Vegan guests
Choose a drink labelled suitable for vegans for serving or baking, and check the other ingredients in cakes, icing and decorations. The Vegan Society’s definition of a vegan diet excludes dairy.
Who are you serving?
Guests avoiding lactose
Lactose-free cow’s milk may be an option if the guest can consume dairy. Arla UK lists whole milk and lactase enzyme in its LactoFREE Whole Milk Drink, so the lactose-free label does not mean milk-free.
Guests with cow’s-milk allergy
Make an allergy-aware plan with the guest or their parent or carer before choosing ingredients. Gloucestershire Hospitals NHS Foundation Trust distinguishes milk allergy from lactose intolerance and advises avoiding milk products with a milk allergy; keep packaging available so the exact ingredients and allergen information can be checked.
What should you check before buying?
Start with each guest’s requirement, then check the exact drink and every other ingredient used in the food you plan to serve.
| Priority | What to check | Your needs |
|---|---|---|
| Vegan suitability | Check that the individual drink is labelled suitable for vegans. Check cake, icing, chocolate and decorations separately; lactose-free dairy milk still contains milk. | I’m serving vegan guests, so both the drink and anything made with it need to avoid animal-derived ingredients. |
| Lactose or milk allergy | Ask which requirement applies. Arla UK lists milk in its lactose-free whole drink; Gloucestershire Hospitals NHS Foundation Trust advises avoiding milk products with a milk allergy. | A guest avoiding lactose may be able to have dairy, but I must not treat that as permission to serve dairy to someone with milk allergy. |
| Other allergens | Check the exact pack’s ingredients and precautionary allergen statement. Plant drinks can contain ingredients such as soya or almonds; vegan wording alone does not settle allergy suitability. | If anyone has a declared allergy, I need an option that fits their particular requirements, not just one marked vegan. |
| Party preparation | Confirm what guests or carers can have before shopping. Keep original packs available and clearly identify prepared food and separate drink options to help avoid mix-ups. | I want guests to be able to identify what is in a drink or cupcake, especially when several options are being served. |
Party-shopping mistakes to avoid
-
Assuming lactose-free means vegan
Lactose-free dairy milk still contains cow’s milk. It does not meet a vegan requirement and must not be offered as a milk-free option to someone with milk allergy.
Choose a drink labelled suitable for vegans for vegan guests. Consider lactose-free dairy milk only after confirming that the guest can consume dairy.
-
Using a vegan claim as an allergy check
A vegan claim does not establish whether cross-contact with an allergen is relevant to a particular guest.
Read the exact pack’s ingredients and precautionary allergen statement, and follow the guest’s or carer’s guidance.
-
Choosing a plant drink without checking its base
A soya or almond drink may meet a vegan requirement while containing an ingredient another guest must avoid.
Ask about other allergies before choosing the plant base, then check the individual product’s allergen information.
-
Discarding packaging before serving
Without the original pack, guests and carers cannot readily check the ingredients and allergen information for the product used.
Keep packs available, identify prepared food clearly and plan how separate options will be served when allergies are declared.

Frequently asked questions
Is lactose-free milk vegan?
Lactose-free dairy milk is not vegan: it remains cow’s milk even when lactase is used to break down lactose. For vegan guests, choose a drink labelled suitable for vegans and check the other party-food ingredients too.
Can someone with cow’s-milk allergy have lactose-free dairy milk?
No. Gloucestershire Hospitals NHS Foundation Trust advises avoiding milk products with a milk allergy, and lactose-free dairy drinks such as Arla LactoFREE Whole Milk Drink still declare milk. Ask the guest or their carer about their specific requirements before choosing an alternative.
Is a vegan drink automatically suitable for someone with milk allergy?
No. Vegan suitability and allergy suitability are different checks; cross-contact may be relevant. Read the exact pack’s ingredients and precautionary allergen statement, then follow the guest’s individual allergy guidance.
What should I ask guests before buying drinks and baking ingredients?
Ask whether they need vegan food, avoid lactose or have a declared allergy, including to milk, soya or nuts. For an allergy, discuss the specific ingredients and serving plan with the guest or their parent or carer before shopping, as Anaphylaxis UK advises for food events.
Can I use a plant drink in vegan birthday cupcakes?
Yes, if the whole recipe and its ingredients suit the intended guests. Tesco Recipes’ dairy- and egg-free vanilla cupcakes use soya milk, but soya is not suitable for someone who must avoid it; check all ingredients and the finished decorations.
