Important Notes — 2025/26 Rates & Caveats
PAS 2035:2019 requires a Retrofit Coordinator to oversee all ECO4 and GBIS projects. The coordinator is responsible for the whole-house retrofit assessment, design, specification oversight, monitoring and handover. The PAS 2035 framework replaced PAS 2030 (installer-only focus) to ensure a systems approach. Retrofit Coordinator accreditation is held through a UKAS-accredited scheme (TrustMark). Fees in 2025/26 typically range from £200–£600 per property depending on project complexity and number of measures. ECO4 project coordinators often work to fixed fees agreed with the energy supplier or installer.
Frequently Asked Questions
What is a PAS 2035 Retrofit Coordinator?
A PAS 2035 Retrofit Coordinator (RC) is a qualified professional responsible for overseeing the whole-house approach to energy efficiency retrofit. The RC manages the retrofit assessment, designs the improvement plan (Medium Term Improvement Plan), monitors the quality of installation work and produces handover documentation for the homeowner. The role is mandatory for ECO4 and GBIS projects. RCs must hold a relevant qualification (typically ABBE Level 5 Diploma in Domestic Retrofit Coordination) and be registered with TrustMark.
How much does a Retrofit Coordinator charge for an ECO4 project?
PAS 2035 Retrofit Coordinator fees for ECO4 projects in 2025/26 typically range from £200–£600 per property. Simple single-measure projects (e.g. loft insulation only) command lower fees; complex multi-measure projects with heat pumps, wall insulation and ventilation require significantly more time. Many large ECO4 supply chains negotiate fixed RC fees with coordinators, often at £250–£400 per property for volume work. Independent coordinators working directly with homeowners on private retrofit projects can charge £400–£800+ per property.
What is the difference between ECO4 and the Great British Insulation Scheme (GBIS)?
ECO4 (Energy Company Obligation 4) targets fuel-poor and low-income households, requiring comprehensive whole-house retrofit under PAS 2035. GBIS (Great British Insulation Scheme, launched 2023) targets a broader range of households in EPC bands D–G and council tax bands A–D, with a focus on a single insulation measure per property. GBIS projects with a heat pump or multiple measures still require a Retrofit Coordinator under PAS 2035. Both schemes run until March 2026. A successor scheme is expected from April 2026.
