Quality, Representation and Bias
Bricks&Logic consolidates various national open data sources related to housing, including EPC records and Land Registry data. Additionally, in partnership with multiple estate agents, they acquire further details about properties and their rental features. In cases where original property attributes are missing, Bricks&Logic employs specialised modelling techniques to estimate these characteristics comprehensively, including sale and rental prices. However, it's important to note that these are modelled estimates that fill data gaps and could impact the accuracy of the data. The Bricks&Logic data are updated retrospectively over time as new information about property become known. These data represent outputs from models that were compiled in January 2024.
To ensure the reliability of modelled estimates, the accuracy of the predicted fields are tested by Bricks&Logic against a subset of addresses that have been described by their Estate Agent clients. This not only allows for validation of the predictions has also provided a real-world testing environment to refine the models further. Additionally, Bricks&Logic regularly update data where new information is available, using these tests to enhance the precision and accuracy of their output.
