If you sell stuff you make...

[ThisIsNotAIBUPeople]

What do you actually need to have, from a legal perspective? I'm not talking big business, more thinking about selling craft items that I make for pleasure, probably no more than a couple of hundred quid a month. I am completely clueless, any advice for idiots beginners very gratefully received.

Depends a lot on what you’re making.

There are lots of companies who do insurance for small crafty type businesses.

Other products have other requirements (especially toys / things for children, anything you consume, etc)

Depends what you are making.
I have public liability insurance.
I steer clear of edible items, cosmetics, stuff for children. Any item used on the skin.

Public liability insurance. I think it’s called the market traders association that do it for £50 ish a year and artists network is about £36 a year

You also have to register with hmrc as a sole trader if your turnover is more than 1k per year
