How This Works

Weekly grocery estimates are based on UK average spend data from ONS and supermarket research. Budget supermarkets (Aldi, Lidl) are typically 30–40% cheaper than premium chains for equivalent nutrition. Vegetarian and vegan diets can be cheaper (no meat costs) but can be similar or higher if relying on processed meat substitutes.

Top money-saving strategies: (1) Meal plan for the week before shopping — reduces waste and impulse buys. (2) Buy supermarket own-brand for staples — often identical quality to branded at 30–50% less. (3) Freeze meat, bread and leftovers to prevent waste. (4) Shop weekly yellow-sticker reductions (usually 6–9pm in most supermarkets). (5) Buy seasonal produce — often cheaper and fresher. (6) Use cashback apps (Shopmium, CheckoutSmart). (7) Grow your own herbs — small pots save £10–20/month vs buying cut herbs.
