No, once you have purchased a course you will have access to it for as long as it is published on the LawCPD website. This includes any updates made to the online CPD course after it is published.
This means you can purchase an online legal CPD course today, then complete it in a week or even a couple of months time. For example, you could purchase an online CPD course in one CPD year, then complete it in the next one (if you already had enough points in the current CPD period). It also means you can purchase online CPD courses during special offer periods then complete them later.
