What types of company information does Companies House provide?<\/h3>\n
The registry holds six data types that matter for commercial purposes:<\/p>\n
- \n
- Company registration details<\/strong> \u2014 name, number, incorporation date, and registered address<\/li>\n
- Standard Industrial Classification (SIC) codes<\/strong> \u2014 for industry-level segmentation<\/li>\n
- Filed accounts<\/strong> \u2014 turnover bands and balance sheet totals indicating company size<\/li>\n
- Officer names and appointment dates<\/strong> \u2014 directors and persons with significant control<\/li>\n
- Charges against company assets<\/strong> \u2014 useful for financial services teams<\/li>\n
- Confirmation statements<\/strong> \u2014 periodic filings confirming company details are current<\/li>\n<\/ul>\n
Of these, SIC codes and filed accounts carry the most weight for sales targeting. SIC codes let you segment by industry at scale, filtering to, say, all active manufacturers in a specific region. Filed accounts give you a size proxy: turnover bands and balance sheet totals in full accounts indicate whether a company sits in your target revenue range. Recent incorporations signal new market entrants who may be actively buying.<\/p>\n
Charges data, security registered against company assets, is useful for financial services teams identifying companies with existing lending relationships or capital constraints. Officer names and appointment dates are administratively useful but limited: they confirm a director exists, not their commercial role or whether they control purchasing decisions.<\/p>\n
Can you use Companies House data for sales prospecting and business intelligence?<\/h3>\n
Yes, but only as a first layer, not a complete outreach list. The registry tells you a company is legally active and what sector it operates in. It does not tell you who runs procurement, what their email address is, or whether they’re in market right now.<\/p>\n
Companies House data contains no direct contact details beyond a registered address. No email addresses, no phone numbers, and no named contacts beyond directors, and even director names don’t come with titles like “Head of IT” or “VP of Operations.” The gap between a registry record and a workable outreach sequence is significant.<\/p>\n
Think of Companies House data as the foundation, not the building. It confirms a company exists, its legal structure, and its broad financial position. Everything a sales team actually needs to start a conversation, a named decision-maker, a verified contact channel, a signal that they’re ready to buy, has to come from sources layered on top.<\/p>\n

How to Access Companies House Data Sales: Downloads, API, and Update Frequency<\/h2>\n
Companies House offers two access routes: free bulk data downloads for pipeline enrichment and a REST API for point-in-time company lookups.<\/p>\n
Book a Demo<\/a><\/div>\nWhat is the step-by-step process for bulk data downloads and API integration?<\/h3>\n
The bulk download option gives you snapshot files covering the full register, every active and dissolved company, with registered address, SIC codes, officer names, and filing history. These files suit enrichment pipelines where you’re appending data to an existing prospect list in batch, not querying individual records on demand.<\/p>\n
The REST API serves the opposite need. Register at the Companies House Developer Hub, generate an API key, and authenticate each request using HTTP Basic Auth with your key as the username and an empty password field. The three endpoints most relevant to Companies House data sales workflows are company search<\/strong> (find companies by name or keyword), company profile<\/strong> (pull registered details, status, and accounts data for a specific company number), and officer search<\/strong> (retrieve directors and persons with significant control).<\/p>\n
Bulk files demand real technical handling. The CSV exports require parsing, deduplication across multiple files, and field normalisation before they’re usable, there is no plug-and-play feed here. Sales teams without a data engineer or dedicated tooling will hit that wall fast.<\/p>\n
For researchers and analysts who need geographic context alongside registry data, the Business Census dataset via the Geographic Data Service<\/a> provides additional detail on how Companies House records map to spatial and regional business distributions.<\/p>\n
How often is Companies House data updated and how fresh is the information?<\/h3>\n
This is where the reliability problem lives. Companies have a statutory filing window, often up to nine months after their accounting reference date for annual accounts, meaning a “live” API call can legally return information that reflects a company’s position almost a year ago.<\/p>\n
Filing frequency also varies sharply by company type. Large companies with audit obligations file more frequently and with greater detail. Small companies and dormant entities file minimal information on longer cycles, creating uneven data quality across any prospect list that mixes company sizes. A director change, a new trading address, or a shift in SIC code may not appear in the register for months after it happens.<\/p>\n
Companies House Data Sales Costs Versus Commercial Data Providers<\/h2>\n
Companies House data is free to access, the real cost is the infrastructure, enrichment, and labor required to turn raw registry records into a workable prospect list.<\/p>\n
What Subscription and Pricing Options Does Companies House Offer?<\/h3>\n
