Re audit of LLP

I have prepared accounts for an LLP which turn out to need an audit due to gross assets exceeding the threshold althogh income doesn't. These need to be with Companies House by 31st January to avoid a penalty. I don' t have time to audit them  by 31st January so should I submit non audited accounts in time  and audited accounts later? The members, who are non UK companies, are happy to sign the non audited accounts.
