UK EPC Intelligence — Energy Performance & Upgrade Costs

Query the official UK Government EPC Register by postcode and get structured energy performance data per property — including stranded asset risk, estimated upgrade costs, and improvement recommendations.

Uses the official get-energy-performance-data.communities.gov.uk API. No scraping, no ToS risk, no third-party data resellers.

Why This Exists — The 2028 Deadline

From 2028, all buy-to-let properties in England and Wales must hold an EPC rating of C or above to be legally rented. Every landlord with a D, E, F, or G rated property faces a decision: upgrade, sell, or face fines.

This Actor answers the core question: which properties are at risk, what will it cost to fix them, and what improvements are recommended?

---

Who It's For

• Buy-to-let landlords — audit a portfolio or a target street for compliance risk before the 2028 deadline
• Estate agents and valuers — identify stranded assets in a target area for investor and developer clients
• Retrofit assessors and energy consultants — find properties that need upgrade work in a given postcode
• Property investors — screen acquisitions for hidden compliance cost before purchase
• Developers — identify the energy profile of a target area before committing to a site

Data Source

All data comes directly from the Ministry of Housing, Communities and Local Government EPC Register — the same database used by assessors, mortgage lenders, and the government's own compliance enforcement. Over 24 million certificates covering England and Wales.

This Actor queries the official API directly. It does not scrape, cache, or redistribute the underlying data — each run fetches live results from the primary source.

Combine With

• HMLR Price Paid — join on UPRN to get sale price + EPC rating per property, calculate price per sqm, identify stranded assets in a sales pipeline
• Liveability and area scoring — layer EPC data over crime, schools, and transport for investment decisions
• Apify datasets — export to Google Sheets, Airtable, or webhook for portfolio tracking

---

Notes

• EPC certificates expire after 10 years. Properties with no current certificate will not appear in results.
• Coverage is strongest for properties that have been sold or let since 2008 (when EPC became mandatory).
• Flats in converted houses have lower coverage than purpose-built flats and houses — approximately 85% vs 100% for houses in tested postcodes.
• The Actor returns the most recent certificate per property. Historic certificates are not returned.
