NEC3 ECC Option C contract. We are the Contractor and have travel expenses costs (flights etc) that are backed up by invoice evidence. The client is making his own assessment/disallowing some of these travel costs on the basis that e.g. 'you could have purchased that flight for ‘£200 rather than the £400 you paid’. Can the Client do that? ---

Only if they can prove at the time that you could have purchased a comparable flight at the time for £200 (and not a cheap one via Brussels and then Amsterdam before a third stop over in Paris). Probably hard to prove, and you would like to think that you would not have booked a £400 flight when a £200 one was available. If we were talking the difference between 1st and 2nd class then they would have a point, but I assume you are not here. It is a bit like buying materials for a CE more than at market rates. They could assess it at what would have been open market rates at the time.
