PropEco has launched an EPC Audit tool designed to identify and correct errors in Energy Performance Certificates (EPCs)in a move aimed at safeguarding property values and reducing risks for lenders, buyers and landlords.
EPCs, which measure the energy efficiency of homes, have become increasingly influential in buying decisions, mortgage pricing and property valuations as the UK accelerates its drive towards net zero.
Properties with higher ratings are often more valuable: some studies show that A-rated homes can attract price premiums of 12 per cent or more.
SIGNIFICANT ERRORS
Yet more than half of EPCs contain at least one significant error, according to industry research.
PropEco said these inaccuracies risk overstating or understating running costs, retrofit requirements and, crucially, the true value of a property.
Errors can also result in properties being reclassified into lower EPC bands, potentially cutting values, jeopardising sales or pushing landlords out of compliance with minimum efficiency standards.
AVOID MISTAKES

Chris Hardman, director at PropEco, said: “Incorrect EPC data isn’t just a clerical issue; it’s a financial liability.
“A downgraded EPC rating can reduce a property’s value overnight, derail transactions or expose lenders to higher default risk.
“Our EPC Audit tool provides clarity by flagging inconsistencies and helping stakeholders avoid costly mistakes.”
ENHANCED EPC DATASET
The tool is built on PropEco’s Enhanced EPC dataset and applies hundreds of automated checks to assess the accuracy of certificates.
It can be used via API integration, bulk data downloads for portfolio analysis, or through the company’s online Data Explorer platform.
PropEco argues that by providing a clearer picture of energy efficiency, the EPC Audit will help lenders better manage exposure, protect consumers from unexpected retrofit costs and give valuers and surveyors more reliable data to underpin transactions.
