On October 20, 2025, Big Brother UK confirmed that the 2025 winner will receive a cash prize of £100,000. The series features 16 housemates, with three late arrivals, public voting, and weekly evictions leading up to a live finale expected in November. Hosts AJ Odudu and Will Best interview departing housemates during the broadcast.

Secret Room twist on October 19, 2025

Sunday, October 19, 2025 delivered a Secret Room shock. After a fake eviction, Sam joined returning housemates Emily and Farida in Big Brother’s Secret Room. In the early hours, Big Brother told the trio: “Secret Housemates … there is a secret room behind the mirror in the House. The Eye Spy Hole.” Emily quipped, “Talk about carpe-dieming.”

Sam reflected on the twist (“I got evicted, right … But I’ve not gone.”). Farida weighed in on Sam’s in‑house alliance: “Unfortunately, she is giving mean girls vibes.” Sam asked, “So do you think me being friends with Nancy has put me off and in a bad position?” Farida nodded.

The Secret Housemates also took on a mischievous task dubbed “ChatBBT,” with Big Brother explaining that “ChatBBT uses AI to analyse every word said in the House.” Sam reacted: “Stunning. The tables have turned, babes.” Emily joked, “Surely they’re not believing that.”

Contestants and past winners referenced

  • Craig Phillips — first winner, prize £70,000.
  • Nadia Almada — prize £63,500 (season five).
  • Chloe Wilburn — won £116,100 during “Big Brother: Timebomb” (series 16).
  • Ali Bromley — 2024 winner, prize £90,000 with 51.9% of the public vote; runner‑up Marcello Spooks. Other finalists listed were Emma, Hanah, Segun and Nathan.

The 2025 field began with 16 housemates, including three late arrivals. The public decides the winner during the live finale, and prior tasks can alter the prize fund, as seen historically.

House dynamics now

Secret Room conversations focused on Sam’s friendship with Nancy and how alliances can shape outcomes. Farida warned, “If you align yourself with the wrong person … it’s just food for thought.” Sam called the experience “really hard,” while Emily said, “It’s so intense.”

What’s next for Big Brother 2025

The finale date had not been announced as of October 20, 2025, though it’s expected in November. With Emily, Farida and Sam influencing from the Secret Room and “ChatBBT” sowing paranoia, expect more live evictions, interviews by AJ Odudu and Will Best, and the £100,000 prize on the line.

The Secret Room re-centres strategy late in the season. Historic prize fluctuations (from £50,000 to £116,100) show how twists can change incentives. With public voting determining the winner, reputational shifts from the Emily–Sam–Farida return, and scrutiny of Sam’s bond with Nancy, margins could be decided by small perception swings.

Big Brother UK continues on ITV2 and ITVX.
