A poor start led to Sevenoaks Town’s third successive Bostik League South East defeat at Salters Lane.
Town had a lot of possession but missed out in front of goal.
Frankie Sawyer and Luke Coleman both missed good first half chances, while Kenny Pogue headed another over the bar shortly before half-time.
Town conceded a third from a direct free-kick soon after the restart which put the result beyond doubt, Tom Ripley’s stoppage-time header proving to little too late.
Faversham made them pay dearly twice in the opening 11 minutes.
Keeper Ryan Nicholls, continuing in place of injured Ben Bridle-Card, punched away Dean Grant’s cross, only for home skipper Harry Goodger to crash home Faversham’s opener after seven minutes.
It was the same four minutes later. Three passes down the right sent Ryan Cooper running into the box for ex-Tunbridge Wells striker Jack Harris to score, punishing Town for failing to clear the ball twice.
Kenny Pogue set up Town’s first chance after 21 minutes, crossing from the right, Sawyer getting in front of a defender, but missing the target.
Another good move then saw skipper Bennett play-in Coleman but he failed to finish.
The visitors survived going 3-0 down early in the second half when Dan Carrington saw his effort bounce off the base of Nicholls’ left hand post, but another wasn’t long coming.
Greg Benbow earned a booking - one of four Town yellow cards - for bringing down Harris on the edge of the box- Goodger curling his free-kick wide of the wall and past Nicholls.
Sawyer’s low shot was then pushed away by former Town stopper Simon Overland.
Nicholls denied Harris the chance of a fourth, before Ripley pulled one back in the fourth minute of added time.
Jake McIntyre’s corner was cleared to sub Alec Fiddis whose shot bounced back to the defender and his chip into the box saw Ripley head home from five yards.
