This should give you three months of free Google One for your personal Google account (100 GB storage, Family Plan Sharing and Google Support). It's focused at Virgin Media customers but this link works for anyone, from what I can see. Remember to cancel after 3 months, otherwise you will be charged £1.59 a month.
