New Company Data UK: How to Access and Use It for Business Growth
Every working day, hundreds of new companies are registered with Companies House. Each one represents a fresh business that needs services, suppliers, and partners. For B2B companies that can reach these businesses early, the opportunity is enormous. But how do you actually access new company data in the UK, and what can you do with it?
This guide covers everything you need to know about sourcing, filtering, and using new company data to grow your business.
What is new company data?
New company data refers to the information filed when a limited company is incorporated with Companies House. At the point of registration, every company must provide a set of core details that become part of the public record. This includes the company name, registered address, director names and addresses, SIC codes describing the business activity, and the date of incorporation.
This data is valuable because it identifies businesses at the very beginning of their journey. A company that was incorporated yesterday is likely making purchasing decisions right now. They need an accountant, business insurance, a website, a phone system, banking, and dozens of other services. If you sell any of these, new company data puts you in front of buyers at the exact moment they are looking.
Where does new company data come from?
All new company data in the UK originates from Companies House, the official registrar. When someone incorporates a company online (which takes about 24 hours to process), the registration details become publicly available through several channels:
- Companies House website - you can search for individual companies for free, but there is no built-in way to view all companies incorporated on a given day
- Companies House API - the free REST API allows programmatic access, but has rate limits (600 requests per 5 minutes) and no dedicated endpoint for daily incorporations
- Bulk data products - Companies House publishes monthly snapshots and a streaming API for real-time filing events, but processing these requires significant technical infrastructure
- Third-party data providers - services like NewCo Data aggregate, clean, and deliver new incorporation data daily, filtered by sector
What information is included?
When a new company is registered, the following data points become available:
- Company name and company number
- Date of incorporation
- Registered office address (postcode, city, full address)
- SIC codes describing the type of business
- Director names (first name and surname)
- Director correspondence address
- Director date of birth (month and year)
- Director nationality and occupation
- Persons of significant control (shareholders with 25%+ ownership)
What Companies House does not provide is direct contact details like email addresses or phone numbers. However, the registered address and director information gives you enough to find and reach the decision-maker through other channels.
How businesses use new company data in the UK
Accountants and bookkeepers
New company directors are legally required to file accounts with Companies House and submit tax returns to HMRC. Most founders are not qualified accountants, which means they need professional help from day one. Accountancy firms that reach new companies within the first week of incorporation have a significantly higher conversion rate than those who wait.
Insurance brokers
Many types of business insurance are legally required before a company starts trading. Professional indemnity, employers' liability, and public liability insurance are all common needs. New company data filtered by SIC code lets insurance brokers target the sectors they specialise in.
Web design and digital marketing agencies
A newly incorporated company almost certainly needs a website, branding, and a digital presence. Agencies that use new company data can offer introductory packages timed to the moment a business is setting up its identity. Filtering by sector helps agencies pitch relevant portfolio examples.
Business banking and financial services
Every new company needs a business bank account. Challenger banks and fintech lenders use new incorporation data to reach founders before they commit to a banking provider. The window for winning a banking customer is narrow, so speed matters enormously.
Telecoms and IT providers
New businesses need phone systems, broadband, email hosting, and IT support. Telecoms providers use new company data to reach businesses during their setup phase, when they are actively comparing options and making quick decisions.
How to filter new company data effectively
Raw new company data is useful, but filtered data is powerful. The most common filtering methods are:
- SIC code filtering - target specific industries (e.g., SIC 41-43 for construction, 62 for IT, 56 for restaurants)
- Geographic filtering - focus on companies registered in specific regions, cities, or postcodes
- Director-level filtering - identify companies where the director has specific characteristics (e.g., first-time directors vs. serial entrepreneurs)
- Company type filtering - private limited companies are the most common, but you might specifically want LLPs or PLCs
Effective filtering turns a daily list of 2,500+ companies into a targeted list of 50-200 genuine prospects in your niche.
Manual vs automated approaches
You can access new company data manually through the Companies House website, but it is extremely time-consuming. There is no "show me today's incorporations" button. You would need to search company by company or process bulk data files yourself.
The Companies House API offers a more scalable approach, but building and maintaining an integration requires developer resources. You need to handle rate limiting, data parsing, error handling, and storage. For most businesses, the cost of building and maintaining this infrastructure outweighs the benefit.
Automated data services like NewCo Data handle the entire pipeline. We pull every new incorporation from Companies House daily, enrich the data with director details and SIC code descriptions, apply your sector filters, and deliver a clean, ready-to-use lead list to your inbox each morning.

Companies House data is public information. It is made available by the UK government specifically for public access. Using this data for legitimate business purposes, including B2B marketing and sales outreach, is lawful under UK GDPR, provided you follow the rules for direct marketing.
For email outreach, you can contact company directors at their business addresses under the legitimate interest legal basis, as long as you provide an easy way to opt out and your communications are relevant to their business needs. For postal mail, Companies House registered addresses are designed for business correspondence.
Always ensure your outreach is targeted, professional, and genuinely useful to the recipient. Spamming thousands of irrelevant companies is not just ineffective; it damages your sender reputation and wastes everyone's time.
Key takeaways
New company data in the UK comes from Companies House and includes company details, director information, SIC codes, and registered addresses. Over 2,500 companies are incorporated every working day, creating a massive daily pool of potential B2B leads. The most effective approach is to filter by SIC code and geography to create targeted prospect lists. Manual access is possible but impractical at scale. Automated services deliver clean, filtered data daily, letting you focus on outreach rather than data processing.
