St. James's
this week

There have been 18 companies formed in the week from 26-10-2026 to 02-11-2026 within the SW1Y postcode district (St. James's in South 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 South West London.

St. James's gives SW1Y its immediate geographic focus, while the wider Westminster setting helps define the district's regional character. The description is focused on St. James's, so SW1Y is best read as a local guide to that named place rather than to a wider county or city.

For SW1Y, the SW postcode context matters: The SW postcode brings the district into south-west London, an area ranging from Westminster and Chelsea to suburban neighbourhoods, parks and riverside communities.

Company registration numbers put SW1Y in a strong national position, ranking 114th of 3,113 districts with 5,910 companies as of June 2026. Company data for SW1Y brings together recent incorporations and newly formed companies associated with addresses in the district. That puts SW1Y well above the long tail of smaller postcode districts, while the local geography of St. James's remains the main context.

The result is a more rounded view of SW1Y: part local area guide, part company-registration reference.

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.
