Although still seen as a US-focused celebration in some quarters, the numbers suggest Halloween is now more than established on this side of the Atlantic as well. In 2013, the estimated UK retail value for Halloween stood at £230m. However, in the space of just four years, this has grown by 35%, with retail sales hitting £310m in 2016, according to Mintel. It predicts sales to grow another 3.2% this year, hitting £320m, with retailers such as John Lewis already crediting a rise in sales to Halloween buzz.
