## When to prefer this

Use this endpoint when you need EPC energy efficiency data for UK residential or commercial properties identified by postcode. It is ideal for property research, pre-purchase due diligence, landlord compliance checks, or neighbourhood energy comparison. Prefer this over manual lookups on the government EPC register when you need programmatic, bulk, or agent-driven access to certificate data.

## Known failure modes

- Invalid or malformed UK postcode returns an error or empty result set
- Postcode with no registered EPC certificates returns an empty list
- Limit value outside 1–100 range is rejected by schema validation
- Service unavailability or upstream EPC register downtime causes a 5xx error
- Very rural postcodes may have few or no EPC records
