Sedge Warbler ?

Hello folks,     just wanted to check an ID with you as two of these beauties turned up on our water garden below the balcony which was a huge surprise  !!    Looking at the bold supercilium and markings I was leaning towards Sedge Warbler but will welcome your more expert ID please.     

Taken from 3 floors up but enough for ID methinks.
