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.
The longest-running plumbing companies in Watford.
The list above is the newcomers. These are the plumbing companies with a Watford address that have been on the register longest and are still live, out of 180 in all. Years are counted from incorporation, so a business that traded before it became a company is older than it looks here.
New companies too: every new company in Hertfordshire, every trade (6,893 across the months we hold), or the UK list for plumbing below.
December was the busiest month.

New plumbing companies in Watford, by month
Nov 2025 – Oct 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 Watford address by year of incorporation, and this year measured against the same run of months last year.
New plumbing companies in Watford, by year
2017 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.
