Feed in Tariff - Using estimate for calculating what you've earnt.

I've had solar PV since 2014, so quite a good tariff. Aware the annual increase 1 April was 13.4% this year, and with accounting period being 1 March to 1 June, took a reading end of March. It worked out 15% of the quarter was generated in March and 85% April and May. To my surprised, EON.Next estimated that over a third of the total was generated in March, and the remaining 65% at the higher rate. I gave them the exact figures, but so far have not got an amended statement.

If they are doing this to everyone with a FIT, seems we are all being 'short-changed'.

Just wondered if anyone else was receiving such a bizarre 'estimate' as to how much was generated before the 13.4% increase from 1 April. I accept it is not a great amount, but can't see why they should be allowed to get away with it.

    There's a thread on the Green and Ethical forum (start here) where others have contacted EON with their actual end-of-March reading and have had their FIT payments recalculated.
    But you don't need to submit your reading on the 1st of the month. I submit my reading to EON Next late in the month (my last reading was the 22nd of March, my next will be the 20-somethingth of June) so there's a lot less risk of them coming up with a disfavourable estimate.

    I've just checked mine with Eon and they've underestimated by about £10 on the FIT.  I've told them!

    Follow up - Just had an email from Eon issuing a revised FIT statement and a £10 refund on the way!  All in under 2 hours!
