Given that the approved repair company is, as it says, approved (by the insurance company), then you should assume that all repairs will be completed to a good standard. In the first instance, you should (when the car is ready for you to collect) ask the repair company for a list of all work completed. Then you yourself should be able to inspect all paintwork/trim/etc to see if it's acceptable. One note; when checking the paint work, stand quite a way back from the car at first so you can see the resprayed area v the original. Do take your time when collecting the car (take a friend with you).

Having accepted the car you could, if you wish, arrange for a independent inspection (taking into account the cost). Or you could wait until the next time you take your car to your Ford dealership for service and ask them to check the car out (this should not cost you). Overall, most insurance companies have "approved" repairers who are acknowledged as experts in crash repairs and complete the job correctly.
