Find New Construction Leads Before Your Competitors Even Know They Exist
CompanyTrace tracks every newly incorporated construction company in the UK — straight from official Companies House data. Free. Instant. No signup.
The Problem With Most Lead Lists? They're Already Stale.
Paid B2B Databases
ZoomInfo, Cognism, Lusha — £500 to £2,000/month for data that's already months old. By the time a company appears there, they've been contacted by dozens of competitors.
Generic Scraped Lists
Bought a "construction leads" list? It's probably scraped, inaccurate, and full of irrelevant companies. You waste hours filtering out hairdressers and cafes before finding a single builder.
Manual Companies House Searches
Searching Companies House manually is slow, clunky, and painful. No filtering by trade. No bulk export. You'd spend all day to find what CompanyTrace shows in 10 seconds.
CompanyTrace solves this by showing you companies incorporated THIS WEEK — while they're still choosing suppliers, still setting up their websites, and still need what you sell.
Why CompanyTrace Is Different
Four reasons professionals choose CompanyTrace over every other lead source
First-Mover Advantage
See companies incorporated this week, not last year. Reach them before they've chosen suppliers, signed contracts, or even built a website. While your competitors are chasing cold leads, you're talking to companies that actually need you right now.
Construction Only — Zero Noise
Every company is filtered by 23 construction and trade SIC codes. Electricians, plumbers, roofers, builders, scaffolders — that's it. No cafés, no hairdressers, no random Ltd companies cluttering your search. Pure relevance.
Completely Free Forever
Other B2B databases charge hundreds or thousands per month. We charge £0. Why? Because this data is already public under the Open Government Licence. We just filter it, organise it, and make it searchable. You keep the money you save.
Official Government Data
Straight from Companies House — the UK government's official register. Not scraped from the web. Not crowdsourced. Not guessed. Every company number, address, and SIC code is verified and authoritative.
Hot Off the Press — Companies Incorporated This Week
These companies didn't exist a week ago. They're setting up right now. They need suppliers, services, and partners.

Frequently Asked Questions
Everything you need to know about CompanyTrace
What is Companies House?
Companies House is the official UK government register of all incorporated companies. It is an executive agency of the Department for Business and Trade, responsible for incorporating and dissolving limited companies, registering company information, and making that information available to the public. Every limited company in the UK must be registered with Companies House and file annual accounts and confirmation statements.
What are SIC codes?
Standard Industrial Classification (SIC) codes are 5-digit numbers used by Companies House and the Office for National Statistics to classify a company's primary business activities. For example, 41202 means "Construction of domestic buildings" and 43210 means "Electrical installation". A company can have up to four SIC codes, allowing them to describe multiple business activities.
How often is the data updated?
CompanyTrace refreshes its dataset regularly from the latest Companies House bulk data releases. New company incorporations typically appear within a few days of registration. Company status changes, name changes, and address updates are reflected as soon as the next bulk data snapshot is processed.
Is this data free to use?
Yes. All data on CompanyTrace is sourced from Companies House under the Open Government Licence v3.0. This licence permits you to copy, publish, distribute, and adapt the information for both commercial and non-commercial purposes, provided you acknowledge the source.
What construction SIC codes are included?

How do I search for a specific company?
Use the search box on the Search page to filter by company name, company number, postcode, or SIC code. Results update as you type. You can also click on any SIC code tag on a company profile to see all companies with that classification.
What does 'active' company status mean?
An "Active" company status means the company is currently registered with Companies House and has met its filing obligations. Other statuses include "Dissolved" (the company has been closed), "Liquidation" (the company is being wound up), "Administration" (an insolvency practitioner is managing the company), and "Active - Proposal to Strike off" (the company is at risk of dissolution).
How can I verify company information?
You can verify any company's details directly on the official Companies House website using the company number. CompanyTrace provides the company number on every profile page, along with a direct link to the official register. Always cross-check critical information such as registered addresses and filing history on Companies House before entering into business agreements.
