UK coffee giant Costa is ditching its surcharge for plant-based milk for Christmas.
In addition, the chain revealed it may be adding oat milk to its menu next year.
The brand made its announcement on Twitter, saying: "Want another reason to be merry?
"We're making our dairy alternative coconut, almond and soya completely free this Christmas. Enjoy."
It confirmed that soy milk, which currently carries no surcharge, will still be included in the price of the drink after Christmas. It has not yet confirmed whether the other milks will still be free.
The move follows a campaign launched earlier this year by vegan charity Veganuary.
The campaign launch was coordinated with World Plant Milk Day on August 22, with Veganuary calling the surcharge 'a tax on climate-conscious customers'.
It called out chains including Starbucks, Pret and Costa for charging between 20p and 50p extra for non-dairy milk.
*This article was corrected on November 6. It previously reported that Costa Coffee said the plant-based milks would continue to be free after Christmas. This was an error, as Costa Coffee just confirmed soy milk would continue to be free after Christmas.
