Dear editors and reviewers,
Thanks for your comments. I have uploaded a revised version based on the reviewers’ comments. The highlighted text shows the revisions in the new manuscript. I list the reviewers’ comments along with my reply in the first three pages in the new manuscript. Furthermore, during this open peer review, I received some feedback from Twitter. Following these comments, two new paragraphs have been added in section 4 to benefit users who need the latest versions of the raw linked data before the process of linkage evaluation and data cleaning.
Current research on residential house price variation in the UK is limited by the lack of an open and comprehensive house price database that contains both transaction price alongside dwelling attributes such as size. This research outlines one approach which addresses this deficiency in England and Wales through combining transaction information from the official open Land Registry Price Paid Data (LR-PPD) and property size information from the official open Domestic Energy Performance Certificates (EPCs). A four-stage data linkage is created to generate a new linked dataset, representing 79% of the full market sales in the LR-PPD. This new linked dataset offers greater flexibility for the exploration of house price (/m 2) variation in England and Wales at different scales over postcode units between 2011 and 2019. Open access linkage codes will allow for future updates beyond 2019.
