Choose lactose-free cow's milk if lactose is the concern and cow's-milk protein is tolerated: it is still dairy milk and is unsuitable for a milk allergy. If milk must be avoided, choose a dairy-free drink and check the exact pack's allergens and ingredients. For a regular dairy replacement, consider an unsweetened, calcium-fortified plant drink, then match the carton size and storage instructions to your household's use.
If you want cow's-milk-based milk for tea, cereal or cooking, lactose-free dairy milk is an option when milk protein is tolerated. Gloucestershire Hospitals NHS Foundation Trust distinguishes lactose intolerance from cow's-milk allergy.
Choose a genuinely dairy-free drink if milk must be avoided or you prefer a plant-based option. Check the current pack's allergen statement; for regular dairy replacement, the NHS identifies unsweetened, calcium-fortified plant alternatives as an option within the dairy-and-alternatives food group.
Match pack size and chilled or long-life format to how quickly you use each carton. Check the storage instructions before and after opening, particularly if fridge space is limited.
Consider it: When lactose is the issue but cow's-milk protein is tolerated and you want to keep using dairy milk.
Bear in mind: It still contains milk; the cited Arla Lactofree and M&S products warn that they are unsuitable for people with a milk allergy.
Consider it: When cow's milk must be avoided or a plant-based drink fits your household's preferences.
Bear in mind: Ingredients, allergens and nutrition vary by product, so a dairy-free label alone does not settle which carton to buy.
| Priority | What to check | Your needs |
|---|---|---|
| Milk and allergens | Check whether the drink contains cow's milk and read the exact pack's ingredients and allergen statement. Lactose-free dairy milk is not dairy-free. | I need to know whether I am avoiding lactose or milk itself before choosing a carton. |
| Regular replacement | For plant drinks used regularly instead of dairy, check whether the product is unsweetened and calcium-fortified. Compare the nutrition panels on the cartons you are considering. | If I regularly replace dairy, I want to check the drink's fortification and its sugar, fat and protein declarations rather than rely on the word “plant-based”. |
| Everyday uses | Check the product's stated uses if you need it for cereal, cooking or hot drinks. A barista variant may be aimed particularly at coffee. | Will the same carton cover the drinks and meals we make during the week, or do we need a separate coffee option? |
| Carton and storage | Compare carton size, chilled or long-life format, and instructions for storage after opening. Waitrose's cited Arla product and M&S's cited lactose-free product both say to consume within three days of opening. | Our cartons need to fit in the fridge and be used within the time stated on each pack. |
Lactose-free cow's milk remains a milk product. Gloucestershire Hospitals NHS Foundation Trust says milk products must be avoided with a cow's-milk allergy.

The cited Arla Lactofree and M&S lactose-free dairy products call for refrigeration and consumption within three days of opening.
Choose a carton size that matches use between shops, and follow the instructions on each pack.
