PAS 2038 Retrofit Assessments
Whole-building retrofit plans to improve energy performance, meet compliance targets, and support long-term decarbonisation.
If you’re planning to upgrade a commercial property, improve EPC ratings, or develop a net zero strategy, a PAS 2038 retrofit assessment provides a structured, risk-managed approach to building improvements.
What is a PAS 2038 Retrofit Assessment?
-
A PAS 2038 retrofit assessment is a comprehensive evaluation of a non-domestic building, designed to identify the most effective way to improve energy performance.
-
Unlike a standard EPC or energy audit, it takes a whole-building approach, considering how fabric, services, and occupancy interact. The goal is to develop a coordinated retrofit strategy that avoids unintended consequences and delivers measurable improvements.
When do you need a PAS 2038 assessment?
You may benefit from a PAS 2038 retrofit assessment if you are:
-
Planning to improve an EPC rating for MEES compliance
-
Developing a decarbonisation or net zero strategy
-
Applying for funding or grants requiring PAS 2038 alignment
-
Managing a portfolio of commercial properties
-
Upgrading older or complex buildings
-
Looking for a structured, phased improvement plan
What's included?
A typical PAS 2038 retrofit assessment includes:
-
Detailed site survey and data collection
-
Assessment of building fabric and construction
-
Review of building services (heating, cooling, ventilation, lighting)
-
Analysis of current energy performance
-
Identification of improvement measures
-
Evaluation of interactions between measures
-
Risk assessment (e.g. moisture, overheating, unintended consequences)
-
Phased retrofit strategy (short, medium, and long term)
How is this different from an EPC or energy audit?
While there is some overlap, each service serves a different purpose:
EPC (Energy Performance Certificate)
Provides a compliance rating and standardised recommendations.
Energy Audit
Focuses on operational energy use and cost-saving opportunities.
PAS 2038 Retrofit Assessment
Delivers a whole-building improvement plan, designed for safe, effective and staged upgrades.
How this fits with your existing EPC or audit
A PAS 2038 assessment is often the next step after an EPC or energy audit.
-
Already have an EPC? → Use PAS 2038 to plan how to improve the rating
-
Completed an energy audit? → Use PAS 2038 to structure capital upgrades
This ensures improvements are coordinated, compliant, and aligned with long-term performance goals.
