Looking at the House of Lords Journals in the first decade of the 1800s, the members often sat all week, including Saturdays. From some of their Minutes, I gather they began in the morning. One entry included the note that the House rose earlier than usual at 1 PM, suggesting the sitting day could be quite long normally. The hours they met and sat has been one of the more difficult pieces of information to come by. Though the Regency and the War of 1812 would have called for more discussions, it seems that the general sessions were shorter- only from February to July for several years.

Hours: Until 1888 The Commons met at 3:45 on Monday, Tuesday, Thursday, Friday. No cut-off time 40 were needed for a quorum in the Commons and 3 in House of Lords. There is a suggestion in some writings that the House of Lords met four or more days a week between the hours of 10:00 and 4. Other authorities say like House of Commons, the late hours were remarked on, and they often stayed late in the evening.

Regina Scott has a fabulous blog post listing when Parliament was in session:

Who was allowed to vote? Parishes or Boroughs? Only male landowners could vote, and if I remember correctly, their property had to be worth a certain sum.

A. Those who could vote: Qualifications for voters varied. Most counties allowed all who had a freehold worth 40 shillings a year to vote. Those who could vote for the members from the county were called 40 shilling freeholders. They had to occupy property that was charged a land tax of 40s a year.

Other qualifications were required to vote in borough elections.

Scot and lot: all householders who paid poor rate was required. The term scot comes from the Old English word sceat, an ordinary coin in Anglo-Saxon times, equivalent to the later penny. In Anglo-Saxon times, a payment was levied locally to cover the cost of establishing drainage and embankments for low-lying land and for ensuring they remain secure. This payment was typically a sceat, so the levy itself gradually became to be called sceat. In burghs, sceat was levied to cover maintenance of the town walls and defences.

In Norman times, under the influence of the word escot, in Old French, the vowel changed, and the term became scot. In 19th century, low-lying farmland in Kent and Sussex was still being called scot-land. Scot, though, gradually became a general term for local levies; a person who was not liable for the levy, but received its benefits, got off scot-free. 

Lot means portion/share, hence lottery and allotment. The phrase scot and lot thus meant the local levies someone paid and the share they received of local provisions; more generally, it meant rights and obligations in respect of local government.

Parliament had evolved from the king’s baronial court. Before the mid 19th century, burghs varied in their choice of franchise. In some burghs, the franchise was set at scot and lot; that is, people were only permitted to vote if they were liable for the local levies.

B. Householder: all who were not receiving alms or poor relief – the usual definition of a householder was a person able to boil a pot on his/her own hearth.

C. Burgage was voting rights attached to certain property in the borough – in England and Scotland tenure of land in a town was held in return for service or annual rent.

D. Corporation: Where a corporation runs the borough only members could vote.

E. Freeman: All freeman had the right to vote – a freeman was one who was not a slave or a vassal.

F. Freeholder: All freeholders could vote. A freeholder had a freehold, which was land held in fee, fee-tail, or for life. 

Peers could not vote.

1802 United Kingdom general election

The electoral districts were boroughs which could be a whole village or align with a parish.

I do not recall ever seeing a breakdown of electoral districts  in London and Westminster.Voters in 

London.          Middlesex          4           10,000

Westminster.   Middlesex.         2           12,000

How, exactly, would one go about standing for Parliament? If one goes looking, he/she will find all sorts of information about rotten boroughs, how some seats were totally under the control of certain influential families, and who could and could not vote, but it is difficult to find much of the truth about the process itself. I have the impression that stumping and making speeches was a later development (although I would be happy to be wrong!), and I am assuming that entertaining influential people to dinner would be necessary, but how would one go about reaching the few people who could vote, I cannot say with any authority.

There is the rumor that Duchess of Devonshire went out campaigning for Whig candidates, offering a kiss for a vote? So there must have been some campaigning.

Most agree that stumping and speeches and paying the voters ( bribing them with ale and beer) was flourishing well in the Regency.

Process: One declared for a seat. One did not have to be resident in the district.

Usually one had a party behind him for the contested seats.

The rotten boroughs and seats held by peers (they owned the village) were seldom contested.

Sir Ralph Milbanke nearly put himself into the debtors’ prison because of campaign debts. Much money was spent on the contested elections.

There really were not that many seats that were contested.

One had to be 21 years of age (though William Pitt the Younger and one or two others were younger than 21) and a member of the Church of England.

I am pretty sure that the Lord Chancellor ‘s office was in charge of the writs to the House of Lords, but am not confident if his or the Home Secretary’s office organized elections and proclaimed the winner of them and issued writs of summons to the next session of parliament for the House of Commons.

While some seats were strongly contested and could cost a man a fortune to win, most were obtained by influence and patronage.

Eighty-seven peers controlled the seats of 218 members.

Ninety commoners controlled the seats of 137 members.

The Government had influence in sixteen seats. The treasury had 11, Admiralty had 4, and Ordnance had one.

These totaled 371, or more than half the 474 English MPs.

Five counties ( including their boroughs) returned 142 MPs, or around a fourth of the total membership of the House of Commons. The number of voters in the five counties came to 48,443 out of a population of 1,221,671.
