Ofgem, the Office of Gas and Electricity Markets, is the non-ministerial government department that regulates the gas and electricity markets of Great Britain (England, Scotland and Wales), drawing its powers from the Gas Act 1986, the Electricity Act 1989 and the Energy Act 2023. It licenses the companies that make, transport and sell energy, sets the price cap, runs the RIIO network price controls, administers environmental and social schemes such as the Renewables Obligation, REGO and Feed-in Tariffs on behalf of government, grants and supervises the Smart Meter Communication Licence held by the Smart DCC, and imposes the Data Best Practice licence obligation that requires network licensees to treat Energy System Data as presumed open. It sits above the value chain rather than in it - it holds no customers, no meters and no wires. Its own API posture is the plain finding: Ofgem publishes NO API of any kind. There is no developer portal, no api., docs., data. or developer. subdomain, no OpenAPI, no CKAN endpoint. Market data is genuinely open but delivered as chart images, CSV and XLSX file downloads from the Ofgem Data Portal; consumer data does not exist here at all, because Great Britain mandated the smart-meter INFRASTRUCTURE rather than a consumer data right, and no CDR-equivalent obligation binds either Ofgem or the suppliers it licenses. Ofgem's two operational registers - the Electronic Public Register and the Renewable Electricity Register - are login-gated applications whose backends are undocumented and unpublished. Ofgem is therefore a regulator that demands open, discoverable, interoperable data from the industry it supervises while shipping none of it programmatically itself.
