Identity & Authority — The Lens

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Authority is well-established through organizational transparency, naming specific staff such as Richard Moncur (Renewables BDM) and referencing SNIPEF and Homes for Scotland memberships. A minor gap exists in the absence of Person schema for some named case study installers, though the level of detail provided (e.g., Mark Rolfe, Marshall Heating Ltd) provides sufficient manual verification paths.

Performance claims are consistently anchored to technical metrics or regulatory schemes. The claim of ‘Incredibly efficient’ for oil boilers is immediately followed by a 94.5% efficiency rating and a technical explanation of condensing technology. The HVO biofuel claims cite a specific ‘88% net carbon dioxide emission’ reduction, demonstrating a tight link between marketing and physics.

Identity & Authority is read from the structured data first: whether the site declares who it is in machine-readable schema, with verifiable identity links. Below is the schema captured per page, then the external proof links that support (or fail to support) that identity.
