How to save money on your food shop in the UK

Food is one of the few big bills you can change every single week. You do not need to give up everything you enjoy or live on beans. A handful of habits, used consistently, can bring a UK food shop down noticeably. Here is a practical, no-nonsense guide to spending less at the supermarket.

Step 1: Find out what you actually spend

Most people underestimate their food spending, because it is spread across a big weekly shop, top-up trips, meal deals, takeaways and coffees. Before you cut anything, add up everything you spent on food and drink over the last four weeks. Your banking app will usually let you search by shop name or filter by "groceries".

Split it into three groups:

• Main shop: the big weekly or fortnightly trip, in store or online.
• Top-ups: bread, milk and "while I'm here" extras from the corner shop or a local express store.
• Eating out and convenience: lunches, meal deals, takeaways, delivery apps and coffees.

Once you can see the three totals, set a realistic weekly food budget. Make it a number you could hit next week, not a dream figure. You can lower it later. If you have not set up a full budget yet, our guide to making a monthly budget in the UK shows where food fits alongside rent and bills.

Step 2: Plan meals before you shop

Meal planning is the single habit most money guides agree on, for good reason. When you know what you are cooking, you buy only what you need and waste less. It does not have to be complicated:

1. Check what you already have. Look in the fridge, freezer and cupboards first and build two or three meals around what needs using up.
2. Plan five or six dinners, not seven. Leave a night for leftovers or a "fridge clear-out" meal such as an omelette, soup or fried rice.
3. Reuse ingredients across meals. A bag of spinach can go in a curry on Monday and a pasta bake on Wednesday. One chicken can make a roast, then sandwiches, then stock for soup.
4. Plan lunches too. Leftovers and packed lunches are where many people save the most, because bought lunches add up fast over a working week.
5. Write the list from the plan. Then stick to it in the shop.

Step 3: Compare unit prices, not shelf prices

The biggest pack is not always the cheapest per kilo, and a multibuy is not always a bargain. The number to compare is the unit price: the price per kilogram, per litre or per item, usually shown in small print on the shelf label or next to the product online.

Unit pricing rules in Great Britain were tightened from 6 April 2026. Under the amended Price Marking Order, when a product is sold at more than one price, such as a normal price and a loyalty card price, shops must show each selling price and each unit price, and make any conditions (like "with loyalty card") clear and close to the product. That makes like-for-like comparison easier, so get into the habit of reading that small print. Northern Ireland has its own version of the rules.

Use unit prices to check:

• Big packs against small packs.
• Branded against own-brand and value ranges.
• Fresh against frozen or tinned.
• Pre-prepared (grated cheese, chopped veg, pre-cut fruit) against doing it yourself.

Step 4: Trade down a brand level

Most supermarkets have three tiers: branded, own-brand and a value or "essentials" range. Try dropping one level on the things you will not notice, such as tinned tomatoes, pasta, rice, flour, frozen veg, cleaning products and kitchen roll. Keep the brands you genuinely prefer. A simple test is to buy the cheaper version once; if nobody notices, it stays on the list.

Step 5: Use loyalty schemes, but carefully

Many UK supermarkets now offer lower prices to loyalty card or app members. If you already shop somewhere, it is usually worth joining its free scheme so you are not paying the higher non-member price. But do not let a member price pull you into buying things that were not on your list. A discount on something you did not need is still money spent.

Step 6: Cut food waste

Every bit of food that goes in the bin is money thrown away. A few easy fixes:

• Know your dates. "Use by" is about safety, so do not eat food after it. "Best before" is about quality, so food is often fine to eat after that date if it has been stored properly.
• Use the freezer. Bread, milk, grated cheese, cooked rice (cooled quickly), sliced fruit and leftovers can all be frozen. Label everything with the date.
• Batch cook. Make a double batch of chilli, soup or bolognese and freeze portions for busy nights, which also stops a "can't be bothered" takeaway.
• Store food well. Keep the fridge at 5°C or below, as recommended by the Food Standards Agency, and keep opened food sealed.

Apps such as Too Good To Go (discounted surplus food bags from shops and cafés) and Olio (free food shared by neighbours and local businesses) can also help, depending on where you live.

Step 7: Shop smarter, not more often

• Shop less often. Fewer trips means fewer impulse buys. Top-up trips are where budgets quietly leak.
• Try online shopping. Ordering online makes it easier to stick to a list and see the running total, though check delivery charges and minimum spends.
• Check the reduced section. Yellow-sticker food near its date can be a bargain if you will eat or freeze it that day.
• Consider a cheaper supermarket. If you always use the same shop, try a discounter or market for a few weeks and compare your receipts.
• Do not shop hungry. It sounds obvious, but it really does make extras more tempting.

Step 8: Check if you can get help with food costs

If you are on a low income, make sure you are not missing out on support:

• NHS Healthy Start (England, Wales and Northern Ireland). If you are more than 10 weeks pregnant or have a child under 4, and get certain benefits such as Universal Credit (with take-home pay within the scheme's limit), you may get a prepaid card to spend on milk, fruit, vegetables, pulses and infant formula. From April 2026 the scheme pays £4.65 a week during pregnancy and for each child aged 1 to 4, and £9.30 a week for each baby under one. You can also get free vitamins. Check eligibility at healthystart.nhs.uk.
• Best Start Foods is the Scottish equivalent, run by Social Security Scotland.
• Free school meals. All children in reception, year 1 and year 2 at state schools in England get free school meals, and eligibility for older children depends on your circumstances. Rules differ in Wales, Scotland and Northern Ireland, so check with your council.
• Food banks and community pantries are there if you are struggling. Citizens Advice can refer you and check whether you are getting all the benefits you are entitled to.

This is an example only, and your plan should fit your tastes, dietary needs and cooking time. The point is the pattern: cook once, eat twice, and use up what you buy.

Keep the savings

If you cut your food shop, decide where the difference goes before it disappears into other spending. Moving it straight into savings or towards a debt makes the effort count. Our guides to building an emergency fund and cutting household bills have more ideas for putting that money to work.
