  • Undertake U-value calculations, thermal bridging analysis, and condensation risk assessments to support robust design outputs.
  • Liaise with the Retrofit Coordinator to finalise Medium-Term Plans (MTP) and ensure designs are deliverable, practical, and aligned with programme budgets.
  • Prepare and issue design risk assessments and relevant health and safety information to comply with CDM 2015 and PAS2035 design responsibilities.
  • Participate in design reviews, toolbox talks, and site inspections where required to ensure design intent is maintained through to delivery.
  • Maintain knowledge of technical standards, DESNZ guidance, and updates in retrofit best practice to continuously improve design quality.

About You

  • Competent in Microsoft Excel, Word, PDF, Revit/CAD and good level of IT knowledge/adaptability to using software’s and project management platforms such as AirTable.
  • Professional background in building design, architecture, building surveying, or building services engineering with direct experience of domestic retrofit projects.
  • Proven understanding of PAS2035:2023 requirements and the Whole House Retrofit approach.
  • Strong technical knowledge of fabric-first measures, insulation systems, ventilation design, thermal bridging, and moisture management.
