Companies within Marylebone

Newly Formed Companies in
Marylebone
this week

There have been 10 companies formed in the week from 04-08-2026 to 11-08-2026 within the W1U postcode district (Marylebone 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.

The geography of W1U is anchored by Marylebone, making the district more specific than the broader postcode area that surrounds it. The description is focused on Marylebone, so W1U is best read as a local guide to that named place rather than to a wider county or city.

For W1U, 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 6,003 companies recorded as of June 2026, W1U sits in the upper reaches of the district ranking at 111th out of 3,113. Here, we highlight newly formed companies and recent Companies House registrations associated with W1U addresses. That puts W1U well above the long tail of smaller postcode districts, while the local geography of Marylebone remains the main context.

For W1U, 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. Our newly formed companies wizard in our Dashboard allows you to filter by a range of options free of charge to get an idea of quantities, prior to deciding to purchase. We supply the full company details lodged when they filed their company when you have decided on your filter selection and choose to purchase.
