Of this week's 71: 57 operating businesses formed at their own or a home address; 0 at a mass-formation or virtual-office address; 14 property or holding companies; 53 of the 71 checked so far have no website yet.

For accountants, accounts due: 3,016 companies in Cardiff have accounts due in the next three months and are not registered at an accountant's address. They've filed trading accounts before, are current on their confirmation statement and are registered at their own address (458 within a month, 458 in one to two, 2,100 in two to three); 152 more are already overdue but not yet in strike-off. The free Monday email names five of them; the accountancy subscription has them with due date and registered office, in a weekly batch of the ones due about twelve weeks out. Register of 2026-10.

For accountants, companies that may be changing accountant: 47 established Cardiff companies moved their registered office away from an accountancy firm's address between 2 October 2026 and 30 October 2026, which can mean they've parted with that firm. The accountancy subscription names them each week, on the Something changed sheet. Counted from the office changes filed at Companies House, against the addresses where accountancy firms are registered.

What happens to them

Of the 6,161 companies formed in Cardiff between January 2022 and September 2023 at their own address, 51% were still on the register three years later and 34% had filed trading accounts, ranking 246th of 357 councils (UK: 51% and 35%; Wales: 53% and 36%). Most of the rest never traded: they missed their first confirmation statement and were struck off at about seventeen months.

What's being started here

New companies registered in Cardiff in twelve high street trades, 2019 and 2025, counting only addresses with fewer than ten companies of the same trade. Registered office, not trading address. Source: Companies House register, read 10 October 2026.

Cardiff ranks 32nd of 361 councils for the number of new high street companies in 2025.

Across the UK, the trade codes chosen by new companies rose 36% between 2019 and 2025, partly because founders now pick more codes for each company, so a rise in one trade can simply keep pace with the register. A company can choose up to four trade codes, so one company can appear in two rows and is counted in the total once for each. What Britain starts now has the national figures, the method and the caveats.

Pubs and bars here

Pub and bar sites in Cardiff registered for VAT or PAYE, as counted by the Office for National Statistics each March (UK Business Counts, SIC 56302, rounded to 5). In March 2026, 89% of them were run by a company.

Nationally there were 37,350 pub and bar sites in March 2026, down 4.6% from March 2019 and down 16.4% from 2010; the fall has run at the same pace since 2019 as in the six years before, and about one registered pub in five closed for good in each of the last two periods, the same share before and after 2019. The pubs piece has the method, the caveats and every council's figures as CSV.

Business-to-business email to a limited company or LLP is permitted under PECR without prior consent, provided you say who you are and offer an opt-out. Every row says where the address came from. No director names, no home addresses.
