I drive over to look after mum every day. My husband drives over to the food production business he runs in partnership with his father, who is over 70 and self-isolating. Nobody else lives or works on the premises. We would like to move into a currently unoccupied house on the business premises, to save travel and because in the next few weeks I will be needed there as well to help with the crop. The plan would be to leave our home and move there, but on the way there and back, I could call into our real house and have a shower and change of clothing, so I'd be reducing the risk. The doctor who have mum her diagnosis says this would be fine, but I can't find any official guidance. We'd be borrowing a van, but that would be left empty for 72 hours before my OH took it and moving a few basic items of furniture into the empty house. It would save so much driving back and forth and reducing the houses from 3 to 2.
