England will face Serbia, Albania, Latvia and Andorra in 2026 World Cup qualifying, while Scotland could face Portugal or Denmark, Wales meet Belgium and Northern Ireland take on either Germany or Italy.
England were drawn in a five-team Group K, where Thomas Tuchel will take charge of the Three Lions against a Serbia side they beat in the Euro 2024 group stages under Gareth Southgate, thanks to a headed winner from Jude Bellingham.
England will also face Albania, who they beat across four meetings in qualifiers for the 2002 and 2022 World Cups, Latvia - who they have never played - and Andorra, who they beat by an aggregate score of 9-0 during 2022 World Cup qualifying.
England's first fixtures in this group will be at home, with Albania visiting on March 21, 2025 and Latvia three days later.
Scotland will play in a four-team Group C, featuring the team that loses the Nations League quarter-final between Portugal and Denmark, as well as Greece and Belarus.
Steve Clarke's side will also face Greece in March over two legs to decide if they stay in the top tier of the Nations League.
They kick off their World Cup qualifying campaign with trips to Portugal or Denmark on September 5, then Belarus three days later.
Wales were drawn in five-team Group J with Belgium, Macedonia, Kazakhstan and Liechtenstein.
Wales famously beat Belgium at Euro 2016, and will start their qualifying bid at home to Kazakhstan in March 2025, before facing North Macedonia away.
"It's a good group," said Wales head coach Craig Bellamy. "We're going to have to do our homework really well, and hopefully try and attack it and finish top of the group," he said.
Northern Ireland will play in the four-team Group A against the winner of Germany or Italy from their Nations League quarter-final, as well as Slovakia and Luxembourg. That group will begin in September 2025 with Michael O'Neil's side away to Luxembourg and Germany or Italy.
Republic of Ireland will also start their qualifying campaign in September and they have been drawn in the four-team Group F with the winner of the Portugal-Denmark Nations League quarter-final and opening opponents Hungary and Armenia.
Asked about facing Serbia and Albania, England boss Tuchel said: "They are always very talented individual players, a very emotional group, a very emotional crowd. So they can always surprise.
"We have to take this very seriously. It's a first fixture with Latvia, so a new challenge for all of us.
"And then we are clear favourites, of course, against Andorra, but qualification is key now. Qualification is top priority. We have to be serious. We have to be determined, and we have to show what we're up for in this group of five."
Tuchel was asked if he was confident of finishing top of the group, and replied: "I don't see it as a given. The gap closes more and more between the big nations and the small nations. You see it in the Euros lately.
"There are no such thing as results that are already done before the match is played. The smaller nations have become stronger and stronger. So we have to earn our place. We have to earn our top spot."
Scotland head coach Steve Clarke told Sky Sports News:
"I'm never one for looking too deep into draws - you just have to accept what you get and get on with it. It could have been worse, could have been better.
"[We face] a difficult pot one team - it doesn't matter if it's Portugal or Denmark. Greece we'll get to know very well over the next year because we play them twice in March [in the Nations League play-offs] and twice again later in the year.
"Belarus, I don't know too much about just now, but I'll make sure I do my homework and I'll know a lot more about them by the time we get to playing them.
"We're in a four-team group, we know what we have to do - finish first or second to qualify.
"For everyone connected with Scotland, we're desperate to get back to a World Cup. It was 1998 - a long time ago - I was still playing, so that was a long time ago!
"We want to get there. We appreciate the Tartan Army want to be there as well - they showed that in Germany in the summer - hopefully we can take them to USA, Mexico and Canada."

The 2026 FIFA men's World Cup takes place from June 11 to July 19, 2026.
The tournament will take place across 16 cities in three North American countries: the United States, Canada and Mexico. It is the first time a World Cup has been hosted by three nations.
The last time North America hosted the tournament was in 1994, when Brazil triumphed after beating Italy on penalties.
An expanded World Cup will feature 48 teams - 16 more than in Qatar 2022 - and take place across three host nations for the first time.
Only three teams so far are sure of their place at the finals: the hosts USA, Canada and Mexico.
The full fixture list with group games and kick-off times will only be available after the draw for the final tournament, which FIFA says is expected to take place towards the end of 2025.
But FIFA has already announced key dates and confirmed that the opening match will be held in Mexico City, with the final taking place at the New York New Jersey Stadium - home of the New York Giants and New York Jets.
Group stage: June 11-27 Round of 32: June 28 to July 3 Round of 16: July 4-7 Quarter-finals: July 9-11 Semi-finals: July 14-15 Third-place play-off ('Bronze final'): July 18 Final: July 19
