Landlord portfolios
MEES requires non-domestic rented properties to hit E or better, with C by 2030 in the pipeline. Stack the EPC widget on every property in the portfolio dashboard to spot non-compliant units at a glance.

Configuration
All attributes go on the <div>.
| Attribute | Required | Notes |
|---|---|---|
| data-uprn | Required | 12-digit UPRN. EPC lookup needs the exact property identifier. |
| data-theme | Optional | light (default) or dark. |
| data-no-branding | Optional · paid tier | Hide the "Powered by Homedata" footer. |
Programmatic API
HomedataEPC.render({
container: '#epc-result',
uprn: '100023336956',
key: 'wt_your_public_key_here',
theme: 'dark',
});Pair it with the Address Widget
The cleanest UX is to capture the UPRN with the address autocomplete widget, then pass it to the EPC widget. One pasted form, two embed snippets, three calls — the customer never types a UPRN by hand.
Where the EPC widget belongs
EPC rating sits next to price on every property buyer's checklist. Surfacing it on the listing — with the official A–G colour palette — turns a regulatory data point into a recognisable trust signal.
Estate agents and portals
UK buyers expect EPC on every listing — Rightmove and Zoopla normalised it. The widget renders it consistent with the printed certificate, with potential rating shown for energy-conscious buyers.
Mortgage brokers and green finance
Green mortgage products reward EPC C or better with lower rates. The widget lets brokers surface eligibility checks during the application flow without scraping the EPC register.
How EPC bands work
The score is a number out of 100; the band is derived from the score. The widget renders both, using the exact colours from the printed EPC certificate.
A
Score 92+ · Excellent
Band A
B
Score 81–91 · Very good
Band B
C
Score 69–80 · Good
Band C
D
Score 55–68 · Average
Band D
E
Score 39–54 · Below average
Band E
F
Score 21–38 · Poor
Band F
G
Score 1–20 · Very poor
Band G

Frequently asked
What does the EPC widget show? ▾
Current and potential energy efficiency band (A–G) rendered in the official EPC certificate colours, the numeric score out of 100 for each, certificate date, floor area in square metres, and construction age band. When a property has no lodged certificate, the widget shows a clear empty state with the construction age.
Where does the EPC data come from? ▾
The MHCLG Energy Performance of Buildings Register, published as Open Government Licence data. Homedata indexes the full register for England and Wales — around 25 million domestic certificates — and refreshes nightly.
What if the property has no lodged EPC? ▾
The widget renders a premium empty state explaining that no certificate is on file, and shows the construction age band if available. This is most common for properties that have not been sold or let since EPCs became mandatory (2008 domestic, 2013 non-domestic). The rendered card is never blank.
Is the widget compatible with MEES compliance workflows? ▾
Yes. The Minimum Energy Efficiency Standard requires non-domestic rented properties to be rated E or better, with proposals to raise this to C by 2030. The band and score shown are exactly the values used by MEES enforcement.
