London Borough Postcodes  

London Borough Postcodes, Metropolitan Boroughs and Non-Metropolitan Districts are divided into Wards for local elections.  The City of London has its own type of Wards based on ancient and permanent sub-divisions of the City.

This product is a lookup between every Postcode in Greater London and the Electoral Ward and Districts (Boroughs) they fall within. As Postcode boundaries and administrative boundaries bear no relation to each other, this product is ideal for those applications where you need to allocate addresses to their respective Wards and Boroughs or where you need to determine all London Borough Postcodes - the Postcodes falling within a Ward or District of the London Boroughs.

London Borough Postcode Applications

The London Borough Postcode data is ideal for relating Postcodes and address information to the respective London ward, District or Borough. Therefore the data is ideal for relating residential or business addresses to council areas for public service provision or for determining all Postcodes and addresses falling within specified Wards and Districts.

The London Borough Postcode data covers the area of Greater London.

Supply Format

The data is supplied as a Comma Separated Variable (CSV) delimited text file using double quotes by default. This field format will open very easily using almost any software application including but not limited to Excel, Word, Notepad, Access, SQL etc.  Due to the size of the file, older versions of Excel may not be an option as Excel limits any file size to around 65,000 rows / records.


The London Borough Postcode data is by default emailed at the time of order using a secure download link delivery method.  If you require the data supplied in another format then we will be more than happy to accommodate you where reasonable to do so at no extra cost.


The London Borough Postcode list is licensed annually for each user that has access to it.


The file is updated every three months and free updates will be made available to you so long as your licence remains current.
