Record management fee vat portion of an income.

Hi, I’ve been on the chat line to resolve this issue, but the advise I received saw the vat records add my non vat-able rental income as a vat-able income.  I receive an income from a property each month, this is part of our business, it’s taxable but NOT vat- able, there is however, lumped in the amount I receive a 12% management fee from the rent collecting agency, this has a vat amount on it that I’d like to claim back, how do I record the rental agency, and how do I then split or record the agency fees and the vat portion of the income as shown in my bank statement? Thanks
