Households changing the milk adults use
If milk goes into cereal, drinks and cooking throughout the week, compare lower-fat grades as well as how quickly an opened pack is used. The NHS advises lower-fat milk for older children and adults.
Who needs to make this choice?
Families with children of different ages
One milk grade may not suit every use in a mixed-age household. The NHS says 1% and skimmed milk should not be given as a main drink to children under 5, so check who will drink each pack before changing the family shop.
Households that open milk at an irregular pace
A filtered pack’s stated opened-life may be useful when a standard fresh bottle is not finished promptly. Compare the instructions on the exact packs and allow enough refrigerated space for anything that needs chilling.
What should you check before buying?
Start with who will drink the milk, then choose a fat grade and pack format that fit the household’s use and storage.
| Priority | What to check | Your needs |
|---|---|---|
| Fat grade | Compare fat and saturates on the same label basis, such as per 100ml. Check other declared nutrients on the exact pack if those matter to your comparison. | I want to compare lower-fat milk with the whole milk we usually buy, rather than assume every semi-skimmed or skimmed product has the same label values. The NHS advises lower-fat milk for older children and adults. |
| Children’s ages | Check whether 1% or skimmed milk would be a child’s main drink. The NHS says neither should be used as a main drink for children under 5. | If younger children and adults drink milk at home, I need to decide which pack is for whom instead of switching every drink to the same grade. |
| Pack format | Check the volume of each bottle or carton and how many will be opened at once. A 2L bottle, a 2.272L four-pint bottle and six separate 1-litre cartons involve different opening patterns. | We use milk regularly, but I want the amount opened at one time to match what we can finish under the pack’s instructions. |
| Storage and opened-life | Read the exact pack’s refrigeration and after-opening directions. Tesco’s named fresh semi-skimmed pack says best within 5 days once opened; Arla Cravendale states 7 days for its filtered 2L pack when stored at 0°C to 5°C. | Milk use varies across the week, so I need to check both fridge space and whether we can follow the opened-life instruction for the pack we choose. |
What can go wrong with a large milk shop?
-
Changing everyone to 1% or skimmed milk
That change overlooks the NHS advice not to give either grade as a main drink to children under 5.
Check who uses the milk for drinks before changing the household’s packs. A mixed-age family may need to keep different milk grades for different members.
-
Choosing a large bottle without checking when it must be used
Opened-life instructions differ even among semi-skimmed products. Marks & Spencer says its named four-pint pack is best consumed within 3 days of opening, Tesco says 5 days for its named four-pint pack, and Arla Cravendale states 7 days for its filtered 2L pack under its refrigerated-storage instructions.
Plan how much will be used after opening, then follow the storage and opened-life directions on the bottle actually bought.

Common questions
Should a large family replace all its whole milk with semi-skimmed?
Not automatically. The NHS advises lower-fat milk for older children and adults, but a household choice also needs to account for each child’s age and how the milk is used. In particular, the NHS says 1% and skimmed milk should not be main drinks for children under 5.
Is semi-skimmed the only lower-fat grade to consider?
No. The NHS also discusses 1% and skimmed milk as lower-fat choices for older children and adults. Compare the labels and consider who will use each pack; neither 1% nor skimmed milk should be a main drink for a child under 5.
When might filtered semi-skimmed milk suit a large shop?
It is worth considering when milk is opened irregularly and the household can follow the product’s storage instructions. Arla states that its Cravendale 2L filtered semi-skimmed milk lasts up to 3 weeks unopened and 7 days after opening at 0°C to 5°C. Compare those directions with the exact fresh pack you would otherwise buy.
How long can an opened bottle of fresh milk be kept?
Follow the instruction on that bottle, because the stated periods differ. Tesco Groceries says its named four-pint semi-skimmed pack is best within 5 days once opened, Marks & Spencer says within 3 days for its named four-pint pack, and Arla states 7 days for its Cravendale filtered 2L pack when stored at 0°C to 5°C.
