The deadline for registration is on Tuesday.
More than 300,000 people in the UK, including over 200,000 under-35s, registered to vote in the general election on Friday.
The figures, released by the Cabinet Office, show that 308,000 registrations were recorded in the space of 24 hours, the vast majority of them online.
Among those signing up were 103,000 under-25s, 103,000 25-34 year-olds, 53,000 35-44 year-olds, 28,500 45-54 year-olds and around 20,000 over-54s.
It’s thought the large younger demographic that signed up could potentially be a boost for Labour.
“Yesterday Labour got behind National Voter Registration Day – unlike the Conservatives – because we want you to have a say in the future of our country,” Jeremy Corbyn posted on Twitter.
“And more than 300,000 people registered to vote. Make sure you can have your say on 12 December.”
It’s the second large surge in registrations in recent weeks after 139,162 and 177,105 applications were lodged on on two separate days at the end of October.
Voters will go to the polls on 12 December, in what will be the first Christmas election since 1932.
The deadline for registering to vote is 26 November.
