Our practice policy is that we will not be issuing letters to patients to exempt them from wearing face masks. The Government guidance suggests that there is no requirement for evidence of exemption. It should be sufficient for someone to declare that they are eligible for an exemption direct with the person questioning them (eg bus driver). Practices are therefore not required to provide letters of support for those who fall under the list of exemptions, or to those who do not fall under the list of exemptions.
