Platts launches UK HEFA SAF Certificate assessments April 27

Platts, part of S&P Global Energy, has launched daily assessments for UK HEFA Sustainable Aviation Fuel (SAF) Certificates effective April 27, 2026.

The assessments reflect the value of UK SAF Certificates generated from the delivery of SAF produced via the hydrotreated esters and fatty acids (HEFA) pathway and used to demonstrate compliance with the energetic obligation placed on aviation fuel suppliers under the UK SAF Mandate.

The launch follows an increase in liquidity on entering the 2026 compliance period, driven by heightened obligations.

Under the policy, the obligation period ends on Dec. 31, and obligations are surrendered on Sept. 15 the following year.

These prices are assessed for the most recent obligation period that has yet to be surrendered, alongside the following obligation period.

Platts UK HEFA SAF Certificate assessments include

• A previous year vintage from the start of January until Sept. 15 (starting from the beginning of 2027)

• A current year vintage from the first to the last working day of the calendar year

• A next year vintage from the start of November to the last working day of the calendar year.

For example, Platts will publish 2027 UK HEFA SAF Certificates as next year obligation from Nov. 2, 2026, until Dec. 31, 2026. From Jan. 4, 2027, until Dec. 31, 2027, they will be published as current year obligation. Finally, from Jan. 3, 2028, until Sept. 15, 2028, they will be published as previous year obligation.

The assessments reflect transactional volumes from 500,000 to 5 million UK SAF Certificates. Volumes outside of these parameters may be considered and normalized to the basis range. Each certificate discharges 34MJ of the obligation.

The assessments reflect the first-quarter of the year transfer and payment terms of 5-7 days after the transfer. Pricing information reflecting other terms may be considered and normalized to the specification. The assessments are published daily and reflect a 4:30 pm London time market close in pence per certificate, following the London publishing calendar.

The assessments are published under the following symbols:
