Harmonised Disclosure Template

The Harmonised Disclosure Template (HDT) is the worldwide standardised, Excel-based form that lending institutions who have been granted the Energy Efficient Mortgage Label use to disclose information on their energy efficient mortgage products.

Against this background, starting from 23 September 2025, the Final version of the HDT 2026 has been approved and published on the Energy Efficient Mortgage Label Website. The HDT 2026 has now entered a phase-in period until the cut-off date of 30 March 2026, during which issuers can use either HDT 2026 or HDT 2025. Starting from the cut-off date of 30 March 2026, only HDT 2026 will be allowed in order to be Energy Efficient Mortgage Label compliant.
