Property data API for landlords.

The Landlord Package gives you EPC ratings (current and potential), energy efficiency scores, floor area, council tax bands, flood risk, and rental market data: all via a single REST API. Use it to audit your portfolio for EPC compliance, assess BTL acquisitions, and pull rental comparables. Covers England and Wales.

The UK government's Minimum Energy Efficiency Standards (MEES) regulations are set to require all new and renewed tenancies to have a minimum EPC rating of C by 2028 (exact date subject to final legislation). Properties currently rated D or below will need to be upgraded before they can be legally let. The Homedata EPC API lets you check the current rating of a property in England and Wales with a lodged certificate, by UPRN.

Yes. The /epc-checker/{uprn}/ endpoint accepts any UPRN in England and Wales and, where a certificate has been lodged, returns the current EPC rating (A–G), numeric energy efficiency score (1–100), floor area, and construction age band. Call it in a loop for each property in your portfolio. At 1 token a property, a £50 top-up (5,000 tokens) checks 5,000 properties.

Yes: listing history covers asking prices, status changes and time to let. It is arranged per customer rather than sold self-serve, so it is set up with us rather than bought with tokens. Use it to benchmark your asking rent against comparable properties or track rental demand in your target postcodes.

The Landlord Package is pay as you go: 100 tokens = £1. EPC checker and property characteristics are 1 token each; council tax band is 3 tokens. Your first top-up is matched 100%: enough to build your integration and check your first properties. No subscription required to start.

Yes. Before any BTL acquisition you can pull: EPC rating and potential improvement headroom, flood risk band, council tax band, property type and bedrooms, listing event history (DOM, price reductions, prior instructions), and comparable sold prices, all from the UPRN. Everything you need to stress-test the yield calculation and flag hidden risks.

The UK government is legislating that all private rental properties must achieve a minimum EPC rating of C before they can be let. The current target is 2028 for new and renewed tenancies, with all existing tenancies to follow. Properties rated D or below will need energy efficiency improvements (loft insulation, cavity wall insulation, double glazing, or heat pump installation) before landlords can legally re-let them. Note: the exact dates are subject to final legislation. Always check the latest MEES guidance from the government.

Not all properties have a lodged EPC: particularly those that have never been sold or rented since 2008 (when EPC became mandatory for most transactions). The Homedata EPC endpoint will return a 404 if no certificate exists for the UPRN. You'll need a qualified energy assessor to carry out a new assessment. The endpoint also returns the lodgement date so you can flag certificates that are approaching expiry (EPCs are valid for 10 years).

Yes. The /risks/flood/?uprn= endpoint returns river, sea and surface water flood risk bands for any UPRN in England. Available to every account. This is important for mortgage lenders (some will require flood risk checks) and for assessing buildings insurance costs.

Yes. The property characteristics endpoint returns property type, number of bedrooms, and floor area: all key inputs for HMO licensing calculations. Council tax band data helps confirm the council billing category. EPC is also relevant for HMOs: each individual unit in a converted property may need its own certificate.

This is a developer API: it returns JSON data rather than a polished interface. If you want to use it without writing code, the easiest approach is to hire a developer to build a simple CSV-to-compliance-report script using our API. A single developer could audit your entire portfolio in an afternoon for under £50 in API costs.
