I couldn't say for sure but the box looks like a control box for mains equipment.Could be street lighting or even a drainage pump in the vicinity of the box. The land it is on looks like street owned property reserved for the box. There is a lamp standard in front of the box on the pavement.If thats the case you won't be able to get it moved.I say this because it is outside of your boundary wall. Of course I can be totally wrong.
