About

UK Energy Performance Certificates (BYOK) lets an AI assistant read your own UK Energy Performance Certificates data through the UK Energy Performance Certificates API with a key you supply (Energy Performance of Buildings Data API bearer token). Read-only: 7 tools (get_certificate, search_domestic_certificates, search_non_domestic_certificates, search_display_certificates, list_certificate_changes, list_code_tables, get_code_values). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.get-energy-performance-data.communities.gov.uk. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by UK Energy Performance Certificates. UK Energy Performance Certificates and its logos are trademarks of their owners and are used only to say which service the connector works with.

Sources: Live from the UK Energy Performance Certificates API (api.get-energy-performance-data.communities.gov.uk) with a BYOK key; documentation: https://get-energy-performance-data.communities.gov.uk/api-technical-documentation. Endpoints checked against that documentation on 2026-10-16.
