Feed-in Tariffs Annual Report: Scheme Year 15 April 2024 to March 2025

Launched in 2010, the Feed-in Tariffs (FIT) scheme was designed to promote the uptake of small-scale low-carbon electricity generation. The FIT requires participating electricity suppliers to make payments to eligible small-scale generators for the generation and export of electricity to the grid. Through this, the FIT has subsidised the deployment of low-carbon generation technologies within households, businesses, organisations and communities, supporting the development of a flexible, affordable and net zero energy system.  

The scheme closed to new entrants in 2019. However, the scheme remains active as accredited installations can receive FIT payments for up to 20 years.  

This annual report provides an update on FIT scheme activity during Scheme Year 15 (SY15), covering the period 1 April 2024 to 31 March 2025. It provides information on the installations registered, the electricity generated and exported, the associated payments made, the scheme’s costs, and our compliance and administrative activity. 

Highlights 

FIT installations 

• At the end of SY15, there were 869,659 installations accredited on the scheme with a total installed capacity of just over 6.49 GW. Overall, 99.56% of FIT installations are solar photovoltaic and 95.38% are in domestic settings.
• Micro scale installations (capacity of 50 kW or less) account for 99.20% of FIT installations and 53.75% of installed capacity. Rooftop solar panels make up the vast majority (99.28%) of these smaller installations.
• Amongst larger installations (capacity above 50 kW), solar PV is still the most common technology, accounting for 57.46% of capacity. Other technologies include: wind (23.95% capacity), anaerobic digestion (10.06% capacity) and hydro (8.53% capacity). 

Renewable generation and scheme costs 

• During SY15 nearly 8.0 TWh of renewable electricity was generated, for which FIT generators were paid just over £1.73 billion. Of this generated electricity, 1.5 TWh (18.8%) was exported to the grid, with associated export payments of around £94.1 million. Total FIT payments therefore reached £1.83 billion.
• In SY15, generation fell by around 0.37 TWh (4.5%) from SY14 levels and the total value of the scheme decreased by £14.1 million (0.8%) to almost £1.84 billion.  

 Monitoring compliance 

• We operate robust audit and compliance programmes to ensure that suppliers are fulfilling their obligations and payments to generators are only made against eligible generation and export. We reserve the right to pursue compliance and enforcement action when participants fail to comply with scheme rules.
• In the SY15 levelisation process, 8 suppliers submitted their data late and there were 150 incorrect data submissions. Additionally, there were 6 late levelisation payments totalling £5,326,765. Ultimately, none of these payments were left unpaid and mutualisation was not triggered.
• We closed 102 compliance investigations looking at FIT generators in SY15. Through this, we successfully identified just over £430,000 of error and suspected fraud. Of this, we prevented £386,753 being paid out incorrectly and we detected a further £43,057 that was paid to generators who were not eligible to receive it. We apply robust safeguards to stop incorrect payments and take decisive action to recover funds from those not entitled to receive them.
