I’d never heard of it but Boots (who mightn’t be a nice as your local friendly pharmacist but do have a good website) tell me that it is available in some areas – you seem to need to talk to your GP who can advise on whether it is available locally http://www.boots.com/en/Pharmacy-Health/Prescription-Services/Minor-ailment-service/
That’s my new thing learned for the day, anything else is just a bonus.
