Berkhamsted notched their sixth consecutive win on Tuesday night against a battling London Tigers side.
They made the perfect start by taking the lead in the fourth minute when a Josh Chamberlain corner was headed on by Ed Canham and Connor Calcutt was on hand to poke the ball in from close range
An impressive run by overlapping full back Dan Griggs was brought to a half when he was upended, with the home side awarded a penalty for the foul.
Visiting goalkeeper Jamie Adim tried to delay the kick and put his hand in the face of Chamberlain, who was waiting to take the penalty kick.
Adim was promptly sent off, but luckily for Tigers they had a keeper as a named substitute and Arlys Pampolim came on between the sticks and saved the spot kick.
A low shot from the recalled Adam Mead that slipped by the post was one of the few clear cut chances as the 10 men did well to hold on to the interval.
Yousef Slterefi had a chance to equalise when he was left clear after a Griggs miscue, but Carl Tasker made a great save.
Berkhamsted boss Micky Vipond decided to freshen things up bringing on Frankie Jowle, back from suspension, and James Towell and then gave a debut to James Bent, the former Leighton and Hemel player.
Jowle was soon in action on the end of a Towell cross.
The long overdue second goal came when Calcutt was played in by a fine through ball and he ran on to net his seventh goal in eight days with quarter of an hour remaining.
Towell was denied by a save after good work by Calcutt before Jowle created the third goal with a very inviting cross that Bent headed home powerfully to claim a goal on his debut.
The win moved Berko back up to fourth in the Premier division, with a game in hand on each of the top three teams.
On Saturday, internationals mean no Premier League games so it is Non-League Day and Berko are hoping it will boost the crowd for their home FA Vase tie with Hertford Town.
The old Berkhamsted Town club once reached the final at Villa Park of this prestigious national competition that is sponsored by Carlsberg. Everyone should be available to Mick Vipond for this important game.
Next Tuesday Berko have a home league game against Hillingdon Borough scheduled.
