Exemption cards
If you have an age, health or disability reason for not wearing a face covering:- you do not routinely need to show any written evidence of this
- you do not need show an exemption card
However, some people may feel more comfortable showing something that says they do not have to wear a face covering. This could be in the form of an exemption card, badge or even a home-made sign.
Carrying an exemption card or badge is a personal choice and is not required by law.
If you wish to use an exemption card or badge, you can download exemption card templates. You can then print these yourself or show them on a mobile device. Please note that the government is not able to provide physical exemption cards or badges.
