Lactose-free semi-skimmed cow’s milk is an option if you want to keep drinking dairy milk while managing how much you consume: compare the energy figure on the carton and the amount you usually pour. Fresh and long-life Arla LactoFREE semi-skimmed products list 38 and 39 kcal per 100 g respectively, so storage and how quickly you use a carton may matter more to your choice than that difference. If you need to avoid milk proteins, choose a suitable milk-free drink instead; lactose-free dairy milk still contains milk.
If you want to keep using cow’s milk in drinks or meals, lactose-free dairy milk lets you compare familiar milk formats. Its energy contribution still depends on the carton and how much you use. The NHS distinguishes lactose intolerance from a milk allergy.
Compare energy and fat on the exact lactose-free carton rather than assuming the lactose-free label means fewer calories. Arla UK, Tesco, Sainsbury’s and M&S publish nutrition figures for their semi-skimmed options, though some label values per 100 g and others per 100 ml.
A long-life carton may suit cupboard storage before opening. Arla UK says its long-life semi-skimmed milk should be refrigerated after opening and consumed within three days, so consider how quickly you will finish it.
Decide whether you want lactose-free cow’s milk or a milk-free drink, then compare the nutrition, flavour and storage details of the cartons you would actually use.
| Priority | What to check | Your needs |
|---|---|---|
| Milk suitability | Read the ingredients and allergen declaration. Lactose-free cow’s milk still contains milk; check a milk-free drink’s ingredients and allergens separately. | I want to avoid lactose but keep dairy milk, or I need a drink that does not contain milk. Those are different requirements: the NHS distinguishes lactose intolerance from milk allergy. |
| Energy and portions | Compare energy using the stated basis, whether per 100 ml or per 100 g, and consider your usual pour. Arla UK lists 38 kcal per 100 g for its fresh semi-skimmed milk and 39 kcal per 100 g for its long-life version. | Milk goes into my drinks, cereal or recipes, so the amount I use matters as well as the carton’s energy figure. |
| Milk type and nutrition | Check the skimmed or semi-skimmed variant and its energy, fat and protein panel. If calcium matters to your comparison, check its declaration on the exact carton or milk-free drink. | I may prefer skimmed milk, but I want to compare its actual label with semi-skimmed milk rather than assume every variant has the same nutrition. |
| Flavour and use | Check whether the product is cow’s milk, soya or almond, and whether its described flavour suits the drinks or recipes you make. A description such as “mild” is not a comparable taste measurement. | I want something I will use in tea, cereal or cooking, without treating a flavour description as a guarantee that I will like it. |
| Storage | Check whether the carton is fresh or long-life, its storage instructions before opening and its use-by guidance after opening. Arla UK advises using both its fresh and long-life semi-skimmed products within three days of opening. | If I only use a little at a time, unopened storage and the time available to finish an open carton affect which format suits me. |
Lactose-free cow’s milk still contains milk. The NHS distinguishes lactose intolerance from milk allergy, and Arla UK and M&S warn that their lactose-free dairy products are not suitable for people with a milk allergy.

Compare the label’s measurement basis and your usual portion before changing cartons solely for their energy figures.
Long-life storage before opening does not remove the need to refrigerate the carton afterwards. Arla UK advises consuming its fresh and long-life semi-skimmed products within three days of opening.
Choose a format and pack size you expect to use within the instructions on its carton.
An opened carton that cannot be finished in time may be wasted.
Recipes and retailer availability can change, affecting an ingredient check or a planned grocery order.

Not necessarily: “lactose free” describes lactose content, not an energy advantage. For example, Arla UK lists 38 kcal per 100 g for its fresh semi-skimmed LactoFREE milk, while Tesco Groceries lists 41 kcal per 100 ml for its lactose-free semi-skimmed dairy drink. Check the measurement basis and the amount you use.
Choose by how you plan to store and use it.