Companies House publishes its bulk data products and streaming API at no charge through its free service tier [1]<\/a><\/sup>. You can pull full company records, filing histories, and officer data without paying a license fee. The cost arrives the moment you try to do something useful with it.<\/p>\n
A developer needs to build and maintain the API integration. The raw data needs cleaning, dissolved companies, dormant shells, and duplicate entries are common, and that cleaning overhead is ongoing, not a one-time task. Contact details are absent entirely from the registry, so any team using Companies House data for sales prospecting must layer in third-party enrichment tools to add email addresses, phone numbers, and decision-maker names. Data decay compounds the problem: company details change constantly, and a list built in January can be meaningfully stale by March.<\/p>\n
Commercial company intelligence platforms compress that effort into a subscription. At the budget-friendly end, tools wrap Companies House data with basic contact enrichment and a usable interface. Mid-range platforms add intent signals, verified direct contacts, and more frequent refresh cycles. Premium and enterprise solutions combine registry data with proprietary research and human verification, the closest thing to a managed Companies House data sales operation without building one internally.<\/p>\n
The trade-off is direct: free raw data plus significant internal effort, or recurring platform cost that buys back that time. The right answer depends on team size, technical capability, and how many prospects you need to work each month. A five-person sales team with no in-house developer will almost always find a commercial platform cheaper in total cost than the DIY route.<\/p>\n

Data Quality Pitfalls: What Companies House Data Gets Wrong for Sales Teams<\/h2>\n
Companies House data has four structural failure modes that make raw exports dangerous for sales outreach without a verification and enrichment layer first.<\/p>\n
What Common Pitfalls Should You Avoid When Using Companies House Data for Business Intelligence?<\/h3>\n
The registered address trap.<\/strong> A large share of UK companies file an accountant’s office or a formation agent’s address as their registered office. That address field, one of the most-used filters in Companies House data sales workflows, tells you where paperwork goes, not where the business operates. Geographic targeting built on it is unreliable from the start.<\/p>\n
Director data decay.<\/strong> Officer records reflect filings, not reality. Directors resign, get replaced, or are listed as nominees who hold the role in name only. Treating a name pulled from the register as a current decision-maker, without cross-referencing a live source, produces outreach that hits the wrong person, bounces, or damages sender reputation with active buying contacts.<\/p>\n
Book a Demo<\/a><\/div>\nDormant and shell company noise.<\/strong> The register includes thousands of entities that are legally active but commercially inert, holding companies, dormant subsidiaries, and shelf formations. Without filtering logic that screens for trading activity, these inflate prospect lists with targets that will never convert.<\/p>\n
SIC code self-reporting drift.<\/strong> Companies choose their own Standard Industrial Classification codes at incorporation and rarely revisit them. A software firm that pivoted from logistics may still be filed under a freight category. Segmenting by SIC code alone produces lists that misrepresent what companies actually do today.<\/p>\n
How Complete and Accurate Is Companies House Data for Different Use Cases?<\/h3>\n
For legal compliance checks and company verification, the register is fit for purpose. For outbound sales targeting, it is not, and the gap between those two use cases is where most teams get burned.<\/p>\n
The practical implication is direct: Companies House data requires enrichment against live commercial signals before it is safe to use as the basis for outbound activity. Platforms like Fluum pull from 100+ government and private databases precisely to layer verified, current contact signals on top of static registry data, replacing the raw-export approach with matched introductions to decision-makers who are confirmed active and reachable.<\/p>\n
Legal and Compliance Rules for Using Companies House Data Commercially<\/h2>\n
Companies House data is free to use commercially, but GDPR, PECR, and licensing rules all apply the moment you use it for sales prospecting or direct outreach.<\/p>\n
What are the licensing restrictions and terms of use for Companies House data?<\/h3>\n
Companies House publishes its data under the Open Government Licence (OGL), which permits commercial use, redistribution, and the creation of derived products. You can build a Companies House data sales tool, resell enriched datasets, or use the data in a prospecting workflow without seeking separate permission.<\/p>\n
The OGL does require attribution, you must acknowledge Companies House as the source whenever you publish or redistribute the data. It also does not grant rights over third-party content that Companies House holds but does not own, such as certain filed documents. Derived datasets you create carry your own licensing obligations on top of the OGL baseline.<\/p>\n
How do GDPR and data protection laws affect commercial use of Companies House information?<\/h3>\n
Company registration data is public, but director and officer records name real individuals, which brings them inside GDPR’s scope the moment you store, process, or contact them. Public availability does not remove the obligation to handle personal data lawfully.<\/p>\n
