Energy Performance Certificates (EPCs) are unreliable and in desperate need of reform says Which
Consumer group Which? highlights inaccuracies in EPC assessments, such as missing features like solar panels, leading to misleading advice for homeowners. They call for improved assessor training and clearer guidance on energy efficiency improvements.
The Role and Importance of EPCs
Introduced in 2007, EPCs are intended to provide a standardised measure of a property’s energy efficiency, rated from A (most efficient) to G (least efficient). They are required when a property is built, sold, or rented, and they offer recommendations for improving energy performance. EPCs influence property values, rental eligibility, and access to government grants and green financial products.
Which?’s Investigation into EPC Accuracy
Which? conducted assessments for 12 homeowners across England, Wales, and Scotland, revealing widespread errors in EPCs. Issues included unmentioned solar panels and wood-burning stoves, as well as expensive recommendations that would take decades to pay off. Only one homeowner expressed satisfaction with their EPC. These inaccuracies can mislead homeowners and result in costly, ineffective energy efficiency improvements.
Calls for Reform
Which? advocates for several reforms to improve the reliability and usefulness of EPCs:
- Enhanced Assessor Training: Reviewing the training requirements for Domestic Energy Assessors (DEAs) to ensure they can accurately assess diverse property types.
- Improved Auditing: Implementing stricter auditing of EPCs to maintain high standards and accountability.
- Clearer Guidance: Redesigning EPCs to provide clearer, actionable advice for homeowners, including information on financial support for upgrades.
These reforms aim to make EPCs a more reliable tool for consumers looking to improve their home’s energy efficiency.
Government Response and Ongoing Consultations
The UK government has acknowledged the need for reform and is seeking views on the Energy Performance of Buildings (EPB) framework. The consultation covers areas such as clarifying regulations, updating EPC metrics, refining requirements, improving data management, and strengthening quality control. These efforts aim to enhance the applicability, quality, and data usage of energy certificates in domestic and non-domestic buildings.
Conclusion
EPCs play a crucial role in the UK’s efforts to improve energy efficiency and reduce carbon emissions. However, the findings by Which? highlight significant shortcomings in the current system. Implementing the proposed reforms is essential to ensure that EPCs provide accurate, actionable information, enabling homeowners to make informed decisions about energy efficiency improvements.
