Food shopping is the third-largest household expense in the UK after housing and transport, with the average family spending around £100–£120 per week. That's over £5,000 a year — and much of it is spent on impulse purchases, brand loyalty, and shopping habits that don't serve your wallet. The good news is that cutting 30% from your grocery bill doesn't mean eating beans on toast every night. It means shopping smarter: knowing when to go own-brand, how to plan meals, and when to shop for the best deals.
Own-Brand Products: The Biggest Instant Saving
Supermarket own-brand products are 20–50% cheaper than branded equivalents, and in blind taste tests, they frequently match or beat the brands. Aldi and Lidl's entire model is built on this — their products are often made in the same factories as branded goods. For mainstream supermarkets, try their standard own-brand range first; if that's not to your taste, the 'Finest'/'Taste the Difference' tier is still cheaper than most brands. Save brand loyalty for the few products where you genuinely notice a difference.
- Own-brand is typically 20–50% cheaper than branded
- Many own-brand products are made in the same factories
- Try standard own-brand first, then premium own-brand
- Keep branded products only where you genuinely taste the difference
- Own-brand medicine is identical (same active ingredients, fraction of the price)
Is Aldi/Lidl really cheaper for a full weekly shop?
Yes — consistently. Which? magazine's regular price comparisons show Aldi and Lidl are typically 25–30% cheaper than the Big 4 (Tesco, Sainsbury's, Asda, Morrisons) for a comparable basket. The savings are most dramatic on basics, dairy, and meat.
Meal Planning and List Discipline
Walking into a supermarket without a plan is the single most expensive grocery mistake. Spend 15 minutes on Sunday planning your meals for the week, check what you already have, and write a specific shopping list. Stick to the list. Studies show that shoppers without a list spend 20–40% more than planned, driven by impulse buys and promotions. Plan meals around what's on offer that week — check your supermarket's app for deals before you plan. Build 2–3 'flex meals' around pantry staples in case plans change.
- Plan meals for the week every Sunday (15 minutes)
- Check what you already have before writing your list
- Stick to the list — no impulse additions
- Plan around what's on offer that week
- Include 2–3 flexible meals from pantry staples
- Shop after eating, never hungry
Timing Your Shop for Maximum Savings
Supermarkets reduce items at predictable times. Yellow-sticker reductions typically happen mid-afternoon (2–4 PM) and again in the final hours before closing. These reductions can be 50–90% off. Items nearing their best-before date are perfectly safe to eat or can be frozen immediately. Some supermarkets have dedicated 'reduced' sections; others scatter items throughout the store. The Too Good To Go app also lets you buy surplus food from supermarkets and shops for a fraction of the price — magic bags cost £2–£4 and typically contain £10–£15 of food.
- Yellow sticker reductions: typically 2–4 PM and before closing
- Reductions of 50–90% are common
- Freeze reduced items immediately for later use
- Too Good To Go app: surplus food bags for £2–£4
- Shop seasonal produce — it's cheaper and better quality
- Compare unit prices (price per kg/litre), not just pack prices
Batch Cooking and Freezer Strategy
Batch cooking is the bridge between meal planning and actual savings. Spending 2–3 hours on a Sunday making large batches of curry, chilli, soup, and pasta sauce gives you ready meals for the week at a fraction of the cost. A home-made curry costs around £1.50 per portion compared to £3–£5 for a supermarket ready meal. Invest in good freezer containers and label everything with the date. A well-stocked freezer means you're never tempted by expensive takeaways on tired weeknights. Track your food spending in SYM to see the savings compound week by week.
