I’m getting a relatively small payment (£1000) for my 18th birthday and I’m looking to invest it. How do I do that safely?

As the title says - for my 18th birthday I’ll receive just over £1000 from a car crash I was in as a child. I want to invest it safely. It may seem like a small amount, but I’m fine with small returns. I’d rather invest it and get small returns than blow it in a few days.

Some people have suggested online trading apps, others suggested contacting my bank and talking to them about investing. From what I’ve seen on YouTube and stuff this seems like a relatively small amount of money to invest but I’m not sure how realistic those videos are. Any advice would be appreciated.

I’m in England if that changes anything.
