Investment tips for a 17 year old earning £22,000 a year

Hi all,

I’m 1 and 1/2 years into a 4 year cnc machining apprenticeship.

I’m comfortably saving £800-£1200 a month and have been placing it into premium bonds (£10,500 saved) currently, as a lot of banks with good interest rates require you to be 18.

I’ve had no luck with premium bonds really and I am looking to place my money elsewhere (investing!)

FYI I turn 18 in 2 months, so I will be open to a lot more opportunities.

Where should I start? Any and all advice is appreciated 🙏
