Switching to own-brand and frozen items can cut grocery costs by up to 50%, according to retail experts. Simple changes in shopping habits, like using a basket instead of a trolley, can also prevent overspending.
Check Your Kitchen First
Cathrine Jansson-Boyd, professor of consumer psychology at Anglia Ruskin University, says many shoppers waste money by not knowing what they already have. Taking inventory of cupboards, fridge, and freezer before shopping prevents buying duplicates and reduces food waste.
Set a Budget and Stick to It
Having a fixed budget helps focus on offers and avoid impulse buys. Loyalty apps with scan-and-shop features track total cost in real time, making it easier to stay within limits.
Own-Brand and Frozen Products Can Save 50%
Oisín Hanrahan, CEO of supply chain platform Keychain, recommends being flexible with brands. Private label products have surged in popularity due to the cost of living crisis, offering significant savings. Frozen fish can be up to 50% cheaper than fresh, with the added benefit of longer shelf life. For meat, choose cheaper cuts like chuck or stewing steak, and chicken legs instead of breast or thighs.
Buy Whole, Not Pre-Prepared
Pre-cut, minced, or grated products carry a markup. For example, a clove of garlic can cost four times less than pre-minced garlic. Taking time to prepare vegetables yourself saves money in the long run.
Get Creative with Recipes
Don't feel obligated to buy every ingredient a recipe calls for. Substitute with what you already have at home, such as unused spices. This reduces waste and cuts costs.
Compare Supermarkets and Unit Prices
Food prices vary by store. Check price changes and compare online. Aldi was named the cheapest UK supermarket in February 2026 by Which. Always look at unit prices, not just sale signs, to ensure true value.
Use a Basket, Not a Trolley
A basket fills quickly and gets heavy, naturally limiting purchases. Avoid supersized products unless you will use them all; bulk buying is only a deal if nothing goes to waste.
These strategies, backed by consumer psychology and retail expertise, can help households save significantly on weekly grocery bills.
