And we're off!
The race for votes is over, the race to count them is now under way.
A team of around 1,600 people will count the votes in Northern Ireland's 18 constituencies in three count centres.
It's first past the post so it's simple - the person at the top of the pile at the end of the first count wins and is elected, unless there is a recount.
There is no set time for counting to begin, the process gets under way as soon as ballot boxes get to the count centres.
Mid Ulster is expected to be the first to begin as it's on the doorstep of the Meadowbank Sports Arena in Magherafelt in Co Derry and counting could be under way within half an hour or so of the polls closing.
In contrast Fermanagh and South Tyrone, which is being counted in the same centre, may not get under way until midnight as it could take an hour and a half to two hours for ballot boxes to get there.
Unlike in Britain, there are no exit polls in Northern Ireland to provide a quick snapshot of the likely result.
But there won't be long to wait for the real thing.
The first Northern Ireland result is expected to be a race between North Down and Strangford, which both declared at around 1.50am in the last UK General Election in 2019.
North Down is a key contest where deputy Alliance Party leader Stephen Farry is in a real tussle to retain his seat.
Strangford will be watched closely by observers to gauge the strength of the Traditional Unionist Vote and the extent of the damage it does to the DUP.
The number of registered voters in Northern Ireland for this election is the highest ever, so more votes will mean more time to count and results this time around could be a little later.
Fermanagh and South Tyrone was the last seat to be declared in 2019, but the job was still completed shortly before 7am even with a recount.
It's also a key battleground and was the most marginal seat in the whole of the UK in 2019, with Sinn Féin winning by just 57 votes.
The result there this time could determine whether Sinn Féin emerges as the Northern Ireland party with the biggest number of seats at Westminster for the first time.
Six constituencies are being counted at the Titanic Exhibition Centre in Belfast, including the key battleground seats of East Belfast and North Down.
DUP leader Gavin Robinson is in a battle with Alliance leader Naomi Long to retain his seat in East Belfast and defeat would seriously undermine his position as party leader just over three months after replacing Jeffrey Donaldson.
There are four counts in South Lake Leisure Centre in Craigavon in Co Armagh with most focus on what happens in Lagan Valley, the seat of former DUP leader Jeffrey Donaldson who was forced to resign after being charged with serious sexual offences which he denies.
Back in Meadowbank, another key seat worth watching is South Antrim, where Ulster Unionist and former Stormont Health Minister Robin Swann is hoping to oust the DUP's Paul Girvan.
By the time most people are having breakfast, the Northern Ireland results should be complete.
Eighteen of the candidates will enjoy theirs more than the others.
