Between 1715 and 1754 the House of Commons consisted of 558 Members, elected by 314 constituencies. The 245 English constituencies (40 counties, 203 boroughs, 2 universities) returned 489 Members; the 24 Welsh constituencies and 45 Scottish constituencies returned one Member each.

The twelve Welsh counties each returned one Member to Parliament, using the same franchise as for the English counties. The largest of them could muster around 2,000 voters. There were 12 Welsh borough constituencies, 5 of them single boroughs, and the others groups of boroughs united for electoral purposes, using various franchises.
In Scotland, the pre-1707 franchise had been adapted for the purposes of the Union Parliament. 27 of the 33 Scottish counties each sent one Member to the House of Commons, with six of the smaller counties grouped together in pairs and one of each pair alternated with the other in electing Members, Parliament by Parliament. The Scottish burghs, with the exception of Edinburgh, were, like the Welsh ones, combined in groups for the purpose of electing Members of Parliament, with fourteen grou
