Quick Answer
In the UK, Food Standards Scotland says a hard-boiled egg can be kept for up to two days in the fridge, with or without its shell. Some US agencies allow a week, but UK guidance is shorter. Keep boiled eggs chilled, count the days from boiling, and follow the date on any shop-bought pack.
Key Takeaways
- The shell does not change the UK limit. Food Standards Scotland gives the same two days for eggs in the shell or out of it.
- Search results are full of “one week” answers, but those come from US guidance. Check which country’s advice you are reading.
- Egg mayonnaise and sandwich fillings follow their own labels. Two shop-bought examples say two days and one day once opened.
How long can you keep boiled eggs in the refrigerator? What UK guidance says
How long can you keep boiled eggs in the refrigerator? Food Standards Scotland (FSS), the food safety body for Scotland, says on its egg safety page that a hard-boiled egg can be kept for up to two days in the fridge, within or outwith the shell. Renfrewshire Council’s egg safety guidance gives the same limit: if you are not planning to eat boiled eggs straight away, cool them quickly and keep them in the fridge for up to two days.
You will often see a week quoted instead. That figure is from United States guidance: the US Food and Drug Administration advises using hard-cooked eggs, in the shell or peeled, within one week after cooking. Advice differs by country, and Zenith follows the UK sources. We did not find a page from the Food Standards Agency (FSA, which covers England, Wales and Northern Ireland) that gives a specific limit for boiled eggs.

Shell on or peeled: how long can you keep hard-boiled eggs in the fridge?
On the UK guidance we found, there is no difference: the FSS figure covers eggs within or outwith the shell. Many websites, mostly non-UK, give different numbers for each, anything from a day or two for peeled eggs up to a week for eggs in the shell. They disagree with each other, so we have not used them.
Peeled eggs can dry out and pick up smells from other food, so keep them covered. That is a sensible precaution from general food storage advice, not a rule from the FSS.
Count the days from when you boiled the eggs, not from when you peeled them. That is our practical reading of the two-day limit.
Storing them well
Good storage is what makes the limit reliable.
- Cool and chill them promptly. The FSA’s advice is to cool cooked food quickly and put it in the fridge within one to two hours.
- Keep the fridge cold enough. The FSA says to keep the fridge at 5°C or below, checked with a thermometer.
- Cover them. Use a lidded container. British Lion eggs’ storage advice says to keep eggs away from strong-smelling foods, because shells are porous, and away from raw meat.
- Date the container. Write the day you boiled the eggs on it.
- How long can you keep a boiled egg in fridge conditions at the right temperature? Up to two days, counted from boiling.
- How long can boiled eggs keep in refrigerator conditions that are not cold enough? Less long. A warm fridge shortens the life of everything in it, which is why the thermometer matters.

Egg mayonnaise and sandwich fillings
Egg mayonnaise is where many people lose track. How long can you keep a boiled egg in refrigerator storage once it has been mashed with mayonnaise? Check the source.
Shop-bought fillings. One Morrisons egg mayonnaise sandwich filler says to keep it refrigerated and use it within 2 days of opening, and not to exceed the date shown. A Tesco boiled egg and salad cream snack pack says to consume it within 1 day of opening and by the use-by date, and that it is not suitable for freezing.
Homemade fillings. Several UK recipe sites say egg mayonnaise keeps for up to three days, covered, in the fridge. That is longer than the two-day FSS limit for boiled eggs. We suggest following the shorter limit. That is our interpretation, not an official rule for egg mayonnaise.
Mayonnaise made with raw egg. FSS says dishes made with raw or lightly cooked egg, including mayonnaise, are fine for most people if the risks are understood, but vulnerable groups (young children, pregnant women and elderly people) should only eat them if the eggs carry the British Lion mark or the Laid in Britain scheme. Otherwise they should eat eggs thoroughly cooked.
Smell and texture checks
Smell and texture are a weak test. Falkirk Council’s environmental health officers say you cannot see, taste or smell food poisoning bacteria, so an egg that looks and smells fine may still be past its date.
Commonly listed signs of spoilage are a slimy or chalky surface and a sulphurous smell. Those come from general food safety websites, not from the FSS or FSA. Bin the egg if you notice either. A greenish-grey ring around the yolk is usually caused by long boiling, as Healthline explains, and affects quality rather than safety.
If you are not sure how long an egg has been in the fridge, throw it away.
Can you freeze boiled eggs?
The UK guidance is limited here. FSS says hard-boiled egg yolks can be frozen. British Lion eggs say raw eggs can be frozen (beaten together if whole, or whites and yolks separately) for up to a year, though they recommend using them within four months. They say only fresh, in-date eggs should be frozen and that frozen eggs must be fully thawed and used only in thoroughly cooked dishes, never cooked from frozen.
For whole boiled eggs, guides from outside the UK say the whites turn tough and rubbery. We would not freeze them whole. If you want to freeze them, freeze the yolks only. Do not freeze shop-bought egg mayonnaise packs that say they are not suitable for freezing.
Frequently Asked Questions
How many days are hard-boiled eggs good for once cooked?
In the UK, up to two days in the fridge, according to Food Standards Scotland, with or without the shell. US agencies say a week. Count from the day you boiled them, keep them chilled and covered, and follow the date on any shop-bought pack.
How long does a hard-boiled egg last in the fridge?
Up to two days under FSS guidance. Renfrewshire Council gives the same limit. The US figure of one week does not apply to UK advice. If it is a shop-bought boiled egg product, follow its own use-by date and “once opened” instruction.
How long can hard boiled eggs keep in the refrigerator if they are peeled?
The FSS limit is the same for eggs within or outwith the shell: up to two days. Peeled eggs can dry out and absorb smells, so keep them covered. We found no UK guidance giving a different peeled limit.
How long does a hard boiled egg stay good?
In the fridge, up to two days under UK guidance. Keep it chilled promptly after cooking: the FSA advises getting cooked food into the fridge within one to two hours. If you cannot remember when it was boiled, throw it away.
How long do hard boiled eggs keep refrigerated in egg mayonnaise?
Check the label. One Morrisons filler says two days once opened, and one Tesco boiled egg snack pack says one day. For homemade egg mayonnaise, recipe sites say three days, but we suggest two, matching the boiled egg limit.
How long can boiled eggs stay in the refrigerator before freezing is better?
If you will not finish them within two days, freeze only the yolks, as FSS says yolks can be frozen. Guides from outside the UK say whole boiled eggs go rubbery when frozen, so we would not freeze them whole.
