In the UK the pilot does not need to have the runway (or field) in sight.
MATS Part 1 says
12 Visual Approach
12.1 To expedite traffic at any time, IFR flights may be authorised to execute visual approaches if the pilot reports that he can maintain visual reference to the surface and
a) the reported cloud ceiling is not below the initial approach level; or
b) the pilot reports at any time after commencing the approach procedure that the visibility will permit a visual approach and landing, and a reasonable assurance exists that this can be accomplished.
