Utilities in United Kingdom & Ireland

25 utilities providers across United Kingdom & Ireland, publishing 33 APIs.

25 providers 33 published APIs 82 indexed documents

Utilities across United Kingdom & Ireland — 25 providers on the APIs.io network sit in both cohorts, and between them they publish 33 indexed APIs.

20 of the 25 publish at least one machine-readable API; 5 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.

By Kin Score band: 7 developing, 7 thin, 6 emerging, 4 strong, and 1 exemplar.

Leading by rating: EDF Energy, UK Power Networks, Xoserve, Electricity North West, Northern Powergrid, Hildebrand, and 19 more.

Region membership is derived from three explicit signals — a provider tag, a provider-name pattern, or a stated headquarters in the provider’s own description. This is a map of stated headquarters, not of markets served.

This page is the intersection of two independently computed cohorts: United Kingdom & Ireland and Utilities. A provider appears here only when it is already a member of both. United Kingdom & Ireland membership is matched on tag, name pattern, stated HQ, so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
