The 50 newest in the 1 November 2026 register file.
Straight from the Companies House register, newest first, across all 39 trades. Every company number links to its own record there, and every trade links to the full list for Cardiff.
Names, numbers and incorporation dates are free to reuse under the Open Government Licence. What the register does not carry is a way to contact any of them. That is the part we sell.

A trade needs at least 30 new companies in Cardiff over twelve months before it gets a page of its own, so the 14 trades below that line are listed without a link. A company carrying more than one SIC code can appear in more than one trade, so the rows add up to more than the number of companies behind them.
The busiest month was the latest one.
New companies registered to a Cardiff address each month, across all 39 trades. The busiest month was October on 274. The quietest was August on 190.
New companies in Cardiff, by month
Nov 2025 – Oct 2026 · 2,787 trade rows, 2,267 companies
Registrations dip over Christmas and pick up in the new year almost everywhere, so compare a month with the same month a year earlier rather than with the one before it.
How far back Cardiff goes.
Companies registered to a Cardiff address by year of incorporation, across all 39 trades, and this year measured against the same run of months last year.
New companies in Cardiff, by year
2015 to 2026 · 2026 counts January to October only
Older years undercount. The register only holds companies that still exist. Anything formed in an earlier year and since dissolved has dropped off it, so the further back the chart goes the more it undercounts. That alone makes every trade look like it is growing. Some of the rise here is real growth and some of it is simply that recent companies have had less time to close. The long view works through it in full.
