Help with trading 212 or vanguard.

Hi all! I’m a new and small investor. Currently on £200/ month (150 VWRP 50 Vanguard retirement 2040 fund). This total will go up to £400 a month this year with some work changes and a second job pay improvement. I’ve just been looking into the charges between trading 212 and Vanguard, and is it worthwhile changing to 212 as the fees are cheaper (I can’t find where the fees are, but my current charges with vanguard are estimated at about £50 a year).
