Buildoffsite

What Buildoffsite does

Buildoffsite is a UK member-based industry network that promotes the adoption of offsite construction techniques and modern methods of construction (MMC) across the built environment. Founded in 2003 and headquartered in London, it operates as a branded network wholly owned and managed by CIRIA Limited (a member-based construction research association incorporated in England and Wales, registered number 00790505). The organization serves clients, contractors, designers, manufacturers, and suppliers in the UK construction sector, alongside government departments, local authorities, and policymakers involved in housing delivery and construction regulation. Its membership base includes over 50 organizations spanning the industrialised construction value chain.

Buildoffsite's core product offering is the BOPAS (Buildoffsite Property Assurance Scheme), a risk-based certification developed in collaboration with RICS, LRQA, and BLP that provides lenders and purchasers with a 60-year durability guarantee for homes built using modern systems, addressing mortgageability concerns. Additional offerings include an annual membership program (with subscription tiers tied to organization size/turnover and a minimum one-year term), CPD-accredited events including the Explore Offsite Conference and BOPAS Forum, sector working groups (Transport & Infrastructure, Utilities, Commercial & Social Infrastructure), and publications such as guidance documents on performance specifications and intellectual property management for MMC projects.

Revenue is generated through recurring annual membership subscriptions supplemented by ticket sales to events and revenue from publications. Buildoffsite operates with a very lean headcount (1-10 employees) since operational management, including website, membership administration, events, and publications, is handled by CIRIA. Go-to-market is community-led, leveraging the website, a monthly e-newsletter, events, sector working groups, and direct government and policy engagement to influence MMC adoption.
