- Many own-brand products come from the same factories as the big brands.
- Basics and store-cupboard staples are where own-brand wins outright.
- A handful of categories genuinely justify the brand — find your own list by testing.
The gap between a branded product and the supermarket’s own version is sometimes enormous and sometimes nonexistent. The problem is that you cannot tell from the packaging, which is designed precisely to imply a difference.
The only reliable method is to test, one product at a time, and keep a mental list of where it matters to you.
Understand the tiers
Most supermarkets run three or four levels:
- Value or essentials range — cheapest, plainest packaging, sometimes lower quality ingredients or different proportions.
- Standard own-brand — the workhorse, usually good, usually much cheaper than the brand.
- Premium own-brand — often genuinely excellent and still cheaper than the equivalent branded product.
- National brands — the most expensive, carrying advertising costs you are paying for.
The useful insight is that premium own-brand frequently beats the standard national brand on both quality and price. People skip it because it seems like a splurge, when it is usually the value option.
Who actually makes it
A significant proportion of own-brand goods are made by the same manufacturers who produce the branded equivalents, sometimes on the same lines with a different recipe or specification. This is not a secret, though contracts mean it is rarely advertised.
What you are frequently paying the brand premium for is marketing, not manufacturing.
Where own-brand almost always wins
These are the low-risk switches. Most people cannot distinguish them in use:
- Flour, sugar, salt, bicarbonate of soda — commodity ingredients with no meaningful variation.
- Tinned tomatoes, chickpeas, beans and pulses.
- Dried pasta and rice.
- Frozen vegetables and frozen fish.
- Milk, cream and butter.
- Bleach, washing-up liquid, kitchen roll and most cleaning products.
- Paracetamol, ibuprofen and other generic medicines — the active ingredient is identical and regulated, and the price difference is often startling.
- Basic toiletries such as cotton wool, plasters and shower gel.
Generic medicines deserve particular mention. A branded painkiller and a supermarket one containing the same dose of the same drug are pharmacologically equivalent. The price gap can be several hundred percent.
Where people more often notice a difference
This list is personal, and the point is to find your own. Commonly cited:
- Baked beans, tomato ketchup and other strongly flavoured store-cupboard items where the recipe is distinctive.
- Coffee, tea and chocolate, where sourcing and blend genuinely vary.
- Cereal, particularly ones with a distinctive texture.
- Nappies and some baby products, where performance differences are real and the cost of failure is high.
- Bin bags and cling film, where thickness and strength differ noticeably.
- Razor blades and some specific toiletries.
Even here, test rather than assume. Some own-brand versions in these categories are excellent.
How to run the test properly
- Switch one tier at a time. Going straight from the brand to the value range makes any difference obvious and puts you off the whole exercise. Standard own-brand first.
- Change a few items per shop, not everything at once. You will not know which change caused a complaint.
- Do not announce it to the household. Expectation drives a great deal of perceived difference. Decant it if the packaging is the giveaway.
- Keep a list. Where nobody noticed, that switch is now permanent. Where they did, go back.
Most households end up with a short list of maybe five or six items where the brand genuinely earns its price, and own-brand everywhere else.
Check the unit price anyway
Own-brand is usually cheaper, but not always — particularly when a brand is on a deep promotion. Compare price per kilogram every time rather than assuming. A branded product on offer sometimes beats the own-brand on price.
Read the ingredients if it matters
Where a cheaper version disappoints, the ingredients list usually explains why: less of the expensive component, more water, more filler. For products where that specific ingredient is the point — the meat content of a pie, the fruit content of a jam — it is worth comparing. For a bag of plain flour, it is not.
The realistic gain
Systematically downshifting where it does not matter, while keeping the few brands you genuinely prefer, typically cuts a grocery bill by a meaningful margin without any sense of going without. It is one of the least painful savings available, and it repeats every single week.
