I'm going to answer my own question

I phoned SSE this morning - they are still taking calls to the microgeneration team (I think someone on another thread said they were not). Spoke to a very nice lady who said they had literally just finished emailing out reading requests for the 2nd quarter. Any email addresses which had been bounced would be sent a letter in the next two days. Whilst on the phone the email appeared!!!
So now to fill it in and await another cheque
