We study left-right symmetric supersymmetry and the constraints on its Higgs sector from LHC data. The model has a light doubly charged Higgs, whose mass comes from radiative corrections. The LHC bounds on the doubly charged Higgs mass reduce the parameter space significantly. We look at Higgs branching ratios and low energy constraints. We find that the Higgs decay width to bottom quarks can differ largely from the SM prediction at large tan beta and hence moderate values of tan beta are favoured.
