On 26 March, Bedene, the world no 83, was granted UK citizenship. Bedene said he planned to appeal against a new rule which prevents players from representing more than one country in Davis Cup. Bedene played three dead rubbers for Slovenia in Davis Cup action in 2010, 2011 and 2012.

On 30 May, the International Tennis Federation announced that Bedene would not be allowed to represent Great Britain in the Davis Cup in response to the Lawn Tennis Association who had appealed a rule brought on 1 January, forbidding players from representing two nations in the competition. Bedene's case had been based on his passport application being submitted before the new regulation was implemented. On 17 November, Bedene and representatives from the Lawn Tennis Association flew to Prague to appeal for the right of Bedene to play Davis Cup for Great Britain. However, the Lawn Tennis Association did not submit a 70-page summary of its support for the player until just before the meeting. The International Tennis Federation said the hearing of the appeal would be adjourned until the next board meeting on 20–21 March 2016, so it could consider the document.

He made his top 50 debut on 19 October 2015.

The International Tennis Federation, which was meeting in Moldova on 20 March, considered Bedene's appeal to represent Great Britain in Davis Cup. The International Tennis Federation decided that Bedene was not eligible to represent Great Britain in Davis Cup or the Olympics. Bedene decided to consider seeking a ruling from the Court of Arbitration for Sport.
