Full job description
ARPG Eco delivers whole-house retrofit, renewables and M&E projects across the Northwest and Wales under PAS 2035/2030 (ECO4/GBIS, LA programmes). We’re expanding and hiring a Retrofit Coordinator to own end-to-end coordination—from survey and modelling through design sign-off, installation oversight and handover.

• Produce solar PV designs (array layout, stringing, module/inverter choice, yield, DNO G98/G99 inputs).
• Produce ASHP designs (sizing from heat loss, flow temperatures, emitter checks, cylinder, siting/noise).
• Assess and specify ventilation upgrades to Part F; coordinate compliance to Part L and PAS.
• Compile Retrofit Plans, Installation Plans and Handover packs; TrustMark lodgements.
• Coordinate designers/assessors/installers; complete interim/post-install QA and reporting.

Requirements (essential)

• Level 5 Diploma in Retrofit Coordination & Risk Management (or near-completion).
• Solid building knowledge (construction methods, building physics, fabric/MEP interfaces).
• Proven experience with heat-loss calcs, retrofit modelling, solar PV and ASHP design.
• Working knowledge of PAS 2035, Part L/F, moisture risk principles (BS 5250), TrustMark.
