No UK supermarket gives NHS staff a discount at the till simply for working in the NHS. The real savings come from Blue Light Card, mostly through supermarket Shopping Cards sold below face value, together with each chain’s own loyalty prices, which are open to every shopper and still apply when paying with a card.
Shopping Card Rates
M&S cards have been sold at 6% off and work in store and online. Tesco cards are 4% off but in store only, Sainsbury’s cards are 4% off in store and online with a separate code for online orders, and Iceland cards are 4% off in store with their own online code. Asda and Morrisons cards are 3.5% off, with Morrisons in store only, and Waitrose cards 3% off. The cards generally cannot be used on petrol, prescriptions, tobacco, lottery tickets, stamps, PayPoint products, gift cards, top-ups and in-store concessions.
Asda’s Cashback Has Ended
Asda used to pay Blue Light Card holders cashback into their Asda Rewards Cashpot on fresh food, but that partnership ended on 27 May 2025, so the 3.5% Shopping Card is now the only member saving there.
Loyalty Prices Still Apply
Clubcard Prices at Tesco, Nectar Prices at Sainsbury’s and Sparks offers at M&S all apply as normal when a Shopping Card is used to pay, and Tesco and Sainsbury’s both run Aldi Price Match schemes on selected products. On a £100 weekly shop, a 4% card on top of loyalty prices saves about £200 over a year.
The Discounters
Aldi and Lidl have no Blue Light Card arrangement, relying on low everyday prices and, at Lidl, the Lidl Plus app.
Non-food shopping in the Sainsbury’s group is covered on the Argos page, and every other category is on the NHS Discounts hub.
