RetrofitOS Achieves Constructionline Gold

Strengthening our position as a trusted partner for large-scale retrofit delivery

RetrofitOS is proud to announce that we have achieved Constructionline Gold membership, marking another important step in the continued growth and development of the business.

Previously accredited to Constructionline Bronze, our progression to Gold as RetrofitOS reflects the enhanced governance, compliance and operational standards that now underpin our work across the retrofit sector.

Constructionline Gold is independently verified against the Common Assessment Standard and demonstrates that a business has successfully completed enhanced checks across a wide range of areas, including health and safety, financial standing, environmental management, quality management, corporate social responsibility, equal opportunities, modern slavery and anti-bribery.

What this means for our clients and partners

For our existing clients and delivery partners, achieving Constructionline Gold provides further independent assurance that RetrofitOS has the controls, policies and operational standards required to support complex, regulated and large-scale retrofit programmes.

We already work alongside Tier 1 contractors, housing providers, local authorities and retrofit delivery organisations across the UK. This accreditation further strengthens those relationships by validating the standards our partners expect from a trusted technology, compliance and delivery provider.

It also supports organisations looking to engage with RetrofitOS through their own procurement and supply-chain processes.

As a recognised pre-qualification standard across both the public and private sectors, Constructionline Gold can help reduce repetitive procurement requirements and provide buyers with a trusted, central point of reference when assessing potential suppliers.

Supporting delivery at scale

Large-scale retrofit requires more than individual services or standalone technology.

It requires robust governance, clear accountability, effective risk management and the ability to support multiple organisations working together across complex programmes.

RetrofitOS has been developed to help contractors, housing providers, local authorities and their wider supply chains manage retrofit delivery more effectively, bringing together workflow management, compliance, reporting, consumer protection and project oversight within one operating system.

Achieving Constructionline Gold reinforces our commitment to building a business that can support that delivery at scale.

It demonstrates that the standards behind RetrofitOS extend beyond the platform itself and into the way the company is managed, governed and operated.

The next stage of our development

The move from ECO Surv to RetrofitOS represents more than a change of name.

It reflects our wider ambition to provide the operating system needed to support safer, more efficient and more transparent retrofit delivery across the UK.

Constructionline Gold is another important milestone in that journey and further strengthens our position as a trusted delivery and compliance partner for the sector.

We look forward to continuing to support our existing clients, building new partnerships and helping organisations deliver high-quality retrofit programmes at scale.

Verified. Trusted. Built for delivery at scale.
