Unfortunately, we cannot give you an exact answer in this situation because word count is not subject to referencing rules.

The rules regarding what is and what is not included in your word count depend from module to module, essay to essay, on the subject area and on the assessment criteria. You should check with your supervisor, or module leader. If they are unavailable, your module guide, or the guidance you were given for your assignment should contain this information.

If your query is urgent, perhaps someone in your School's office may be able to provide some help.
