Companies within Harley Street

Newly Formed Companies in
Harley Street
this week

There have been 6 companies formed in the week from 14-09-2026 to 21-09-2026 within the W1G postcode district (Harley Street in West London). Usually over 2500 companies get formed every working day across the country. If you would prefer to analyse by region, rather than this postal district, you can check how many companies are formed in West London.

W1G covers Harley Street, placing the district within Westminster and giving it a clear local identity within its wider postcode area. The description is focused on Harley Street, so W1G is best read as a local guide to that named place rather than to a wider county or city.

For W1G, the W postcode context matters: The W postcode gives the district a west London setting, with a mix of central commercial streets, residential squares, transport hubs and well-known cultural areas.

With 7,453 companies recorded as of June 2026, W1G sits in the upper reaches of the district ranking at 70th out of 3,113. Newly incorporated businesses using W1G addresses appear within Companies House records for this part of Westminster. That puts W1G well above the long tail of smaller postcode districts, while the local geography of Harley Street remains the main context.

For W1G, the geography gives useful colour to the company data, especially where the district is associated with well-known streets, neighbourhoods or centres.

Below are just a small sample of the companies formed (with the numeric parts of the address redacted with an X and not showing the postcode, so we are not advertising peoples full addresses online) but allows you to see where some of the companies have been formed.
