Last updated: October 2026. Grocery prices and ranges vary by supermarket and location.
The “downshift challenge” is one of the simplest grocery experiments I use: try a cheaper version of something you normally buy and keep the swap if you like it.
When we were saving our first house deposit on one salary, the supermarket was where I found the easiest wins. I didn’t want our family to feel deprived, so instead of cutting things out, I started trying the cheaper version of the things we already bought. Some swaps we loved, some went straight back on the shelf, and that’s exactly how it should be. I can’t promise you a magic percentage, because every family’s basket is different, but I can show you how to find the swaps that work for yours.
How the downshift works
If you usually buy a premium range, try the standard version. If you usually buy a major brand, compare the supermarket own-brand. If you already buy own-brand, see whether a value version suits you.
You do not need to downshift everything. Taste, ingredients, nutrition, allergies, dietary requirements and quality all matter.
Compare the unit price
Package sizes differ, so the cheapest-looking pack is not always the cheapest per 100g, kilogram or litre. Use the shelf unit price where available.
Don’t assume a loyalty price is automatically cheapest
The CMA’s grocery review found loyalty prices generally represented genuine savings against the retailer’s usual price, but another supermarket could still be cheaper.
Keep a simple swap list
Mine has three categories: cheaper version we like, cheaper version we don’t like, and no meaningful difference. That makes the weekly shop quicker.
Combine savings carefully
Reduced food, meal planning, food-rescue apps and cashback can all help. But a deal is only useful if you would otherwise buy or use the item.

How to run your own downshift challenge
- Pick five products you buy every week, such as bread, pasta, tinned tomatoes, cereal and washing-up liquid.
- Swap each one for the next brand down, for example from a premium brand to the supermarket’s own brand, or from own brand to the value range.
- Keep your receipts and compare the total with a normal week.
- Ask your family to rate each swap honestly. Keep the ones nobody notices and switch back where quality really matters.
Where downshifting works best
In my experience, basics such as flour, sugar, pasta, rice, tinned goods and cleaning products are usually the easiest swaps. Things like coffee, tea or a favourite cereal might be worth keeping as a treat. The aim is not to buy the cheapest thing every time, but to spend your money on the things your family actually values.
A simple 4-week downshift plan
Trying to change everything at once is how challenges fail. This gentle plan spreads the swaps out, so nobody at home feels it.
- Week 1: swap five store-cupboard basics, such as pasta, rice, tinned tomatoes, flour and sugar.
- Week 2: try cheaper cleaning and household products, like washing-up liquid, bin bags and kitchen roll.
- Week 3: move on to breakfast and lunchbox items, such as cereal, crackers, yoghurts and sandwich fillings.
- Week 4: try a few fridge and freezer items, for example frozen vegetables, cheese and chopped fruit.
At the end of each week, compare your receipt with a normal week. My grocery savings calculator shows what even a small weekly saving adds up to over a year.
Do a quick blind taste test at home
Children (and partners!) can be surprisingly loyal to a brand until they don’t know which one they’re eating. Put the branded and cheaper versions in identical bowls, label them A and B, and ask everyone to vote. If the family can’t tell the difference, or even prefers the cheaper one, that swap is a keeper.
What to check on the label before you swap
- Unit price: compare the price per 100g, kg or litre on the shelf label, not the pack price.
- Ingredients: cheaper versions can contain more water, sugar or filler, especially in things like ham, juice or ready meals.
- Traffic-light nutrition labels: check salt, sugar and fat if these matter for your family.
- Allergens: always check, because recipes and factory warnings can differ between brands.
- Pack size: a bigger pack is only cheaper if you’ll use it before it goes off.
Which supermarkets have value ranges?
Most big supermarkets have their own cheaper ranges, which makes downshifting easy. At Tesco, look for its exclusive brands such as Stockwell & Co. and Grower’s Harvest. Sainsbury’s has Stamford Street, Asda has Just Essentials and Morrisons has Savers. At Aldi and Lidl, most products are already own-label, so your downshift might simply be changing where you shop. I compare the two in Aldi vs Lidl: which is cheaper?
My downshift swap list (copy it for your fridge)
| Product | Try this swap | Worth checking |
|---|---|---|
| Pasta, rice, flour | Own-brand or value range | Usually little difference once cooked |
| Tinned tomatoes and beans | Own-brand | Thickness and salt |
| Cereal | Own-brand version of your favourite | Sugar content and the family vote |
| Washing-up liquid | Own-brand | How far a squirt goes |
| Frozen vegetables | Value range | Great for soups, stews and stir-fries |
| Cheese | Own-brand block, grated at home | Taste in sandwiches vs cooking |
| Coffee or tea | Keep as a treat if it matters to you | Downshifting isn’t all or nothing |
Downshifting works even better alongside a weekly meal plan. My guide to a cheap weekly shop for a family of four puts it all together.
Downshifting by aisle: where the biggest wins usually are
Some aisles tend to offer bigger savings than others when you try the cheaper version. Here’s where I’d look first:
- Cleaning and laundry: own-brand washing-up liquid, surface sprays and bin bags often do the job just as well.
- Baking and cupboard staples: flour, sugar, oats, rice and pasta rarely taste different once cooked.
- Tins and jars: chopped tomatoes, beans and chickpeas are easy swaps for sauces and stews.
- Frozen food: frozen vegetables and fruit are great value and cut waste.
- Medicines: pharmacy own-brand painkillers usually contain the same active ingredient as branded ones; check the label and ask the pharmacist if unsure.
Aisles where people are often happiest to keep a favourite brand include coffee, tea, ketchup and some cereals. That’s completely fine: downshifting is about choosing where your money goes, not giving up everything you enjoy.
Supermarket downshift challenge: your questions answered
Are supermarket own brands as good as branded products?
Often they’re very similar, but not always. Quality varies from product to product and supermarket to supermarket, so the best test is your own: try it, compare the ingredients and see whether your family notices.
How much can I save with a downshift challenge?
It depends on what you buy now. Families who buy lots of branded products usually save the most. Keep two weeks of receipts, one normal and one downshifted, so you can see your real saving rather than relying on someone else’s number.
Are own-brand products made in the same factories as big brands?
Sometimes, but you can’t assume it. Many own-brand products have their own recipes. Judge each product on its ingredients, price per 100g and taste.
What shouldn’t I downshift?
Anything where quality or ingredients really matter to you, such as allergy-safe foods, special diets or products your family relies on. Don’t switch something that ends up in the bin, because wasted food isn’t a saving.
Do supermarket loyalty prices make branded products cheaper?
Sometimes a member price brings a brand close to own-brand prices. Compare the unit price with the loyalty discount applied. My guide to supermarket loyalty apps explains when they’re worth using.
Is it cheaper to switch supermarkets instead?
It can be. Discount supermarkets are often cheapest overall, but travel and extra trips count too. Try downshifting at your usual shop first, then compare it with a trip to a discounter.
Should I downshift baby products and nappies?
Some families find own-brand nappies and wipes work well and save a lot over a year, while others prefer a particular brand. Try a small pack first. My nappies price guide compares options.
How do I get my family on board with cheaper brands?
Make it a game rather than a rule. Blind taste tests, letting children pick one swap to try each week and sharing what you saved can turn it into a fun family challenge.
I hope this gives you the confidence to try a few swaps this week. Start small, keep what you love and spend a little more on the things that really matter to you. For more ideas, see how to cut your grocery bill and how I spend less on groceries.
