Hi, I'm same as you, just starting out and in the UK...
I've done a couple of workshops, all good, the CP soaps turned out fine. I've just made my 4th batch of solo CP soap, and this is where it gets interesting...the first 2 seem ok and are curing well, the 3rd was a disaster, and this 4th one, well, let's just say I'm learning from mistakes!
I had this notion that I would be able to just start making lovely CP soap, and then start selling it... I'm quickly finding out that it's not that simple... as well as all the UK legalities (getting recipes certified, getting them on the portal, labelling, GMP, PIFs, insurances, etc, etc), I'm realising that I'm going to have to do a lot of soapmaking and getting it tested in real life by myself and family and friends before I can even think about selling it!
What's more frustrating is the waiting for the CP soaps to cure before they can even be tested - at least with M&P the soap can be used pretty much straightaway.
As far as legalities in the UK, I think M&P is a bit easier, but I guess it depends whether you want the finished product to be your own creation (which I do lol)
So, I'm just going to keep practising, hopefully my soaps will improve
Good luck soaping xx
