 In 1681 he succeeded his father as second Viscount Cholmondeley, but as this was an Irish peerage it did not entitle him to a seat in the English House of Lords.He supported the claim of William and Mary to the English throne, and after their accession in 1689 he was rewarded when he was made Baron Cholmondeley, of Namptwich in the County of Chester, in the Peerage of England (which gave him a seat in the House of Lords).The peerage was created with remainder to his younger brother George.
