Please do not contact us to provide risk assessments or letters for patients who are worried about the new government guidance and feel they should be exempt from wearing a face mask. Similarly, we will not provide letters of support for anyone who does not fall under the list of exemptions but considers them to have another reason to be exempted. GPs are not in a position to provide these.
Government advice on the use of face coverings can be found here: https://www.gov.uk/guidance/coronavirus-covid-19-safer-travel-guidance-for-passengers#exemptions-face-coverings. This link includes a list of reasons why someone might be exempt from wearing a face covering.
There is no requirement for evidence for exemption. Therefore it is sufficient for an individual to self-declare this.
