Excellent summary from (c) Dave Chaplin below (and I always love his graphics which is also copied here ), well worth a read but remember, specific advice on your exact circumstances and the contract review (as assessment that you haven't laid an implied contract on top of the written version) is essential.

Folks, after 4.5 years since the last update to CEST in Nov 2019, HMRC have made some cosmetic changes and updated their CEST User Manual (ESM11000).
If you have already reviewed CEST and concluded it's not for you - you don't need to reconsider, because nothing has materially changed.
As HMRC have stated: "There is no change to underlying technical principles." This is curious, given HMRC based it's tool on it's view of status in Nov 2019, yet key submissions it made at the Court of Appeal in Atholl House and the Supreme Court in PGMOL failed. (I have copies of all documents in the Atholl case, having worked on it for 6 years.)
The now-settled case law speaks to the two phased way both mutuality and control needs to be dealt with, in conjunction with the contract, against the backdrop of the admissable factual-matrix.
HMRC have republished the underlying CEST Logic here:
https://lnkd.in/gmERHtDQ. Beware, the new s/sheet format is a doozy.
So, what to learn? Well, the clues are in the guidance. But, first, you need to understand that CEST will only give an "Outside IR35" decision if either of the single-factor pre-conditions (see Atholl) for personal service and control are met. Because, if you don't, then HMRC will only give "Outside IR35" in extremely narrow cases, which most hourly/daily paid contractors will never satisfy. You can find this out for yourself by navigating the logic s/sheet.
So, bearing in mind there are certain choices of answers to unlock the "Outside IR35" door, the guidance is now designed to make you never chose the right combination.
Whilst I'm largely in agreement with the HMRC guidance on substitution, it's puzzling why HMRC have not updated their tool to align with it. Bear in mind, that behind the scenes, in case work, HMRC are aggressively challenging substitution claims.
For control, I partially agree with some of the very basic guidance, which effectively says "don't chose answers W, X, Y or Z" - which would lead to "Outside IR35". Again, why not just update the test to align with the new principles that emerged from the Supreme Court in September 2024? FYI, the new principles on control set the initial pre-condition control bar very low, making any reliance on a control pre-condition trigger very risky indeed - unless your contractor is simply selling widgets. Again, behind the scenes in case work, HMRC are aggressively challenging claims of no control.
And what happens with CEST if you follow HMRC guidance on sub' and control? You end up being told "Inside IR35" or "Dunno" (Indeterminate).
Finally... when HMRC come and check your compliance, what is one of the first questions they ask? "Have you used CEST?" Given the above, why would you chose to play that game?
Best of luck everyone.
