What's in the database
The file combines company identifiers, address information and contact fields for business research. Company, email and phone totals measure different things: they do not mean that every company has every contact field populated. Review the sample before planning an import or estimating how much additional research your team needs.
The table below sets out the included fields and the limits of the file. It is a company-level database, not a directory of named buyers. Revenue, employee numbers and decision-maker details are not included.
| Field | What's included |
|---|---|
| Company name | Company name |
| Registry number | Company registry number for matching records |
| Address | Address including city and postcode |
| City | Included within the address information |
| Region | Not included as a separate field; use city and postcode for location filtering |
| Industry code | Industry code; a separate industry description is not confirmed |
| Employees | Employee count is not included |
| Revenue | Revenue and turnover are not included |
| Phone | Phone numbers; check availability in the sample |
| E-mail addresses; check availability in the sample | |
| Website | Not included |
| Board members | Not included |
| Decision makers | Not included |
| Legal form | Company legal form |
| Registration date | Company registration date |
Filters you can use in Excel
Apply Excel filters after downloading the file to build a shortlist around your target market. These are spreadsheet operations, not features of an online search tool. Keep an untouched copy of the original file and work on a separate sheet when sorting, removing records or adding research.
- Region: use city and postcode to select locations within your sales territory. A separate region column is not included.
- Industry: filter the industry code column to identify relevant sectors. Check what each code represents before making your selection.
- Size: employee count and turnover are not in the file. You cannot filter directly by company size without adding suitable data yourself.
- Legal form: select the company types that fit your offer and exclude those outside your intended market.
- Founding date: filter by registration date as the available reference for company age. Registration does not necessarily mark the start of trading.

Who uses the database?
Sales, marketing and recruitment teams can use the file to organise company research. The following examples are illustrative workflows, not customer results or promises of campaign performance. A listed business still needs to be assessed for relevance, and contact availability does not establish permission to send marketing.
Sales: prepare a territory shortlist
Example: an equipment supplier filters industry codes and postcodes, then uses registry numbers to remove existing accounts. The sales team researches the remaining businesses before deciding whether a call or email would be relevant and lawful.
Marketing: plan sector-specific messaging
Example: a business services team groups companies by industry and location to plan different campaign messages. Before sending anything, it checks recipient types, applicable marketing rules and its suppression records rather than treating the whole file as a mailing audience.
Recruitment: research potential employers
Example: a recruitment agency selects companies in its specialist sector and investigates their hiring activity separately. The file helps identify organisations to research; it does not contain vacancies, employee counts or the names of hiring managers.
Is using the database legal?
Buying a business database does not automatically make every use lawful. UK GDPR can apply where records identify individuals, including some business email addresses and sole-trader information. You remain responsible for choosing a lawful basis, giving required privacy information and handling objections.
B2B legitimate interest may support some processing after a documented assessment of purpose, necessity and the impact on individuals. It is not blanket permission to email. Under PECR, the rules differ for corporate subscribers and individual subscribers, including sole traders and some partnerships.
Check the rules for your intended recipients and channel before outreach. Identify the sender, provide a clear opt-out and maintain suppression records. For calls, check applicable preference services and previous objections. Seek qualified advice if your planned campaign or lawful basis is unclear.
Prepare the file before outreach
Separate company selection from contact selection. First decide which businesses fit your offer; then review the available contact details and whether using them is appropriate. Match registry numbers against existing accounts, remove duplicates where needed and keep internal notes separate from the original data.
A sample helps you judge structure, but it cannot establish the deliverability of every address in the full file. Validate the records you intend to use and avoid assuming that an email address belongs to a particular role. For other markets, browse all business email lists.
Frequently asked questions
What does the uk b2b email list include?
The file includes company name, registry number, legal form, address with city and postcode, email, phone, industry code and registration date. It covers 1 374 260 companies, with 1 683 996 e-mail addresses and 1 262 796 phone numbers. These are separate totals, not a guarantee of complete contact details for every company.
Can I filter the uk company email list by turnover?
No. Turnover, revenue and employee count are not included, so the file does not support direct filtering by financial performance or workforce size. You can filter the available columns in Excel, including industry code, city, postcode, legal form and registration date. Size-based selection requires additional information from another suitable source.
Can I download UK business contacts in Excel?
Yes. The database is supplied in XLSX and CSV formats, which you can open in Excel. Download the free 50-row sample first to check the layout and how the columns import. Preserve registry numbers and postcodes correctly, and use a working copy when sorting records or adding your own research.
How much does a UK email database cost?
The full UK country file is available from 199 € as a one-time purchase, without a subscription. A free 50-row sample is available before you buy. Use it to check whether the included fields meet your needs, especially if your workflow depends on information such as turnover or named contacts that is not included.
Does the UK contact database include decision makers?
No. Decision makers and board members are not included. The database provides company-level records and email and phone fields, rather than a directory organised by individual job title. If you need a purchasing manager, director or hiring contact, you will need to carry out separate research before choosing an appropriate contact route.
Can I use UK business email addresses for marketing?
That depends on the recipient, the data and your intended use. UK GDPR and PECR may both apply, and legitimate interest does not override electronic marketing requirements. Check whether recipients are corporate or individual subscribers, provide required privacy information and opt-outs, and respect objections. Purchasing the file does not itself provide consent.
