You’ll have to explain how your research contributes to knowledge, the novelty of your work, your contributions, and impact of the research or potential impact and benefit to the digital technology sector in the UK.
Your referees don’t necessarily need to repeat the same phrase but can use other qualifying phrases to describe how exceptional your research is.

Ok great thank you so much
