Our standards
- Answer the question first. Every guide starts with a direct answer, followed by the detail that supports it.
- Primary sources. Prices, incentives, regulations and statistics come from official bodies, regulators, standards or manufacturers’ technical documentation wherever possible. Each figure is linked to its source with the date it was checked.
- No invented numbers. If we cannot verify a figure, we do not publish it as fact. In calculators, unverified values are labelled as examples so you can replace them with your own.
- Local, not translated. Each country edition is researched separately for currency, units, regulations and the terms people actually use.
- Dates. Articles show when they were last updated. We review pages when prices, rules or incentives change.
Safety-critical topics
Electrical work, gas, structural changes, roofs and working at height can be dangerous and are regulated differently in each country. Guides on these topics carry a clear safety note, explain when a qualified professional is required, and are reviewed before publication.
Use of AI tools
We use AI tools to help with research summaries, first drafts, translation checks and illustrations. A human editor reviews and edits every article before it is published and is responsible for its accuracy. AI tools are not used to invent sources, prices, quotes or expert opinions. Images created with AI are labelled as such and are never presented as photographs of real projects.
Independence
Advertising pays for the site, but advertisers do not see articles before publication and have no say in what we write. We do not accept payment for positive coverage.
