Mould accelerated ahead of Johnny McEvoy (NFTO) and JLT team-mate Graham Briggs to take the victory - the 10th Tour Series win of his career.
With Briggs in third, Chris Lawless in fourth and Ed Clancy in eighth, JLT Condor once again took the team victory on the night to extend their leader further in the overall classification.
JLT Condor now sit 10 points ahead of second-placed Madison-Genesis as the series heads into its penultimate race in Croydon this evening – the route of which, incidentally, runs straight past the front door of Cycling Weekly's office.
Alice Barnes (Drops Cycling) headed up a clean sweep of the top three for Drops Cycling in round four of the Matrix Fitness Grand Prix.
Just as she did during Saturday evening's Mr Porter London Nocturne, Barnes accelerated away from the field to take a convincing solo victory.
Barnes's Drops Cycling team-mates Rebecca Durrell and Laura Massey placed second and third.
The result increases Drops Cycling's lead in the overall standings with two rounds remaining this week.
