With both teams trying to move away from the bottom of the table, this match was always going to be close.
At half-time there was only one point between the teams. Tries from Donald Grieve and Fraser Harkness, with one conversion from Grieve, saw the hosts trail 12-13.
It was much of the same in the second half, with Jed taking the lead briefly before Biggar sealed the win.
Ross Combe scored a try for the hosts, with Daniel Ritchie converting and adding a penalty.
