British Army WWII

My grandad died over thirty years. He never really spoke about his time in the army but i know he was in the King’s Liverpool Regiment and drove a Churchill tank. Before he died he ordered his medals and gave them to me. As a stupid kid i lost them over the years but I remember he had the France and Germany star, the War Medal and the Defence Medal. Although i might be misremembering as I’m reading the Defence Medal was given to people on the home front. He served in France so is it likely he’d have the Defence Medal? I have no way to get his records, i don’t have his death certificate or any power of attorney to request them.
