We report the impact of hydrostatic pressure (0-1.97 GPa) on superconductivity of recently discovered 2K superconductor Sr0.5La0.5FBiS2. Resistivity under pressure measurements are performed by using HPC-33 Piston type pressure cell with Quantum design DC resistivity Option. The superconducting transition temperature (T-c) is increased by 5 fold to around 10 K with just above 1 GPa pressure, which remains nearly unaltered for studied higher pressures of up to 1.97 GPa. The fivefold increase in T-c accompanied with decrease in normal state resistivity of Sr0.5La0.5FBiS2 with just above 1 GPa pressure calls for the attention of solid state physics community.
