Energy Performance Certificates (EPCs) play a vital role in ensuring energy efficiency and compliance for residential properties across the UK. However, when it comes to multi-occupancy buildings and Houses in Multiple Occupation (HMOs), the EPC assessment process can be particularly challenging due to their unique structures and occupancy patterns.

If you’re a landlord, property manager, or investor dealing with HMOs or multi-occupancy properties in London, understanding these challenges can help you better prepare for accurate EPC assessments and improve energy efficiency.

What Are Multi-Occupancy Buildings and HMOs?

  • Multi-Occupancy Buildings: These are buildings divided into multiple self-contained flats or apartments, each housing separate households.

  • Houses in Multiple Occupation (HMOs): Properties rented to three or more tenants forming more than one household, typically sharing facilities like kitchens and bathrooms.

Both types require specialized approaches for EPC assessment due to their complexity.

Key Challenges in EPC Assessment for Multi-Occupancy Buildings and HMOs

1. Diverse Energy Usage Patterns

Individual units or tenants have different energy consumption behaviors, heating requirements, and schedules. This variability complicates energy modelling and affects the overall EPC score.

2. Shared Heating and Hot Water Systems

Many HMOs use centralized heating or hot water systems. Assessing these shared systems and allocating their energy use fairly to each unit is complex and can impact the EPC rating.

3. Variability in Building Fabric and Insulation

Multi-occupancy buildings often have varied construction periods or renovations, leading to inconsistent insulation and thermal performance across different flats.

4. Access and Metering Issues

Separate or shared meters and limited access to all units or communal areas may hinder comprehensive inspections, resulting in incomplete data for accurate EPCs.

5. Inclusion of Communal Areas

Common spaces like hallways and staircases consume energy but may be overlooked or inconsistently evaluated during assessments.
