Stroma Certification's Retrofit Assessor Certification Scheme is a TrustMark approved scheme that works within the new PAS 2035 Framework, the specification for the energy retrofit of domestic buildings.

Upon completion of Retrofit Assessor training, candidates will be eligible to join this scheme enabling them to become certified to carry out and lodge Retrofit Assessment Reports. All Retrofit work will be carried out in-line with the new PAS 2035 framework.

Assessors will gather a variety of information including, but not limited to the identification of the installed building services, an appraisal of the dwelling’s heritage and an identification of any constraints imposed by the local planning authority.

What is the Retrofit Assessor Certification Scheme?

Stroma Certification’s Retrofit Assessor Scheme is a TrustMark approved scheme that provides certification for Assessors carrying out domestic retrofit work in-line with the PAS 2035 standard framework. It is the responsibility of the Assessor to collect data on aspects of the property relating to all retrofit work including the functionality and durability of buildings, energy efficiency and the environmental impact of buildings.

Retrofit Assessor role summary

The main role of the Retrofit Assessor will be to visit the property and prepare a report in-line with a Retrofit Coordinator's requirements. The Retrofit Coordinator will issue an instruction to the Assessor based on their initial risk assessment under one of the assessment paths A, B or C. These assessment paths determine the level and types of information the Assessor will be required to gather and include in their report. In most cases, a standard data set will be gathered and uploaded to the data warehouse, thereby completing the bulk of the retrofit assessment.

Stroma Certification is one of the only certification bodies to offer TrustMark membership for our DEA Certification scheme. You can add TrustMark for only £50+VAT.
