A readiness tool for the importers CBAM actually lands on
UK CBAM Report answers one question for a small or mid-sized importer: does the new carbon border charge catch me, when, and roughly how much. It is built for the businesses the big carbon-accounting suites do not serve.
Who this is for
If you import iron and steel, aluminium, cement, fertiliser or hydrogen goods for commercial purposes, or you buy them as inputs, CBAM is your problem from 1 January 2027. The enterprise carbon-accounting vendors chase large-tonnage clients with subscription platforms that are overkill for an importer bringing in a few containers of steel fixings or aluminium extrusions. That importer still has to work out whether the £50,000 threshold catches them, when they must register, and what the charge might be. That gap is what this tool fills.
What you get
A free scope check against the £50,000 threshold with an illustrative cost band, and a paid personalised report (£39) that gives your in-scope answer, your exact registration and return dates as a dated checklist, an estimated cost with the method shown, a checklist of the supplier emissions data to start collecting now, and a status box of what is confirmed versus still in consultation, each with a gov.uk source.
How we stay current
CBAM is a moving target. The policy architecture is settled, but the numbers you multiply, the final commodity-code list, the per-good default emissions values, the quarterly rate, and the exact 2028 deadlines, are still landing through secondary legislation during 2026. The CBAM Rulebook Status board tracks that publicly, row by row, dated. When HMRC publishes the official default values and the first rate, we update the estimator in one place and re-date every figure. Keeping this current is the product, not a footnote to it.
What we do not do
We do not invent numbers. Where an official figure is not yet published, the estimator shows a clearly labelled placeholder or illustrative value and says so, rather than presenting a fabricated number as HMRC's. We are an independent educational tool, not affiliated with HMRC, and the report is general information, not tax or legal advice. Only HMRC guidance and the enacted legislation are definitive, and for a decision that turns on your specific facts you should take professional advice.
