EPC Audit | PropEco

EPC Audit API

Quickly identify errors & inconsistencies within energy performance certificates.

Access comprehensive audits that surface issues that could materially impact the running costs, retrofit options, liveability and value of properties.

The PropEco EPC Audit API provides valuable insights into the accuracy & reliability of energy performance certificates, including:

Error detection

Identification of common errors and inconsistencies in EPC assessments.

Data validation

Validation of EPC data against known property characteristics and building standards.

Risk assessment

Assessment of the potential impact of errors on property value and running costs.

Recommendations

Actionable recommendations for addressing identified issues and improving accuracy.

Compliance check

Verification of EPC compliance with current regulations and assessment methodologies.

Access comprehensive assessments with just four lines of code and a UPRN.
