We got off to a fine start, when after only five minutes Farleigh scored an own goal to put us 1-0 up. It was a hard-fought first half, but we increased our lead shortly before the break when the prolific George Baker fired home for 2-0.
We made a change at the break with Luke Guest replacing Aliba Matondo-Lando, and Jerome Eyoma was on for Manny Attakpah on 53 minutes.
The skipper fired us 3-0 up midway through the second half, to effectively seal the game, before he made way for George Thompson with seven minutes remaining.
It was 4-0 on 84 minutes when Baker added his second and a 92nd minute own goal sealed the 5-0 win.
With Battersea Ironsides surprisingly losing away at bottom placed Staines Lammas, we moved into top spot, two points clear of Battersea with both sides having seven games left.
Elsewhere, there were wins for Ripley Village, Royal Holloway Old Boys and Sheerwater, whilst Worcester Park won in the county cup.
