Receptacle spacing when one is mounted tv
There is no height requirement for outlets other than 210.52.4 . This limits the height to 5-1/2' to be counted in the spacing. as no point more than 6' away from a receptacle or 12' between them measured horizontally along the wall. 
If your contractor won't drop one down the wall from the TV outlet (at a extra charge for the additional outlet time &amp; materials) I would complain. But at 5' and within 12' measured horizonaly along the wall this outlet meets the minimum code standard.
