Hastings was born into a junior branch of the dominant Leicestershire family in this period. His father was the fourth son of the 2nd earl of Huntingdon and sat for the county in 1597.
Hastings inherited Leicester Abbey, just north of Leicester, from his father in 1603. He probably resided there from at least 1605 until 1613, when he sold it to the 1st earl of Devonshire (Sir William Cavendish†), although during his wife’s lifetime he continued to live near Leicester. After her death in 1618 he moved to Long Clawson, five miles north of Melton Mowbray in north-east Leicestershire. At around this time he also acquired the reversion of Humberstone, a property consisting of a couple of manors two-and-a-half miles north-east of Leicester.
In late 1603 Hastings applied to the corporation of Leicester to become their recorder, but was rebuffed.
In 1620 Hastings was nominated by the earl of Huntingdon, together with Huntingdon’s brother, (Sir) George Hastings*, to represent Leicestershire in the third Jacobean Parliament, and was returned unopposed. Granted leave on 13 Mar. 1621 ‘to give evidence against divers felons at the assizes at Leicester’, he had returned by 21 Apr., when he undertook to produce warrants issued by the licensers of alehouses and was named to the committee of inquiry. His only other committee appointment, on 30 Apr., was for the bill to prevent the holding of secret inquisitions. On 11 May, in the debate concerning the petition of the borough of Northampton against the anti-puritan chancellor of the diocese of Peterborough, Dr. John Lambe, Hastings complained that Lambe had persecuted some of the parishioners of Higham Ferrers in Northamptonshire for attending sermons in neighbouring parishes.
In June 1623, Hastings, together with Richard Knightley* and others, attended a debate between two Anglican ministers and two Jesuit priests at the house of Sir Humphrey Lynde* in London.
Hastings succeeded in taking his seat by 25 Mar. 1626, when he was the first Member appointed to consider a bill for the better suppression of unlicensed alehouse-keepers. Later that same day his petition against the sheriff was read. On 26 Apr. the issue was referred to a committee, from which Edward Littleton II reported on 3 May. The committee found in Hastings’ favour, but because the sheriff was young they recommended that he should only be admonished and made to pay Hastings’ costs. The report was approved the following day, when the sheriff acknowledged his guilt on his knees before the House. Hastings played no further role in the proceedings of the Commons, and was among those absent with leave at the call of the House on 2 June.
In September 1627 Hastings was reported to be too infirm to conduct public business and there is no evidence that he sought re-election to Parliament the following year.
