In fairness it says it's asked Sage when it will be safe, but it's in the phase 2 section which indicates to me this is their hope ....
In particular this has affected the isolated and vulnerable, and those who live alone. As restrictions continue, the Government is considering a range of options to reduce the most harmful social effects to make the measures more sustainable.
For example, the Government has asked SAGE to examine whether, when and how it can safely change the regulations to allow people to expand their household group to include one other household in the same exclusive group.29
The intention of this change would be to allow those who are isolated some more social contact, and to reduce the most harmful effects of the current social restrictions, while continuing to limit the risk of chains of transmission. It would also support some families to return to work by, for example, allowing two households to share childcare.30
