Company names, numbers and incorporation dates come from the Companies House register and 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, below.
March was the busiest month.
Monthly registrations of construction companies in Swansea. The busiest month was March on 21. The quietest was June on 6.
New construction companies in Swansea, by month
Sep 2025 – Aug 2026 · 170 in total
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 it goes.
Construction companies registered to a Swansea address by year of incorporation, and this year measured against the same run of months last year.
New construction companies in Swansea, by year
2017 to 2026 · 2026 counts January to August 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 Swansea compares.
New construction companies over the last twelve months in the towns closest to Swansea on volume. Swansea is number 58 of the 415 towns with enough construction registrations for a page.
What else started in Swansea.
New companies registered to a Swansea address over the last twelve months, by trade. The colour on each card is the trade family. The Swansea page carries all 39 of them.
