giant has issued a crucial alert for all Nectar card holders. Yes, it’s that time again when a simple check on your app could save you from potential woes.

Nectar Card Update: A Crucial Deadline Approaches

With over eighteen million members in the Nectar loyalty scheme, many individuals are unaware of recent changes that could affect their hard-earned points. This week, Sainsbury’s warned that card holders should check their apps before Friday due to an impending deadline. With the recent spate of complaints regarding points theft, Sainsbury’s has rolled out an important security update aimed at protecting your rewards and ensuring you feel your points are safe.

The Security Measure: ‘Spend Lock’ Feature Explained

One of the most significant changes is the introduction of the ‘Spend Lock’ feature. This enhancement allows users to temporarily freeze their points, which helps prevent any potential unauthorised usage. The mechanics are simple: when your points are locked, your balance will reflect as zero at checkout—both in-store and online. Just remember, if you want to use those points, you’ll need to unlock them through your app first! Quick note for card holders: only the primary account holder has the ability to lock or unlock points, so it’s crucial to keep this in mind if you’re sharing your account.

Why This Matters: Real Stories from Fellow Shoppers

Unfortunately, the necessity for this update came to light after numerous reports indicating that criminals had been exploiting vulnerabilities within the Nectar system. Many have shared unfortunate stories of losing points through fraudulent activities, only to discover it when it was too late. One notable case involved a shopper who intended to utilise their 10,000-point balance for Christmas festivities, only to learn it was spent on an extravagant bottle of cognac halfway across the country. These incidents highlight the crucial need for heightened security as well as keeping your app notifications active.
