Television actor Tom Chambers won the show on Saturday night after beating former model and broadcaster Lisa Snowdon and singer Rachel Stevens.
But BBC bosses are apparently organising a shake-up of the voting system.
The show prompted thousands of viewer complaints last month when former BBC political correspondent John Sergeant withdrew, forcing the BBC to offer refunds to those who had voted for him in vain.
Strictly's judges had criticised Sergeant's hapless dancing, but the public had voted off more talented celebrities instead because of Sergeant's bumbling charm.
The BBC had to issue further refunds after thousands of viewers complained when the show's producers decided not to eliminate any contestant after a glitch in the voting system.
