In February 1619 he became a Master of Requests, and in 1622 he was appointed comptroller of the royal household, "paying well for the post." Suckling had become wealthy and accumulated manors, fee-farms, and advowsons in various parts of the country. In September 1621 he was mentioned as Sir Richard Weston's most serious competitor for the chancellorship of the exchequer and in March 1622 he was promoted to be secretary of state. Charles I, upon his accession three years later, created him a privy councillor. thumb|Alabaster monument (circa 1611) to Sir John Suckling (politician)

In 1626 he was elected MP for Norwich and for Sandwich; he chose to sit for Norwich.Suckling married Martha Cranfield, daughter of Thomas Cranfield of London, and sister of Lionel Cranfield, 1st Earl of Middlesex. She died on 28 October 1613, aged 35. By her, he was the father of the poet Sir John Suckling. A monument of Sir John Suckling, his first wife, Martha, and family, can be seen in St Andrew's Church, Norwich.

He then married Jane Hawkins, widow of Charles Hawkins and originally of the Suffolk family of Reve or Reeve. His widow took as her third husband Sir Edwin Rich, of Mulbarton, Norfolk and on the default of her stepson carried into that family the estate of Roos Hall near Beccles Suffolk which Suckling had acquired in 1600 as his residence. On Suckling's death, Roos Hall had been inherited by Sir Alexander Temple (Suckling's brother-in-law) in lieu of repayment of a debt, but was later repurchased by the family.
