Question about annual CPI adjustments
Hi
We're new to the forum. Our air source heat pump has just been installed, and our first quarterly RHI payment is due at the end of April this year.
I've tried to find some guidance on how the annual CPI adjustment is calculated and applied, but all I could find find on the OfGEM RHI site was that an adjustment is made on 1 April every year.
Please could anyone help with any info at all on how the CPI value is derived for the annual adjustment, and whether it is applied to all quarterly payments made following 1st April each year regardless of when the heat pump was registered for RHI.
Any info at all would be greatly appreciated 🙂
