Jersey's defensive record has been praised by head coach Ben Harvey.
Jersey have not conceded a try in their last two matches and only let in four tries in their previous three games.
"We can rightly be proud of the fact that our defensive record is by far and away the best in the league and it's probably the best in the leagues around us as well," Harvey said.
"Our scramble defence is excellent and that's down to pride and belief in each other," he told BBC Radio Jersey.
Jersey have conceded fewer points than any team in the Championship, National One or either of the National Two leagues.
And, with games against sixth-placed Blackheath and leaders Ealing either side of Christmas, Harvey says his players want to keep their mean record intact and use it as a base from which to build a promotion push.
"The boys are very determined to maintain it going into the second half of the season. It's something that we feel is in our hands and hopefully go away and get promotion," Harvey added.
"Defence is about making sure you maintain a line and making sure that you work for each other.
"That element of pride is so important and the young men that we've got are working so hard for each other. There's a fantastic team spirit and that comes out in the defence."
