Organisers have also warned the 30,000 people who get tickets that they will need to confirm attendance by 5pm.
A statement on the British Summer Time website read: “Due to unprecedented public demand for the screening of Croatia vs England football match in Hyde Park, we are running a little later than usual in the dispatch of confirmation emails.

“However, thirty thousand lucky ballot winners will start to hear from us from 2pm this afternoon and will need to confirm their attendance before 5pm.”
Tickets for the screening became available through a ballot system open from 4pm on Monday, however many were disappointed when the ballot closed this morning after a series of technical glitches.
Ballot registration was extended to 8am on Tuesday however the website remained down throughout the night for some users wishing to try for tickets.
London Mayor Khan said earlier he was “thrilled” at the prospect of the screening, adding: “World Cup fever has gripped London and the rest of the nation and we have all been swept away by the fantastic exploits of Gareth Southgate’s team.
“Wednesday evening is a huge opportunity for our boys to do what many of us thought was impossible before the World Cup began and reach the Final.”
The game against Croatia is expected to attract tens of millions of viewers when it kicks off at 7pm on Wednesday.
