Caution against first registration

This is a means of protecting an interest in an unregistered estate affecting land. A caution can protect a wide variety of interests, for example, rentcharges and franchises.

For each caution there is a ‘caution title’ - a record, under a distinguishing number, of the details of the caution and of the declaration in support and of a plan showing the extent of the land affected by the caution.

A caution is not an actual registration of any estate in land. It is merely a means to trigger notification to the person who lodged the caution when an application for first registration is made.

There can be more than one caution in respect of the same property.

First registration

An application to register unregistered land.

Flood Risk Indicator

The Flood Risk Indicator is a textual result indicating flood risk to registered land.

The Flood Risk Indicator combines Environment Agency flood data with HM Land Registry property data to provide our customers with a high level indication of whether the land they are interested in, is at risk of flooding.

The result is provided on a title-by-title basis for registered properties within England and Wales.

Please see: Flood Risk Indicator

Property enquiry

This is where you enquire about a property and we try and match the details of the address that you provide against our address database.

The postal addresses in our database are originally supplied by the Post Office (from their Postal Address File). We attach information to addresses from the registration details. We also add new properties when fresh registrations are made. Additionally, we receive details of new and amended properties from the Ordnance Survey. Your enquiry is matched against our database and records of more than 20 million registrations in England and Wales.
