Nathan Robertson and Jenny Wallwork won the mixed doubles title at the Swedish International in Stockholm to boost their Olympic qualifying hopes.
The Commonwealth silver medallists overcame Denmark's Mads Pieler Kolding and Julie Houmann 21-17 21-17.
Robertson and Wallwork expect to move up from 22nd in the world rankings as they chase Anglo-Scottish rivals Chris Adcock and Imogen Bankier.
Adcock and Bankier, 14th in the world, could only reach the semi-finals.
Britain collected a second title with Mariana Agathangelou and Heather Olver copying Robertson and Wallwork's dominance when they outplayed Eva Lee and Paula Lynn Obanana in the women's doubles final.
Robertson, 34, and Wallwork, 25, were contesting their first international final since the Swiss Open last March after suffering a poor run of form towards the end of 2011.
But they dominated Denmark's fourth seeds as they opened up a 16-9 lead on the way to taking the first game.
Robertson and Wallwork were just as dominant in the second game and from 8-2 up they never looked back as they eased to victory.
Agathangelou and Olver were held by the Americans up to 7-7 in the opening game before the second seeds eased away to take the opener on their first game point.
It was a similar pattern in the second game with the England pair pushing on from 5-5 to secure the title on their first match point and add another title to this season's Bulgarian Open success.
