What Offsite Alliance does

Offsite Alliance is a UK-based membership organization focused on the offsite construction and Modern Methods of Construction (MMC) sector. Founded around 2015 by Gaynor Tennant, who continues as Founder and Chair, it convenes construction businesses, building product manufacturers, housing associations, local and combined authorities, contractors, and policy makers under a stated purpose of providing 'insight, influence, and practical support' to members navigating MMC adoption.

The core offering is a Membership Programme bundled with five structured workstreams — Digital Transformation, Technical Solutions, Skills and Competency, Digitalisation, and Design Integration — that translate the membership proposition into delivery engagements. Published resources include the 'From Pilot to Pipeline' report, a Building Capability Toolkit defining 19 Future Occupational Profiles, a Ground Gas Protection Best Practice Guide, and PAS 8700 FAQ documentation. Distribution channels include a Wix-hosted website, an email newsletter, regional events and roundtables, and 'The Ripple Effect' podcast; a 'Sustainable Homes Hub' platform is under development. The organization does not maintain its own proprietary technology stack: the website runs on Wix with Google Analytics, and integrations referenced in member news (e.g., NBS Chorus with Autodesk Revit) belong to individual members rather than to Offsite Alliance itself.

Revenue is generated entirely through recurring subscription membership fees; tiered pricing is not publicly disclosed. Customer acquisition is run as a direct, consultative motion (a 'book a call' website flow) supported by regional in-person events. The organization is privately held, founder-led, reports 1-10 employees, and shows no disclosed funding rounds, parent company, or external investment.

Regional players

• Considerate Constructors Scheme: UK non-profit scheme promoting respectful and considerate construction site practices. Comparable as a UK-centric membership/adherence organisation for the construction sector, though focused on site conduct rather than offsite methods.

Direct peers
