Extension (The Extended Mixes) turns the eleven songs from Tension into full club versions, made for the dancefloor rather than the radio. Padam Padam, Hold On To Now and Tension get room for longer intros and breaks, and 10 Out Of 10 keeps the Oliver Heldens collaboration. The set appeared in 2023, shortly after Tension itself, and is spread across four sides at 45 rpm on vinyl.

This edition is a 2-LP on clear vinyl with neon pink and green splatter, in a gatefold sleeve.
