Your weekly shop does not have to drain your bank account
Grocery spending is one of those costs that creeps up on you. You pop into the supermarket for a few bits, and somehow walk out £80 lighter. According to the Office for National Statistics, the average UK household spends north of £60 per week on food and non-alcoholic drinks. Over a year, that is more than £3,000 — and for many families, quite a bit more. The thing is, most people could trim 20 to 30 percent off that number without eating worse or spending hours hunting for bargains. It comes down to a handful of habits that, once you build them, run on autopilot.
1. Plan your meals — even loosely
Meal planning has a reputation for being tedious, but it does not need to be a colour-coded spreadsheet. Even a rough idea of five evening meals for the week ahead makes a massive difference. The reason is simple: when you know what you are cooking, you buy what you need. When you do not know, you buy what catches your eye — and half of it ends up going off before you get around to using it. Spend ten minutes on a Sunday evening jotting down meals, then write your list. That ten minutes will pay for itself many times over.
2. Check the leaflets before you go
Every major UK supermarket releases weekly promotional leaflets, and they are worth a look before you commit to a store. On CatalogFlix, you can flick through offers from Lidl, Sainsbury's, Tesco and others without visiting each website separately. If lamb mince is on offer at one store and chicken thighs at another, you can shape your meal plan around the deals rather than paying full whack. It takes a few minutes and genuinely shaves pounds off the bill.
3. Actually use your loyalty cards
Millions of people have a Clubcard or Nectar card sitting in their wallet that they scan out of habit but never really engage with. The real savings come from the personalised coupons and app-only offers. Tesco Clubcard prices, for example, can knock 30 to 50 percent off selected items each week — but only if you scan the card. Lidl Plus regularly sends out digital coupons that stack up over time. If you are going to carry the card anyway, you might as well squeeze every penny out of it.
4. Buy what is in season
British strawberries in June cost a fraction of the imported ones in January, and they taste worlds apart. The same goes for asparagus in spring, sweetcorn in summer, and root vegetables through the colder months. Seasonal produce is cheaper because there is more of it and it has not been flown halfway around the world. Your meals will taste better too, which is a nice bonus. The Love Food Hate Waste website has a handy seasonal calendar if you are not sure what is at its best right now.
5. Compare price per kilogram, not price per pack
This is one of those things that sounds obvious but catches people out constantly. A 500g bag of rice for £1.20 looks cheaper than a 1kg bag for £2.00, but the bigger bag is actually better value per gram. Supermarkets are legally required to show the price per kilogram (or per litre) on shelf labels, so glance at that number rather than the headline price. You will sometimes find that the "family size" pack is worse value than two smaller ones on promotion.
6. Do not shop when you are starving
This sounds like the kind of tip your nan would give you, but the research backs it up. Shopping hungry genuinely leads to more impulse purchases — not just food, but non-food items too. Your brain is in acquisition mode and everything looks appealing. Have a banana or a biscuit before you set off. It is a tiny thing that stops you coming home with three sharing bags of crisps you did not plan on buying.
7. Give own-brand a proper chance
If you have not tried supermarket own-brand products recently, you might be surprised. Tesco, Sainsbury's, Lidl and Aldi all produce own-label ranges that are typically 20 to 40 percent cheaper than the branded version — and blind taste tests run by Which? regularly show shoppers cannot tell the difference. Start with the easy swaps: tinned tomatoes, pasta, rice, flour, cleaning products, bin bags. Once you realise how much you are saving on those, you will naturally start trying own-brand versions of other things too.
8. Stop throwing food in the bin
The average UK household bins around £700 worth of perfectly edible food every year. That is not potato peelings and chicken bones — it is the lettuce that went slimy, the bread that went mouldy, and the leftovers nobody fancied reheating. Freeze things before they go off. Use up what is in the fridge before buying more. Learn the difference between "best before" (a quality suggestion, not a safety deadline) and "use by" (which you should respect, especially for meat and fish). Your kitchen bin should not be the most expensive appliance in the room.
9. Hit the reduced section
Yellow-sticker shopping has become something of a sport in the UK, and for good reason. Most supermarkets mark down fresh items in the evening — typically from around 6pm onwards, though it varies by store. Tesco uses yellow stickers, Sainsbury's uses red ones, and Lidl has a dedicated reduced shelf. The products are perfectly good; they simply need eating or freezing that day. If you time your shop right, you can pick up meat, fish, bread and ready meals at half price or less.
10. Split your shop across stores
No single supermarket is cheapest for everything. Lidl and Aldi consistently win on everyday basics, but Tesco or Sainsbury's might have better offers on branded products in any given week. If you live near multiple stores, it pays to cherry-pick. CatalogFlix makes this straightforward — you can browse all the current leaflets side by side and figure out which store deserves your money that week. Even splitting your shop between two stores can knock £10 to £15 off the weekly total.
Making it stick
None of these tips require heroic effort. The ones that save the most money — meal planning, checking leaflets, and reducing waste — take perhaps 20 minutes a week combined. That is a pretty good return on your time when it translates to £50 or more back in your pocket every month. The Money Saving Expert supermarket guide is another solid resource if you want to go deeper. Start with one or two changes this week, add more as they become second nature, and you will wonder why you did not do it sooner.
