Hi, having not worked for a while I have been offered a couple of days consultancy work through personal recommendation. I have never done any independent consultancy or been self-employed before so would appreciate a steer on anything to watch out for. In particular if I need any insurance. I have no plans to do this on anything other than an ad hoc basis so don't want to overcomplicate things - or incur costs which negate the financial plus of a day's work. Any advice much appreciated!
