Price paid data to UPRN lookup

Introduction: This dataset is one of the outputs from an Ordnance Survey funded project to link Unique Property Reference Number in OS AddressBased Plus to DLUHC’s EPC data and to Land Registry’s Price Paid Data Set. The linkage to the Price Paid data had a 96% match rate. The linkage was to create a publicly available lookup table for adding UPRNs to the price paid data set and covers PPD records from January 1995 to January 2022.

Content: The data set has three fields: PPD Unique identifier; the UPRN; and the Unique Street Reference Number (USRN). Additional information The linkage was created using a rules-based methodology, which is very labour intensive, but a more precise way of creating linkages, than other methodologies

## 概述
本数据集为英国地形测量局（Ordnance Survey）资助项目的产出成果之一，该项目旨在将OS地址基础增强版（OS AddressBase Plus）中的唯一房产参考编号（Unique Property Reference Number，UPRN），与英国住房、社区与地方政府部（Department for Levelling Up, Housing and Communities，DLUHC）的能源性能证书（Energy Performance Certificate，EPC）数据，以及英国土地注册处（Land Registry）的房产成交价数据集（Price Paid Data Set，PPD）进行关联匹配。本次与房产成交价数据集的关联匹配准确率达96%。该关联构建了可公开获取的查找表，用于为成交价数据集补充UPRN，覆盖1995年1月至2022年1月的PPD记录。

## 数据集内容
本数据集包含三个字段：PPD唯一标识符、UPRN以及唯一街道参考编号（Unique Street Reference Number，USRN）。

## 补充说明
本次关联匹配采用基于规则的方法，虽需耗费大量人力，但相较于其他关联方法，匹配精度更高。

## 使用权限与限制
本开放数据依据《开放政府许可协议》（Open Government Licence）发布，详情可访问：https://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/

房产成交价数据与UPRN的查找表即将上线。在此期间，请通过[UBDC数据申请表单](https://ubdc.ac.uk/data-services/data-services/access-our-services/)联系UBDC提交相关申请。
