How to find parliamentary bills in our library
This guide explains how to find parliamentary bills in our library.
Parliamentary bills are presented to parliament for debate. They either contain a proposal for a new law, or a proposal to change a law that already exists.
Parliamentary bills are published in two series:
- House of Commons (Commons bills)
- House of Lords (Lords bills)
Passage of bills through parliament
A bill can start in either house and usually passes through the same stages.
If ‘HL’ appears after the title of a bill as it passes through parliament (for example ‘Act of Union Bill [HL]’) it means that the bill started its passage in the House of Lords.
A bill usually (but not always) fails if it doesn’t pass all stages before the end of the parliamentary session.
- First reading. This is simply the introduction of the bill to the house.
- Second reading. This takes place after the bill is published for the first time. The general principles are debated, but no amendments made.
- Committee Stage. The bill is debated clause by clause and amendments made. This usually takes place in a Public Bill Committee made up of a cross section of MPS with knowledge of the topic, or by the whole house.
- Report Stage. The bill is reprinted to incorporate all amendments made at Committee Stage. MPs not involved so far now have an opportunity to make amendments.
- Third reading. The bill is debated again in general terms, but no further amendments can be made.
- The bill is passed to the other house and the above stages repeated.
- Royal Assent. When the bill has completed all stages and both houses have agreed on the text, the bill is submitted to the Crown. This is a formal procedure where permission is given for the bill to become an act and it becomes law.
Bills are identified by a number, which you can find on the front page. Each time a bill is reprinted it is given a new number.
For Commons bills the number format is ‘Bill 34’.
For Lords bills the number format is ‘HL Bill 34’.
When government bills are first printed, they’re usually accompanied by a separately printed explanatory memorandum. This explains what the bill is for. There are some exceptions to this, such as appropriation and consolidation bills.
Finding bills in our library
We hold bills in hardcopy (microfiche) and on the subscription database, Public Information Online. In our microfiche collection, we hold:
- Commons bills from 1801 to 2016
- Lords bills from 1984/85 to 2016
Lords bills for the 1984/85 and 1985/86 parliamentary sessions are included in the House of Lords Papers sequence. From 1986/87 Lords bills are a separate sequence.
To find bills on microfiche you will need to find the bill number. For bills before 1979/80 you will need the volume and page numbers of the microfiche.
Our microfiche collection is held in stores, please ask staff.
The Public Information Online (PIO) subscription database contains:
- Lords bills from 1901 to current session
- Commons bills from 1919 to current session
Ask our library staff for help finding bill numbers and access to the PIO database.
Finding the number of a bill
There are several ways to find the number of a bill in our library.
Index to House of Commons parliamentary papers
We have the index to House of Commons parliamentary papers for bills from 1801 onwards. It can identify:
- bill numbers
- the volume and page numbers of the microfiche (if needed)
The microfiche parliamentary papers also have an index at the end of each session.
Printed indexes to bills, estimates and reports
We keep printed indexes to bills, estimates and reports from 1910 to 1969 behind the library enquiry desk.
These indexes give the microfiche volume and page numbers.
HM Stationery Office/The Stationery Office catalogues
These contain lists of House of Commons and House of Lords bills from 1910 onwards with their bill numbers.
They are kept in our library in bay F1.
The House of Commons Sessional Information Digest
These digests contain lists of bills from the 1983/84 to 2010/12 parliamentary sessions. It includes the bill numbers and details of the stages the bills reached in both Houses.
This is kept in our library in bay E7.
You can find most bills from the 2001/2002 parliamentary session onwards on the UK Parliament website.
