tbh with some of these centralised mail handling sites i'm not even sure recorded delivery can be done .
In the past, I seem to recall that all personal tax stuff
was addressed to Ty Glas (Wales) , and all businesses
were assigned to either the Bingley or Cumbernauld catchments.
So your mail at the minimum would be delivered
directly to the site where someone would eventually
physically handle it in some manner.
