We've been working with Build UK, the Civil Engineering Contractors Association (CECA) and a number of contractors in the industry to develop one simple and unified set of pre-qualification questions. 

As a recognised assessment body we've included the new CAS in to our BuildingConfidence community questionnaire. For Buyers this means you can recognise CAS certification from any approved assessors and for Suppliers you benefit from completing just one audit and pre-qual per year for the entire industry. 

One simple supplier pre-qualification process, fit for all and recognised industry-wide. Learn more about our BuildingConfidence community.


As one of the recognised assessment bodies, we will continue to work towards our key goals of developing and embedding best practice in the construction industry. Allowing companies to be certified just once, by one of the recognised assessment bodies, is a welcome development.
