Does asda sell alcohol 24 hours a day?

It depends on the individual store. Each branch of Asda has its own alcohol licence (which is issued by the local authority where the store is located) that stipulates the times alcohol can be sold (and also times the shop may open to the public). Many Asda stores are permitted to sell alcohol 24 hours a day but some are not (some stores are permitted to open 24 hours a day, but are still not able to sell alcohol 24 hours).

Due to Sunday trading laws, large supermarkets in England & Wales are only allowed to open for 6 hours on Sunday, which means they can't stay open after 11:59PM on a Saturday night (so you won't be able to buy alcohol late at night on Saturday night/Sunday morning or Sunday night/Monday morning). Only small convenience stores/off licences can open 24 hours on Sunday.

Supermarkets in Scotland are allowed to open 24 hours a day, 7 days a week as there are no restrictions on shops opening 24 hours on Sundays in Scotland, however, shops are only allowed to sell alcohol from 10am - 10pm in Scotland.
