EDAROTH secures BOPAS certification with unique 100-year durability status

Wednesday 18 February 2026

EDAROTH, the social and affordable housing developer wholly owned by AtkinsRéalis, has secured full Build Offsite Property Assurance Scheme (BOPAS) accreditation - including a landmark 100-year assessment for both its house and apartment systems.

This accreditation means EDAROTH is the only provider on the BOPAS Register with housing and apartment products independently validated for a century long service life, setting a new benchmark for quality, resilience and investor confidence in the UK housing sector.

BOPAS is widely recognised as the leading assurance framework for Modern Methods of Construction (MMC), developed with the Council of Mortgage Lenders to provide long-term confidence to lenders, developers, insurers, housing associations and residents. Traditionally built around a 60 year benchmark, BOPAS has expanded its scope to include a 100-year assessment for high performing systems in a category where EDAROTH now stands alone.

Mark Powell, Managing Director of EDAROTH (an acronym for Everyone Deserves A Roof Over Their Head), said: “This accreditation is testament to the innovation and dedication of our entire team over many years. Achieving 100-year durability status for both our house and apartment systems demonstrates the exceptional resilience and quality of our approach.

“For our partners, investors and the communities we serve, this provides the highest level of assurance that EDAROTH homes will deliver long-term value, safety and sustainability and that social housing can be built to the highest standard. It’s a major step in our mission to expand access to high quality, affordable housing across the UK.”

The 100-year accreditation reinforces the robustness of EDAROTH’s hybrid offsite system, comprising precision engineered components which are manufactured under controlled conditions in its factory in Bradford, then transported and assembled on-site ensuring consistent high quality, reduced construction risk and optimal building performance.

In its feedback, BOPAS described EDAROTH’s performance in the assessment as ‘outstanding’, highlighting its ‘robust, fully embedded processes and procedures’ and the ‘strength, maturity and consistency’ of its operational approach which further validates the organisation’s engineering capability and commitment to quality.

For investors and long-term asset owners including housing associations and local authorities, the accreditation provides an unprecedented level of durability assurance. A verified 100 year lifespan significantly de-risks long-term maintenance planning, strengthens lifecycle cost forecasting, and enhances the asset value for institutional investment.

With EDAROTH homes also designed to meet and exceed Future Homes Standards, as well as achieving net zero carbon operational energy performance, the accreditation reinforces its credentials as a future-ready investment proposition.

This milestone marks the culmination of a five year journey, during which EDAROTH worked closely with LRQA to assess and validate its hybrid MMC system. The final step came in December with EDAROTH passing the BOPAS Full Implementation Audit covering project management of design, manufacture and construction.

As the UK focusses on accelerating housing delivery, the EDAROTH approach coupled with its accreditation supports the scaling-up of modern, sustainable homes delivered at pace that address today’s housing shortfall, while meeting the long-term needs of residents and investors alike.
