There is no requirement for the public to provide medical evidence for exemption from wearing face masks therefore a self- declaration should be sufficient.
We understand that some people will not be able to wear face masks due to a medical problem. However you do not need a note from us to confirm this. Please see the following guidance – which even supplies a link to print out your own exemption card if you wish.
For specific requirements in reference to public transport, shops or other areas where masks are required please contact those specific companies for further information.
Thank you for your cooperation.
