South Cambridgeshire.

Pippa Heylings has made environmental protection her most visible cause since entering Parliament. In February 2026 she introduced a ten-minute bill to protect UK chalk streams -- rare waterways running through her South Cambridgeshire constituency -- and backed a push for UNESCO status for them. She has also publicly condemned Anglian Water for "repeated failings" and called for a price cap on heating oil, translating local concerns into formal parliamentary action. Her one rebel vote came on the Terminally Ill Adults Bill in June 2025, when she backed a new clause requiring the Secretary of State to issue guidance on end-of-life provisions, breaking with the Liberal Democrat majority on that specific question.

Her voting participation sits at 58%, below the Commons average, though she has cast 303 votes and contributes heavily in debate -- 233 contributions across 119 debates, with energy, environment, and cost-of-living dominating her speeches. She votes with her party 99.7% of the time, making her a near-perfect party-line voter outside that single conscience vote. The stance data shows she is strongly aligned with Lords scrutiny (96%) and parliamentary scrutiny (95%), consistent with her repeated votes in April 2026 defending Lords amendments to the English Devolution and Community Empowerment Bill against government attempts to overturn them. She sits slightly more pro-landlord and more strongly anti-benefit-cuts than her Lib Dem colleagues.

Heylings holds no select committee seat, which limits one avenue for detailed parliamentary influence. Her news coverage is largely positive on environmental and constituency issues, with 50 articles in the past 90 days skewing toward local government and health. The volume of local coverage suggests strong constituency engagement, though the near-zero average sentiment score on local government articles points to coverage driven by ongoing issues rather than clear wins.
