I see in the 'roadmap' it says that from 29 March the stay at home order will be lifted and travel outside local area will be allowed (it does say guidance will say stay at home if possible, but that's guidance not law).
It then says self-contained holiday accommodation will re-open from 12 April.
I'm assuming that second home owners, however, can go to their houses from 29 March? If you can legally travel, and you own the house and it's empty, that should be fine, right?
