Reg has a Cockney accent, attitude, and tone. He has a tendency to be sarcastic and loves to crack a joke. He is very confident about who he is and what he does even though he sometimes makes remarks that sound self-deprecating.
Reg also likes to sing himself some tunes to keep himself occupied, though this often annoys the workmen at the scrapyard.
- In Shorts 5, audio from Tale of the Brave is used, and played over again, of Reg saying "Allo mate!" The Audio is provided by Tim Whitnall.
