B2B marketing lists in the UK typically cost £175–£350+ per 1,000 records. A good one contains verified contact details for businesses that match your target market. A bad one — which is most of them — contains whatever the broker had lying around, resold to you and a dozen competitors.
This guide covers what a good list actually contains, what you should pay, the compliance basics, and the question no list vendor will raise: whether a list is the right product for you at all.
One thing worth knowing up front. Almost everything that ranks for “b2b marketing lists” is written by a company selling them. The only exception is the ICO’s guidance on using marketing lists — the regulator, warning you to check where the data came from. That gap between what vendors say and what the regulator says is where most wasted budget lives.
What Is a B2B Marketing List?
A B2B marketing list is a set of business contact records — company names, addresses, phone numbers, email addresses, and usually a named decision-maker — filtered to match a target market. You buy one to give your sales or marketing team businesses to contact, sorted by sector, size, or location.
They come in three flavours, priced differently because the compliance and verification burden differs: email lists for cold email campaigns, telemarketing lists for phone outreach, and postal lists for direct mail. Most UK brokers sell all three, cut from the same underlying database.
That last point matters more than any feature comparison. The database is the product. The list is just a query against it — and the same query has been run for other buyers in your sector before you.
What a Good B2B Marketing List Contains
Judge a list by its fields and how recently each one was verified. Here’s the hierarchy, from the minimum worth paying for to what genuinely good data looks like:
| Tier | Fields | What it’s good for |
|---|---|---|
| Minimum | Business name, verified website/domain, location, trading status | Market sizing, direct mail, manual research |
| Good | + Direct phone number, verified email, social pages | Phone and email outreach a salesperson can start on today |
| Best | + Named owner or decision-maker, their role, their email, company size or SIC code | Personalised campaigns that don’t open with “Dear Sir/Madam” |
Two fields separate serious providers from resellers, and almost nobody volunteers them:
A verification date per record. Not “our database is updated regularly” — a date, on each row, showing when a human or system last confirmed the record was live. If the provider can’t produce this, the honest answer is that they don’t know how old their data is.
The source per field. Was the email pattern-guessed or confirmed? Is the phone number the head office switchboard or the site manager’s line? A provider who knows their data can answer per field. A reseller can’t.
Sector filtering is where generic lists quietly fail. A “construction companies UK” list built from raw SIC codes will include holding companies, dormant entities, and one-person subcontractors alongside the firms you actually want. Profession-filtered lists — a builders email list, an accountants list — verified against the register and the company’s live website are a different product from a SIC-code dump. We sell these by profession at Email Lists, so read our claims with the same scepticism — but the field checklist above applies to us too.
What B2B Marketing Lists Cost in the UK
UK pricing is quoted per 1,000 records. The benchmarks, from providers who publish rates:
| List type | Typical UK price per 1,000 | Why the difference |
|---|---|---|
| Email list | £275–£350+ | Email verification and higher decay rate |
| Telemarketing list | £300–£400+ | TPS/CTPS screening and number validation |
| Direct mail list | £250–£400 | Address accuracy; cheapest to verify |
Sources: RD Marketing’s cost guide and Data HQ’s published pricing, which puts the broad market range at £175–£350+ per 1,000 with volume discounts from around 10,000 records.
The quoted rate is not the real price. The real price is cost per usable record. If a £300-per-1,000 list was compiled a year ago and B2B data decays at 22.5% per year, you’re paying £300 for roughly 775 usable records — 39p each, not 30p. A cheaper list with older data is routinely the more expensive option once you do this arithmetic.
Anything dramatically below the benchmark range — the £50 lists on freelancer marketplaces — is scraped data with no verification and no compliance trail. The ICO expects you to check the provenance of bought lists; with those, there is none to check. We compared the main UK B2B data providers at each price tier separately, from enterprise platforms down to what an SME can justify.
Buy One or Build Your Own?
Here’s what list vendors would rather you didn’t know: the skeleton of every UK B2B marketing list is free.
Companies House publishes its Free Company Data Product — a downloadable CSV of every live company on the register, with name, registered address, SIC code, and incorporation date. Zero cost. That’s the raw material most UK list brokers start from.
Build your own if you need a small, specific list — say, 200 care homes within 30 miles — and someone on your team can spend a day filtering the register and checking websites. For a list you’ll call personally over three months, that day of work beats any purchase.
