Energy label API

Request the official energy label of any Dutch address. Below you'll read how to implement the Energy label API.

Retrieve the energy labels for an address

With the Energy label API you quickly and reliably retrieve energy labels for residential and non-residential buildings throughout the Netherlands. The API processes official energy label data from EP-Online, the register of the Rijksdienst voor Ondernemend Nederland (RVO), and combines it with our powerful postcode and address platform. This way you always get the right energy label for the right address. The energy labels are updated daily to guarantee the most current information (via mutations published by RVO).

For each address, receive the current energy label (G to A+++++), historical energy labels and important energy performance data such as:

EP-1 - maximum energy demand (kWh/m² per year)
EP-2 - maximum fossil energy use (kWh/m² per year)
EP-3 - minimum share of renewable energy (%)

On the page What is my energy label you can look up the energy label of your (future) home.

Our API is ideal for real estate platforms, estate agents, appraisers and data parties that want to integrate energy label information. With every request you also get the street and city name back for easy verification.

The building_type field is only available for residential buildings. For non-residential buildings this field is null. For older energy labels, some EP data may be missing.
