Charles was the second son of Philip Medows, deputy ranger of Richmond Park, and Frances, only daughter of William Pierrepont, Earl of Kingston-upon-Hull. He entered the navy, attaining the rank of post captain, before resigning in 1763.
His uncle the 2nd Duke of Kingston (d 1773) named Charles as his heir in his will. Charles's elder brother Evelyn challenged the will, and initiated the proceedings which eventually found the Duchess of Kingston to be bigamous, but failed to overturn its provisions. Charles succeeded to the duke's estates (though not his title) on the death of the Duchess of Kingston in 1788, and assumed the surname Pierrepont in place of Medows.
Sponsored by the Duke of Newcastle, he became M.P. for Nottinghamshire in 1778. He was not a prominent parliamentarian, but had Whig sympathies and was a supporter of the Duke of Portland, whose influence helped him to be raised to the peerage as Baron Pierrepont of Holme Pierrepont and Viscount Newark in 1796. In April 1806 he became Earl Manvers.
He was interested in agricultural reform and was a prime mover behind a large number of enclosure schemes in Nottinghamshire from the 1780s to the 1810s. He became vice-president of the Board of Agriculture in 1803.
He died in London in June 1816 and was buried at Holme Pierrepont.

- Evelyn Henry Frederick (1775-1801)
