Hill was selected in England's 34 man squad for their 2018 summer tour of South Africa and was an unused substitute in the third and final Test. On 31 October 2020 he made his England debut, pairing with Maro Itoje in the second row, in England's delayed final Six Nations match away to Italy, which England won to become the 2020 Six Nations champions. In December 2020 Hill came off the bench for England as they defeated France in extra-time to win the Autumn Nations Cup. He scored his first International try against Italy during the 2021 Six Nations Championship.
