The next government has been urged to overhaul Energy Performance Certificates (EPCs) following an investigation by consumer group Which? that revealed inaccuracies and impractical recommendations.
EPCs, introduced in 2007, aim to help buyers and renters compare properties’ energy efficiency.
However, findings indicate that EPC assessments often contain errors and unhelpful advice, potentially affecting homeowners’ ability to improve their homes or qualify for green financial products.
In a study involving 12 homeowners across England, Wales and Scotland, most participants reported inaccuracies in their EPCs.
Only one homeowner was very satisfied, while eight reported errors in descriptions of their homes’ key features.
Issues ranged from unrecorded solar panels to overlooked draught proofing needs.
Rocio Concha, Which? Director of Policy and Advocacy, said: “With millions of families worried about high energy bills and the UK facing a big challenge to transition to low carbon heating, EPCs could be a helpful tool for consumers looking to save money and improve their home’s efficiency in the future.
“However, our research shows they are in desperate need of reform – with current certificates often inaccurate and only suggesting costly improvements with long pay back periods.
“The next government must make EPCs a more reliable and useful tool for householders.”
