As part of UK government Open Data, the boundaries of freehold properties can be viewed online for free. Each plot is identified by a number, called the INSPIRE-ID. INSPIRE is so called as it is from an EU directive, the Infrastructure for Spatial Information in the European Community. This gives a cadastral map for the UK, similar to what other European countries have had.
The access to this map is found via the data.gov.uk website and presents a map of the Uk that you have to zoom in to get the area you want.
Click here for Mitcham (opens in a new window or tab).
Zoom in on the map by using the slider or double clicking. The map area may be blank as it takes a while to get all the data.
To get a description of the plot, make a note of the INSPIRE-ID number and do a search on the Land Registry website.
