In 1741, Wallop was returned to Parliament on his family's interest for Andover;^[1] he and John Pollen defeated William Guidott and John Pugh, the former a local official and former MP who had gotten himself disliked by the Andover corporation.^[6] Wallop was likewise returned for Whitchurch, where he had inherited an interest through his wife, but chose to sit for Andover.^[7]

He sat as a Whig, supporting Robert Walpole's administration, and voted for Giles Earle in his unsuccessful candidacy for chairman of the Committee of Privileges and Elections that year. He abstained from the vote to investigate Walpole's conduct in 1742. In 1743, his father (who had lost a number of local offices in Hampshire on Walpole's fall), was created Earl of Portsmouth, and Wallop adopted the style of Viscount Lymington. He voted against the Carteret Ministry in 1744 on their bill to hire Hanoverian troops for the War of the Austrian Succession.^[1] Lymington was considered a supporter of the Pelham government in 1747, when he and Pollen were returned for Andover without a contest.^[6] Lymington died in late 1749, in the life of his father.
