I think you are best to ring the Chiropody clinic to see if your appointment is still on.
Most healthcare appts have been cancelled unless they are emergencies.
If your appointment is still on, I would query what measures they are taking to ensure the safety of patients and staff (personal protective equipment, door and chair hygiene, etc. etc.)
I got a letter from my local hospital cancelling a physio appointment in mid-April and asking me to contact them in July ‘if you still think you need the service’. The letter explained that all face to face appointments in the hospital were being cancelled.
