The homegrown talent's improved terms has come about as a result of his prolific form for the Under-18s and reserves this campaign, with 25 goals in 24 matches.
Academy director Tony Carr was delighted to see the deal concluded. He told whufc.com: "Even though Freddie was already under contract, it is an indication that if a boy pushes on, does well and catches the eye the club will recognise that with a new contract. That is an incentive for any young player to keep working, keep improving and if they show sufficient improvement they will be able to extend their stay at the football club.
"He has been with us since a very young age. It is a real endorsement of the academy system - another local boy nurtured from a very young age into the professional ranks. We have got high hopes for him for the future."
