Transparency about how the numbers on the data page and directory are produced.
The public GOV.UK “find an EV chargepoint installer” / OZEV authorised-installer tool, reused under the Open Government Licence v3.0.
The tool is queried across a UK-wide postcode grid; only installers offering commercial work are kept. Requests are rate-limited and polite. Re-run automatically every week.
Records are de-duplicated on a normalised name + postcode key; collision-safe page slugs are assigned at build.
Scraped personal (firstname.lastname) and free-webmail email addresses are not published as links — a privacy choice, documented on the privacy page.
Fields that aren't in the source are shown as “Not listed”, never guessed. Data reflects the source on the last refresh date shown; always confirm with the installer before contracting.
The derived statistics are free to reuse with attribution under the OGL v3.0. A suggested citation is on the data page.
