Platts changes rollover date of UK Renewable Energy Guarantees of Origin

Platts, part of S&P Global Commodity Insights, has changed the rollover date of its UK Renewable Energy Guarantees of Origin (REGO) price assessments, from April 1 of each year to July 2. Platts published its decision to make the change on Jan. 20 here (opens in a new tab).

This change means that current compliance period REGOs will expire on July 1 of the current year, and roll to the next compliance period on July 2. This reflects the trading of REGOs until they are counted by Ofgem for the Fuel Mix Disclosure -- the main use of these certificates.

Prior to the change effective Feb. 17, 2025, Platts current compliance period REGOs rolled on April 1 of each year. This means that the current compliance period REGO assessment will have an extended compliance period through July 1, 2025.

For example, the current compliance period of CP-23 has been assessed from April 1, 2024 and will be assessed until July 1, 2025. Platts will now assess the new current compliance period as CP-24 from July 2, 2025, to July 1, 2026, at which point it would continue to roll on July 2 of concurrent years.

Platts publishes REGO price assessments for three years:

  • current compliance period REGOs (currently CP-23)
  • compliance period+1 REGOs (currently CP-24)
  • compliance period+2 REGOs (currently CP-25)

Platts symbols for these assessments will not change, but the compliance period they refer to will be extended. While the compliance period is shifting, Platts takes into account REGOs produced from April 1 of the current year to March 31 of the following year, and will continue to do so. For example, CP-24 will be assessed as the current compliance period from July 2, 2025 to July 1, 2026, taking into account REGOs produced between April 1, 2025, and March 31, 2026.
