PropEco, the property data and analytics firm, has announced the roll-out of its EPC Audit tool – a unique product designed to identify errors within Energy Performance Certificates (EPCs). The solution aims to provide more reliable insights into home efficiency, protect asset values and support the country’s drive towards net zero.
As sustainability targets shape the UK housing market, EPC scores are becoming central to decision-making. They are now influencing mortgages, valuations and buyer interest more than ever before. Evidence highlights the financial impact, with research finding that A-rated homes can attract premiums exceeding 12% compared with lower-rated equivalents.
However, analysis indicates that over 50% of EPCs contain at least one major inaccuracy. This compromises the data relied upon in countless property assessments each month, often misrepresenting true running costs, retrofit pathways and liveability. Crucially, it can also distort market valuations, with many homes being reclassified into lower EPC bands once errors are corrected.
“Incorrect EPC data isn’t just a clerical error; it’s a financial liability waiting to happen,” said Chris Hardman, Director at PropEco. “A downgraded EPC rating can slash property value overnight, derail sales, or push landlords into non-compliance with minimum energy efficiency standards, increasing mortgage default risk. PropEco’s EPC Audit tool is designed to flag the many identifiable issues within EPCs, helping stakeholders spot hidden opportunities as well as avoid costly mistakes.”
Built on PropEco’s
Enhanced EPC dataset, EPC Audit applies hundreds of automated checks to flag inconsistencies and errors that could impact the utility and value of a property. This empowers surveyors, valuers, lenders, and buyers to make better-informed decisions and mitigate the risk of unexpected devaluations or costly, unforeseen retrofit obligations.
“Lenders increasingly tie mortgage rates to EPC bands A-C but relying on flawed EPC data creates a huge risk.” Hardman added. “PropEco’s EPC Audit tool is designed to ensure that assessments reflect reality, protecting all stakeholders in the property transaction and future-proofing lending books.”
EPC Audit is available immediately via PropEco’s platform, which offers flexible access through an API for system integration, bulk data download for large-scale portfolio analysis, or a browser-based
Data Explorer.
