Advertising disclosure

Last updated 27 September 2026 · Publisher: Rodway Labs

Project Cost Lab may display third-party advertisements, including through Google AdSense (publisher ID pub-7612291779397704). Revenue from ads helps keep the calculator and guides free to use.

How we place ads

• Ads are labelled (for example “Advertisement”).
• On calculator and guide pages, ad units sit after the explanation of the range — not in place of the range and never styled as a contractor price or tender figure.
• We do not put ads on a page that is only a number with no context.
• The mid figure on this site remains a planning band, not a quote — whether or not an ad appears nearby.

Independence of ranges

Compiled cost bands and calculator outputs are editorial illustrations from Rodway Labs. Advertisers do not set our mid points, regional factors or VAT display options. We are not a contractor, architect or quantity surveyor, and ads do not change that.
