The families are ours, not the register's: they exist so the colour on every chart means something. A company carrying more than one SIC code can land in more than one trade, so the rows above can count the same company twice and the family total is a total of the rows rather than a headcount of companies. The grouping is set out in full on the method page, SIC code by SIC code.
March was the busiest month.
New building companies registered across the UK each month. The busiest month was March on 8,372. The quietest was December on 3,943.

Registrations dip over Christmas and pick up in the new year in almost every trade, so compare a month with the same month a year earlier rather than with the one before it.
How far back it goes.
Building and trades companies still on the register, by year of incorporation, and the like-for-like comparison underneath: the first 10 months of 2026 against the same 10 months of 2025.

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 of UK company formation takes the same problem apart across all 39 trades.

Where building firms are starting.
New building companies registered over the last twelve months, by the post town on the registered office address, or, where that office is a formation agent, by the town the company's directors run their other companies from.
London is counted as a single post town, so it is not really in the same contest as the rest of the list. It took 5.6 times as many new building companies last year as Birmingham. Leaving it in the ranking below would squash every other bar to a stub, so it sits up here on its own.
Ranked 2 to 16, without London
Bars scaled to Birmingham at 1,306, not to London
Each town above links to its busiest building trade there where that pairing has enough volume for a page, and to the town itself where it does not. Every town counted, ranked and linked.
