Editorial policy
The rules this site is written under: where figures may come from, how they are checked before publication, how they are dated, and what happens when one is wrong.
Sourcing
Rates and thresholds come only from the published pages of the authority that charges the tax: HM Revenue & Customs for Stamp Duty Land Tax, Revenue Scotland for Land and Buildings Transaction Tax, and the Welsh Revenue Authority for Land Transaction Tax. That material is used under the Open Government Licence v3.0. No figure is taken from a commentator, a news report, a professional firm's summary or an earlier version of this site. An announced change that has not been confirmed against the primary government publication is never published as a current rate. No number reaches a page as typed prose: every figure is computed from the committed dataset at build time, so the only way a wrong number can appear is for the dataset to be wrong, which is a single place to check and fix.
Checking and dating
Before publication, a fixture set of 43 cases across all three regimes and every buyer type is re-driven against the three governments' own calculators, and the build fails on any disagreement. Every page carries the tax year it describes, the date the rates took effect, and the date they were last verified against the source. Rates shown across the site are for 2026-27 and were verified on 9 August 2026. When an authority revises a rate, a new dated record is added and the old one is never overwritten, so pages describing an earlier period continue to show the rates that actually applied then.
Authorship and accountability
Content is written and maintained by StampBand Editorial and is not attributed to individual authors. The publisher is Inventum, a company registered in Australia. The site is not affiliated with or endorsed by any United Kingdom government body and does not present itself as one. Where it describes a rule rather than a rate, it reports what the authority's own guidance says and points to it, rather than interpreting a reader's circumstances.
Corrections and independence
Corrections go to support@inventum.com.au. A reported figure is checked against the authority's published table and its own calculator. If the site is wrong, the dataset is corrected, the external check is re-run, and the affected pages are rebuilt with a fresh verification date. Substantive corrections change the page rather than being quietly patched out of sight. The site is funded by advertising, and advertisers have no involvement in what is published, no sight of content before it goes live, and no influence over how the three regimes are described or ordered.
