PAS 2038 Compliance Support for Non-Domestic Retrofit

Get expert PAS 2038 compliance support for organisations, property owners, facilities managers and contractors improving commercial, public and other non-domestic buildings — from initial assessment through documentation and audit preparation, with a whole-building approach.

The basics

What Is PAS 2038?

PAS 2038 is the UK specification for retrofitting non-domestic buildings to improve energy efficiency. Rather than considering improvements in isolation, it encourages a whole-building approach — reviewing how proposed measures interact with:

  • Building fabric
  • Building services
  • Occupants
  • Interaction between measures
  • Existing conditions
  • Whole-building performance
Non-domestic only. PAS 2038 is specifically for non-domestic buildings. Domestic retrofit (houses and other dwellings) is covered by a different framework — PAS 2035. Knowing which applies at the start prevents confusion later.

Why it matters

Why PAS 2038 Matters for Non-Domestic Retrofit

Energy-efficiency retrofit can involve significant investment, and poorly coordinated improvements may not work together as expected. PAS 2038 encourages a structured, coordinated approach that helps identify suitable measures while considering their impact on the wider building — across elements such as:

  • Building fabric
  • Insulation
  • Heating
  • Ventilation
  • Lighting
  • Controls & other services

The objective isn’t simply to install individual measures — it’s to consider how improvements contribute to the overall performance and operation of the building.
