Russell Brown, David Mundell and Michael Moore retained their seats
Three south of Scotland constituencies have returned the same MPs as the last general election.
David Mundell was set to remain the only Conservative MP in Scotland after winning Dumfriesshire, Clydesdale and Tweeddale.
In neighbouring Dumfries and Galloway, Labour's Russell Brown increased his majority to nearly 7,500.
Lib Dem Michael Moore also retained his Berwickshire, Roxburgh and Selkirk seat by a margin of close to 6,000 votes.
David Mundell increased his Dumfriesshire margin to more than 4,000 over Labour's Claudia Beamish.
Catriona Bhatia was third for the Lib Dems ahead of the SNP's Aileen Orr, Steven McKeane for UKIP and Green Party candidate Alis Ballance.
DUMFRIESSHIRE, CLYDESDALE AND TWEEDDALE - GENERAL ELECTION 2010
David Mundell (Con) 17,457
Claudia Beamish (Lab) 13,263
Catriona Bhatia (Lib Dem) 9,080
Aileen Orr (SNP) 4,945
Steven McKeane (UKIP) 637
Alis Ballance (Green) 510
Mr Mundell said he was delighted to see a rise in his majority on a night when the Labour vote had increased across Scotland.
"My pledge is to work for everyone in the constituency, always to put the constituency first and to help all constituents whether they voted for me on Thursday or not," he said.
Ms Beamish said it had been a "complex" campaign for the seat.
"I am determined to fight on with the Labour team and take more of the share of the vote and win the next time," she added.
For Ms Bhatia the result seemed to reflect the "status quo approach" across Scotland.
"We would have liked to have made more progress, of course everybody is in their campaign to win it, but I think we have put in a good performance and a great campaign," she said.
Ms Orr said she was "really pleased" to have got 1,000 extra votes.
DUMFRIES AND GALLOWAY - GENERAL ELECTION 2010
Russell Brown (Lab) 23,950
Peter Duncan (Con) 16,501
Andrew Wood (SNP) 6,419
Richard Brodie (Lib Dem) 4,608
Bill Wright (UKIP) 695
She said an economic "fear factor" appeared to have caused a UK trend towards the Conservative and Labour parties.
For the Greens, Ms Ballance said she believed the party had got its message across to voters.
There was also a rise in the vote for Labour's Russell Brown in Dumfries and Galloway.
Tory Peter Duncan was second, with the SNP's Andrew Wood third. Lib Dem Richard Brodie finished fourth, ahead of UKIP's Bill Wright.
Mr Brown admitted he "really did not expect" such a large increase in his majority.
"I think it's down to the hard work that we have put in but it really is an astounding majority," he said.
For the Tories, Mr Duncan said he was "really disappointed" by a result which appeared to be "replicated across Scotland".
"I don't think that's good news for Scotland but it's what happened and we have to reflect on it and do what we can to reverse it," he added.
Mr Wood said it was a "missed opportunity" for people to switch away from the two main parties but hoped it would see a hung Parliament.
BERWICKSHIRE, ROXBURGH AND SELKIRK - GENERAL ELECTION 2010
Michael Moore (Lib Dem) 22,230
John Lamont (Con) 16,555
Ian Miller (Lab) 5,003
Paul Wheelhouse (SNP) 4,497
Sherry Fowler (UKIP) 595
Chris Black (Jacobite) 134
"If you can have parties working as well as they are in the Scottish Parliament then I don't see any reason why we shouldn't have it in Westminster," he said.
A "good campaign" was how Mr Brodie described the Lib Dem effort in the seat.
"We were hopeful we would do better but it sort of represents what has happened across the country," he said.
The majority remained almost unchanged for Lib Dem Michael Moore in Berwickshire over Tory John Lamont.
Labour's Ian Miller was third in front of Paul Wheelhouse of the SNP, Sherry Fowler of UKIP and the Scottish Jacobite's Chris Black.
Mr Moore called it a "clear cut" result which he was delighted with.
He said people had looked not only at his own record but also what his party wanted to achieve over the next five years.
Mr Lamont said the Tory vote had increased steadily in the constituency.
He said he believed the result showed there had been "tactical voting" between other parties in order to keep the Conservatives out.
