i don't see why there should be a difference between meeting someone outside and meeting someone in your garden.
There is no indication when you can meet anyone in your house or stay over or have we got to wait until June? Pubs and restaurants are fully open in May. Can we have someone in then?
There is a document on the Gov.uk website setting it all out
Two households can meet outside from 12th April
Two households can meet indoors from 17 May
All restrictions lifted 21 June
