UK Grocery Budget Tips 2026 | Cut Your Food Shop by £100/Month

Meal Planning: The Highest-Impact Change

Nothing cuts grocery costs like meal planning. Households that meal plan spend 20-30% less on food, waste significantly less, and eat healthier. The process: before your weekly shop, decide exactly what you're having for each meal. Write a shopping list based only on what you need. Stick to the list. That's it. The harder part is building the habit. Start with just planning dinners — one plan per week. Batch cook on Sundays so Monday to Wednesday are covered without thinking. The mental load of 'what's for tea?' disappears, and so does the £15 panic takeaway.

Switch to Aldi or Lidl

This sounds obvious, but the data is stark. Which? analysis consistently shows that a typical basket at Aldi or Lidl costs 30-40% less than the same basket at Tesco, Sainsbury's, or Asda. A family of four switching from a mid-tier supermarket to Aldi could save £100-150/month. You don't have to switch 100% — buying your main weekly staples from Aldi and just topping up at a larger supermarket for specialist items is a common and effective approach. The quality of Aldi and Lidl products has improved dramatically and now regularly beats branded equivalents in taste tests.

Own Brand vs. Branded: What's Actually Worth It

Own-brand products cost on average 30-50% less than branded equivalents. In blind taste tests, own-brand versions of pasta, rice, canned goods, dairy, eggs, and frozen vegetables are consistently rated as good as or better than branded versions. Items where own-brand is almost always fine:

•Pasta, rice, oats, flour — identical quality at half the price

•Tinned tomatoes, pulses, beans — no meaningful difference

•Frozen vegetables — often more nutritious than fresh

•Dairy (milk, butter, cheese) — slight taste differences at most

•Cooking oils, vinegars, condiments

Reduce Food Waste

UK households throw away around £700 worth of food per year on average — roughly £60/month of uneaten food. The biggest culprits are fresh produce, bread, and cooked meals that weren't eaten. Fixes:

•FIFO: First In, First Out. Put new food behind older food in the fridge and cupboard.

•Use the freezer: Bread, meat, cheese, cooked rice, soup — all freeze well. Freeze before the use-by date, not after.

•Check fridge temperature: Should be 1-5°C. At the correct temperature, food lasts significantly longer.

•Ugly veg boxes: Oddbox and similar deliver cheaper imperfect produce that would otherwise be wasted.

•Use apps like Too Good To Go: Collect surplus food from local restaurants and cafes for £2-4 a bag.

Loyalty Schemes and Cashback

Supermarket loyalty schemes have gotten much better. Tesco Clubcard prices offer 20-50% off on hundreds of items. Sainsbury's Nectar prices are similar. Using these schemes without changing where you shop can save £15-30/month. Add cashback apps like Shopmium, CheckoutSmart, or Boots Advantage card for additional savings on specific items. Stack these — a Clubcard price plus a cashback offer on the same item is perfectly legal and very satisfying.
