Technical specification

Restrictive Covenants

Overview

A restrictive covenant is a contract in a deed between 2 landowners. One land owner (the covenantor), promises the other (the covenantee), not to carry out a specified act on the defined area of their land. For example, the covenantor cannot build on the land without getting consent from the covenantee first.

Restrictive covenants usually happen when somebody selling land wishes to restrict what the buyer can do with it. However, sometimes the vendor will agree to restrict their own use of land they are keeping. The obligation to comply with the covenants remains, no matter how often the land changes hands or how out of date the covenants seem to be.

Specification scope

Inclusions and exclusions

This dataset includes all registered land and property in England and Wales that have a restrictive covenant recorded against them. Due to data protection regulations, it excludes any personal data. It excludes details of what the restrictive covenant is. This information may be available in individual registers or in documents referred to on the register and retained by HM Land Registry.

Relationship to other HM Land Registry data products

The Unique Identifier (UID) will be consistent across HM Land Registry's datasets and allow relational links with other datasets with this attribute.

Address relationships

The UID represents an individual registered title and includes the property address from the register and the Land Registry Property Gazetteer address.

Data quality

The dataset is made up of elements copied from HM Land Registry's database systems via an automated process. Before we release the dataset, we check it for inclusions and exclusions through a quality control process. We try to make sure our public data is accurate but cannot guarantee it is free from errors or fit for your purpose or use.

Data capture information

Restrictive covenants are entered in the register in accordance with section 32 of the Land Registration Act 2002 and rules 35 and 72 of the Land Registration Rules 2003.

Data maintenance

The published data gives a snapshot of land and property that has a restrictive covenant recorded at the point of monthly extraction.

Data product delivery

Access to the dataset

Two files will be published from the 6th working day of the month.

The data is published in both a monthly complete file and a change only update file which shows the changes made in the dataset since the previous month.

Once the full dataset has been downloaded, the UID allows the user to maintain the data by adding the change only update to the full dataset each month. Alternatively, the user can download the full dataset again, which also contains all changes made to date.

Granting access

You'll need to create an account on the Use Land and Property Data service.

To create the account, you'll need to provide some information about yourself. We collect and hold personal and non-personal information, which may be validated, to identify who has requested the data. For more information about how HMLR handles personal data, see the Personal information charter.

There are 3 different licences for this dataset. You have to choose which licence you need based on how you're going to use the data. Once your account has been approved and you've agreed to the correct licence, you can sign in to the service to access the data.

File structure

The data is provided as a .CSV file. The data in each file will:

  • use a comma to separate each field: ',' (ASCII 44)
  • enclose all fields within double quotes: “ ” (ASCII 34)
  • send blank fields without a character between double quotes: “ ”
  • have a date format of YYYY-MM-DD. For example, 14 December 2013 will be shown as 2013-12-14
  • use UTF-8 encoding (the way characters are coded for websites)
  • have line separation removed
  • have the column heading name as the first row
  • have the row count as the last row

File name

The file names will be structured as follows:

  • Monthly full extract
  • file name: RES_COV_<FULL>_<YYYY>_<MM>.csv
  • Monthly change only update (COU)
  • file name: RES_COV_<COU>_<YYYY>_<MM>.csv

File management

The current full file and current change only update file will be available for download each month.
