House Price per Square Metre in England and Wales, 1995-2021

This house price per square metre dataset was created on 1/4/2021 and is based on the LR PPD, Domestic EPCs and NSPL downloaded on the same day. It covers over 18 million transactions with 218 variables in England and Wales between 1/1/1995 and 26/2/2021. 16 of the 104 variables come from the LR PPD, 84 variables come from Domestic EPCs, one variable (lad21cd) from NSPL and three variables (i.e.id, classt, priceper) are created by the first author. Before the data linkage, a unique identifier (id) is created for all the unique EPCs after removing the individual lodgement identifier (i.e. LMK_KEY variable). During the data linkage, a variable named classt is created to identify 1:1 and 1:n linkage relationships. After the data linkage, a derived house price per square metre variable (i.e. priceper) is obtained through dividing the transaction price paid in the LR PPD with the total floor area variable in the EPC dataset. The NSPL (May 2021 version) is used to assign the local authority unit (lad21cd) to the house price per square metre dataset. During the data linkage process, the transactions in the LR PPD assigned as category B (Additional Price Paid entry) and other property types are removed. This version of the dataset unlike the previous version can be described as ‘uncorrected’ as we have not removed transactions with any improbable price per square metre values (e.g. total floor area values are null, 0). This uncorrected version of the data will offer the most flexibility for researchers. Researchers are recommended to clean the uncorrected version according to their research need.
