What's included
EPC Rating →
Current and potential EPC rating (A–G) with numeric efficiency score (1–100) and environmental impact rating.

Total floor area in square metres as recorded on the EPC certificate. Useful for price-per-sqm calculations.
Construction Age →
Construction age band from the EPC record (e.g. "1930-1949", "2020-2029"). Filter and segment by building era.
Certificate Date →
Last EPC lodgement date — flag expiring certificates (valid 10 years) before they become a compliance gap.

Frequently asked questions
What EPC data is covered?
The dataset includes current EPC band (A–G), energy efficiency score (1–100), potential EPC band, potential efficiency score, environmental impact rating, total floor area (m²), construction age band, and lodgement date. Where multiple certificates exist, the most recent is returned.
Where does the data come from?
EPC data is sourced from the MHCLG EPC Register — the official government database for England and Wales. Homedata syncs continuously so new certificates appear within 24–48 hours of lodgement.
How often is the data updated?
The MHCLG register is updated as new EPC certificates are lodged. Homedata ingests updates on a continuous basis — new certificates typically appear in the API within 24–48 hours.
What do EPC bands mean?
Bands run from A (most efficient, score 92–100) to G (least efficient, score 1–20). Band C (score 69–80) is the target for government retrofit schemes. Landlords must achieve at least band E under current MEES rules, with band C proposed for new tenancies from 2028.
How much does the EPC API cost?
The EPC Checker endpoint (GET /api/epc-checker/{uprn}/) is completely free — no API key required. Full property lookups including EPC data are available on paid plans from £49/month, or via the free tier (100 calls/month, no card needed).
