Hooker signed for Division Two side Brentford in a £5,000 deal on 14 November 1994, only a week after joining Gillingham. Hooker initially made Capital League appearances for the club's reserve team and was called into the senior side for the first time for a league match versus Peterborough United on 10 December. He made his Football League debut when he replaced Darren Annon during the 2–2 draw. It was his only involvement in the first team during the 1994–95 season. He made regular appearances for the reserves, scoring five goals and helping the team to second place in the Capital League.
Hooker found himself out of favour during the early part of the 1995–96 season, but an injury to Ijah Anderson saw Hooker called into the team to make his first start for the club in a 0–0 draw with Bristol City on 12 September 1995. He started four games in a row and won "star player" recognition for his performance in a 1–0 home win over Walsall on 16 September. Carl Asaba replaced Hooker in the starting line-up and Hooker failed to appear again until his was used as a Winger in a 2–0 defeat at home to Shrewsbury Town on 4 November. Hooker appeared as a substitute for Nicky Forster in the following game and made his final appearance for the club as a substitute for David McGhee in a 4–0 FA Cup first round replay win over Farnborough Town on 11 November. Hooker was released at the end of the season, having made just eight first team appearances for the Bees.
Hooker dropped back into Non-League football and played for Isthmian League Premier Division side Bishop's Stortford during the 1996–97 season. Hooker signed for Isthmian League Premier Division new boys Billericay Town in 1997. He made 48 appearances and scored six goals during the 1997–98 season. He left the club at the end of the 1998–99 season to join fellow Isthmian League Premier Division side Braintree Town. Hooker joined Isthmian League Division One side Harlow Town in the summer of 2000, playing two seasons before retiring from football in 2002.
