I did try again later and then got the email again to say the transfer could not be completed.
The balance in the utilita app has not changed but on my in home monitor, my balance on electricity has decreased by £125 the amount of the two transfers.
So if the transfers have not gone through when my electricity balance will be corrected on the in home monitor, I can't check the app balance because it's never correct and sometimes doesn't have the right balance for over 7 days.
I've tried waiting on live chat but no response after over an hour.
