"He was in exceptional form in October in Aviva Premiership Rugby, ensuring he forced his way into the England set-up,' said Panel Chairman Paul Morgan.
Freddie, who also won the award back in February, added:
"I feel a huge sense of pride at winning this award for the second time. Receiving plaudits for my own personal performances is great, but I must do the same for my team mates who enable me to showcase my game with their tireless hard work, week in, week out.
"Aviva have given me £500 to donate to the charity of my choice - and I have selected for it to go to one of Alex Brown's testimonial charities, Restart.
"With an increasing number of players suffering career-ending injuries, it's great to be able to make a contribution to such a worthy cause."
Louisa Cheetham, Senior Sponsorship Manager at Premiership Rugby's title sponsors Aviva added:
"Another prime example of the great young talent on show in the Aviva Premiership. It looks like the growing clamour for his inclusion in the England team has now spread outside of Gloucester. Freddie has a very bright future ahead of him."
