The Boost bar was introduced in 1985 and contained coconut and caramel. In 1989 it was joined by two new variants, peanut and biscuit. Both coconut and peanut variants were discontinued in 1994.
This overhaul saw a completely new wordmark, and the main colour of the wrapper switched to blue, which has been used ever since. The Cadbury's logo was also placed in a box.
A slight edit in 1996 saw the blue/red/white colour scheme kept but made some slight changes including a new wordmark and the removal of the box in which the Cadbury's logo sat.
This logo was originally introduced on the Boost Guarana variant in 2002 and was made the bar's main logo following the switch from Cadbury's to Cadbury.
This logo marked the end of the blue/red/white colour scheme after 15 years and introduced a new blue/black/gold variant.
In 2018, a slight redesign was introduced, with an altered font, and the Cadbury logo now surrounded in purple.
