The minimum tuition deposit required by UK universities can vary significantly depending on the university and the specific course. However, as a general guideline:

- Most UK universities typically require an initial tuition deposit of around £2,000 to £5,000 to secure your place and to issue the Confirmation of Acceptance for Studies (CAS) letter, which is essential for your UK student visa application.
- Some universities may require a higher deposit, especially for postgraduate or high-demand courses.
- The deposit is usually part of your total tuition fee and will be deducted from your first-year payment.

Important:
- The exact deposit amount and payment deadline will be specified in your university offer letter.
- Some universities may offer flexibility or payment plans for the remaining tuition fees after the deposit.
