Ireland's John Lacey will referee his first ever RBS 6 Nations match in February, while Alain Rolland is also included in the Elite Panel in what is his last season.
Replacement flanker Joe Worsley sealed England's victory two minutes from time with their third try as the world and Six Nations champions bounced back from their Twickenham defeat last time out against Ireland.
Fly-half Olly Barkley landed six goalkicks out of seven on his full England debut to help restore his side's RBS Six Nations title hopes.
Wales managed two tries through Gareth Thomas and Mark Taylor with their other points coming from the boot of Stephen Jones but defeat meant their third loss in four Six Nations games this season. "It has been hard week. In the first half we played well but made a couple of mistakes," said Cohen.
"The key to it was keeping the ball and that was what we didn't do in the first half. It was good persistence and it paid off.
"I think everyone had something to prove. We all took the blame last week (after the defeat to Ireland) as it was not quite right. This week we trained hard and had a good look at ourselves."
After an early break by Wales centre Tom Shanklin, a late call-up in place of the injured Iestyn Harris, England took the lead in the sixth minute.
England full-back Jason Robinson's clearance kick set up a Wales lineout inside their own 22. But they failed to win clean possession and England scrum-half Matt Dawson launched an attack. The move was carried on by fit-again lock Danny Grewcock in one of several barnstorming first-half runs.
He fed centre Will Greenwood whose pass came to left wing Cohen who held off full-back Gareth Thomas and flanker Jonathan Thomas to just score in the corner having been narrowly denied a similar try against Ireland last time out.
Fly-half Barkley, making his first England start following Paul Grayson's calf injury, nailed the tricky conversion on a windswept afternoon and England were 7-0 up.
Their lead was soon reduced when Stephen Jones, from just inside his own half, landed a magnificent penalty - the first of three in the opening 40 minutes.
England, in marked contrast to the Ireland game, were winning their lineout ball while recalled flanker Chris Jones was putting in some crunching tackles.
Jones got Wales to within four points of England with his third penalty before Barkley, whose left-footed kicking style was reminiscent of injured World Cup hero Jonny Wilkinson, landed his fourth goal-kick out of four from 47 metres on the stroke of half-time to give England a 16-9 interval lead.
England lost Jones at half-time and soon saw their advantage reduced as well when two minutes into the period Wales exploited a three-man overlap with prop Duncan Jones sending in Gareth Thomas in at the right corner for a try which tied Ieuan Evans's Welsh record of 33.
Jones nailed the tough conversion and the game was level at 16-16. But soon afterwards he missed his first goalkick of the day when a penalty drifted narrowly wide.
But Wales, as they had done in their World Cup quarter-final defeat by England, were excelling in broken play with England's pack not retaining possession and setting up drive after drive.
And it was from just such a fragmented situation that Wales took the lead. England hooker Steve Thompson's sliced clearance kick set up a Welsh counter with wing Shane Williams bursting through the English cover before sending in centre Mark Taylor for a try.
Jones was again off target but at 21-16 Wales were ahead for the first time in the game.
England eventually regained their composure, as they had done in Brisbane, and started to build some pressure with Cohen denied a try yards from the line by desperate Welsh defence.
Wing Josh Lewsey went close with a scything run before he was hauled down but England's pressure told when Cohen got his second try from barely a foot out following a ruck in the 65th minute. Barkley converted and England were 23-21 up.
Entering the final 10 minutes England were encamped in Wales's 22 and the visitors defence cracked in the 72nd minute to give Barkley a simple penalty 10 metres out which made it 26-21 to the hosts.
Robinson's mesmeric run from deep inside his own half following the re-start took England into the Welsh 22 And then Worsley nailed England's victory with a close-range try. Barkley missed his first goalkick of the match but it made no difference.
