Cheapest Supermarkets in the UK: 2026 Price Comparison

SYM

Where you shop matters as much as what you buy. The difference between the cheapest and most expensive supermarket can be £30-50 per weekly shop — that's over £1,500 a year. Here's the definitive ranking to help you alongside our grocery saving tips.

The 2026 Supermarket Price Rankings

Based on price tracking data and consumer research, here's how UK supermarkets rank from cheapest to most expensive for a typical weekly shop:
  • •1. Aldi — Consistently the cheapest, averaging 15-20% less than the Big Four
  • •2. Lidl — Neck and neck with Aldi, occasionally cheaper on specific items
  • •3. Asda — The cheapest of the Big Four, with strong own-brand range
  • •4. Tesco — Competitive with Clubcard Prices (up to 50% off selected items)
  • •5. Sainsbury's — Mid-range, but Nectar Prices offer targeted savings
  • •6. Morrisons — Generally the priciest of the Big Four
  • •7. Waitrose — Premium pricing, though myWaitrose offers some perks
  • •8. M&S — Most expensive for a full shop, but quality-focused

The Loyalty Card Factor

Loyalty schemes have dramatically changed the picture. Tesco Clubcard Prices and Sainsbury's Nectar Prices mean non-members pay significantly more. If you shop at these stores, always use your card. However, be aware that 'savings' shown are often vs inflated non-member prices rather than genuine discounts.

Own-Brand vs Branded Products

The biggest savings come from switching to own-brand products. Aldi's and Lidl's entire model is built on own-brand equivalents that are often made in the same factories as premium brands. Across all supermarkets, own-brand basics (value ranges) are 40-60% cheaper than branded equivalents. Start with items where brand loyalty is weakest — tinned goods, pasta, rice, cleaning products.

Online Shopping and Delivery

  • •Aldi and Lidl: Limited online grocery delivery; mainly click-and-collect
  • •Tesco: Delivery from £2.49, or Delivery Saver from £3.99/month for unlimited
  • •Asda: Delivery from £1, with regular free delivery promotions
  • •Amazon Fresh: Competitive prices, free delivery for Prime members over £40
  • •Ocado: Premium prices but excellent service and substitution policy
  • •Iceland: Free delivery over £40, great for frozen food bargains

Frequently Asked Questions

Is it worth travelling further to shop at Aldi or Lidl?+

If the extra journey costs less than £5 in fuel, probably yes — the typical saving on a full weekly shop is £15-30 compared to Tesco or Sainsbury's.

Are supermarket own brands as good as branded products?+

In blind taste tests, own brands frequently match or beat branded equivalents. Start with low-risk items and work your way up to see what works for your family.

What about shopping at multiple supermarkets?+

Some people cherry-pick deals from different stores, but the time and fuel costs often outweigh the savings. Pick one main cheap store and supplement with deals from others.
