Atdhe Nuhiu and George Hirst both registered goals on the international stage on Friday evening.
The England Under-18s followed up their victory over Saudi Arabia in midweek with a 2-1 win over Qatar.
Hirst struck for the Three Lions after 15 minutes but the visitors were pegged back before the interval.
Tottenham Hotspur youngster Sam Shashoua scored what proved the winner.
Meanwhile, Nuhiu - on his first cap for Kosovo – marked the occasion by scoring his first senior international goal.
Trailing 2-0 at the break, Kosovo battled hard and halved the deficit when Nuhiu’s towering header had the beating of Iceland keeper Hannes Halldórsson.
The underdogs rallied late in the game but couldn’t find the equaliser they perhaps deserved.
Keiren Westwood was an unused substitute in the Republic of Ireland’s 0-0 draw with Wales, while Fraser Preston played 65 minutes of Scotland Under-19s' 1-0 defeat to Czech Republic.
