Ask anything about a construction contractor
Every result is a starting point, not an endpoint. Ask a follow-up about any contractor on your list in plain English and the agents go back out and read for it, then answer with the sources they used.
Do they self-deliver groundworks or sub it out?
AnswerSelf-deliver. They advertise directly for excavator operators and list their own plant fleet on the site.
SourcesCareers page + the contractor’s own plant list
What size contracts do they actually win?
AnswerMostly between £500,000 and £4 million. Two award notices in the past year sit in that range, and the projects page lists nothing larger.
SourcesPublic contract award notices + project pages
Where is their yard, and do they own it?
AnswerA yard of about an acre on the edge of town, held by a second company with the same two directors.

Contact databases are assembled from what companies publish about themselves: professional profiles, funding rounds, tech stacks, hiring pages. Construction produces less of that than any other large sector. Work arrives through main contractors, architects, quantity surveyors and word of mouth on site, the Construction Industry Scheme pushes a large share of the workforce into self-employment, and the firm behind a twelve-person groundworks outfit is very often a private limited company with two directors, a yard and a mobile number. That model generates almost none of the web signals a profile-derived database collects. What it does generate is a set of filed accounts, planning applications, contract award notices, accreditation certificates, safety notices and vacancies that have to be filled before the next start on site. Companies House publishes the first, councils the second, Contracts Finder and Find a Tender the third, CHAS and Constructionline the fourth, the HSE the fifth, and none of those are where a contact database looks.

Frequently asked questions.
Start from the public record rather than a database. Every UK construction company files at Companies House, most public work is published on Contracts Finder and Find a Tender, planning approvals sit on local authority portals, and accreditation is listed by CHAS, Constructionline, Gas Safe Register and NICEIC. Causo reads those alongside the contractors’ own sites, so a firm with no marketing presence is as findable as one with a marketing team.
Those databases are assembled largely from professional profiles and web signals that skew heavily toward software and services. Construction is the opposite shape: there were 885,000 construction SMEs in the UK at the start of 2025, more than in any other sector, and the US Census Bureau counted 2.9 million American construction businesses with no paid employees at all. A two-director firm with a yard and a van usually has no profile to scrape, so it never enters the database and no filter will surface it.
The contractor, why it matched, the evidence behind that with its source, and the decision maker with a verified email address. You can then ask follow-up questions about any result, such as what size contracts it wins or whether its accreditations are current, and get answers with sources attached.
Yes, in plain English. None of those is a field in any contact database, so Causo works them out from accreditation directories such as CHAS and Constructionline, trade registers such as Gas Safe Register and NICEIC, published contract award notices and the contractors’ own project pages, rather than looking them up.
Watch the award and approval trail rather than a database refresh cycle. Public contract awards and framework appointments are published on Contracts Finder and Find a Tender, planning consents appear on local authority portals, and a new site manager or quantity surveyor vacancy usually follows within weeks. Causo reads all three at the moment you search, so an award notice published last month shows up in this month’s results.
It depends on the size of the firm. At a sole trader or a small limited company it is the owner, usually the person also running the job. From roughly fifteen staff upward it is more often a contracts manager, a commercial director or a plant manager, and the site manager is the person who has to live with the decision. Causo surfaces the role alongside the company so you can tell which of those you are looking at.
Yes. The sources differ by country, so Causo uses the local equivalents: in the United States that is the state contractor licence boards, municipal permit systems, SAM.gov contract awards and OSHA enforcement records, and elsewhere it is the national company registry, the permit system, the trade bodies and whatever procurement notices that jurisdiction publishes.
