London Business Directory with SIC Codes and Local Authority Data

A 600MB Excel file lists London businesses with company name, address, postcode, local authority, and SIC code. The Greater London Authority created this cut from the UK Companies House Free Company Data Product using a postcode filter, published on 1 May 2018. Each entry represents a financial accounts submission, so the number of entries exceeds the number of distinct businesses.
