What suprises me about this case Chris, is that your IP does not seem to be remotely interested in listening to your points - and trust me you have a basket of good ones for the ombudsman or anyone else to have a go at.
In principle there is nothing wrong with a professional charging fees on the basis of time costs - I also use this measure for my bankruptcy and liquidation work. However, yours is a case with a difference, and you do keep finding issues (from the IP's own paperwork) which are incriminating. I do wonder if the IP knows that a member of his staff has sent you those time records? I suspect not.
As I have said earlier, there are always two sides to a dispute, and you are adult enough to recognise this. Also, given Lily's long winded experience with another ombudsman, you must bear in mind that there may not be a quick solution to this issue. Why don't you send a final letter to your IP, cc'd to the ombudsman and his regulatory body, advising that you are prepared to accept 1.5 times his original fee estimate in view of the additional work you recognise he had to carry out with regard to HMRC.
My thoughts are that it is a brave IP who fails to accept this - especially at a time when IP fees are under such public scrutiny. If accepted, then the remaining money you have paid over should cover the amount you are still due to pay. Can you do those sums for me just to check?
