The Scottish Government has introduced reforms to Energy Performance Certificates (EPCs) aimed at improving energy efficiency and supporting net zero targets. These changes include a new rating system, updated technical infrastructure, and enhanced quality assurance measures. The reforms apply uniformly across Scotland, including its island communities.

Island-specific challenges such as limited assessor availability, higher travel costs, and unique housing stock were considered during the assessment. While these factors may influence the cost and logistics of EPC delivery, the regulations include mitigations—such as grace periods and legal defences for non-compliance due to assessor unavailability—that help ensure fair treatment.

The revised EPC system introduces three distinct ratings: Heat Retention, Heating System, and Energy Cost. This approach benefits buildings off the gas grid, common in island areas, by separating fuel cost from insulation performance. The reforms also aim to make EPCs more understandable and useful for property owners and tenants seeking to improve energy efficiency.
