Centre Tom Stephenson was the only multiple scorer with the remaining six tries shared amongst the starting XV including one for Will Hooley, who opened the scoring en route to a 15-point haul.
The Senior Academy fly half crossed in the eighth minute after Lewis Hall provided the half break and it was on the left again that Howard Packman added a second just two minutes later, scorching over for the Saints' second seven-pointer of the afternoon.
Ulster were battling hard against the breeze to get out of their own half and while chances for Danny Hobbs and Josh Skelcey went begging, it was only a matter of time before the latter raced through.
Hooley maintained his perfect record from the tee with the extras and was successfully once more as Stephenson registered his first, muscling his way under the posts to finish off a move he had earlier initiated in midfield.
Ulster's first meaningful attack of the game came just before the break, but that ended with a knock on and after a change of ends back row Jack Allcock emphasised the gap, displaying an impressive turn of pace to make the most of a rapid counter from the Saints back three.
Hooley added the last of his five conversions but his contribution for the afternoon wasn't over. Having drawn two men into the tackle, Hooley freed his arms to release Stephenson and the visitors' defence proved powerless in stopping the England Under-18 man.
Oddly enough for Ulster, their first score of the game would come during a period with 14 men. The joy was short-lived, however, as Tom Collins showed his balance and sprinting capabilities to see off the Irish province's cover tight to the left hand touchline.
The extras were added by Sam Olver and like Hooley before him the Junior Academy 10 gave a glimpse of his playmaking abilities, producing a lovely offloading link with Tom Rhodes to put Alex Wootton through and away from a tired looking Ulster backline.
The winger's score put the finishing touches on a good all-round performances from Alan Dickens' side and left them in good form ahead of their next fixture, an East Midlands derby with Leicester at Franklin's Gardens on Saturday, September 15th.
