Burrell was admitted to Brooks’s Club, 12 Mar. 1803. He secured his father’s support for the Grenville administration in 1806 and hoped that it would lead to employment in the diplomatic line. Later that year he was at Vienna as an observer and prepared to act as private secretary to Robert Adair without emolument.
In the House he acted with opposition, seldom speaking. He voted for Catholic relief, 24 Apr. 1812, and throughout in 1813. He supported sinecure reform, 4, 7 May 1812 and 29 Mar. 1813. He voted with the majority for a stronger administration, 21 May 1812. He opposed the leather tax, 1 July 1812. On 14 Dec. 1812 he voted against the bank-note bill and on 11 Feb. 1813 against the vice-chancellor bill. His attendance was not steady. In 1815, taking no part in the Corn Law debates, he voted against the continuation of the militia, 28 Feb.; against fresh taxation, 13 Mar.; against resumption of war, 7 Apr.; against the civil list, 14 Apr.; against the property tax, 5 May, and against the Regent’s extravagance, 31 May. He opposed the Duke of Cumberland’s marriage grant throughout, 28 June-3 July 1815. In the session of 1816 he attended regularly, voting with other young Whigs against the address, 1 Feb., against interference in French affairs, 20 Feb., for retrenchment and against the renewal of the property tax, 18 Mar. He defended the Lincolnshire petition against it, claiming that all but one of his tenants who signed it had become bankrupts. He also attacked the tax on agricultural horses and unsuccessfully attempted to secure its repeal, 13 May. He resisted the temptation to offer for Lincolnshire on the Whig interest in August 1816: he was ‘not inclined to spend money’ on it, particularly as his brother hoped to replace him for Boston: which would no doubt involve two contests. In 1817 he continued to vote for retrenchment and (unlike his father) opposed the suspension of habeas corpus in February. Brougham then listed him as subscriber of £300 to a Whig evening paper.
In anticipation of a contest for his seat he assured the Boston electors, 11 Feb. 1818, that ‘peace, economy and liberty’ were his objects and, on heading the poll, called himself ‘the firm friend of civil liberty, and the free exercise of conscience; of judicious reform, and strict economy’ (19 June). He seems in the House to have avoided the issue of parliamentary reform. He was one of those Whigs who preferred not to sign the requisition to Tierney to be their leader and avoided party meetings. Having become unwell during a visit to Paris, he did not attend the first session of the ensuing Parliament until June 1819, when he voted steadily against the foreign enlistment bill.
Burrell retired in 1820, faced with another contest. His father died in debt and he sold many of the family art treasures, but his residence in Paris was not a matter of necessity: he liked ‘no place so well’.
