The e-MERLIN array has both the sensitivity and resolution to detect central image(s) of distant Radio-loud Quasers in radio quiet gravitational lenses. The detection of such images provide additional constraints for lens modeling. In particular, limits are places on the central surface mass density and black hole mass. In the case that a split central image is detected the the mass of the central super massive black hole in the lens galaxy may be determined. Maps produced by both the e-MERLIN array and the JVLA will be presented and their implications discussed. The current status and future of the e-MERLIN lens legacy programme will be reviewed.
