Review needed for Energy Performance Certificate (EPC) rating system assessments
The UK government, in collaboration with several organisations, has proposed measures to enhance energy efficiency assessments and schemes, aiming to meet the Net Zero 2050 goals. One of the key initiatives is the launch of the Energy Efficiency Scheme (EES), supporting energy efficiency measures for various organisations.
However, concerns have been raised about the effectiveness of Energy Performance Certificates (EPCs) in accurately assessing a home's energy efficiency. The UK consumer watchdog, Which?, claims that EPCs are hindering the country's push for more energy-efficient homes.
According to a recent report, only 29% of the UK population have seen the section with advice on how to improve their EPC rating, and only 36% know or have a sense of their EPC rating. The report also states that for EPCs to be effective, they need to have relevant, accessible, and accurate information and advice.
Which? suggests several improvements to EPCs. Firstly, the software models used to generate EPC ratings should include location data and be regularly updated with data about new heating technologies and models. Secondly, introducing more than one primary metric in EPCs could support consumers' understanding of energy use in properties. The suggested choice of metrics could include the property's energy use, cost, heating system, and environmental impact.
Moreover, the report recommends improving the auditing of EPCs and making it easier for consumers to review assessors and access a complaint process. There is also a suggested overhaul of the training requirements for Domestic Energy Assessors (DEAs).
Experts at Which? recommend that EPCs should include more information to support consumers in transitioning from fossil fuel heating to new low-carbon heating systems. The advice in an EPC should be relevant to the type of property, according to Which?.
EPCs, introduced in 2007, have not kept pace with the necessary changes, according to the report. To address this, it is suggested that every property that is sold or let should have an EPC that is less than five years old.
In conclusion, the UK government is approaching the legal requirement to reach Net Zero in 2050, and EPCs are seen as a crucial tool in helping households manage fluctuating energy bills. However, to fulfil this role effectively, EPCs need to be improved to provide clear, relevant, and accurate information to consumers.
