A trade needs at least 30 new companies in Welwyn over twelve months before it gets a page of its own, so the 22 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.
February was the busiest month.
New companies registered to a Welwyn address each month, across all 39 trades. The busiest month was February on 12. The quietest was June on 2.
New companies in Welwyn, by month
Nov 2025 – Oct 2026 · 77 trade rows, 63 companies
Small numbers move about. At this volume a quiet month and a busy month in the same year is normal, so read the twelve-month total before you read any single month.
How far back Welwyn goes.
Companies registered to a Welwyn address by year of incorporation, across all 39 trades, and this year measured against the same run of months last year.
New companies in Welwyn, 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.
How Welwyn compares.
New companies over the last twelve months in the towns closest to Welwyn on volume. Welwyn is number 754 of the 1,076 towns counted here.
Welwyn comes with the rest of Hertfordshire: 6,893 companies, any trade, March to November 2026. Any month from £15.
Welwyn on its own has 38 companies in the months we hold, too few for a £15 list, so it is sold with the rest of Hertfordshire: every company registered in Hertfordshire's towns in March to November 2026, across every trade we count, each with its name, number, registered address, directors and trade. Every company registered, with its website, email and phone number where we can find one. Most companies this new have no website yet, so many rows will be the company, its address and its directors.
One file, every trade, every town in Hertfordshire. Any month from £15; every month we hold for £186.11, 10% off. 3p a company, £15 minimum an order. Pick one month, any mix, or everything. Selling into one trade instead? The UK-wide list for each trade.
Pay by card. Within a minute an email tells you when your file will arrive: usually within a few hours, never more than 48 hours.
