How to spend less at the supermarket without eating badly

Food shopping is one of the few significant household costs you can actively influence every week. Unlike rent or energy, it responds directly to small changes in behaviour. Most households can reduce their supermarket spend by 15 to 25 per cent without eating worse — often by making a handful of adjustments to when, where, and how they shop.

Shop with a list and a rough total in mind

Going to a supermarket without a list almost always results in spending more than intended. Before you go, check what you already have, plan the meals you will make, and write a list from those meals. A rough spending target — even a loose one — keeps you anchored when you are browsing the aisles.

Try own-brand products on key staples

Supermarket own-brand products on staples — pasta, rice, tinned tomatoes, flour, oil, bread, milk, eggs, frozen vegetables — are typically 30 to 50 per cent cheaper than branded equivalents and often identical in quality. Switching just these categories can reduce a typical weekly shop by ten pounds or more.

Check unit prices, not shelf prices

A larger pack is not always cheaper per unit. Supermarkets are required to display the price per 100g or per litre alongside the shelf price. Comparing these rather than the headline price ensures you are actually getting better value when you buy in bulk.

Use the yellow sticker section

Most supermarkets reduce items approaching their use-by date, typically in the afternoon or evening. Meat, fish, dairy and prepared foods are the most common reductions. Items can be frozen the same day if you are not using them immediately. Regular yellow sticker shopping can be a meaningful saving across the month.

Reduce food waste

UK households throw away roughly 20 per cent of the food they buy. A meal plan, a weekly fridge check before shopping, and learning to use ingredients across multiple meals all reduce waste. Money spent on food that ends up in the bin is the most avoidable spending category in most households.

Compare across supermarkets for your main items

Price comparison tools like mysupermarket.com let you check the cost of your usual shopping basket across different retailers. Doing this once can reveal whether switching your main shop — or splitting between two stores — would produce a meaningful saving.
