Energy in United Kingdom & Ireland

38 energy providers across United Kingdom & Ireland, publishing 52 APIs.

38 providers 52 published APIs 143 indexed documents

Energy across United Kingdom & Ireland — 38 providers on the APIs.io network sit in both cohorts, and between them they publish 52 indexed APIs.

28 of the 38 publish at least one machine-readable API; 10 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: 11 emerging, 9 thin, 8 developing, 5 strong, 4 minimal, and 1 exemplar.

Leading by rating: EDF Energy, UK Power Networks, Xoserve, Electricity North West, Northern Powergrid, Octopus Energy, and 32 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.
