Other local media have also been up all night with the Hertfordshire Mercury reflecting everything in its live results page.
In St Albans, Liberal Democrat Daisy Cooper told the Herts Advertiser it was "an absolute honour" to be elected MP after she unseated Conservative Ann Main to become the city's first Lib Dem MP.
In the Watford Observer, the town's new MP Dean Russell, who held the seat for the Conservatives, said he would be "building on an amazing legacy of Richard Harrington", the man he replaced and that his win was "a vindication of what our Prime Minister wants nationally".
The Comet which covers Hitchin and Stevenage focuses on Bim Afolami holding the Hitchin and Harpenden seat with him declaring it was "a demonstration of the strength of democracy".
In the Welwyn Hatfield Times, transport secretary Grant Shapps said that "it's fantastic the country can move on from Brexit" as he held his seat.
There are four new MPs in Hertfordshire, but only one represents a change of party:
Dean Russell has been elected MP for Watford, meaning that the Conservative Party holds the seat with an increased majority.
The new MP beat Labour's Chris Ostrowski by 4,433 votes. This was more than double Richard Harrington’s 2,092 vote majority in the 2017 general election.
Ian Stotesbury of the Liberal Democrats came third and Michael McGetrick of the Social Democratic Party came fourth.
Voter turnout was up by 1.9 percentage points since the last general election.
More than 58,000 people, 69.7% of those eligible to vote, went to polling stations across the area on Thursday, in the first December general election since 1923.
One of the four candidates, Michael McGetrick (Social Democratic Party) lost his £500 deposit after failing to win 5% of the vote.

Hertfordshire has 11 constituencies and until September they were all Conservative.
However, the MP for South West Herts David Gauke (pictured), lost his place in the party over his Brexit views, but still has stood as an Independent against his old party.
The Liberal Democrats fancies its chances of taking St Albans, despite Tory MP Anne Main’s 6,000 majority, whilst Watford could be close too. It’s a Tory seat currently, but with a 2,000 majority from Labour, and the standing MP Richard Harrington not seeking re-election.
Hertford and Stortford gets a new MP, following Mark Prisk’s retirement, and Labour and the Lib Dems are also targeting Stevenage. The other six seats are likely to remain Tory.

Lawyers for parents fighting to keep a Hertfordshire centre for disabled children open say they've been given a reprieve.
Alex Rook, from Irwin Mitchell, told the BBC: "I am delighted to say that the CCG (clinical commissioning group) has agreed to set aside its decision to cease funding respite services at Nascot Lawn.
"They have confirmed that they will consult with the families of children and young people before thinking again about the matter."
Nascot Lawn Respite Centre in Watford was due to close in October, but that date has been pushed back to January.
We have yet to hear from Hertfordshire CCG, but when the decision was first made it said the closure of the centre was necessary because of its "serious financial situation", and that the focus must be on spending on services it had a legal duty to provide.
The decision comes ahead of a planned judicial review next week, where health executives were being taken to the High Court for failing to consult with the families.
Watford MP Richard Harrington said: "Although this is very welcome news, there is more work to be done to protect this service for our local community. I want to see a long-term solution and that's what I will be working towards over the coming months."
Mark Watkin, Lib Dem councillor, said the move was "cynical".
