The background of Retrofit Coordinator Service

What is a Retrofit Coordinator?
A Retrofit Coordinator is responsible for overseeing domestic retrofit projects, from inception to completion, in order to comply with PAS 2035. This is to support clients and the general public.

What is the difference between a Retrofit Coordinator and a Retrofit Assessor?
A Retrofit Assessor is trained to carry out a retrofit assessment of dwelling in accordance to PAS 2035. This assessment includes a detailed floor plan, a condition report, and an occupancy assessment. The data collected is then used by the Retrofit Coordinator to devise an improvement plan.

What do you, as an Installer, need to do?
Installers who carry out work under PAS 2030:2019 require PAS 2035:2019 location specific design which for both Path A or B and can be provided by a Retrofit Coordinator who must lodge the required Retrofit Project details in the Data Warehouse. Therefore, the Retrofit Coordinator must hold or be working towards a Level 5 NVQ in Retrofit Coordination and Risk Management and be Certified by a TrustMark RC Scheme Provider such as The IAA CS.
