London Building Stock Model 2 (LBSM 2)

The London Building Stock Model v2 provides energy efficiency data for all London homes. This includes information on EPC ratings, heating systems, insulation levels and building fabric.

This dataset represents an update of the original London Building Stock Model, and it brings together data from Energy Performance Certificates (EPCs), alongside data from other sources such as the London borough councils and the GLA. For properties that don't have data from an EPC or an alternative source, we’ve generated modelled values for these properties through machine learning. For more information on our methodology, please see this blog post.

An interactive map for this data is available here. The data from the London Building Stock Model interactive map has been made available through the data extracts below.

The current version of the London Building Stock Model v2 is based on data from October 2024.

The data contains Ordnance Survey mapping and the data is published under Ordnance Survey's 'presumption to publish'. © Crown copyright and database rights 2023
