The end point energies of nuclear $\beta$ decays have been measured with a segmented planar Ge LEPS detector using both singles and coincidence techniques. The $\beta - \gamma$ coincidence has been performed with a segmented planar Ge LEPS and a single 10$\%$ HPGe detector. The $\gamma$ ray and $\beta$ particle responses of the Segmented planer Ge LEPS detector were studied using monte carlo simulation code GEANT3. The experimentally obtained $\beta$ spectrum was in reasonably good agreement with the simulation results. The experimental end point energies are determined with substantial accuracy for some of the known $\beta$ decays in $^{ 106}$Rh, $^{ 210}$Bi and $^{ 90}$Y. The end point energies corresponding to three weak branches in $^{ 106}$Rh $\rightarrow$ $^{ 106}$Pd decay has been measured for the first time.
