Energy Performance Certificates (EPCs) are a legal requirement for most buildings when constructed, sold, or rented in the UK. But what about temporary and modular buildings—do these structures need EPCs? And how do the rules apply?

This article explains the EPC compliance landscape for temporary and modular buildings, helping property owners, developers, and managers understand their responsibilities and ensure energy efficiency standards are met.

What Are Temporary and Modular Buildings?

  • Temporary Buildings: Structures erected for short-term use, such as site offices, event spaces, or emergency accommodation.

  • Modular Buildings: Factory-built sections transported and assembled on-site, used for schools, offices, healthcare, or housing. They can be permanent or relocatable.

Both types offer flexibility but raise unique questions regarding EPC compliance.

EPC Requirements for Temporary Buildings

When Is an EPC Required?

Under current UK regulations, temporary buildings with a planned use of less than two years are usually exempt from EPC requirements. However, if the building is in use beyond this timeframe or sold/rented, an EPC may be necessary.

Key Considerations

  • Document intended use duration clearly to claim exemption.

  • Keep up-to-date records to demonstrate compliance during inspections.

  • Be aware that local authorities may have specific requirements.

EPC Compliance for Modular Buildings

Permanent Modular Buildings

If modular buildings are intended for permanent use, they must comply with EPC regulations like any traditional construction. This includes providing an EPC on sale or lease.

Relocatable Modular Buildings

For modular units designed to be moved frequently, EPC requirements depend on their use duration and occupancy. Long-term use generally triggers EPC obligations.

Challenges in EPC Assessment for Modular and Temporary Structures

  • Diverse Construction Methods: Factory-built components may differ in thermal performance compared to traditional builds, affecting EPC calculations.

  • Site-Specific Factors: Assembly methods, foundation types, and connections can influence energy efficiency.

  • Limited Historical Data: New building methods may lack comparable benchmarks for EPC modeling.
