This article introduces a comprehensive, machine-readable dataset cataloging the procedural evolution of the UK House of Commons from 1811 to 2015. It demonstrates how this unique resource enables scholars to measure legislative change quantitatively and explores its potential through an empirical test. The findings suggest that parliamentary procedures have remained relatively stable despite major societal shifts, offering new insights into institutional continuity. This dataset provides a valuable tool for comparative analysis of procedural reforms across democratic systems.
