What else do I need to know?

This is a Side letter to a consultancy agreement where the consultant is an individual’s personal service company.  Under the side letter, the individual gives undertakings to the client regarding the personal service company and compliance with the consultancy agreement. This letter is for use in conjunction with a Consultancy Agreement between the client and the individual’s service company.

A Consultancy Agreement may be for the appointment by the client of an individual’s personal service company.  The service company agrees to provide consultancy services to the client, which will be carried out by the individual.

The individual is not a party to the Consultancy Agreement itself, which is between the client and the service company.

To help ensure that the individual will be available to provide the services and responsible for the performance of the Consultancy Agreement by the service company, the client will often require a letter from the individual to the client under which the individual will enter into legally binding undertakings directly with the client.
