Each local authority will decide what evidence of student status it needs. If you are required to provide evidence of your status, your institution must provide you with a Council Tax certificate (usually a printed statement), free of charge, confirming that you are a full-time student or student nurse. The local authority will usually accept this.
You may be refused a certificate if you ask more than one year after you have finished your course, as there is no legal duty for your institution to supply such a certificate, although many will continue to do so.
Some local authorities have online forms for you to complete, and may have arrangements with local colleges and universities to verify a student’s status directly, rather than relying on the provision of a certificate, so it is advisable to check your local authority’s website for its procedure. Find your local authority.
Although your institution may be required by law to provide you with a certificate, a student certificate is not required in order for you to qualify for a discount, and information in an alternative form from your college or university should be deemed to be satisfactory evidence. However, if you do not provide information in the format of a certificate, your local authority may not accept this and you may need to challenge this by appealing.
If you are a foreign language assistant and therefore not following a course of study, the fact that you are registered with the British Council and are appointed to an institution should be sufficient evidence of your status.
