The UK has entered its official shutdown, and the message from the government is that only shops selling essential goods can stay open. As of today (March 25), wine merchants and off-licences are included on that list.
The detail is spelled out here. Yesterday it seemed clear that any shop that principally selling alcohol should stay closed until restrictions are lifted, but today such shops find themselves classed as essential service providers.
Nobody will be allowed to sell drinks or food for consumption on the premises. But online sales and local deliveries are allowed and indeed “encouraged”.
