    Frequently asked questions

    Is your renewable electricity backed by renewable certificates?

    Yes. For every MWh of renewable electricity supplied, SmartestEnergy allocates UK-recognised renewable energy certificates (REGOs). Our reporting approach provides transparency over certificate allocation and supports accurate renewable electricity reporting.

    How can I evidence my renewable electricity supply?

    Customers receive an Annual Energy Report containing renewable consumption data and supporting certificate information. The report is designed to provide clear, traceable evidence of renewable electricity sourcing and support sustainability reporting requirements.

    What’s included in an Annual Energy Report?

    The Annual Energy Report includes:

    • A summary of renewable electricity supplied during the reporting period
    • Details of Renewable Energy Guarantees of Origin (REGOs) allocated to customer consumption
    • A breakdown of renewable fuel sources

    The report is designed to support sustainability reporting, stakeholder communications and internal engagement.

    How do you address concerns about double counting REGOs?

    REGOs are unique certificates recorded in the Ofgem REGO registry. The Annual Energy Report is produced using a registry-linked allocation approach, so the REGOs associated with your reported consumption can be traced back to specific certificates (including certificate identifiers). This improves transparency and provides an audit-ready trail that helps customers evidence claims and reduce the risk of double counting in reporting.
