Hewlett, 20, who has recently battled back from two long-term injuries, played in the Brewers pre-season friendly against Christchurch Meadow.
The young striker progressed through Burton's academy and earned himself a professional contract in 2020.
He made his first team debut in a 3-3 draw against Peterborough in the EFL Trophy in September 2020.
In June, Hewlett signed a new one-year contact extension with the Brewers.
Belper, who were recently promoted to the Northern Premier League Premier Division following their Midland's play-off victory, will be hoping that their new acquisition can bolster their attacking threat ahead of the new season.
