The BBA operates a scheme for assessing and monitoring the competency of U-value and condensation risk calculations. The content was devised in association with TIMSA (the Thermal Insulation Manufacturers and Suppliers Association), who continue to participate in maintaining its validity with continual development. However, the scheme is open to non-TIMSA members as well, and to anyone seeking reassurance that the calculations being provided are supplied by an individual or company that has been subject to a rigorous and ongoing independent assessment process.
The scheme is also included in the RdSAP conventions document (the version of SAP dedicated to existing dwellings as a recognised calculation competency scheme).
The assessment process for the BBA/TIMSA U-Values and condensation risk competency scheme consists of four simple steps:
Each Competent Person is given a unique number and this is used as an identifier of calculations covered by the scheme. A certificate is provided at the successful completion of this process, and these certificates are also published on the BBA website. Competency can, therefore, be demonstrated.
The scheme does not include a course or training; it is an assessment of competence in relation to U-values via the combined method (not numerical modelling). Therefore we advise that assessment under the scheme should be undertaken once you consider yourself ready, as we don’t have any pre-requisites.
