In Scotland, the sale of alcohol is regulated by the Licensing (Scotland) Act 2005. This act states that alcohol can be sold in licensed premises between the hours of 10am and 10pm on Sundays. However, there are some exceptions to this rule, such as for certain events and in certain places.
It is important to note that the sale of alcohol on Sundays is subject to local licensing conditions. This means that the exact hours and days when alcohol can be sold may vary from place to place. It is always best to check with the local licensing authority to find out the exact rules and regulations for your area.
