The O2, London

Tom Grennan has officially announced the GRENNAN '25 Tour – his biggest arena tour to date – with a landmark London show at The O2 on Saturday 6 September 2025.

The tour coincides with the announcement of his highly anticipated fourth studio album, Everywhere I Went Led Me To Where I Didn't Want To Be, set for release on 15 August 2025 via Insanity Records. The 15-track album, featuring the brand-new single ‘Shadowboxing’, follows the chart-topping success of 2023’s What Ifs & Maybes.

This new chapter comes on the heels of Tom’s festive Top 3 hit ‘It Can’t Be Christmas (Amazon Music Original)’, which went silver during its first holiday run - his highest solo chart placement to date, just behind Christmas legends Wham! and Mariah Carey.

With two number one albums, multiple BRIT and Ivor Novello nominations, an MTV Award for Best UK Act, and a string of airplay hits and sold-out arena shows, Tom Grennan has cemented his place as one of the UK’s biggest artists. Last summer, he headlined his biggest show yet - a sold-out 25,000-capacity crowd at Gunnersbury Park—and now he’s taking it even further with the GRENNAN '25 Tour.
