After the departure of Robert William Elliston from Bath, Egerton played Lord Townly in Colley Cibber's The Provoked Husband, Mr. Oakley in The Jealous Wife, Rolla in Pizarro, and many important parts.
Egerton left Bath for London in 1809, appearing on 28 Oct at Covent Garden during the O. P. Riots as Lord Avondale in Thomas Morton's The School of Reform.
In tragedy King Henry VIII, Tullus Aufidius in Coriolanus, Syphax in Cato, and Clytus in Alexander the Great were esteemed his best parts.
From this time until close upon his death he remained a member of the Covent Garden company, his chief occupation being secondary characters in tragedy or serious drama and what is technically called 'heavy business.'
On 1 July 1833, in conjunction with William Abbot, his associate at Covent Garden, he opened the Victoria Theatre, previously known as the Coburg.
The Thespian Dictionary says he gave in Birmingham in 1800 an entertainment of his own extracted from George Alexander Stevens's Lecture on Heads, &c., and entitled 'Whimsicalities.'
