Lowther inherited through his mother an estate carrying an interest at Lancaster, for which he was returned unopposed in 1722. On 4 Mar. 1726 he presented a petition for a bill to grant him the freehold of this estate, which he held on a crown lease with 22 years still to run. The petition was granted but the House passed a resolution that they would accept no more petitions of this kind, though in fact they subsequently allowed other grants of crown lands.
Sir Thomas Lowther also went against us. Sir Robert sent me to him but he told me immediately that he was obliged to vote for Lee [George] because he was his particular friend.
And a few days later:
I did all I could to get Sir Thomas Lowther down at the Westminster election. I wrote to him a very civil letter but it would not do.

On 21 Jan. 1742 Hartington persuaded him to vote against an opposition motion to set up a secret committee to inquire into the conduct of the war,
As for Sir Thomas Lowther I cannot say much for him. He seems a great deal biased by Sir James, and he has declared that he thinks they are pushing matters too far ... I have spoke to Sir Thomas to attend when the army comes on, and I think he seems to think that it would be improper to diminish our forces at this time, so I hope we shall have him with us.

Absent from the divisions on the Hanoverians in 1742 and 1744, he died 23 Mar. 1745.
