Brydges was Member of Parliament for Cricklade in 1571 and for Gloucestershire from 1572 to 1573. He succeeded his father as 3rd Baron Chandos of Sudeley on 11 March 1573 and held the office of Lord-Lieutenant of Gloucestershire in 1586. He entertained Queen Elizabeth at Sudeley Castle in 1592.^[1]

Chandos died on 21 February 1594 without male issue and was therefore succeeded by his brother William who became the fourth Baron Chandos of Sudeley. He is buried in the Chapel of St. Mary at Sudeley Castle in Winchcombe, England.^[1]

He married Lady Frances Clinton (Scrivelsby, Lincolnshire, 1553 - Woburn Abbey, Bedfordshire, 12 September 1623), daughter of Edward Clinton, 1st Earl of Lincoln and his second wife Ursula Stourton before 1573.^[1] According to Joan Barbara Greenbaum Goldsmith's unpublished PhD dissertation, All the Queen's Women: the changing place and perception of aristocratic women in Elizabethan England, 1558-1620, Frances and her husband separated during the 1590s. She died at Woburn Abbey, home of her daughter Catherine, Countess of Bedford.^[2]
