Prospect list guide
How do you build a B2B prospect list?
To build a B2B prospect list, define your ideal customer profile, find real companies that match it, verify each one against an official register such as Companies House, identify a decision-maker, and write personalised outreach. Prospecting.Business automates all five steps from your website URL, from £49 for 10 verified-checked leads.
What are the steps to build a prospect list?
- 1
Define your ideal customer profile (ICP)
Write down what you sell, the problems it solves, and which companies feel that pain most. Industry, company size, geography and buying triggers all narrow the field. Your own website copy is usually the best starting point — it already describes who you serve.
- 2
Find real companies that match the profile
Sources include LinkedIn searches, industry directories, the Companies House register for UK businesses, and AI tools that search for companies matching your ICP. Aim for named, specific companies — not just categories.
- 3
Verify each company exists and is trading
For UK companies, look each one up on Companies House: check the registered name, that the status is active (not dissolved or in liquidation), the registered office and the listed directors. This single step removes most dead entries from a prospect list.

Identify a decision-maker and their contact details
Director records on Companies House, company websites and LinkedIn identify who to contact. Be honest with yourself about data quality: an email found on the company’s own website with valid mail records is verified; a guessed pattern like firstname@company.com is an estimate and should be treated as one.
- 5
Write personalised outreach for each prospect
Generic blasts get ignored. Reference what the company does and why your offer is relevant to them specifically. One tailored paragraph beats ten template lines.
- 6
Track outcomes and refine the profile
Export your list to a CSV or CRM, record replies, and feed what you learn back into the ICP. Prospecting is a loop, not a one-off task.
Bought lists vs generated lists — which works better?
| Bought (resold) list | Generated list | |
|---|---|---|
| Relevance | Broad filters; many records won’t fit your offer | Matched to an ICP modelled from your own website |
| Freshness | Static databases age; firms dissolve and staff move on | Generated at the moment you run the analysis |
| Registry checks | Rarely checked against Companies House | Every UK company checked on the live register |
| Exclusivity | Same records sold to many buyers | Built for your business only |
| Outreach effort | You research and write every email | A personalised cold email drafted per lead |
| Cost model | Per 1,000 records, often with minimum orders | One-off packages: 10/£49, 15/£69, 20/£99 |

Prospect list FAQs
How long does it take to build a prospect list manually?
Researching, registry-checking and finding contacts for a single well-qualified prospect typically takes 10–20 minutes by hand, so a 20-company list is often a full day’s work. Prospecting.Business automates the same steps — ICP modelling, company search, Companies House checks and email drafting — and delivers a 10-lead list from £49.
Is it better to buy a prospect list or build one?
Building (or generating) a list targeted to your ideal customer profile almost always outperforms buying a resold database extract, because relevance drives reply rates. Resold lists are cheaper per record but are static, rarely registry-checked, and shared with other buyers. Generated lists cost more per lead but are fresh, specific and auditable.
How do I verify UK companies on my prospect list?
Search the Companies House register (find-and-update.company-information.service.gov.uk) for each company. Confirm the registered name matches, the status is active, and note the registered office and directors. Prospecting.Business runs this check automatically against the live Companies House API and badges leads with a confirmed active match as registry-verified.
How many prospects should be on my first list?
Start small: 10–20 well-qualified prospects with personalised outreach will teach you more than 500 generic records. Prospecting.Business packages match this: 10 leads for £49, 15 for £69, or 20 for £99, each with a drafted cold email included.
Can AI build a prospect list for me?
Yes — Prospecting.Business does exactly this. Paste your website URL, and the AI models your ideal customer profile, finds matching companies, checks UK companies against Companies House, and drafts a personalised cold email per lead. Contact details carry honest source labels, and unconfirmed details are shown as estimates, never passed off as verified.
