Competency Scheme

The BBA operates a Scheme for assessing and monitoring U-Value and condensation risk calculation competency. The Scheme seeks to promote and assist accurate, objective and consistent calculation of U-Values and condensation risk within buildings.

Registration under the Scheme provides reassurance to any specifier or user that the services or data being provided are supplied by an individual or company that has been subject to a rigorous independent assessment process. They can therefore be assured that this output is representative and reliable.

The content of the Scheme was devised in association with the Thermal Insulation Manufacturers and Suppliers Association (TIMSA), who continue to participate in maintaining its validity with on-going development. However, it is also open to individuals and companies who are not members of TIMSA. For further details please request our brochure by emailing clientservices@bba.star.co.uk.

The Scheme is operated in four separate stages:-

  • an initial screening
  • an office inspection
  • validation and conclusions (followed by the issue of a Certificate to the company that employs the Competent Person(s))
  • ongoing surveillance

The process is described in detail in the Scheme Document. For information on the specific data sources please click here.

Scheme members will be required to demonstrate appropriate technical competency and in-house procedural controls to ensure that their declared calculations are reasonable. They are then permitted to identify calculations covered by the Scheme by means of the dedicated BBA Scheme Logo. The Competent Person is identified within the logo by the use of a unique number for each individual.
