Supply interruptions - performance commitment data

This data is the incidents used to calculate our supply interruptions performance commitment (PC) figure as part of our Annual Performance Report (APR). More information on the APR and our PCs can be found here Latest performance (

Lines with an interruption category of 'supply interruptions' contain information from an online reporting tool used for all network interruptions. Lines with an interruption category of 'no water' contain non-network incidents involving one or a small number of properties. Fields provided include high level location (e.g. Chippenham), type of interruption, reason, number of properties interrupted and information related to the duration.

All data is in accordance with the consistent reporting guidelines for the mandatory common PC for all supply interruptions of 180mins and more.

How the data is collated: All supply interruptions info is collated through online corporate dedicated systems. This is collated for the PC, and an extract with simplified location information was taken for this publication exercise.

For the remaining years of AMP7, an additional year of data will be added after the annual reporting period.
