Heat in Buildings strategy - domestic EPC reform consultation: analysis summary report

Executive Summary

In summer 2021, we consulted on proposals to amend Energy Performance Certificates (EPC). We set out several proposals which were intended to enable EPCs to support planned regulations, as set out in our 2021 Heat in Buildings Strategy (HiBS).

These were principally to introduce a new metric of energy efficiency, based on the amount of energy used by a dwelling. We proposed to call the new metric an Energy Use Rating. This new metric would sit alongside the current Energy Efficiency Rating, which we would rename to an Energy Cost Rating reflect that it is based on running cost. We also proposed to retain and rename the Environmental Impact Rating as a Carbon Emissions Rating. We proposed changes to the way that information is presented on the EPC.

Current Metrics

Energy Efficiency Rating (£): Based on running cost (£ per m²)

Environmental Impact Rating: Based on emissions (kg CO2e per m²)

Proposed Metrics

Energy Cost Rating: Based on running cost (£ per m²⁾

Carbon Emissions Rating: Based on emissions (kg CO2e per m²)

Energy Use Rating: Based on delivered energy (kWh per m²)

Respondents broadly agreed with our proposals. There was strong support for the introduction of a new metric to report energy efficiency based on energy use. Some respondents suggested a metric based on demand, rather than use, would be more appropriate. Respondents supported our proposals to rename the existing metrics.

However, respondents stressed the need for EPCs to provide clear, simple, and useful information to users. Respondents also noted the need for issues to be addressed in the underlying methodologies. We will take these concerns into account as we develop detailed proposals.

We will set out an updated policy proposal in further consultation planned for our proposed regulatory framework for heat and energy efficiency, outlined in the HiBS. This consultation is due to be published within the next year.
