The Framework That Sets Us Apart:

Not only do we have unrivalled competence and capacity in our field, but we also have exclusive access to an OJEU compliant framework that allows social housing providers to directly award PAS 2035 professional services. Removing the complexity and uncertainty of open tender, the Surefire framework is unique, easy to work with and offers a low-cost, best-value procurement solution for local authorities and social housing landlords. Established in 2013, the Surefire framework has procured over £150 mil. of high-quality retrofit services that have been delivered on funded projects (ECO, SHDF, LAD, HUG) across the UK. Services can be procured individually or bundled as a custom package based on your needs and the goals of your project.
