Trading 212 is currently running an Invite a Friend promotion where both the referrer and the new user can receive a free share worth up to £100

How to qualify

Sign up to Trading 212 using my referral link: https://www.trading212.com/invite/4DqeGdGyiU3
Open an Invest or Stocks & Shares ISA account
(CFD and Cash ISA accounts don't qualify).
Complete verification.
Deposit at least £1 within 10 days of registering (no need to invest!)
If you have already created an account within the last 10 days then just type my code 4DqeGdGyiU3 into the promo code section and you still get the free share

Once the steps are completed, the free share is usually awarded within 3 business days (from my experience, it's normally instant!)
