Quidos is a TrustMark approved Retrofit Assessor scheme, in line with the PAS 2035. This is the specification for the energy retrofit of domestic buildings. Becoming a retrofit assessor and member of a scheme will mean you are fully qualified to work on domestic retrofit projects.
A quality mark has been produced by Trustmark and Retrofit assessors require this mark of approval to show they are accredited with an approved scheme and able to carry out their part of a retrofit project. In addition, the quality mark can be used by assessors to show that their skills, practices and standards are of the highest quality.