Using director contact details for B2B outreach may qualify under the legitimate interest lawful basis, but this is not a blanket permission. You must complete and document a balancing test showing that your commercial interest does not override the individual’s rights, and you must be prepared to demonstrate that test to the ICO if challenged.<\/p>\n
PECR adds a separate compliance layer for email and phone outreach. Even when the underlying data is legally obtained, the channel you use to contact someone carries its own rules, unsolicited electronic marketing to individuals requires either consent or a demonstrable soft opt-in relationship.<\/p>\n
Before any outreach begins, cross-reference your derived contact list against opt-out registers such as the Telephone Preference Service and against your own internal suppression lists. Skipping this step creates direct regulatory exposure regardless of how cleanly you sourced the original data.<\/p>\n
A practical compliance checklist before launching any outreach campaign built on Companies House data should cover the following steps:<\/p>\n
- \n
- Confirm the lawful basis for processing personal data (legitimate interest or consent)<\/li>\n
- Complete and document a Legitimate Interest Assessment (LIA) if relying on that basis<\/li>\n
- Suppress against the Telephone Preference Service (TPS) for phone outreach<\/li>\n
- Suppress against your internal opt-out and unsubscribe lists<\/li>\n
- Ensure your privacy notice is accessible and covers this category of data use<\/li>\n
- Retain records of your compliance steps in case of an ICO inquiry<\/li>\n<\/ul>\n
Frequently Asked Questions<\/h2>\n
Is Companies House data free to use for commercial purposes?<\/h3>\n
Most Companies House data is free to access and use commercially under the Open Government Licence. The core dataset, registered company names, addresses, officer names, filing history, and incorporation dates, is available at no cost through the Companies House API and bulk data downloads. Some enhanced data products, such as the document image service or certain analytical datasets supplied through third-party resellers, carry licensing fees or usage restrictions. Always check the specific licence attached to the dataset you download before building a commercial product on top of it.<\/p>\n
How do I find decision-maker contact details using Companies House data?<\/h3>\n
Companies House records officer names and registered addresses, but not personal phone numbers, email addresses, or direct contact details. To reach a named director, you need to cross-reference Companies House officer data with a separate contact enrichment source, whether that’s a commercial data provider, a professional network, or a platform like Fluum that pulls signals from 100+ government and private databases to surface verified decision-maker contacts. Companies House gets you the name; enrichment gets you the conversation.<\/p>\n
How often does Companies House update its company records?<\/h3>\n
Companies House updates its register continuously as filings are received and processed, new incorporations typically appear within 24 hours of registration. Annual accounts and confirmation statements are updated as companies submit them, which means some records reflect data that is 12 months old or more. For time-sensitive prospecting, treat Companies House as a structural data layer and supplement it with more frequently refreshed commercial signals.<\/p>\n
Can I build a sales prospecting list using only Companies House data?<\/h3>\n
You can build a structural list, companies filtered by SIC code, incorporation date, geography, or officer count, but it won’t be a workable sales list on its own. Companies House data tells you a business exists and who its directors are; it doesn’t tell you company revenue, headcount, technology stack, buying intent, or how to reach anyone directly. Effective prospecting requires layering Companies House structure with enrichment data, contact intelligence, and ideally a warm introduction mechanism that bypasses cold outreach entirely.<\/p>\n
What is the difference between Companies House bulk data downloads and the API for sales use cases?<\/h3>\n
Bulk downloads give you a full snapshot of the register in one go, suited to batch enrichment of large prospect lists. The API lets you query individual company records in real time, better for point-in-time lookups or CRM integrations that need to verify a specific company on demand. For most Companies House data sales workflows, bulk downloads handle list-building while the API handles ongoing verification and enrichment as new prospects enter your pipeline.<\/p>\n

<\/a><\/p>\nConclusion<\/h2>\n
Companies House data is a legitimate and often underused foundation for B2B prospecting, but it’s a starting point, not a finished pipeline. The three moves that matter: use bulk data or the API to filter companies by SIC code and filing behavior before you touch any outreach tool; always enrich officer names with a contact layer before attempting outreach; and treat the data as structural intelligence, not a substitute for relationship context.<\/p>\n
If you’re a senior sales leader or in the C-suite and want introductions to specific decision-makers, not just a list of names, talk to Aurora at Fluum and tell her exactly who you’re trying to meet. She’ll make sure you only see what’s relevant to your pipeline.<\/p>\n
