Is this legal? I sell home brew equipment. One of my customers who bought a wine kit from me asked if I would make it for him to save him the bother? Of course without thinking I said yes, but would need payment for my time. Later on I started to think about the legality of it. I truly will be only charging him for my labour time which will be £15.00. I just thought in the eyes of the law am I seen as selling alcohol?
Accept payment for the wine kit. Then make it and accept payment for doing so. At no point in the process have you actually sold any wine. (You've only sold ingredients).
If you did not tell anyone then they would not know, would they? Anyone can charge whatever they like for their time so you have not sold any alcohol at all. Not fully sure of the legalities of this arrangement but who is to know?
