If you are volunteering please ask your organisation for an ID badge and a letter to explain why you're out and about.
Organisations please provide your key workers with ID and a letter of explanation.
See below for an example of what to include in a lettter thanks to Powys County Council for sharing.
"To whom it may concern, COVID-19 –
Keyworkers and travel for business I am writing to confirm that the holder of this letter is a keyworker of Powys County Council and is travelling for essential business reasons, in response to the pandemic. They are also carrying their ID badge should you need to view it. I would be grateful if you could please enable then to complete their journey to work.
Thank you for your assistance."
