The process for passing the various types of Bills is almost similar in both - The House of Lords and the House of Commons. A Bill has to pass through several stages in order to become a law. The following stages are followed before a Bill becomes a Law:
Formal introduction of the Bill or the First Reading
The General Debate or the Second Reading
A detailed scrutiny, debate and amendments, if any are to be made. In the House of Commons, the Public Bill Committee takes care of all these stages. This stage is also known as the Committee Stage
There is also an opportunity for further amendments. This stage is also known as the report Stage
The House of Lords take care of the final debates and amendments. This also known as the Third Reading.
After a Bill is passed by both the Houses of the Parliament, it is returned to the House from where it got initiated.
Both the House of Commons and the House of lords have to agree upon the final text. There may be many exchange of discussions before both the Houses agree to a Bill word by word. After both the Houses agree to the Bill, it is forwarded for the Royal Assent. The Royal Assent is granted by the monarch.After going through all the above referred stages, the Bill now becomes a Law.
