Feed-in Tariffs (FIT) - Payments and tariffs
Summary
Ofgem's FIT tariff and payments reference page sets out how generation and export tariffs are calculated for accredited installations under the closed scheme. Tariff rates are set by DESNZ and indexed to CPI from FIT Year 17 onwards, replacing the previous RPI indexation. The scheme closed to new applications on 1 April 2019 but continues to pay existing generators for their 20-25 year tariff periods.
Why it matters
FIT levelisation costs are socialised across all licensed suppliers and passed through to consumer bills. The switch from RPI to CPI indexation slightly reduces the escalation of these legacy costs, but the fundamental structure — administered prices guaranteed for decades — remains a fixed charge on the system that no market signal can adjust.
Key facts

Feed-in Tariffs (FIT) - Payments and tariffs | Ofgem Please enable JavaScript in your web browser to get the best experience. BETA This site is currently in BETA. Help us improve by giving us your feedback . Close alert: Feed-in Tariffs (FIT) The FIT scheme closed to new applications from 1 April 2019. Read more about the FIT scheme closure You can find the tariff rates available under the relevant scheme in the ‘publications and updates’ section below. Tariff rates for all installations are set by the Department for Energy Security and Net Zero and are published in accordance with the Standard Conditions of Electricity Supply License . How are my payments calculated? A tariff rate is assigned to an accredited installation based on a number of factors including, but not limited to: the technology type the total Installed Capacity (TIC) the installation's position in deployment caps if a solar installation, whether you are classed as a multi-site generator if the installation is a solar installation, whether the generator is classed as a multi-site generator If the installation is a solar installation, whether it meets the Energy Efficiency Requirement (EER) Generators may receive deemed export payments for installations with a capacity of 30 kilowatts or less if an export meter is not fitted. This is where export is estimated as a percentage of the generation meter reading, rather than being based on an export meter reading. The amount of generation which is deemed to be exported is set by the Secretary of State for the Department of Energy Security and Net Zero each year in their annual determinations . Solar PV tariff rates Tariff rates for Solar PV installations are uniquely split into Higher, Middle and Lower bands. The tariff rate an installation receives depends on if the Energy Efficiency Requirement for the building that the installation is wired to provide electricity to has been met and if the owner is classed as a multi-site generator : Higher: An Energy Performance Certificate (EPC) of level D or above was issued before the commissioning date of the installation, and the owner is not classed as a multi-site generator Middle: An EPC of level D or above was issued before the commissioning date of the installation, and the owner is classed as a multi-site generator Lower: An EPC of level D or above was not issued before commissioning This three-band structure only applies to Solar PV installations accredited after April 2012 and does not apply to the other technology types regardless of commissioning date. Tariff table information You can find the full tariff bandings in the Feed-in-Tariff (FIT): Tariff table spreadsheets available below. Following the publication of the government response to the consultation on changes to inflation indexation in the Feed-In Tariffs (FiT) scheme , tariff rates will be adjusted each financial year in line with the Consumer Price Index (CPI). This applies from FIT Year 17. Formerly, tariff rates were adjusted each financial year in line with the Retail Price Index (RPI). If you don’t understand a term being used, please see our glossary .
