The right of use assets is disclosed in note 9.

In April 2021 the Group signed an agreement to lease new premises in Cardiff, Wales, to house its corporate offices and laboratories. The agreement to lease allowed the Group to carry out the Cat A works and fit out prior to completion of the lease and its occupation in August 2021. The lease agreed was for a 5 year period with no break clause. The lease was recognised as a right of use asset in 2021. The recognition in 2021 of the right of use asset and corresponding lease liability were a non cash investing and financing transaction.
