formed since 1994. In 2021 there was a further expansion of the URNU, with new units in East Midlands, Belfast, Solent and Virtual. Solent URNU was a merging of Southampton URNU and Sussex URNU, the unit more to a brand new location in Portsmouth where it could be inside HMNB Portsmouth. East Midlands URNU and Belfast URNU were both new units to cover holes in the coverage of URNU units where there are also large numbers of potential students. Virtual URNU was also setup after a year and half of online URNU to cater to those unable to get to a unit due to distance or any other issue.
