RETAIL ENERGY SUPPLIER LICENSING AND OBLIGATIONS

1. Meaning and Regulatory Structure

Retail energy supplier licensing is the principal mechanism through which Great Britain regulates companies that sell electricity or gas to final consumers. A supplier cannot normally carry on regulated electricity-supply activities without an electricity supply licence under section 6(1)(d) of the Electricity Act 1989. Gas suppliers operate under the corresponding licensing framework in the Gas Act 1986. Ofgem, acting through the Gas and Electricity Markets Authority (GEMA), grants licences and monitors compliance.

Licensing performs several functions simultaneously: it protects consumers, supports competition, maintains continuity of supply, permits regulatory supervision and ensures that suppliers possess adequate operational capability. Once licensed, a supplier must comply with the applicable Standard Licence Conditions (SLCs) and any special conditions attached to its licence.

2. Standards of Conduct

A central obligation is contained in the Standards of Conduct, particularly SLC 0 for domestic consumers. These rules require suppliers to treat customers fairly and to structure their behaviour, information and customer-service processes around appropriate consumer outcomes. Ofgem also requires suppliers to enable informed consumer choices and give particular consideration to customers in vulnerable circumstances.

These obligations are deliberately principles-based. Compliance therefore requires more than mechanically following detailed rules; suppliers must consider whether their overall conduct produces fair outcomes.

3. Billing, Pricing and Contractual Obligations

Retail suppliers are subject to detailed conditions covering billing accuracy, back-billing, tariffs, contract changes and customer communications. Ofgem identifies, among others:

SLC 21 – billing and payment requirements;

SLC 21BA – restrictions concerning back-billing;

SLC 23 – notification of price and contractual changes;

SLC 26 – Priority Services Register obligations;

SLC 27 – payments, debt collection and disconnection;

SLC 28 – prepayment-meter requirements; and

SLC 31A-H – billing information, tariffs and price-comparison requirements.

Suppliers must therefore maintain effective systems for customer accounts, meter information, billing, complaints and communications.

4. Operational and Financial Resilience

Modern licensing increasingly focuses on whether suppliers can operate sustainably. SLC 4A concerns operational capability, requiring suppliers to maintain systems, processes and governance capable of serving customers and mitigating risks of consumer harm. Ofgem may investigate whether inadequate business processes themselves constitute licence breaches.

If a supplier fails, Ofgem may use the Supplier of Last Resort mechanism. Standard Licence Condition 8 permits GEMA to direct another licensed supplier to take over affected customers. For example, British Gas Trading was directed to supply customers following the failure of Breeze Energy.

5. Case Law

R (British Gas Trading Ltd) v Gas and Electricity Markets Authority [2019] EWHC 3048 (Admin)

Facts: British Gas challenged Ofgem's methodology for establishing the statutory default tariff price cap. The company argued that the methodology inadequately reflected costs faced by efficient suppliers.

Legal Issue: Whether GEMA had lawfully exercised its regulatory powers when setting the price cap while considering the statutory need for efficient licensed suppliers to finance their authorised activities.

Judgment: The High Court examined Ofgem's methodology against the statutory framework and emphasised that the regulator had to take the prescribed statutory considerations properly into account.

Legal Principle/Ratio: Regulatory control of licensed suppliers may restrict commercial freedom, but GEMA must exercise its powers consistently with Parliament's statutory criteria and must consider the financial position of an efficiently operated supplier.

Significance: The case demonstrates that supplier licensing creates obligations on both sides: suppliers must comply with regulatory conditions, while Ofgem must administer those conditions lawfully, rationally and consistently with statutory objectives.

E.ON Supply Licence Enforcement Decision (2015)

Facts: Ofgem investigated E.ON concerning price increases and requirements under SLCs 23.6 and 24.3. Suppliers were required to give customers advance notice of specified price increases so customers could switch without inappropriate termination charges.

Legal Issue: Whether E.ON had complied with its contractual-notification obligations.

Judgment: GEMA imposed a financial penalty following findings of non-compliance.

Legal Principle/Ratio: Licence conditions concerning consumer information are legally enforceable regulatory obligations rather than merely voluntary standards.

Significance: Retail suppliers must integrate licence compliance into ordinary billing and contractual operations.

6. Enforcement

Ofgem may investigate licence breaches, issue enforcement orders, require consumer redress and impose financial penalties potentially reaching 10% of turnover.

7. Conclusion

Retail energy licensing creates a comprehensive framework of consumer protection, fair dealing, billing accuracy, operational capability, vulnerability protection and continuity of supply. The system allows competitive retail markets to operate while ensuring that suppliers remain accountable to enforceable public-law and regulatory standards.
