I prepare my own company accounts, but I'm looking to remortgage and the lender needs an independent accountant to verify the figures (can be chartered/IFA/AAT). If anyone here would be interested in quoting to do it, please contact me. It's 2 years that need to be done, my understanding is that the lender would write to you asking you to verify the salary and profit figures, so I would provide whatever you wanted to do that (presumably the same information as if you were doing the end of year accounts for us).
I too prepare my own accounts and when I applied for my mortgage I was asked to request self assessment statements from hmrc as verification
Would be happy to help if not -I am AAT qualified
