There have been 8 companies formed in the week from 04-06-2026 to 11-06-2026 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.
