Newly Formed Companies in the Slough Area
Slough gives the SL postcode area its main identity, but the area is better understood by looking at the places it brings together. Among the names that give the area its shape are Burnham, Littleworth, Bray, Bray Wick, Colnbrook, Datchet and Farnham Common.
The SL area covers Slough, Windsor, Maidenhead, Gerrards Cross and surrounding Berkshire and Buckinghamshire districts. Its identity is shaped by the M4 corridor, Heathrow's influence, Windsor Castle, Thames-side towns, business parks, logistics and commuter connections into London.
Company registrations are not spread evenly across SL; districts such as SL1, SL6, SL3, SL2, SL4 account for a larger share of activity, while other places provide the wider geographic setting.
For anyone reviewing recently formed companies by postcode area, SL provides a useful geographic grouping. As of June 2026, SL sits among the more active UK postcode areas for company registrations, ranking 47th out of 128 with 45,854 companies.
The ranking places SL comfortably within the more active group of UK postcode areas, while its individual places explain the local character behind the figures.
When a company is registered, its registered office address is the publicly visible location of the company and the company has to legally be able to receive post at this address. Over 2,000 companies every day (sometimes over 3000) get formed. These are in England, Scotland, Wales and Northern Ireland.
We analyse whether a registered office has a valid UK postcode that we can get grid co-ordinates for distance calculations and make sure the company has not closed down since it formed. You can then contact these people in the Slough (SL) area, who may be interested in receiving your marketing message offering your services under the legitimate interest rules of GDPR (assuming you are marketing to companies who you feel have a potential interest in your services, either geographically or by category). Marketing is by post because it is a brand new company that won't have a business telephone number or business email address (and even if they have, its not part of the data collected and made available by Companies House)
Slough is made up of the following towns and villages
