New plumbing companies in Swansea, by month
Sep 2025 – Aug 2026 · 32 in total
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 it goes.
Plumbing companies registered to a Swansea address by year of incorporation, and this year measured against the same run of months last year.
New plumbing 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.
