From May 2021,
"Details of the voter ID plans, set out by the Cabinet Office, show the range of possible photo ID types has been expanded from initial trials, where only passports, driving licences or ID cards were permitted, to include ID such as travel passes and blue badge disability parking permits.
A newly released UK-wide study, commissioned by the Cabinet Office, found that while 98% of adults possessed at least one of these types of ID, this fell to 96% where the photo was still definitely recognisable – a necessity for use in elections – meaning about 2.1 million people risked missing out."
I have no photo ID so I will need to apply for a "Voter Authority Certificate".
