Chartered Building Companies

Organisations chartered with CIOB are independently assessed and regularly audited. They can demonstrate that they:

  • Are competently and professionally run
  • Operate to high business and ethical standards
  • Are committed to developing a fully qualified workforce
  • Have a significant number of directors that are already Chartered, either with CIOB or other built environment organisations


Board directors of CBCs lead by example: At least half are Chartered with a built environment organisation, and a minimum of 25% of the board have full CIOB membership (MCIOB or FCIOB). Those who have achieved MCIOB or similar have a duty to maintain rigorous standards in all their activities, and this will be reflected in the organisation’s operations as a whole.

Chartered organisations are allowed to use the CBC logo and to add their profile to a prestigious public directory.

The CBC scheme has been running for more than 20 years. It’s administered and promoted by CIOB and has the backing of our strong international brand.


What kind of building company can become Chartered? 

Any organisation that is involved with building can apply to become a CBC. Contractors, subcontractors, developers, clients, and even councils are eligible. There are no geographical limitations: applications are welcome from building-related organisations anywhere in the world.

Chartered Building Companies can be any size, from two or three person operations to multinationals. Branches of larger companies can also apply for CBC status, with the approval of their parent company or main board.

The key requirements are that at least half of board directors are Chartered and at least 25% Members or Fellows of CIOB. The company must have been trading for at least two years. Contact us for further advice.
