Specification Online

What Specification Online does

Specification Online is a UK B2B trade media platform serving architects, building product specifiers, contractors, and building product suppliers. Operated by TSP Media, a privately held UK company headquartered in Telford, the business originated as a construction and building news magazine in 1996 and has since evolved into a digital multimedia publishing platform that aggregates industry news, product specifications, technical documentation, case studies, CPD courses, webinars, and video content for the UK construction industry.

The platform is built as an integrated content ecosystem with several core modules: a Building Product Library of supplier brochures and technical literature, a Specification Product Directory organised by category and manufacturer, a CPD and Webinar Directory covering technical topics such as render systems, acoustics, and building regulations, and a Construction Videos hub for product demonstrations and case studies. Distribution is digital-first across the main website and six sector-specific ebulletins (Specification Ebulletin, Specification Product Update, Housing Specification, Hotel Sport and Leisure, Public Sector, and Education), supplemented by print publications including Specification Magazine, Housing Specification, and Public Sector Building Specification, an editorial sub-brand called Let's Talk Specification, and active social media profiles on Facebook, X/Twitter, LinkedIn, and Pinterest.

The business model is advertising-led. Revenue is generated through media pack placements sold across the website, ebulletins, and print publications, with pricing not publicly disclosed. The customer base consists of UK building product suppliers and manufacturers who buy advertising, directory listings, video features, and CPD placements to reach specifiers and contractors, alongside housing developers and contractors featured in case studies. No API, mobile app, integrations, AI features, or external funding have been disclosed, and the company has not reported revenue, headcount, or ownership structure beyond its UK private limited company status.
