They joined their uncle and father Thomas and E. P. Baddeley in Leadenhall Street at the family firm, founded by their great-grandfather in 1790.

The brothers remained partners in the firm until 1919, when they retired leaving their cousin, Cyril Baddeley, to carry on in the family name.

His daughter Violet Baddeley twice reached the final of the All England Open Badminton Championships in 1922 and 1927.
