Westcombe Park toppled league leaders and local rivals Tonbridge Juddians in what was a convincing performance until the final five minutes of madness and mayhem.
In a close first-half the visitors, unbeaten so far this season, had the only score, a try by centre Tom Nicoll.
After the break Combe climbed back into the game as they dominated possession.
Two penalties by James Cameron got Combe on the scoreboard, then a try by Tom Gray and soon after one for winger Sam Randle opened up a healthy lead, 20-5, as both were converted by James Cameron.
Another penalty for Combe and with five minutes remaining the game should have been over.
But the hosts put themselves under pressure and let the visitors in for two quick tries, through Toby Martin and Lee Campion, and were relieved to hear the final whistle with the visitors still pressing for another score.
