The weekly food shop is one of the biggest bills most UK households face. According to ONS Family Spending data, the average household spends around £70 per week on food and drink — over £3,600 a year — and a family of four can easily top £110–£140 a week. Food price inflation has cooled in 2026 (2.2% in the year to May, the lowest in about 18 months), but prices are still far above where they were a few years ago. The good news: the supermarket shop is also one of the easiest bills to cut. These 14 tips can realistically save a typical family £1,000 or more per year without eating any worse.
Supermarkets are designed to make you spend more than you planned. Every tip below comes down to the same idea: decide what you're buying before you walk in (or log on), and make the store work to your plan — not theirs.
Meal planning is the single most effective grocery-saving habit. Plan 5–7 dinners for the week, write a list from the plan, and buy only what's on the list. Households that switch from ad-hoc shopping to meal planning routinely cut 15–25% from their bill — because almost everything in the trolley now has a purpose. Potential saving: £15–£25/week for a family.
The classic "downshift challenge": swap each item down one tier — branded to supermarket own-label, own-label to value range. Blind taste tests repeatedly show most people can't tell the difference on staples like tinned tomatoes, pasta, flour, cereal and cleaning products. Downshifting most of a trolley typically cuts the bill by around 30%. Try it for one week; keep the swaps you don't notice.
Tesco Clubcard Prices, Sainsbury's Nectar Prices, Lidl Plus and the Co-op Member Prices now gate the biggest discounts behind loyalty schemes, with promoted items often 20–40% cheaper. The cards are free, so if you shop there anyway, always scan one. The catch: loyalty deals are designed to tempt you into extras. Use them on things already on your list — don't add items just because they're "on offer".
The shelf label's small print shows the price per 100g, per litre or per item. This is the only fair way to compare — bigger packs are usually cheaper per unit, but not always, and supermarkets know shoppers assume they are. Thirty seconds of squinting at unit prices across a full shop adds up surprisingly fast.
Aldi and Lidl consistently sit at the bottom of monthly price-comparison surveys for a typical basket. You don't have to move your whole shop: many households do a core shop at a discounter and top up brands and specifics elsewhere. If you currently shop at a "big four" supermarket, a discounter core shop commonly saves 10–20%.
Supermarkets reduce short-dated food several times a day, with the biggest markdowns (up to 75–90% off) usually in the evening — often from around 7pm, though times vary by store. Yellow-sticker meat, bread and ready meals nearly all freeze well. Ask staff when your local store does its final reductions; regulars learn the schedule quickly.
It sounds trivial, but shopping hungry measurably increases impulse buys. So does frequency: every extra trip is another walk past the bakery smell and the promo ends. Aim for one main shop a week plus, at most, one milk-and-bread top-up. Cutting from four store visits to two is one of the quietest ways to spend less.
Doubling a recipe costs far less than double — you're already paying for the oven, the base ingredients and your time. Freeze the second half in portions and you've also killed the midweek takeaway, which is where food budgets really bleed. A £6 batch curry that replaces a £25 delivery pays for a lot of tupperware.
WRAP (the UK's waste-reduction body) estimates UK families throw away several hundred pounds of edible food a year — commonly quoted at around £1,000 for a family with children. The fixes are simple: check the fridge before shopping, store food correctly, trust your senses on "best before" dates (they're about quality, not safety — "use by" is the safety one), and have one "use-it-up" meal a week built from whatever's left.
Meat is usually the most expensive line in the trolley. You don't need to go vegetarian: stretching mince with lentils, or making one or two dinners a week bean- or egg-based, cuts cost and works fine with most family favourites — chilli, bolognese, curry. A 500g pack of dried red lentils costs around £1 and replaces roughly its own weight in mince.
"Wonky" or imperfect ranges are the same vegetables at a lower price. Frozen fruit and veg are often cheaper still per portion, are nutritionally comparable (frozen within hours of picking), and produce zero waste because you use only what you need. Frozen berries, peas, spinach and fish are the classic wins.
Rice, spices, pulses, coconut milk, soy sauce and noodles are frequently far cheaper in the world food aisle than the identical products shelved elsewhere in the same store — often in bigger packs. The same logic applies to local international grocers, which regularly beat supermarkets on these staples.
Finally, none of the tips stick without a number to aim at. Decide a weekly food budget, pay attention to the running total as you shop (a calculator on your phone, or shop online where the basket totals itself), and review it monthly. Most households that start tracking find 10% of "mystery spend" almost immediately.
Meal planning + downshifting + a discounter core shop + halving food waste: £1,000–£1,500 per year for a typical family of four — without cutting quality or portions. Start with tips 1 and 2 this week.
