Ofgem have at least finally agreed to re-rate my installation to 15kw - this brings to mind some thoughts on TIC, best in a new thread.
But regarding the subject of this thread, Ofgem are still denying any responsibility. However looking at the ongoing DECC FITs consultation:

"We are in part seeking general confirmation of the features of the FITs scheme as it currently operates. However, a number of issues have arisen in the administration of the scheme for which we propose to consult on changes. These are:
• to allow for preliminary accreditation of installations so that investors can be sure of how they will be treated in terms of factors that potentially affect which tariff band they are allocated to e.g. definition of site, multi-installations,"
it seems that DECC are taking steps to avoid (blame for) the very situation that I am in.
I know that DECC is not Ofgem but they are kissing cousins.
