An EPC rates a home's energy efficiency from A to G, produced by an accredited domestic energy assessor, with recommendations for improvement. It drives letting compliance under MEES and underpins retrofit planning.
Providers need a current EPC for every let home, and portfolio-wide ratings determine exposure to tightening minimum standards and retrofit funding opportunities. The data matters as much as the certificate.
EPCs are required under the Energy Performance of Buildings Regulations 2012, with the Minimum Energy Efficiency Standard regulations making it unlawful to let domestic property below EPC E in England and Wales (subject to exemptions).
Regulatory frameworks differ across the UK — see the city pages below for Scotland, Wales and Northern Ireland specifics.
On construction, sale or a new let — and once the existing certificate passes ten years old you'll need a new one before the next of those events. Kaarr flags expiries well ahead.
MEES sets the minimum rating to let (currently E in England and Wales, private sector). Standards are tightening across tenures, so most providers now manage EPC data portfolio-wide.
Yes — ratings, recommendations and archetypes across the portfolio are the starting dataset for retrofit programmes and funding bids, and Kaarr keeps it queryable.
An EPC is valid for ten years and required whenever a home is built, sold or let. Minimum energy efficiency standards (MEES) currently require EPC E or better to let in England and Wales, with proposals to raise the bar — making portfolio EPC data a live planning tool, not a filing exercise.
