Government guidance has been published to support volunteers and others to safely help vulnerable people during the coronavirus pandemic. Helping or providing care for a vulnerable person is one of only four reasons people are currently permitted to leave their homes, and this must always be done safely, including by minimising time spent outside of the home and ensuring you are two metres (six feet) apart from anyone outside your household.
