Standing for election to Parliament for the first time in May 2015, Pow became the MP for Taunton Deane with a majority of 15,491 votes (26.8% of the vote). In July 2016, Pow was made Parliamentary Private Secretary (PPS) to Gavin Barwell MP, Minister for Housing, Planning and Minister for London in the Department for Communities and Local Government (DCLG). Pow supported the Conservative Government's moves to cap welfare, improve education and opportunities for young people, control immigration, deal with the deficit and enable people to be given the right climate to get on. She described herself as "a traditional Conservative with a twist of the contemporary with [her] own added touch of green!" Pow was selected by a capacity audience at an Open Primary held in Taunton in July 2013. It was the first time a candidate had been selected for the constituency in this way, with the audience voting. She was also the first female Conservative Member of Parliament that Taunton Deane had ever had representing them. She declared that she would vote Remain in the 2016 referendum on the UK's membership of the EU.
