Berkhamsted finally returned to action after a prolonged break, but Mick Vipond’s side came away empty-handed from their trip to Hadley.
Having not played since January 28 as a result of the big freeze earlier this month, Berko were keen to get their season back on track.
However, Hadley goals either side of half-time put paid to the Comrades’ chances and gave the hosts all three points.
“I think overall they probably deserved it,” said Berko boss Vipond. “Second half they were the better side and we had a couple of scares before they scored. They had one or two decent players.
“If you want to win games in this division you have to play well for 90 minutes and we didn’t do that.”
Vipond was able to welcome Dale Sears back into the starting XI for Saturday after his ankle break in September.
Tyler Hatherley was also recalled following suspension in a strong looking Berko line-up, but it was Hadley who took the lead as Nick Chrysanthou slotted home in the 14th minute.
The lead did not last long though, with Berko’s Matt Wardle firing home his ninth goal of the season five minutes later to restore parity.
The third goal looked as though it would determine the outcome of the game, and it was Hadley who struck next to claim the win.
Mid-way through the second half, Dom Petrucci ran on to a through-ball and rounded Ed Farmer to bag the points for his side.
