Second half goals from Nikita Parris and Karen Carney secured top spot for the Lionesses, who needed a win or a draw to become winners of the group .
England were unable to break through the Belgium defence in the first half but looked far more dominant after the interval and firmly ensured that they would conclude a sixth straight qualifying campaign unbeaten.
Manchester City striker Parris was the first to open the scoring as she headed home a Carney cross in the 65th minute. The provider turned goalscorer five minutes from time, beating a player in the box before unleashing a shot which took a wicked deflection off a Belgium defender to double the away side's advantage.
This result concludes Group 7 for Mark Sampson's side, who have recorded seven wins and a draw, whilst netting 32 times and conceding just one goal throughout the campaign.
England had already qualified for next summer's tournament in the Netherlands thanks to the 5-0 thumping of Estonia on September 15th, but were determined to seal qualification in style to set a precedent going into the finals.
Belgium, the only team to take points off England during the campaign could have qualified as Group 7 winners with a win over the Lionesses - but after succumbing to defeat on Tuesday night, the Red Devils were forced to settle for second place.
Estonia finish bottom
Estonia, the weakest link of the teams, were convincingly beaten 5-0 by England in the final fixture of their qualifying campaign. The Blues have never got going in the group stage - not only have they finished bottom of Group 7 with zero points on the board - but they have also failed to score a goal in any of their eight games played.
Serbia, however, have had a mixed bag of results in qualifying - they have secured victories both home and away against Estonia, whilst victorious in their final game against Bosnia & Herzegovina with a 4-2 win.
On the other end of the spectrum the Lionesses have given Serbia a really thrashing in both the home and away fixtures, Serbia have conceded seven goals to Mark Sampson's team which gave their qualification chances a real battering.
Bosnia & Herzegovina finished their campaign with a defeat to Serbia meaning they close out the group stage in fourth place with nine points on the board.
