Planning to start selling soap from home

Hello. I'm planning on making soap at home and selling it. This will be on a very small scale (probably 15-20 bars of soap a week), and most of the manufacturing will be done from my kitchen. What licences will I need to get before I begin selling? Also, are there special conditions that I need to fulfil (floor space, for example)? Would it be wrong to sell the soap to friends without a licence?
