So I think it’s fair of me to let you know what my final decision was. After reading all your great advice I ended up going with the Trading212. The main reason was the free ISA account, which comes with a fee on Freetrade. Thank you all for sharing your advice and patiently answering my questions.
This feature is pretty cool. Didnt decide based on it but definitely find it useful.
I hope you used some referral to sign up!
Why would he?
Because you get a free between £1 - £100 for doing so. 
(Nudge PM for referral)
So whilst not worth creating an account just for that free cash, it’s a nice cherry on the top if you are looking at upgrading and getting a better broker than say Freetrade. 
(I have Freetrade but to be honest the pink does nothing for me in the same way I prefer Starlings interface. I want my bank and broker to be functional and give me all the tools, not just look pretty and have wiggly charts, that doesn’t help me make money)
Right, I get ya now. An added bonus. Its something I’ve been thinking about personally but still on the fence at the moment as its something I want to do to plan for the future but not sure if I can really spare the capital each month at the moment.
If you are not really sure then I wouldn’t tbh.
Put that in a savings pot instead each month, and build it up. Then take another look in 6 mths.
The key thing is not to play with cash that you may need short term. Ideally have no debts and an emergency fund of savings.
If you still wanted to invest you could open an account and choose something like a world ETF which is lower risk, lower return. So you would be getting better than interest. And start by just setting a automatic deposit of like £20-£50 a month and building from there.
I have no debts, just don’t earn much…£150-£200 a week depending on availability of hours.
