By 1691, he had been appointed a Gentleman Usher of the Privy Chamber to Queen Mary, an office he held until 1694. He may have been the "Bertie" who contested Liskeard that year, but stood fourth in the poll. In 1699, he was successfully sued in the Court of King"s Bench by Sir Philips Coote for having an affair with Coote"s wife, Lady Elizabeth, the daughter of William Brabazon, 3rd Earl of Meath.
He unsuccessfully contested Mitchell in December 1701, on the strength of his auditorship.
Bertie"s salary as a Gentleman Usher had been converted to a pension upon the death of Queen Mary, but he found it increasingly difficult to collect under the Whig administration, and was forced to appeal to Lord Oxford, the Treasurer, for assistance. Bertie married Lady Elizabeth, for some time the object of his affections, in 1711, but had no issue by her.
Bertie opposed the attainder of Sir John Fenwick in 1697. However, he escaped dismissal from his auditorship when other members of the family were put out of office that year.
