Centrica Plans
Centrica publishes no commercial API pricing. The only access tiers that exist anywhere on a Centrica developer surface are the two default Azure API Management products on the Centrica FieldOps developer portal (DEVELOPMENT environment), read verbatim from that portal's own management API. Both are subscription-gated and neither carries a price — they are access tiers, not paid plans. Real FieldOps access is a commercial partner arrangement with Centrica's field-service business; the production portal and gateway (api-developer.fieldops.centrica.com, api.fieldops.centrica.com) both answer 403 anonymously. No consumer or business energy-data API is sold at any price.
