BOPAS scheme

Recognised assurance for innovative construction

Helping prove new methods will stand the test of time.


BOPAS is a risk-based assessment that demonstrates to lenders, buyers, and other stakeholders that homes built using modern methods of construction (MMC) or non-traditional materials will be mortgageable for at least 60 years.

Together with our partner, BLP Technical Services, we assess MMC providers through:

  • Evaluation of the construction system, and
  • Resilience testing of systems, processes, and competencies from concept through to the handover.

Backed by the industry

The scheme was developed by Buildoffsite, The Royal Institution of Chartered Surveyors (RICS), LRQA and BLP, in consultation with the Council of Mortgage Lenders (CML) and the Building Societies Association (BSA).

The scheme aims to standardise best practice across the MMC sector. It focuses on ensuring that accredited organisations have robust systems and procedures underpinned by a risk-based approach that enables them to competently, and safely deliver products or services that meet their clients’ requirements.

Benefits of using BOPAS

  • Provides assurance that delivery is through defined processes that meet best practice
  • Processes and work controls across the supply chain are synchronised with each member working together with common aims, methods, and objectives
  • Risks to the project are evaluated and mitigated

What is BOPAS+?

BOPAS+ has been developed to put the focus on the preparedness of MMC providers to positively address the digitisation challenge presented by the net zero initiative, the golden thread, and regulation changes.

It has been through a rigorous validation process involving three BOPAS accredited organisations, which have developed a clear line of site between their strategic objectives, operating plans and schedules, and their digital goals.

The digitisation maturity model is presented as a radar map that shows the scores achieved and will appear on the BOPAS website against that respective MMC provider.
