After Saturday's 5-2 win over Manchester Storm at the MEN Arena, Knights followed up with a 4-2 victory against coach Kurt Kleinendorst's side on their home ice.
Knights are now three points clear at the top of the table after stretching their winning run to six matches, while the out-of-form Storm have now lost five of their last six league games.
The reigning champions were 4-0 down before the midway point of the game as London showed supreme confidence. Ryan Duthie and Mike Ware were on the scoresheet in the opening period, before Neal Martin and Jeff Hoad doubled London's advantage. Kelly Askew netted twice to give Manchester hope going into the last 20 minutes, but the Knights held on.
Ayr Scottish Eagles have moved up to fifth place following a 3-1 victory at Centrum over Cardiff Devils, who drop to seventh. The previous two games between these teams this season had ended in draws, but there was little chance of the hat-trick as Eagles sailed into a 3-0 lead in a penalty- strewn match. Two powerplay goals from their captain, Shawn Byram, in the first period was followed by a marker from Jamie Steer in the second, with Merv Priest scoring a scrappy consolation.
