   That might be how you and your ilk would bodge such   
   installations, the rest of us would budget for the higher cost!   
   Anyway, when you say "cheapest" what do you actually mean, any   
   component sold in the UK has to meet the minimum BS (or what   
   ever) standard, IME cheapest means basic.   
      
   : having fewer outlets due again to cost. Resulting in the use of   
   extension   
   : leads or bodged extra sockets.   
      
   Utter rubbish, especially at the time when ring circuits first   
   started being used in the UK, houses were being built with the   
   same number of outlets (ask anyone who has modernised a house   
   from the 1950s or '60s). As for bodged extra sockets, that is   
   exactly what occurs with ring circuits, because of the over   
   rating of the circuit protection, thus one can (and often does)   
   find sockets added to spurs, thus over loading the conductor but   
   not circuit protection. Or, and this is even more dangerous,   
   incomplete rings so that there are in effect two radial circuits   
   with any number of outlets protected at 30A rather than the more   
   usual 15A for a radial circuit using the same conductor size.

   So why did you claim otherwise, making out that radial circuits   
   are somehow dangerous, if not an out-and-out fire risk?
