The pair both became MPs for the first time in July. Sandher won Labour the constituency of Loughborough, while Jones claimed North East Derbyshire, over 30 miles (48km) apart.
Sandher does not see the distance being a problem.
"We are in London four days a week and then we have to go back to our constituencies so we have to be a little bit apart," he said.
"But I personally found it okay as there is a lot of stuff to do - this is a hard job."
For both, their shared understanding of the demands of politics has been a cornerstone of their relationship.
"I think we understand each other's lives incredibly well," Sandher said.
"If Louise was to say to me 'oh, look, we have to cut these plans because of this reason,' I would completely understand - and vice versa."
Combining forces has also made the job easier for Sandher.
"Louise is wonderful, so I just think she's better than me in every single way" including on learning the ropes of parliament, he said.
"You're also able to ask things of each other, some of that's the big stuff but some of the really small stuff which is like how do I fill in this admin form," Sandher said.
