The is England calling

So not really long ago ..I don't remember but I thought no more than last year I did a rewatch and I seem to remember at least 2 streaming services had Psych. Now I tried the Mentalist but I just thought meh why bother when I could watch Psych?

Only I can't ..it's not free on any service at present..does anyone know where ( in uk) I can watch the series? Just in case I've missed something please?
