In July, Turkey and Italy agreed to combine their Euro 2032 bids, and Uefa has now given its approval.
Turkey submitted a bid to host both the 2028 and 2032 competitions, while Italy only submitted a bid for the 2032 event.
Both proposals still require formal clearance from Uefa at its executive committee meeting on Tuesday.
The five national organizations representing England, Scotland, Wales, Northern Ireland, and the Republic of Ireland said in a joint statement, "These are exciting times, and we have a very compelling Euro 2028 proposition for Uefa."
"Our bid will be groundbreaking for the men's Euros and leave a lasting legacy throughout the entire UK and Ireland," the bid's website states.
The presentations at that conference will play a significant role in the procedure by which the content of the bid proposals will be carefully considered before a decision is made, according to Uefa.
Turkey has never hosted a major international competition, however it did hold the June Champions League Final between Manchester City and Inter Milan at Istanbul's Ataturk Olympic Stadium.
Champions of Europe in reign The Stadio Olimpico in Rome served as the venue for Euro 2020, and Italy earlier hosted the tournament in 1968 and 1980.
Ten stadiums, including Glasgow's Hampden Park, Cardiff's Principality Stadium, Dublin's Aviva Stadium, and London's Wembley, were chosen for the UK and Republic of Ireland's candidacy in April.
The bid also includes Casement Park in Belfast and Bramley-Moore Dock in Everton, the latter of which is still being built while the former has already been completed.
Wales, Northern Ireland, and the Republic of Ireland have never played host to a major competition.
Along with Scotland, England was one of the 11 nations to host Euro 2020. It also served as the only host of World Cup 1966 and Euro 96.
An investigation into the chaos at the Euro 2020 final, which was played at Wembley in London, concluded that "ticketless, inebriated, and drugged-up thugs" may have even been able to kill someone when they invaded the stadium.
