This page explains how we research, write, and verify content on evtariff.co.uk. We publish our methodology because the value of the content depends on whether you trust the process behind it.
Our editorial approach
We write from a research-led editorial perspective rather than claiming first-party hands-on experience we don't have. For EV-tariff and grant claims specifically, we cite OZEV, DESNZ, and Ofgem primary sources, and verify supplier rates against the live tariff pages at the time of publication.
For every recommendation, we cite the source: independent published reviews, manufacturer specifications, regulatory filings, peer-reviewed research where relevant. If we can't verify a claim, we either omit it or label it explicitly as speculation.
What we will and won't claim
We will cite specific independent reviewers, manufacturer documentation, and primary research where relevant.
We will distinguish between confirmed facts, manufacturer claims, and our editorial inference.
We will update articles when new information lands and note the refresh cadence in the editorial footer.
We will not claim first-party testing or hands-on experience we haven't done.
We will not fabricate statistics, study results, or testimonials.
We will not hide affiliate relationships - every affiliate link is disclosed (see Affiliate Disclosure).
AI-assisted research
We use large-language-model tools as part of our research workflow - primarily for summarising published evidence, drafting outlines, and cross-referencing claims against authoritative sources. Final editorial judgment, source verification, and the published prose are human-supervised. See our AI Use Disclosure for the wider position.
Source policy
We rank sources roughly as follows when assessing claims:
- Primary research - peer-reviewed studies, government publications (e.g. .gov.uk, .gov), standards bodies' documentation.
- Manufacturer specifications - product datasheets, official policy pages, regulatory filings.
- Established independent reviewers - long-running outlets with a public editorial methodology of their own.
- Community signal - aggregated patterns from forums, customer reviews, and trade press. Used for triangulation, not as standalone evidence.
Where sources conflict, we surface the conflict explicitly rather than picking the more flattering claim.
Update cadence
Reviews and comparisons are refreshed quarterly or when meaningful new product information lands. Industry-analysis posts refresh on major events (new product launches, regulatory changes). Each article carries its most recent refresh date in the editorial footer.
If you spot a factual error, please flag it via our contact page - we correct quickly and disclose the change.
