London Boroughs
by Postcode

London Boroughs  

London Boroughs, 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 London Borough by Postcode 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 have no relation to each other in the normal world, this London Borough by Postcode 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 the Postcodes falling within a Borough, Ward or District.

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.
