Taxi written off, full 3rd party liability, they won't cover ins costs of courtesy car

Speak to your Insurance companies claims department and not the hire people.

Yes as part of the claims process where there is expensive hire arrangements, the Insurance companies look at ways a person could have kept costs lower, by asking for all relevant information.  So what you are being asked to provide, appears to be part of standard processes for this type of claim element.

Agree with @Manxman in exile

Not sure what advice was received when a taxi was hired, with the expectation the third party would end up paying. 

In this situation, there will be a worked out agreement as to what the third party Insurers will pay and it will be only be the minimum payable. They won't pay the whole cost of a hire vehicle and the OP will be left owing money.

Agree, you need to ask the question to Aviva.  What happens, if the third party refuses to pay the full cost of the hire vehicle ?   

Ask Aviva to confirm in writing an answer to the above question.
