What is a Retrofit Coordinator and what do they do?
A Retrofit Coordinator oversees retrofit projects on existing homes in line with PAS 2035. They manage the whole process, working alongside qualified specialists responsible for each stage of the project. The Retrofit Coordinator is a mandatory role for all retrofit projects as outlined in PAS2035.
Coordinators guide the project from the initial assessment through to evaluation and beyond, protecting the interests of the client, the occupants and the public. They work with the client to agree what the project should achieve, then review the assessment findings and coordinate a suitable design.
A key part of the role is taking a whole-house approach by understanding how proposed improvements will work together and managing the technical and process risks associated with domestic retrofit projects.
The Retrofit Coordinator plays a pivotal and overarching role in the retrofit process.
