Sarah Hall was elected Labour and Co-operative MP for Warrington South on 4 July 2024 with 23,201 votes (46.7 per cent) and a majority of 11,340 (22.8 per cent), defeating Conservative Andy Carter. The defining biographical fact of her career is a political dynasty in the same seat: she is the daughter in law of Mike Hall, Labour MP for Warrington South from 1997 to 2010 and a former leader of Warrington Borough Council. She succeeded her father in law in the constituency he held for 13 years, and she also worked for Charlotte Nichols, the Labour MP for neighbouring Warrington North.
Elected to Warrington Borough Council for Bewsey and Whitecross in 2016, she became Cabinet Member for Children's Services in 2021, leading on education, special educational needs, children's social care and safeguarding, having earlier served as the borough's Adoption Champion and Vice Chair of the Building Stronger Communities committee. She stepped down from the council before the 2024 local elections. She volunteers with the community food organisation The Bread and Butter Thing, was a founder of a local school uniform swap shop, fought for the Bewsey and Dallam Hub and opposed a waste transfer site. She was selected as Labour's candidate in July 2022.
She sits on the Public Accounts Committee from October 2024 and has served on the Bus Services Bill committee. She voted in favour of the Terminally Ill Adults (End of Life) Bill in November 2024, and in May 2026 she called on Keir Starmer to resign. A Public Accounts Committee member calling for the PM's removal while scrutinising government spending is a significant intervention.
