Is a fuel system flush worth it?

My Dacia Sandero Ambience has just had its third service by the main dealer. They are recommending a fuel system flush to remove moisture. My car has only done 12000 miles, I run it on BP Ultimate petrol and it's kept in a heated garage. How necessary is it to have this procedure done?

This is being routinely offered as a revenue earner, but because you use BP Ultimate that already contains detergents and because you keep the car in a warm garage I don't think you need the fuel treatment.
