UK CBAM starts in January 2027. Much of it is still being written.

The UK mechanism begins on 1 January 2027, and the instruments setting it up are being made now — administration, the rate method, carbon price relief, transitional deadlines. Several are already law. Several are drafts waiting on approval or on notices nobody has published yet.

That is an awkward period to plan in, because the rules that will bind you exist in pieces. Every article here links the instrument it rests on and says whether it is in force or still a proposal. Where the EU regime interacts with the UK one, we cover both.

Every figure has a date

Certificate prices change every quarter and the rules are still moving. A figure always names the quarter or the version it belongs to, so you can tell whether it still holds.

Drafts are called drafts

Much CBAM guidance is still a proposal. Where that is the case, the sentence that makes the claim says so, rather than a footnote at the bottom.

Every claim has a source

Each article links the regulation, factsheet or study it rests on, and says which kind it is: law in force, official guidance, or research that only points a direction.

The people who will run UK CBAM are being trained now.

A regime that begins on 1 January 2027 has to be operated by somebody from the first week. Reading the instruments as they appear is how you follow the rules; it is not how a team learns to run a return under them.

CBAM.School's UK track covers the mechanism from the importer's side — scope, data, the return, and where the EU and UK regimes diverge — and it opens with the regime rather than before it, because we will not sell a course on rules that are not final. Leave an address and we will tell you when enrolment opens.
