With food prices still the biggest source of budget pressure for most UK households, supermarket loyalty schemes have shifted from nice-to-have to essential. According to the Competition and Markets Authority, 97% of shoppers now belong to at least one scheme — and the difference between member and non-member prices at the tills can be startling. Here's how each major scheme works in 2026, and how to squeeze the most out of them without changing where you shop.
The heavyweight. You collect 1 point per £1 in-store and online, and each point is worth 1p off your shopping. The real value, though, is in two places: Clubcard Prices — member-only discounts across thousands of products — and partner rewards, where Tesco doubles the face value of your vouchers when you spend them with partner brands (days out, restaurants and more), so £10 of vouchers becomes £20 of spend.
A typical family shop can include 15–25 Clubcard-priced items, and regular Tesco shoppers commonly save several hundred pounds a year through member pricing alone.
You earn 1 Nectar point per £1 at Sainsbury's and Argos, plus points with partners such as eBay. Each point is worth 0.5p (1,000 points = £5). Like Tesco, the bigger win is Nectar Prices on everyday items, and the app's personalised bonus point offers — check it weekly and activate everything before you shop.
Lidl overhauled its scheme in May 2026: the old coupon system was replaced with Lidl Plus Points — you now earn 1 point per £1 spent (rounded up) on eligible purchases and choose your rewards in the app. Combined with Lidl's already-low base prices, it's one of the strongest combinations for a budget-focused shop.
Asda works differently: instead of points, you build a Cashpot — real pounds and pence earned through "missions" and star products — which converts into vouchers off your shop. It rewards engagement with the app more than raw spend, so it suits shoppers happy to tap through the missions each week.
Comparisons by consumer groups and money sites consistently put loyalty savings for a typical household at £150–£500 a year — more for big families shopping mainly at one chain. The keys are boring but effective: scan the card every single time, check the app before shopping (not after), and activate personalised offers, which are usually better than the public ones.
Member prices first (Clubcard/Nectar Prices), then app coupons, then a discounted gift card if you use one, then cashback apps on top. Stack all four and double-digit percentage savings on a weekly shop are realistic.
Genuine supermarket voucher codes exist, but they're short-lived and mostly for online grocery orders (often new-customer offers). The reliable sources are the supermarkets' own apps and email newsletters — codes on random coupon sites are frequently expired or account-specific. A good rule: if a code isn't in the retailer's own app, newsletter or a major cashback site, don't count on it working at the till.
