You should have received an acknowledgement of your application by now. If you are not eligible for the studentship concerned because of your qualifications or nationality then the institution concerned may have a policy of not replying to such enquiries. Sadly, as some people try to use bulk email techniques to find a studentship, UK universities receive very large numbers of such emails and have no time to respond and this can sometime effect genuine applicants.
Write to the university concerned, attaching your original application, to check if they have received it.
