16 new construction companies
registered in Swansea, August 2026.

170 over the last twelve months, every one named below with a link to its Companies House record. That is a new competitor, or a new neighbour, one every 2 days. 12 registered in the last 30 days to 25 September 2026, 5 this week (provisional).

Snapshot 1 September 2026, monthly, not live. Counted by registered-office post town with formation-agent addresses taken out, so it runs lower than a raw feed. How it is counted.

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.

Building and trades · Twelve months

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

Previous months August 2026

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.

2017 to 2026

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

Complete years 2026, part year
January to August 2026 119 New construction companies in Swansea so far this year
Same months, 2025 110 Up 8% year on year
2025, the last full year 161 Against 52 in 2017

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.
