It was the third win of the season for coach Chris Davey and his team, following those over New Zealand and Italy, while England had gained a 26-25 win over France at Newbury last week.
It was 16-6 at the interval with wing Matthew Nuthall (Pontypridd) scoring a try and fly half Nick Robinson (Cardiff) converting and placing a hat-trick of penalty goals against two penalties by England fly half Warren Spragg (Sale).
While Spragg kicked a third penalty, Wales gained a try by full back Gareth Swales (Swansea) that Robinson converted and in the final minutes Nuthall, who last season was the youngest player to appear in a Welsh Cup final, crossed again for Robinson to convert.
There was still time left for Swales to collect his second try of the match to leave the try-count at 4-0 in favour of Wales.
Scorers.
Wales – Tries: M Nuthall (2), G Swales (2). Cons: N Robinson (3). Pens: N Robinson (3).
