Interactive quiz and podcast Guestimators has returned for Season Four with a new membership product and live event at the Cheerful Earful Comedy Festival.

Produced by Lock It In Studio and presented by Andy Bush – the voice of Hometime for more than two million weekly listeners on Absolute Radio – Guestimators sees the British public answer a range of irreverent questions with no definitive answer.

Each Monday quizzers are challenged to identify the most common answers given to these questions; the Thursday podcast then sees Bush challenge a celebrity guest to the same quiz, before the answers and weekly leaderboard are revealed.

The first celebrity podcast of Season Four is out today and features Cherry Healey, best known for presenting BBC show Inside the Factory for more than a decade.

The new season also marks the launch of a membership through Supporting Cast – offering quizzers and listeners extra questions and ad-free episodes – and a first live event.

Guestimators Live will feature an interactive quiz, real-time leaderboard and celebrity guests, and will be held in South London at The Bedford in Balham on October 17 as part of the Cheerful Earful Comedy Festival.

Guestimators’ production company Lock It In was founded in 2024 by Bush, Will Nichols (former VP, Content Development at Universal Music) and Matt Cutler, the sports journalist behind documentary The Pirates vs The Premier League and women’s football podcast Expected Goals.

Other productions in Lock It In’s portfolio include Scarred For Life, the TV and film podcast where celebrities confess three terrifying items or events from their childhood; Away Days, the football podcast led by indie rock drummers Chris “Woody” Wood (Bastille) and Piers Hewitt (The Boxer Rebellion), and DEADPOD, a comedy podcast that looks to break taboos around death.
