Thank you for your question.
I presume you are UK resident for tax purposes and that this money has nothing to do with your funds abroad.
If you are receiving money from a family member on a regular basis to support you and your parents, this is not income and is out of scope of income tax.
The amount seems high for monthly support.
To safeguard yourselves, it is adviseable that you have a document prepared confirming the nature and purpose of giving significant sums to you regularly.
This would be helpful in the event there was an enquiry by HMRC requiring to to explain source of funds. Also, this document would suuport and enquiry by the bank in compliance with anti-money laundering regulations.
My aim is to give you a professional service. I hope this is helpful and answers your question.
