The Parliamentary Constituencies Act 1986 (c. 56) is an act of the Parliament of the United Kingdom. It is the current legislation defining the constitution and work of the four parliamentary Boundary Commissions in the UK.

The act consolidated earlier legislation, namely the House of Commons (Redistribution of Seats) Act 1949 (12, 13 & 14 Geo. 6. c. 66), the House of Commons (Redistribution of Seats) Act 1958 (6 & 7 Eliz. 2. c. 26) and the House of Commons (Redistribution of Seats) Act 1979.

Repealed enactments

Section 8(1) of the act repealed 8 enactments, listed in schedule 4 to the act.

Amendment

The act has been amended by the Boundary Commissions Act 1992, and by various other statutes, and remains in force. In February 2011, the Parliamentary Voting System and Constituencies Act 2011 received royal assent, which substantially amended the act. The changes affected the Sixth Periodic Review of Westminster constituencies which provides for a review to be laid before Parliament that contains 50 fewer constituencies and less variation in electorates. It also provides for more frequent boundary reviews and a small reduction in the length of the consultation period.
