18:28 BST - That brings an end to our coverage of the Championship play-off final.
Massive congratulations to Hull and commiserations to Middlesbrough following a breathless end to a tense encounter.
18:17 BST - Hull stands to earn at least £200 million over the next three seasons as a result of their promotion to the Premier League, according to finance experts Deloitte.
The figure could rise to around £365 million if the club survives their first season in the top flight.
A handsome day's work for the Tigers.
18:12 BST - Hull head coach Sergej Jakirovic speaking to Sky Sports:
"It's an amazing feeling. I still can't believe we did it because we suffered a lot all game.
"The regular season was over and this was like starting a completely new tournament, no matter how many points you had.
"It's about pressure. In the regular season, you have time to fix everything."
17:47 BST - The Hull players are making their way up the fabled Wembley steps to collect the play-off trophy after a gutsy performance in the London heat.
Captain Lewie Coyle hoists the cup, Oli McBurnie grabs it off him after, then it's handed to a beaming head coach Sergej Jakirovic.
17:46 BST - Hull striker and game winner Oli McBurnie speaking to Sky Sports:
"For the first time ever, I think I'm speechless!
"It's been a long, hard season and that game today summed us up. We knew we weren't going to come in and have all of the ball - I don't think we've won a game this year when we've had more of the ball than the opposition.
"It was tough out there with the heat and Middlesbrough are a top, top team. We knew we were going to be right up against it, but we felt we'd have one chance and it was written for me to get it."
17:43 BST - It is a truly incredible story for Hull, who only survived last season on goal difference.
They were placed under a transfer embargo across both transfer windows, severely restricting who they could bring in.
Yet here they are today, Premier League-bound.
17:39 BST - The tale of the tape this afternoon.
17:36 BST - Read the match report from a dramatic finale at Wembley:
Late drama as Hull reach Premier League with play-off win over Middlesbrough
17:34 BST - FULL-TIME! HULL ARE PROMOTED TO THE PREMIER LEAGUE!
The Tigers have done it! Oli McBurnie is the hero on the big stage, capitalising on Sol Brynn's error to send Hull back to the top flight.
Major play-off heartbreak for Middlesbrough, on the flip side.
17:25 BST - GOAL! UNBELIEVABLE! Hull take the lead in the 95th minute and Oli McBurnie could be the hero!
He slams in at the death after goalkeeper Sol Brynn agonisingly mishandles a cross.
He rips his shirt off in celebration and Hull are moments away from reaching the Premier League!
17:11 BST - CLOSE! Middlesbrough substitute Sontje Hansen finds space at a tight angle in the box, but Ivor Pandur makes the save and the ball trickles wide.
The linesman did raise his flag for offside, though.
16:59 BST - Another drinks break and the atmosphere increases from the Middlesbrough side of Wembley as they spot local boy Hayden Hackney getting ready to come on.
He hasn't played any minutes since mid-March, but could he be the one to spark this into life?
16:33 BST - Back underway at Wembley.
16:21 BST - HALF-TIME! Hull 0-0 Middlesbrough
Hull's Oli McBurnie has come the closest to opening the scoring with his header hitting the crossbar, but it has been cagey overall.
16:19 BST - Now it's Middlesbrough's turn to come close as David Strelec's strike from distance whistles just past the post.
The game has picked up just as the half is coming to an end.
16:16 BST - CROSSBAR! Hull are close to an opener as Oli McBurnie's deflected header clips the bar shortly before the break.
15:56 BST - Time for an enforced drinks break as we reach the 25-minute mark.
Several players have draped wet cooling towels over their heads to combat the heat.
15:46 BST - Middlesbrough have settled nicely in the first 15 minutes, having just over 75 per cent of possession.
We're still waiting for the first real opportunity to present itself.
15:30 BST - KICK-OFF! Will it be Hull or will it be Middlesbrough to clinch a spot in the Premier League?

15:28 BST - National anthem time. 'God save the King' is belted out and ends with a roar around Wembley. Kick-off is moments away...
15:15 BST - It's a bit of a scorcher today with temperatures set to peak at 29°C at Wembley.
It will be a bit hotter down at pitchside, however, as the sun drenches the cauldron.
14:30 BST - It's getting real now. Here are the confirmed Hull and Middlesbrough lineups to play in football's richest game:
14:05 BST - The 'Spygate' furore continues as Hull owner Acun Ilicali has vowed the club will take legal action if they fail to win today's Championship play-off final.
Ilicali told the BBC that Middlesbrough being reinstated is "unbelievable" and an "incredibly wrong decision".
"Our legal team says that we have to go for action, that's for sure," Ilicali said.
"So we have no doubt about it. Here, all we want is justice. If justice is broken, nobody will enjoy football."
13:35 BST - Just one match separates both Hull and Middlesbrough from a return to the Premier League for the first time since 2017.
Boro were in an automatic promotion spot behind Coventry for most of the season, but dropped to fifth after a patchy final few games.
Hull finished sixth and seven points behind Middlesbrough on the final day of the Championship to sneak into the play-offs.
13:19 BST - Middlesbrough were actually beaten by Southampton 2-1 on aggregate in the play-off semi-finals before the Saints were banished.
Southampton's late appeal was rejected after Middlesbrough were reinstated, while manager Tonda Eckert is said to have authorised club staff to covertly watch opponents' training sessions.

13:00 BST - Good afternoon! Welcome to Flashscore's coverage of the Championship play-off final as Hull and Middlesbrough battle for a spot in the Premier League under the famous Wembley arch.
The showpiece has been overshadowed by 'Spygate', which saw Middlesbrough reinstated despite losing their semi-final to Southampton, who were expelled for spying on a Boro training session.
The focus is on the football at 15:30 BST, though, but we suspect this will rumble on for a while...
