Retrofit Coordination is the process of managing and aligning all aspects of energy efficiency upgrades or refurbishment works within a building, ensuring everything is delivered safely, on time, and in compliance with industry standards.
A Retrofit Coordinator acts as the central figure who brings together installers, designers, assessors, and clients, ensuring that each stage of the retrofit project is planned, risk-assessed, quality-assured, and documented correctly. Their role is essential to delivering successful retrofits under standards such as PAS 2035.
Why It Matters:
Ensures compliance with national retrofit standards (e.g., PAS 2035)
Minimises performance gaps and project risks
Improves energy efficiency, sustainability, and occupant comfort
Coordinates health & safety, design, and installation seamlessly
Turning Assessment into action - A Retrofit Design is the detailed plan that will outline how the energy efficiency improvements will be installed in a building, following the thorough assessment of its current condition. It is a key stage in the PAS 2035 retrofit process and ensures that any upgrades are safe, effective, and tailored to the specific needs of the property. At its core, the retrofit design transforms the recommendations from the Retrofit Assessment into a workable, site-specific design that considers the building’s structure, occupancy, ventilation, insulation, heating systems, and potential risks such as damp or overheating.
Key Elements of a Retrofit Design:
Whole-Building Approach: Considering how all elements of the property will interact to avoid unintended consequences, like poor ventilation or condensation.
Improvement Measures: Specifying the materials, systems, and techniques to be used, such as insulation types, heating upgrades, or renewable energy technologies.
Moisture Risk & Ventilation Strategy: Ensuring that improvements do not compromise indoor air quality or structural integrity.
Compliance with PAS 2035: The design meeting the standards set out in the UK’s quality framework for domestic retrofit projects.
Why It Matters:
A high-quality retrofit design ensures that energy upgrades are:
Safe and appropriate for the building’s age, type, and condition
Aligned with the goals of reducing carbon emissions and fuel bills
Delivered in the correct sequence, minimising risks and maximising efficiency
Fully compliant with industry regulations and TrustMark requirements
Retrofit Assessment is the first essential step in the retrofit process. It involves a detailed evaluation of a property to understand its current energy performance, structure, and suitability for improvement.
A qualified Retrofit Assessor visits the home or building to collect data on everything from insulation and ventilation to heating systems and occupancy patterns. This information forms the foundation for creating a safe, efficient, and tailored retrofit plan in line with standards like PAS 2035.
What Does It Include?
RdSAP Energy Assessment – current energy rating and usage
Condition Survey – structural and maintenance checks
Occupancy Assessment – how the property is used day-to-day
Why It’s Important:
Identifies risks or limitations before any work begins
Ensures the right measures are proposed for maximum benefit
Helps avoid issues like damp, overheating, or poor ventilation
Supports a whole-house, long-term improvement strategy
