Further development of International markets was a key focus during the year. Growth across all International revenue was 60% reaching £4.4m. Ex-plan investment was made in the USA and Italy which has set these markets up for significant growth in 2018 following the raising of additional funding in December 2017. The Australian business continued to perform to expectation.

Marketing investment resulted in record levels of brand awareness and usage.

The Board remains confident of continued strong growth in 2018 and beyond. The Company intends to issue its full year results on Wednesday 21 March 2018.
