RIIO (Revenues = Incentives + Innovation + Outputs) is our framework to ensure that the monopoly companies operating our gas and electricity networks have sufficient revenue to run and invest in networks that efficiently deliver what customers value.
The current electricity and gas transmission and gas distribution price controls (known as RIIO-2) end on 31 March 2026. The next price control (RIIO-3) will run for five years, from 1 April 2026 to 31 March 2031.
Following our review of the RIIO-3 business plans submitted by the network companies in December 2024, we are now consulting on our Draft Determinations for RIIO-3.
Please send all responses by 26 August 2025 to RIIO3@ofgem.gov.uk.
