You can put together a genuinely decent weekly shop for around £20 if you buy surplus. Not a sad one, but an actual week of meals, with brands you recognise. The trick is knowing what to buy in bulk, what to build your meals around, and where the real savings hide. Here's how a £20 shop actually comes together.

Why £20 is realistic (and why it isn't at a supermarket)

Walk into a big supermarket with a £20 note and you'll come out with about three days of food, if you're careful. That's just the maths of full retail pricing.

Surplus changes the maths entirely. When a tin of soup is 40p instead of £1.40, or a box of cereal is £1 instead of £4, your twenty quid stretches roughly three times further. Same brands, same products. They've just come to us through overproduction, a packaging redesign, or a best-before date that's closer than a supermarket wants to deal with.

So this isn't a guide about eating less. It's a guide about paying less for the same food.

Start with the backbone, not the treats

The single biggest mistake people make with a tight budget is shopping in the order they'd normally shop, grabbing whatever looks good and hoping it adds up to meals. It rarely does.

Work backwards instead. Get your carbohydrate base first, then protein, then the stuff that makes it taste like something you actually want to eat.

•     Base (aim for £4–£6): Pasta, rice, noodles, potatoes, oats. These are cheap even at full price and absurdly cheap on surplus. A few kilos here does most of the heavy lifting for the week.

•     Protein (£6–£8): Tinned beans, lentils, chickpeas, tinned fish, eggs. Frozen meat if it's in. Beans and lentils are the unsung heroes here: filling, versatile, and they keep indefinitely.

•     Flavour (£3–£5): Cooking sauces, tinned tomatoes, stock cubes, spices, condiments. This is where surplus really shines, because branded sauces are heavily marked up at retail.

•     Extras (whatever's left): Snacks, biscuits, drinks. Buy these last, with what's left over. If you buy them first you'll blow half the budget before you've got a single meal sorted.

What a £20 basket might actually look like

Prices move constantly with surplus (that's the nature of it), but here's the shape of a shop that feeds one person comfortably for a week, or stretches to two if you're clever with portions:

•     2kg pasta and 1kg rice, the base for at least eight meals

•     6–8 tins: chopped tomatoes, baked beans, chickpeas, tuna

•     A dozen eggs

•     2–3 cooking sauces (curry, pasta, stir-fry)

•     A bag of frozen veg

•     Cereal or porridge oats for breakfasts

•     Bread, or flour if you fancy it

•     Tea or coffee

•     Whatever snacks the remaining couple of pounds covers

That's genuinely a week of food. Pasta with tomato sauce, rice and chickpea curry, eggs on toast, tuna pasta, beans on toast, porridge in the mornings. None of it exciting written down, all of it perfectly good to eat.

The bits that make the difference

A few habits that quietly double what your money does:

•     Buy the multipack. Almost always cheaper per unit, and with surplus the gap is often ridiculous. If you'll eat it, buy the bigger one.

•     Don't be loyal. The whole point of surplus is you take what's there. If it's Heinz this week and a different brand next week, so what? You're saving 60%.

•     Check the freezer aisle. Frozen veg and meat are cheaper, last longer, and there's no waste from something going off in the fridge.

•     Stock up on the long-life stuff when it's cheap. Tins, pasta, rice and cooking sauces keep for months. When they're at their cheapest, buy for three weeks, not one.

•     Plan two or three meals, not seven. Cook once, eat twice. It's less faff and it wastes far less food.

What about the dates?

Most of the savings on surplus food come from stock that's near or past its best-before date, and that trips people up, because best-before sounds more serious than it is.

Best-before is about quality, not safety. A tin of beans a month past its best-before date is fine. Pasta, rice and tinned goods are fine for a long time after. The date that genuinely matters is the use-by date, which appears on fresh, high-risk foods like meat and fish, and that one you follow strictly. Our guide to best-before vs use-by dates explains the difference properly if you want the full picture.

Ready to try it?

The £20 shop isn't a stunt. It's just what happens when you stop paying retail markup on food that's perfectly good. Have a look through the latest deals and see what's in this week. The range shifts constantly, which is half the fun of it.

Frequently asked questions

Can you really do a weekly shop for £20?

Yes, if you shop surplus rather than at full retail prices. Building the shop around cheap staples (pasta, rice, tinned goods, eggs and frozen veg) and buying branded products at surplus prices makes a week of meals achievable for around £20 for one person.

What should I buy first on a tight budget?

Start with your carbohydrate base (pasta, rice, potatoes, oats), then protein like tinned beans, lentils, eggs or tinned fish, then sauces and flavourings. Buy snacks and treats last, with whatever's left over.

Is surplus food safe to eat?

Yes. Surplus food is normal, in-date stock that can't be sold through usual retail channels, usually because of overproduction, packaging changes or a short best-before date. Best-before is a quality date, not a safety one, and reputable surplus retailers never sell past use-by dates.

How do I stop food going to waste on a budget shop?

Buy more long-life and frozen items and fewer fresh ones, plan two or three meals you can repeat rather than seven different ones, and cook in batches. Most waste comes from fresh food bought with good intentions and not used in time.

Where can I do a cheap weekly shop in the UK?

Surplus and clearance retailers like Peeko sell big-brand groceries at a fraction of supermarket prices. The range changes as new stock arrives, so it's worth checking regularly and stocking up on staples when they're cheapest.
