These are the direct out-of-pocket costs the innocent party incurs in dealing with the fallout of the breach of its contract and mitigating its loss. So, the £15 commission I had to pay www.wesellanycrappymotor.com to hock off your car for £50; the additional cost of hiring in a last-minute replacement children’s clown when you didn’t show up at the party as you had promised to do.
Again, bear in mind the point is to put the innocent contractor in the position she would have been had the contract been performed. She would not have had to sell that car, so (presuming this expense was fair enough and reasonably foreseeable, determinate and so on) this will be recoverable on production of appropriate receipts.
