First in, first out: how to rotate your stock at home

By SGWNI. Checked on 2 November 2026.

To rotate your stock at home, keep the oldest food at the front, eat it first, and put anything new behind it. That’s all “first in, first out” means. It’s how shops keep their shelves, and it’s what stops a home stockpile quietly going out of date. Done this way, a stockpile isn’t extra food you never touch. It’s a slightly larger version of what you already eat.

Going out of date is a real worry. In the UK’s 2026 survey of how prepared people are, 25% said not wanting products to go out of date and be thrown away was a barrier to preparing. Rotation is the answer to that.

Start with food you already eat

Rotation only works if the food gets eaten. The Be Ready checklist says it’s best to buy food you’d usually eat, and that’s the most useful line on it. Tins you’d never choose on a normal Tuesday will sit at the back until their date passes.

So stock up on the things you already cook with, like the tomatoes, beans, pasta and rice that go into your normal meals. Then your weekly cooking does the rotating for you.

A setup that works in a normal kitchen

Take everything out of one cupboard. Check the dates as you go.
Group like with like. Tins with tins, and each type together, so you can see how much you have.
Put the soonest date at the front. New shopping goes behind it, even when that’s slightly more effort.
Make the date readable. Dates on tins can be small and hard to find. A marker pen on the lid means you can read them at a glance.
Use a shallow shelf if you can. Food gets lost in deep cupboards. If yours are deep, a box you can slide out does the same job.

If you have tins in more than one place, write down what’s where. Our stockpile inventory template is free to print or download.

Set a six-monthly check

Be Ready suggests setting a reminder every six months to check expiry dates and swap out anything that needs replacing, and to update your kit if your household’s needs have changed. Our rotation calendar makes a calendar file with those dates in it.

At each check:

Food. Move anything with a date in the next few months into your meal plan for the coming weeks.
Self-filled water. Replace it. Ready.gov and the CDC in the US both say every six months, and we know of no separate UK figure.
Bottled water. Follow the date on the bottle. UK bottled water usually has a best before of no more than 2 years.
Batteries, torch and radio. The British Red Cross suggests testing your torch and radio and recharging power banks.
Medicines. Check the dates, and leave enough time to reorder.
Baby and pet items. Children outgrow things, and diets change.
Grab bag. Anything packed away in a bag gets forgotten, so give it the same check.

What to do with food that’s close to its date

Eat it. A week with a few more tins in it costs you nothing and resets the clock when you replace them.

Past a best before date, food is usually still safe, though it may have lost some quality. Past a use-by date, it isn’t safe to eat. Best before and use by for a stockpile covers the difference.

If you’ve got more than you’ll get through, the Be Ready checklist suggests you could donate extras to people who may not have the means to prepare. Food banks have their own rules, so check first.

Where you keep it matters too

Rotation slows down waste, and good storage slows it further. US food safety guidance is the most specific we’ve found. It says to keep tinned food in a cool, dry place, and never above or beside the cooker, under the sink, or in a damp garage or basement. Heat is the main thing to avoid, because the risk of spoilage rises sharply as temperatures go up.

When a paper list stops being enough

A marker pen and a six-monthly check will do for most households, and you don’t need anything more to get started.

If you have a lot of stock, or it’s spread around the house, the harder part is remembering what’s about to go out of date. That’s what the Prep app is for. Each purchase is its own batch with its own date and location, it keeps a use first list, and it can remind you up to 90 days ahead.
