Sources
We use primary sources wherever they exist: government and local authority publications, the Environment Agency, official statistics, recognised research bodies and manufacturers' technical documentation. We cite sources beside the claims they support. Where we use a manufacturer's figure, we say so, because one system's specification may differ from another's. We do not use competitors' marketing as evidence.
What we will not publish
- Statistics we cannot trace to a named publisher
- Reviews, ratings, accreditations or installation counts we cannot evidence
- Guarantees or promises on behalf of installers
How content is written and reviewed
Guides are drafted by our editorial team, which may use AI tools to help with research and drafting. Every page is checked against its sources by a person before publication. Factual claims about planning, drainage and specifications are worded carefully, because the right answer for a particular property depends on a site assessment.
Dates and updates
Each guide shows when it was published and, where relevant, when it was last substantively updated. We do not change dates without changing content. Pages on planning, costs and data are reviewed at least every six months; other guides at least annually.
Corrections
If you find an error, email hello@guildfordresindriveway.co.uk. We correct factual errors promptly and record material changes on research pages.
Commercial relationships
We are paid by the installers we introduce. Guides are written to help homeowners judge any quotation, including the one we introduce, and do not favour particular products or firms.
