England won the second-half 33-0 as Ireland folded after a promising opening half when there was nothing between the sides.
The sides were level at 15-15 at the break, both having scored two tries.
A neat grubber down the right from Harry Byrne set up the opening try for Ireland after eight minutes, with Tommy O’Brien popping inside for James Hume to score.
Three minutes later English hit back via Ben Loader.
Ireland responded well with O’Brien scoring a try, with Byrne’s conversion making it 12-5 after 16 minutes.
It didn’t take Dingwall long to make amends and three minutes later a superb break from full-back Jordan Olowofela was finished by the Noerthampton Saints player. Tom Hardwick converted and then added a penalty after 25 minutes. It was 15-15 at the interval but it all went wrong for Ireland thereafter.
