Hello, I am Keith, one of the experts on Just Answer, and pleased to be able to help you with your question.
The VAT Turnover Threshold is currently 83K in any one year. You would appear to be below this limit so you need not worry about VAT registration. As far as I can see your supplies could never be classed as exampt, but until you breach the turnover threshold you have nothing to worry about.
I do hope that I have been able to set your mind at rest on this matter.
