Companies House is one of the most open corporate registers in the world. Anyone can download the free basic company data snapshot, filter by Standard Industrial Classification (SIC) code, or pull newly incorporated UK limited companies by town and postcode. Yet every Companies House export shares the same gap: it contains no website URL, no email address, and no telephone number.

Worse still, a company's registered office address on Companies House is often an external accountant or formation agent rather than the company's trading premises. Searching Google manually for hundreds of company names and copying domains past pages of directory listings quickly stalls any research or outreach project.

This guide explains how our UK Company Website Enricher on Apify turns raw UK company names and registration numbers into verified corporate websites, confidence scores, contact page URLs, and published contact channels.

Why raw Companies House lists are hard to match by hand

  • Directory clutter: Searching a UK limited company name returns dozens of company-register mirrors (such as Companies House itself, Endole, Pomanda, Company Check, DueDil, and OpenCorporates) before the company's actual trading website.
  • Trading names versus legal names: Many businesses register as ABC Holdings Ltd or XYZ Services (UK) Limited while operating online under a cleaner brand domain.
  • Similar names across different industries: Without cross-checking the 8-character Companies House registration number or registered locality in the website footer, privacy policy, or terms page, naive search scrapers frequently attach the wrong company's website.

How the UK Company Website Enricher verifies official domains

When you feed a batch of UK companies into the UK Company Website Enricher, the tool performs a multi-step verification pipeline for each company:

  1. Normalises the legal name: Strips suffixes such as Ltd, Limited, PLC, and LLP while preserving distinguishing words and locality hints.
  2. Excludes directory and aggregator domains: Automatically filters out company registries, financial profile directories, social media homepages, and news portals.
  3. Inspects candidate websites for verification signals: Checks the homepage, contact page, privacy policy, and footer for the exact 8-character Companies House registration number, matching legal entity name, UK postcode or town, and UK domain suffix (.co.uk, .uk, .org.uk).
  4. Calculates a confidenceScore and extracts contact channels: Assigns a clear verification score and extracts the canonical domain, dedicated contact page URL, published email addresses, telephone numbers, and official social links.

Output schema fields (JSON, CSV, and Excel)

Each enriched company row includes:

  • companyName – Input company name from Companies House or your CRM.
  • companyNumber – 8-character Companies House registration number (if supplied or discovered on the site).
  • websiteUrl – Verified official homepage URL.
  • canonicalDomain – Normalised root domain (for example komossolutions.com) for easy CRM deduplication.
  • confidenceScore – Numeric score (0 to 1) indicating the strength of the match, backed by matchSignals (such as exact company number match in footer).
  • contactPageUrl – Direct URL to the company's Contact Us or Enquiry page.
  • emails – Published business email addresses found on the homepage or contact page.
  • phones – Published UK telephone numbers found on the website.
  • linkedInUrl, xUrl, facebookUrl – Official company social media profiles linked from the website.

Step-by-step: How to enrich a batch of UK companies

  1. Export your source list: Download a CSV from Companies House Advanced Search (filtered by SIC code, incorporation date, or town) or export unenriched UK accounts from your CRM.
  2. Open the Actor on Apify: Go to UK Company Website Enricher on Apify.
  3. Paste or upload your companies: Provide the company names along with optional registration numbers and postcodes/towns for maximum accuracy.
  4. Run and export to CSV, Excel, or JSON: Click Start. Once the batch completes, export the enriched dataset directly as CSV, Excel (.xlsx), or JSON, or trigger it automatically via the Apify API, Make, or Zapier.

  • Commercial planning applicants → Website enrichment: Track commercial planning applications with the UK Planning Applications Scraper, then enrich the applicant or agent company names.

Frequently Asked Questions

Why does Companies House data not include company websites or email addresses?

Statutory filings at Companies House only require a company's legal name, 8-character registration number, SIC codes, incorporation date, officer details, and registered office address (which is frequently an accountant's office). Companies are not required to file their website domain or contact email address.

How does the UK Company Website Enricher avoid returning directory sites like Endole or DueDil?

The enricher excludes known company directory and credit-reference aggregators, then inspects candidate domains for matching legal names, Companies House registration numbers in the website footer or privacy policy, and UK address or postcode signals to compute a confidenceScore.

How much does the UK Company Website Enricher cost?

Pricing is pay-per-result at $0.004 per company ($4.00 per 1,000 companies). There is no monthly subscription fee, and Apify's free monthly usage credit covers hundreds of company enrichments every month at no cost.
