Branston joined Bristol Rovers on loan in November until the beginning of 2013. "Guy is a very experienced centre half at this level," said Rovers manager Mark McGhee. "He is a straight forward uncompromising player, who competes well, and I think he will do a good job for us." He scored on his debut in a 3–3 draw with former club Bradford City and was critical of Bradford manager Parkinson. "I had a hard time at Bradford," said Branston. "He stitched me up last year and made me work really hard for something that was never going to materialise. The only way you can show them is by being on the pitch and playing well." Branston made three more appearances for Rovers before McGhee was replaced by John Ward as manager, and returned to Aldershot when the loan expired. In January, he had his contract with Aldershot cancelled by mutual consent after playing in five matches for the club. He rejoined Plymouth Argyle later that month on a contract until the end of the 2012–13 campaign. "I know what Guy's all about, with his enthusiasm for the game. And he knows the game," said Argyle manager John Sheridan after Branston made his debut in a 2–1 win against Morecambe. "He probably talks too much, but I like him as a lad. You could see the lift the players got from him. He gets on with everyone, he talks to the younger players and tell them off when he has to. But he'll give them a hug when he has to." Branston was an ever-present in the team for the rest of the season, making a further 18 appearances as the club avoided relegation from the Football League. He signed a one-year contract extension in May 2013. His 2013–14 season was disrupted by niggling ankle and calf injuries, which limited him to 13 appearances by March 2014. A scan on Branston's ankle revealed he would not be able to play again for the rest of the season and, with little prospect of being offered a new contract, he was released by mutual consent to continue his ankle rehabilitation at home. In February 2015, he joined Notts County as Chief Scout and was tasked with overseeing all areas of scouting and recruitment at Meadow Lane. In May 2016, he parted company with the club. In July 2016, he was appointed as the operations' manager at Nuneaton Town. Branston was appointed as Director of Recruitment and Development at Chesterfield on 1 April 2017.
