One goal settled Guernsey FC’s latest outing in the Isthmian South Central.
Hayes & Yeading are in the upper reaches of the league, and were rarely troubled by a Guernsey FC side missing the likes of Ross Allen, Matt Loaring and Charlton Gauvain.
The home side got their winner on 22 minutes, when a cross to the back post was cushioned across the goal for Jose Sani to tap home.
The result sees the Green Lions drop back into the relegation zone, one point adrift of South Park Reigate, who drew 3-3 with Binfield, but with two games in hand.
GFC travel to Farnham Town on Wednesday, before they play their last home game at Footes Lane against Ascot United before their move to Victoria Park.
