Williams joined Burton at the age of 15 after 7 years in the Aston Villa Academy. He has impressed with the Brewers and was handed his first professional contract by Jimmy Floyd-Hasselbaink in September.
Manager Matt Clarke said: "Charlie will add another option to our attacking area. I saw Charlie impress for Burton in their last round of the Birmingham County Cup, once I heard he was a Redditch boy we were even more keen to get him involved with us."
Charlie will go straight into the squad for The Reds next game against Rushall Olympic this Saturday (3pm KO). Tickets are available HERE.
