What FIT payment changes mean for you
Find out what the change from RPI to CPI means for your earnings.
You might have seen in the news that Feed-In Tariff payments are changing. In this article, we explain what the planned changes means for your FIT payments and how you can earn more from your solar panels.
What’s happening to FIT payments?
If you receive FIT payments, you’ll know that your generation and export payments rise with inflation every year. Since the scheme began, these increases have followed the Retail Prices Index (RPI), which was 4.2% in the 12 months to December 2025.
From 1 April 2026, annual FIT payment increases will instead be linked to the Consumer Prices Index (CPI). This inflation index usually rises more slowly – 3.4% in the 12 months to December 2025. This change is part of the Government’s plan to help lower energy bills, as FIT is funded through levies on bills, and it will be reflected from your September quarterly payment.
During consultation, the Government considered several ways to reduce the cost of the FIT scheme, including freezing payment rates. That didn’t happen – which is good news for households generating renewable energy – because your payments will still continue to rise each year, although at a slightly slower rate.
How does Good Energy support FIT customers?
We made our voice heard during the Government’s consultation on these changes, sharing our concerns about the timing, process and wider implications for renewable energy investment in the UK.
Our aim has always been to help you get the most from your renewable energy system. One way to do that is through joining Solar Savings, our export tariff open to FIT customers and SEG customers alike.
By switching to our export tariff, you can earn a higher rate for your exported electricity than you get on the FIT scheme; all while protecting your generation payments. This can make a real difference to your overall earnings.
While the way FIT payments increase is changing, you can be reassured that your payments will still rise each year. As your FIT provider, we’ll keep you updated about any policy changes, and share tips on how to get the most from your solar panels.

FAQs
From 1 April 2026, annual Feed-In Tariff (FIT) payment increases will be linked to the Consumer Prices Index (CPI) instead of the Retail Prices Index (RPI).
The Government has argued that RPI overestimates inflation and increases the cost of the FIT scheme. Because the scheme is funded through levies on electricity bills, they hope the switch to CPI will reduce the overall cost of the scheme, while still giving generators fair inflation protection.
Your FIT payments won’t decrease, but future annual increases are likely to be smaller, because CPI is typically lower than RPI.
The Government states this is not considered a fundamental change. Indexation remains in place, via CPI rather than RPI.
Yes. Both generation and export tariffs will be indexed by CPI.
The new CPI based indexation will apply from 1 April 2026. This will be reflected in your September quarterly payment.
The Government has moved the publication date for the new FIT tariff rates from 1 February 2026 to 1 April 2026. This delay is temporary; from 2027 onwards, the 1 February publication deadline will resume.
