Belfast’s Charles III parcel box – any others like this in the UK?

Northern Ireland’s first King Charles III parcel postbox was installed on 29 April at 25 York Street in Belfast, outside the Ulster University campus. It carries the royal cypher CIII R and has a larger hatch for small parcels. It’s also described as the region’s first solar-powered parcel box.

Does anyone know if there are others like this elsewhere in the UK, or whether this was a one-off landmark install rather than the start of a wider rollout? It’s currently the only one we have on the map.
