The retrofit coordinator is the person who oversees an energy-efficiency project on your home from start to finish. Where the assessor surveys the property, the coordinator uses that information to plan the work, manage quality and sign it off. For any government-backed scheme — including ECO4 and other grants — having a qualified coordinator in place is a requirement, so understanding the role tells you a lot about whether a job is being done properly.

What a retrofit coordinator does

The role was created by PAS 2035, the British standard for domestic retrofit, to bring a single accountable person to projects that used to be left to individual installers. The coordinator:

  • Plans the whole retrofit – deciding which measures suit your home, in what order, and how they work together safely.
  • Manages risk and quality – making sure ventilation, moisture and heating are considered together, not measure by measure.
  • Coordinates everyone involved – assessor, designer, installers and evaluator — and keeps you informed as the client.
  • Lodges the project with the TrustMark Data Warehouse, which is what allows the work to qualify for funding.

Why it matters to you

The coordinator is meant to be independent of the installers, so you get impartial technical advice rather than a sales pitch for particular products.
That independence is central to the quality protections built into ECO4 and similar schemes, which are administered by Ofgem under government policy. If measures fail or cause problems later, the coordinated, documented trail is also what makes it easier to put things right.

Before work starts, it is fair to ask who your retrofit coordinator is and to confirm the firm is TrustMark-registered. For more on the schemes a coordinator works within, see our energy and water guidance and the support available through renewable energy grants.
