Groceries are the second-biggest expense for most UK households after housing. According to the ONS, the average UK family spends over £60 per week on food and drink — that's more than £3,100 a year. The good news? With a few smart habits, you can realistically cut 20–30% off your grocery bill without eating worse. Here's how to save money on groceries in 2026, with strategies that actually work for UK shoppers.
Start With a Meal Plan (Even a Simple One)
Meal planning is the single most effective way to reduce food spending. You don't need a colour-coded spreadsheet — even a rough plan for 5 dinners saves money:
- Check what you already have in the fridge, freezer, and cupboards before shopping
- Plan meals around what's on offer at your supermarket that week
- Cook in batches — make 4 portions instead of 2 and freeze the extras
- Designate one 'use it up' meal per week where you cook with whatever's left
- Write a shopping list based on your plan and stick to it — impulse buys add up fast
Switch Supermarkets (or Mix and Match)
Brand loyalty costs money. The price gap between UK supermarkets is significant:
Aldi and Lidl are consistently 20–30% cheaper than the Big Four (Tesco, Sainsbury's, Asda, Morrisons) for a typical basket. Their own-brand products win blind taste tests regularly.
The mix-and-match strategy: Do your main shop at Aldi or Lidl for staples, then pick up specific branded items from Tesco or Sainsbury's if needed. Many families save £30–50 per week just by switching their main shop.
Don't overlook farmfoods and Iceland for frozen vegetables, which are just as nutritious as fresh and last much longer — reducing waste and saving money.
Use Cashback and Loyalty Apps
In 2026, there are more ways than ever to earn money back on groceries:
- Tesco Clubcard: Essential for Clubcard Prices — some items are 50% cheaper with the card. Collect points for vouchers or boost them with Reward Partners
- Sainsbury's Nectar: Personalised pricing through the SmartShop app gives genuine discounts on items you buy regularly
- Lidl Plus: Weekly scratch cards, digital coupons, and the monthly reward — small savings that compound
- Too Good To Go: Magic bags from supermarkets, bakeries, and cafes for £3–4 containing £10+ worth of food
- Shopmium: Cashback on specific branded products — scan your receipt and get money back via PayPal
- CheckoutSmart: Similar to Shopmium — browse offers before you shop and claim cashback afterwards
Master Reduced-to-Clear Shopping
Every UK supermarket reduces items approaching their use-by date. Learning the markdown times at your local stores can unlock massive savings:
Typical markdown schedules:
• Tesco: First reductions around 3–4 PM, final markdowns from 7 PM
• Sainsbury's: Varies by store, but 5–7 PM is common for final reductions
• Morrisons: Often reduces in the morning and again from 6 PM
• M&S Food: 30 minutes before closing for the deepest discounts
Tips for yellow sticker shopping:
• Check the yellow sticker shopping guide for detailed strategies
• Bring a cool bag — buy reduced meat and freeze it immediately when you get home
• Don't buy something just because it's reduced. Only grab it if you'd eat it anyway
• Reduced bread freezes perfectly and tastes fine toasted
Cook From Scratch More Often
Ready meals and pre-prepared food carry a huge markup. A few basic cooking skills save hundreds per year:
- A homemade spag bol costs roughly £1.20 per portion vs £2.50+ for a ready meal
- Learn 5 base recipes: stir fry, pasta sauce, curry, soup, and a one-pot stew. These cover most weeknight dinners
- Buy whole chickens instead of breast fillets — roast on Sunday, use leftovers for sandwiches and curry through the week
- Dried pasta, rice, tinned tomatoes, tinned beans, and frozen veg are your best friends — cheap, long-lasting, and versatile
- Porridge oats for breakfast cost roughly 5p per serving. Even the cheapest branded cereal is 5x more expensive
Reduce Food Waste
The average UK household throws away £700 worth of food every year. Cutting waste is essentially free money:
Storage hacks: Keep bananas separate from other fruit (they speed up ripening). Store bread in the freezer. Keep potatoes and onions in a cool dark place but not together.
Use your freezer: Almost everything freezes well — leftover curry, bread, milk, grated cheese, herbs in olive oil, overripe bananas for smoothies.
Understand date labels: 'Best before' is about quality, not safety. Food past its best-before date is usually fine. 'Use by' is the safety date — respect it for meat, fish, and dairy.
Track what you throw away for one week. Most people are shocked. Once you see the waste, you naturally buy less of what you don't use.
Set a Weekly Grocery Budget and Track It
None of these tips work long-term without tracking. Set a realistic weekly grocery budget and monitor it:
Benchmarks for UK households in 2026:
• Single person: £30–50 per week
• Couple: £50–70 per week
• Family of four: £70–100 per week
These are comfortable but frugal budgets. You can go lower with effort, but start realistic.
Use SYM to track your grocery spending as a saving goal — seeing your progress week by week builds the habit. When you see you've saved £200 in a quarter just on food, the motivation compounds.
The key is consistency, not perfection. Even saving £10 per week on groceries means £520 back in your pocket by the end of the year.
FAQ
Is Aldi really cheaper than Tesco?
Yes, consistently. Which? and multiple price comparison studies show Aldi is 20–30% cheaper than Tesco for a comparable basket. The main trade-off is less brand choice and a smaller range, but most households find everything they need.
How much can I realistically save on groceries per month?
Most UK households can save £80–150 per month by combining meal planning, switching supermarkets, and reducing waste. That's £1,000–1,800 per year — enough to build a solid emergency fund or fund a holiday.
Are budget supermarkets lower quality?
No. Aldi and Lidl own-brand products regularly win blind taste tests against premium brands. Their fresh produce, dairy, and bakery items are sourced from the same UK suppliers as the Big Four supermarkets.
