I am trying to recall a British prime minister, whose father also occupied the same post....may be you can assist me?
There are two. William Pitt the Younger (Prime Minister 1783-1801 and 1804-06) was the son of William Pitt the Elder, 1st Earl of Chatham (PM 1766-68). William Grenville, 1st Lord Grenville (PM 1806-07) was the son of George Grenville (PM 1763-65).

But, the House of Lords is what it is.
The House of Lords is for the most part full of retired and failed politicians. The House of Lords Act 1999 removed the seats of all but 92 hereditary peers.

...which is why Winston Churchill refused the offer of a earldom, fearing he would lose real influence having to vacate The Commons.
Most retiring Prime Ministers were at one time offered Earldoms, the most recent being Harold Macmillan who was created Earl of Stockton. Churchill was actually offered, and as you say declined, a Dukedom which is the highest rank in the peerage.

I knew that about Churchill, but not of the watered down influence of the hereditary peers. Any data on what percentage are hereditary?
Currently, 87 peers out of 778 are hereditary.
