15 Ways to Save Money on Groceries in the UK in 2026

UK food prices rose sharply over the past three years, and while inflation has slowed, prices haven't fallen back. The average UK household spends around £65–£80 per week on groceries. With the right tactics, most households can cut that by £15–£25 per week — saving £60–£100 per month — without eating worse. Here are 15 strategies that work.

Supermarket own-brand products are often manufactured in the same factories as branded goods, just with a different label. Aldi and Lidl's entire range is own-brand, which is why they're consistently 20–30% cheaper than the main supermarkets. Even within Tesco, Sainsbury's, or Asda, switching from branded to own-brand on everyday items like pasta, tinned tomatoes, cereals, and cleaning products can save £15–£25 a week.

Do your main shop at Aldi or Lidl, then top up at a larger supermarket for anything you can't find there. Studies by Which? and MoneySavingExpert consistently show Aldi and Lidl are 15–25% cheaper for a comparable basket of goods. If you currently spend £70/week at Tesco, switching to Aldi-first could save you £10–£15 per week immediately.

Meal planning is the single most effective way to reduce food waste and grocery bills. Plan seven dinners, five lunches, and seven breakfasts before you go shopping. Write a shopping list based on exactly what those meals need. Stick to the list. The impulse buys and 'just in case' purchases are where grocery budgets leak — a shopping list plugs that leak.

Tesco Clubcard prices offer significant discounts for members — sometimes 30–40% off. Sainsbury's Nectar card works similarly. These loyalty schemes are free and the discounts are substantial. Scan your card every time you shop. Accumulate points and use them during big shops (before Christmas, before a holiday) or convert Tesco Clubcard points to Avios for travel rewards at a boosted rate.

Most UK supermarkets reduce items approaching their use-by date in the afternoon (typically 4–8 PM). Bread, meat, prepared foods, and dairy can be reduced by 50–75%. Buy marked-down meat and freeze it immediately. You can save £10–£20 a week with strategic yellow sticker shopping if you're flexible about what you eat. Apps like Too Good To Go also offer surplus food from supermarkets and restaurants at deep discounts.

The average UK household throws away around £700 of food per year. Most of that is avoidable. Learn what freezes well (bread, bananas, cooked rice, batch-cooked meals, most proteins) and freeze anything approaching its use-by date rather than binning it. A well-stocked freezer also means fewer emergency takeaway orders when you 'have nothing to eat' — because there's always something in the freezer.

Pasta, rice, tinned goods, cooking oil, washing powder, toilet roll — these don't expire quickly and buying in larger quantities is almost always cheaper per unit. Check the unit price (price per 100g or per litre) rather than the shelf price. Costco membership pays for itself quickly if you have storage space and regularly buy these items. Amazon Subscribe & Save is another option for household staples delivered on a schedule at a discount.

Pre-cut vegetables, pre-marinated meats, ready meals, and meal kits all carry a significant convenience premium. A ready-prepared stir fry kit costs £4–£6. The same meal made from scratch costs £1.50–£2 and takes 15 minutes. If you rely on convenience foods for 3–4 meals a week, shifting two of those to scratch cooking could save £15–£20 per week. Pick simple recipes that genuinely don't take much time rather than complex dishes you'll avoid.

If you don't know what you currently spend on food, you can't reduce it meaningfully. Check your bank statements for the last three months and calculate your average grocery spend. Many banking apps categorise this automatically. Once you have a baseline, set a target — £10 less per week is achievable for most households — and actively track against it. What gets measured gets managed.
