Farnham was elected to the Irish House of Commons for Lisburn in 1743, a seat he held until 1759. Crossing to England he also became Member of Parliament for Taunton at a ruinously expensive by-election in 1754, his father putting up £3,000 which had to be more than matched from the government's "secret service" funds to secure his election. He afterwards described the campaign, in a letter to Lord George Sackville, as "a great deal of smoaking, some drinking, and kissing some hundreds of women; but it was to good purpose... I may venture to say that I have now near 150 majority".

He also became a Privy Councillor in Ireland on the 19 September 1760. He remained in the British House of Commons until 1768, being re-elected in 1761 and supporting the governments of Lord Bute and George Grenville, though there is no record of his ever having spoken in the House.
