Should I take the maintenance loan?

I have around £13,000, mostly invested in the S&P and use a bit of it to trade stocks. Most money I spend is on travelling and fuel. £30 goes out each month for gym, paid off 1 year’s car insurance in December. I owe £1800 in April, the last instalment for some student accommodation.

My question is, I am entitled to £3500maintenance loan, should I take it? Or would it not be worth it. I’m obviously on plan 2. What are your thoughts? Thanks
