Priority?

Post your PCR test in a priority post box near you as shown on the Royal Mail website - the post box will have a priority sticker on it.  This was our nearest 'priority' post box which looked more like something out of a Hitchcock horror (despite being Monday, the next collection was marked as being on Friday).  The next 5 boxes we sought out also had no priority sticker, just as, finally, the box at the sorting office didn't.
