Newly Formed Companies in the Cardiff Area
Cardiff gives the CF postcode area its main identity, but the area is better understood by looking at the places it brings together. Its character can be seen through places including Whitchurch, Thornhill, Cardiff city centre, Cathays, Grangetown, Canton and Llanishen.
The CF area is centred on Cardiff and parts of South Wales, including the capital's civic core, Cardiff Bay, Cathays, Roath, Llandaff and surrounding towns. Government, sport, media, universities, retail, docks heritage and valley connections all form part of the area.
Districts such as CF14, CF24, CF10, CF11, CF23 give CF much of its company-registration weight, while the surrounding places add local variety.
Companies House records linked to CF postcodes sit alongside the area's towns, districts and local landmarks. As of June 2026, CF sits among the more active UK postcode areas for company registrations, ranking 19th out of 128 with 70,274 companies.
Compared with many other postcode areas, CF has a substantial company presence, making its geography useful context rather than background detail.
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 Cardiff (CF) 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)
