Ofgem’s Licence Framework: A Primer for Small Generators and New Market Entrants

Ofgem regulates electricity licences that govern generation, supply, distribution and transmission in Great Britain. Full generation and supply licences confer broad market rights, but the regime also recognises exemptions and commercial arrangements that allow small generators to participate without holding a full licence. Many small-scale projects rely on licensed suppliers, aggregators or power purchase agreement counterparties to access wholesale and balancing markets. A key practical implication is that a project’s commercial route — whether merchant sales to a supplier, a sleeved arrangement through an intermediary, or contracting with a corporate buyer — determines revenue profile and counterparty credit risk. Ofgem’s licence conditions and market rules also shape obligations around metering, settlement and reporting. While the licensing framework is technical, it creates the structure within which contract types operate and counterparties assume obligations. For smaller projects, aggregation services can enable participation in ancillary markets and provide more sophisticated settlement and trading access than a standalone small generator could achieve. However, aggregation introduces an intermediary that becomes a credit and operational dependency; understanding the aggregator’s terms, contractual protections and regulatory standing is therefore important. For retail investors considering fractional exposure to small renewable projects, the Ofgem licensing context matters because it defines the market route and counterparty layers behind revenue streams. Fractional structures that clearly disclose the commercial pathway, the regulatory role of licensed counterparties and the nature of contract risk allow investors to evaluate how generation translates into cash flows.
