Authority is anchored solely to the Gas Safe registration number, but there is an expert footprint gap as no individual team members are named or linked via Person schema. The presence of ‘Adrian’ and ‘Martin’ in testimonials without professional titles or digital footprints leaves the ‘expert’ claims unverified. The technical implementation is undermined by the entity name mismatch in the structured data, suggesting a template-level error.

The marketing tone makes bold claims such as ‘getting it done right the first time’ and ‘unparalleled drainage services’ without providing case studies or specific metrics of success. There are no mentions of ‘increased energy efficiency by X percent’ or ‘completed over X boiler installs,’ which would bridge the gap between marketing claims and proof. The site relies on the 2010 founding date as its primary surrogate for performance data.

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.
