The following people can provide childcare support in private homes and gardens:
registered childcare providers, including nannies
people in your support bubble
people in your childcare bubble
A childcare bubble is where someone in one household provides informal (unpaid and unregistered) childcare to a child aged 13 or under in another household. For any given childcare bubble, this must always be between the same 2 households.
Friends or family who do not live with you and are not part of a support or childcare bubble must not visit your home to help with childcare. Childcare bubbles are to be used to provide childcare only, and not for the purposes of different households mixing where they are otherwise not allowed to do so.
