Industrial and Provident Society - report (non-audit)

I ahve taken over acting for an I&P soc. the members have opted out of audit. I think the style of report on the previuos set of accounts is incorrect. Am I correct in saying that under £90K there is no stipulated report, so just use ICAEW approved small company report? Also if the T/O is over £90K, is the old style compilation report still the one to use? Many thanks.
