Does this mean I can leave my home more?
No. All Londoners should continue to stay at home as much as possible.
Wearing a face covering does not change this advice. Face coverings are there as an added protection when you need to go into an enclosed space when you are unable to keep 2 metres away from others. More information about when you can leave your home.
You must always remember to wash your hands when you return home and avoid touching your face and eyes.
