How to save on groceries in London and which shops to avoid

You can save a lot on groceries in London if you know where to buy the basics and which shops to avoid for a big shop.

Where to shop well

• Aldi and Lidl — usually cheaper than the big chains for basics.
• Supermarket own brands — almost always cheaper than brands, same quality.
• Markets — for fruit, veg and herbs.

The key trick — price per kilo

Compare not the pack price but the price per kg or per 100g (in small print on the label). A bigger pack isn't always better value.

Discounts and reductions

In the evening supermarkets add yellow stickers to short-dated items. Loyalty cards (Clubcard, Nectar) give lower prices — but compare, as offers aren't always a saving.

Which shops to avoid for a big shop

The most expensive are convenience and express formats (Tesco Express, Sainsbury's Local, Co-op), minimarkets in tourist and central areas, and petrol-station shops. Handy for a top-up, but you'll overpay on a big shop.

More ways

• Batch cook and freeze in portions.
• Apps that sell surplus food from cafes and shops help you buy cheaper.
