People who live alone in England and Northern Ireland will be able to form a support bubble with another household from Saturday, in a further easing of coronavirus lockdown rules.
Adults who live alone will be allowed to visit someone else's home and are even allowed to stay overnight.
In England, the rule also applies to single parents with children under 18.
It comes as charities warned about isolation, with the latest changes aimed at helping those who are lonely.
The new measures open up the possibility for grandparents who live alone to visit and hug their grandchildren for the first time since lockdown began.
Couples who live apart will also be able to be close to each other again.
It comes as the UK death toll rose by a further 181.
According to the latest figures, released on Saturday, 41,662 people who tested positive for coronavirus - across all settings - have now died.
The latest relaxation of the lockdown rules in England
was announced by Prime Minister Boris Johnson earlier this week.
A person's bubble can be with one other household of any size and close physical contact is allowed, meaning people in the bubble do not have to stay 2m apart.
But Mr Johnson said support bubbles must be exclusive, meaning someone can only form a bubble with one other household and they cannot swap.
If anyone in the bubble develops symptoms of coronavirus, then everyone in the bubble must self-isolate.
