Guernsey eased their relegation fears with an 8-6 win at fifth-placed Hertford in National Three London.
Glen Walters' last-minute penalty secured just a second away win of the season for the island side.
Dave Davison had given them the perfect start with a try in the opening five minutes, the only score by either side before the half-time interval.
James Russell kicked two penalties for Hertford to put them ahead before Walters landed the match-winning kick.

Guernsey have spent the past three seasons in National Three London, having won in 2011 and 2012.
