The first Notice of Intended Prosecution (NIP) and request for the driver's details goes to the Registered Keeper (RK). It is only this NIP that is subject to the 14 day rule. There is no time limit on subsequent NIPs (in fact they are not even legally required though they are almost always provided) and no time limit on any of the requests for driver's details (including the first one). The RK may be your employer or it may be a leasing company from whom they lease the vehicle. If it is the latter the lease company will nominate your employer (because the lease company would not know who was driving) and it would be up to your employer to name you. Both of them have 28 days to respond so it could be up to two months before a NIP and request for your details is sent to you, though usually companies turn such requests round pretty quickly.
