It's a "Large User" postcode - that is, one assigned specifically to a 
particular addressee which receives large amounts of postal mail.

In this case, it's a former (now closed) Natwest Bank branch in 
Richmond-on-Thames. So the postcode is now defunct, and will eventually 
be marked as such on a forthcoming update of the ONSPD and Codepoint Open.

(You can see the building in all its defunctness on Google Streetview, 
complete with a hole in the wall where the, er, hole in the wall machine 
once was: https://goo.gl/maps/A1DTcbcjBNFcHmdt7).
