Who Is Dot? Meet Sara Cox’s Down-to-Earth Sister
Dorothy – or “Dot” as she’s affectionately known – is Sara Cox’s younger sister and one of her closest confidantes. Born and raised in Bolton, Greater Manchester, the Cox sisters grew up in a tight-knit family where laughter was the loudest currency.
- Age gap: Dot is three years younger than Sara (born 1974), making her around 48 in 2025.
- Personality: While Sara’s the bubbly broadcaster, Dot is described as the quieter, more grounded sibling – though she’s no stranger to a cheeky one-liner.
- Family role: Dot is a mum of two and works in education, often credited by Sara as the “sensible one” who keeps her grounded.
Sara frequently shares throwback photos on Instagram, including one from 2023 showing the sisters in matching 80s perms – proof that sibling style disasters are timeless.
Childhood Adventures: From Bolton to Best Mates
Growing up in the 70s and 80s, Sara and Dot were inseparable. Sara has spoken openly on her BBC Radio 2 show and in interviews with The Guardian (March 2025) about their working-class upbringing:
- They shared a bedroom until Sara left for modelling in London at 18.
- Dot once “borrowed” Sara’s favourite jumper – and stretched it beyond recognition.
- Family holidays to Blackpool were filled with donkey rides, candy floss, and sisterly squabbles.
“Dot was my first best friend,” Sara told Woman & Home in a 2024 feature. “We fought like cats, but we’d defend each other to the end.”
These early years shaped Sara’s humour – and her deep loyalty to family, which she still carries into her 50s.
Dot in the Spotlight: Cameos, Radio Shoutouts & Viral Moments
While Dot prefers life out of the limelight, she’s become a quiet internet sensation thanks to Sara’s storytelling:
- Radio 2 mentions: Listeners love when Sara reads texts from “our Dot” – usually about burnt toast or school runs.
- Viral TikTok (2024): A clip of Sara recreating Dot’s teenage diary entries got over 2.1 million views.
- Charity work: The sisters teamed up for a Cancer Research UK fundraiser in Bolton last spring, raising £12,000.
Fans on X (formerly Twitter) often tag #SaraAndDot with memes – one popular post from June 2025 shows side-by-side photos of the sisters at 10 and 45, captioned: “Proof that Cox genes age like fine wine.”

As Sara said on her podcast Coxy’s Confessions (Episode 12, 2025): “Dot’s my emergency contact, my reality check, and my partner in crime – even if her crimes are just stealing my biscuits.”