Buy if you need volume, direct contact details, or speed. The register gives you companies, not people. It has no email addresses, no phone numbers, no decision-makers. Enriching 2,000 records by hand is weeks of work, which is the actual service you’re paying a provider for — and why buying a B2B email database is a different decision with its own failure modes, which we’ve covered separately.
The trap is the middle path: buying a raw register export dressed up as a “marketing list”. If a provider’s records contain nothing you couldn’t get from the free Companies House download, you’re paying £300 per 1,000 for a filter someone ran in ten minutes.
The Freshness Problem Nobody Prices In
B2B contact data decays at about 2.1% per month — 22.5% per year — and the measured range runs as high as 70.3% in high-turnover sectors. Email addresses decay at 23–30% per year. Phone numbers change at around 18%.
People change jobs, businesses close, companies get acquired, offices move. Every one of those events silently kills a row in your spreadsheet.
You feel the decay in two places. First, deliverability: campaigns run on non-validated data typically see 5–7% bounce rates, against 1–2.5% with clean data — and sustained bounces at that level damage your sender reputation, hurting every campaign that follows. Second, morale: salespeople who spend their morning reaching disconnected numbers stop trusting the list by lunchtime, and a list your team doesn’t trust is worthless whatever it cost.
So before comparing prices, ask every provider the same question: when was this segment last verified — not compiled, verified? Then ask what happens when a record turns out to be dead. A provider confident in freshness offers replacement records. One who isn’t offers excuses.
GDPR and PECR in Two Minutes
The compliance picture for UK B2B marketing is friendlier than most SME owners assume, with two traps. The short version:
Emailing limited companies is allowed without consent. PECR’s consent rule for marketing email does not apply to corporate subscribers — limited companies and LLPs. You can email them cold, lawfully.
Trap one: sole traders don’t count. Sole traders and most non-LLP partnerships are treated as individual subscribers under PECR, which means they need consent — the same rule as consumers. A list mixing limited companies with sole traders is a list where part of your outreach is unlawful by default. Ask providers how they screen for this.
Trap two: UK GDPR still applies to the people. A named individual’s work email is personal data. You need a lawful basis to process it — for B2B marketing, that’s normally legitimate interests, documented in a short assessment — plus you must tell people where you got their data and honour opt-outs. Legitimate interests only stretches to people whose role makes your message relevant.
Practical due diligence on any bought list: get the provider’s ICO registration number, ask when and how the data was collected, and get the sole-trader screening answer in writing. That’s the 90-second version — the full picture, including legitimate interests assessments and what to do when someone objects, is in our guide to compliant B2B data.
When a Marketing List Is the Wrong Product
Everything above assumes a list is what you need. Sometimes it isn’t — and this is the part no list vendor will tell you.
A marketing list answers who exists. It cannot answer who needs you right now. Every business on it is at a random point in its buying cycle, which is why cold outreach from static lists converts at low single digits while trigger-based prospecting generates 20–35% response rates. The list isn’t underperforming. It’s doing exactly what a list does: telling you who, and nothing about when.
If your service maps to a public trigger event — a restaurant failing a hygiene inspection, a care home registering with the CQC, a planning application being filed — then timing data beats volume data, and a signal feed will outperform any list at any price. If there’s no such event in your market, a well-verified list is the right tool, and the checklist above will get you a good one.
Most businesses need something in between: not 10,000 raw records, but a few hundred from a verified lead list matching a tight spec, fresh enough that the phone numbers connect.
B2B Marketing Lists: FAQs
How much does a B2B marketing list cost in the UK?
£175–£350+ per 1,000 records from mainstream providers. Email lists run £275–£350 per 1,000, telemarketing data £300–£400+, direct mail £250–£400. Judge on cost per usable record, not the headline rate.
Are bought B2B marketing lists legal under UK GDPR?
Yes, when handled correctly. Cold email to limited companies is permitted under PECR, and legitimate interests covers the UK GDPR side for relevant, named individuals — provided you document it, disclose your source, and honour opt-outs. Sole traders need consent.
What should a B2B marketing list include?
Minimum: business name, verified domain, location, working phone number. Good: a named decision-maker, role, verified email, and company size. Best: a verification date on every record.
How quickly does a B2B marketing list go out of date?
Around 2.1% of records die per month — 22.5% per year, worse in high-turnover sectors. A twelve-month-old list has lost roughly a quarter of its value before the first call.
If you’re about to buy a list, run the checks in this guide first: verification dates, source per field, sole-trader screening, ICO registration, monthly terms. Any provider worth paying will pass all five without flinching.
