Hi all, need help again

Just discovered that my dad may have been buried in Hull, I was always told that he was cremated and his ashes scattered, does anyone know how I can find out?
If anyone has access to the records, he died 08/08/1973 but there was an inquest that didn't end untill Nov 1973 so unsure when he would have been buried. His name was George Leonard Smith d.o.b 27/04/1946, he died in Hull infirmary.
Thank you
