List of construction companies in the UK: short answers.
How many construction companies are there in the UK?
495,101 live companies are on the Companies House register under SIC code 41100, or a code starting 412 or 43, as of 1 November 2026. 58,096 were registered in the last twelve months. Sole traders and ordinary partnerships are not on the register, so there are more construction businesses than this.
Can I buy a list of construction companies with email addresses?
Yes. The file holds every construction company registered in the months you pick, from March to November 2026, at 3p a company, £15 minimum an order. After you pay we look for each one's website, email and phone number. Most companies this new have no website yet, so many rows will be the company, its address and its directors.
What does each row contain?
The company name and number, the date it registered, its full registered address, its named directors and its trade, then its website, email and phone number where we find them.
Can I email a new construction company without its consent?
Yes, if it is a limited company. The ICO allows marketing emails to corporate bodies without prior consent; say who you are and offer a way to opt out. Every company in our lists is a limited company.

The 50 newest in the 1 November 2026 register file.
Newest first across the towns in the source files. A town links to its full construction list when that page exists, otherwise to the broader town page. Each company number links to its own Companies House record.
Names, numbers and incorporation dates 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.

New construction companies in the UK, by month
Nov 2025 – Oct 2026 · 58,096 in total
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.
Construction companies on the register by year of incorporation, and this year measured against the same run of months last year.
New construction companies in the UK, by year
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 works through it in full, across all 39 trades.
Where they're starting up.
Every town with a page of its own for new construction companies: 427 of them, covering 83% of the UK total for the trade. The rest are spread thinly across towns too small to count reliably.
Towns come from the post town on the registered office address, except where that office is a formation agent: those companies are counted in the town established from their directors' other companies, or not counted at all. A town needs at least 30 new construction companies in twelve months before it gets a page, so the rows above do not add up to the national total. How towns are worked out.
