The visitors crossed through Steffan Emanuel who grounded Carwyn Leggatt-Jones' quick-thinking grubber after England's Luke Davidson had fumbled the ball in front of his own try line.
And in the final 10 minutes before the break they added six further points from penalties.
England 0-3 Wales
Halfway through the first half and Wales have controlled most of the possession and territory in very muddy conditions in Northampton.
They've only got three points to show for it mind after Carwyn Leggatt-Jones kicked an early penalty.
An early injury for Harlequins' Ollie Streeter has seen him replaced by Sonny Tonga'uiha.
