The Build Offsite Property Assurance Scheme (BOPAS) is an industry-leading accreditation scheme underwritten by RICS, Buildoffsite, Lloyd’s Register and Building LifePlans.

The Build Offsite Property Assurance Scheme (BOPAS) is an industry-leading accreditation scheme underwritten by RICS, Buildoffsite, Lloyd’s Register and Building LifePlans. It guarantees a product’s consistent through-life performance that it will remain saleable and insurable for a minimum of 60 years (more than three times the term of many mortgages) and provides assurance against any form of variability in the system or product warranted.
Developed in consultation with the Council of Mortgage Lenders and the Building Societies Association, BOPAS presents the gold standard for novel offsite construction techniques.
It comprises:
A) An appraisal of durability and maintenance.
B) Process accreditation
C) An online database of assessed building methodologies, registered sites and warranted properties.
Additionally, it is designed to evaluate the adoption of best practice by offsite constructors in competency, configuration, risk, and procurement management and process control.
