Best Company Database Providers in UK — 2026

Best for: Businesses wanting local map-based leads with phone/email filters across 195 countries.

Launched in 2021 and operating worldwide from scrap.io, Scrap.io scores 9.2 for turning Google Maps into a genuine lead source. Its index covers 200 million places, filterable by category, location, phone number and email presence across 195 countries, which makes it unusually effective for the kind of local prospecting that UK agencies, trades suppliers and field sales teams actually run. On the Basic yearly plan, the cost works out at $0.0035 per lead — among the lowest unit prices in this rating — and the platform reports being trusted by 50,000+ professionals. Named figures associated with the service include Julien Arcin, Sébastien Tissier, Mélodie Marfouk, François Dufaur-Boidin and Sarah Bobtchev-Melin. The catch is structural rather than technical: map listings describe premises, not corporate entities, so a Scrap.io export shows where a business trades and how to reach it, but little about turnover, group structure or registry status. Exporting also requires a paid monthly subscription starting at €49 per month, meaning a team that prospects only twice a year still carries twelve months of billing, or buys in bursts instead. For high-volume, geography-led campaigns — every dental practice in Greater Manchester, every independent garage in Yorkshire — that trade-off is easy to accept. For firm-level research or enriching an existing CRM, it's less comfortable.

Best for: UK businesses needing targeted, GDPR-compliant B2B direct mail, telemarketing and email contact lists with decades of consultancy support

Marketscan has supplied British B2B data since 1982, making it the longest-established name in this rating and, for many UK marketers, the default choice. Its database at marketscan.co.uk covers 3 million+ UK businesses, and its Megabase™ product puts 7 million B2B decision-makers within reach of a single selection. Scoring 9.1, the service is built around list supply rather than self-serve software. Specialists help define a selection and deliver it for direct mail, telemarketing or email use, treating GDPR compliance as part of the brief rather than an afterthought. That consultancy layer is the real product here. Decades of work across UK sectors show in the targeting options, and buyers who need defensible provenance for a postal or telemarketing campaign tend to value a supplier able to explain where each field came from. Pricing reflects the model: £250 plus VAT per 500 contacts, or roughly 50p per contact before any enrichment, well above the per-lead economics of the two platforms ranked ahead. Scope is the other limit. Marketscan is a United Kingdom specialist by design, so campaigns reaching into Europe or North America need a second source, and list-based delivery suits planned quarterly campaigns better than continuous, iterative prospecting. Within British borders, though, few providers match its depth of decision-maker coverage.

Best for: UK businesses needing GDPR/PECR-compliant postal, telemarketing or email lists for targeted B2B/B2C campaigns

Prospect360 has worked as a UK B2B and consumer marketing data broker since 2003, making it one of the longer-standing names in this ranking. Its database covers roughly 1.9 million UK company sites, alongside access to over 6 million verified UK business contacts and records — a figure that reflects the broker model, where contact depth matters more than raw company counts. Pricing runs per record, from £0.10 to £1.50 for B2B data. That structure works well for buyers who already know which segment they want and how many records they need: a tightly filtered postal or telemarketing list of a few thousand names can be costed to the penny before anything is committed. Compliance is where the brand positions itself most clearly. Lists are supplied for GDPR and PECR-compliant postal, telemarketing and email campaigns — a practical concern for any UK team running outbound into business and consumer audiences alike. Scope is the trade-off. Coverage stops at the UK, so cross-border prospecting needs a second source, and the per-record model gets pricey at the top of its range once volumes climb. Still, for campaign-led buyers working domestically, two decades of brokerage experience and six million contact records amount to a serious starting point.

Best for: UK businesses needing company credit scores, risk checks, and lead lists

Endole, founded in 2014, occupies an unusual spot in the UK market: it treats credit risk and sales intelligence as a single product rather than two separate ones. The database holds more than 7 million companies, paired with 21M+ verified contacts for reaching decision-makers, so one record can answer both whether a firm is worth selling to and whether it's safe to invoice. That dual purpose is largely why it's listed here. Sales teams often treat creditworthiness as somebody else's problem until an unpaid invoice turns up; Endole puts credit scores and risk checks in the same interface as its lead lists. Ubaidul Chowdhury is among those publicly named in connection with the platform. Access runs on subscription, starting at £25 per month. For a finance or credit control function checking counterparties continuously, a recurring fee fits naturally. For an outbound team that only needs a burst of records once a quarter, it's less comfortable — the meter keeps running whether anyone logs in or not. Coverage stays domestic throughout. Seven million UK companies is substantial depth for a single market, and the risk scoring is harder to replicate than a plain contact list. Anything beyond British borders, though, falls outside what Endole was built for.

Best for: UK-focused sales and marketing teams needing telephone-verified business data for telemarketing, direct mail and compliant outbound campaigns.

Market Location sells human-verified B2B business and contact data for the UK, and verification is really the whole pitch. Its file of around 1.8 million records is checked by people rather than assembled purely through automated scraping, which is why 4,000+ UK businesses running telemarketing and direct mail trust it. Pricing is a one-time charge of roughly £150 per 1,000 emails. Nothing accumulates in the background, so a campaign can be costed as a single line item — handy for agencies billing a client for a defined piece of work, or for in-house teams working to a fixed quarterly budget. The case for telephone-verified data is strongest where a wrong number costs real money. Direct mail landing at a closed office, or a caller working through dead switchboard lines, burns hours a verified file would have saved. Market Location's method is built to target exactly that kind of waste. Reach is where it falls short. The database is UK-only and comparatively small at 1.8 million records, so narrowly defined segments — a given industry, in a given region, at a given headcount — can thin out fast. At £150 per thousand emails, repeated campaigns against overlapping segments also add up quicker than volume-priced alternatives.

Best for: Businesses needing structured European company registration, sales, and employee data for market research, CRM enrichment, or competitor analysis within Europe.

HitHorizons is a worldwide B2B company database built on European business registration data. Founded in 2019, it holds records on more than 80 million companies, and its stated specialty — European lead generation — shapes how that data is structured: registration details, sales figures and employee counts arranged in a form that drops easily into market research or a CRM. For anyone working the British market, one figure stands out. The UK accounts for 16.38% of all companies in the database, or 7,928,336 records — a share large enough that UK prospecting doesn't feel like an afterthought inside a continental dataset. That volume supports competitor analysis, territory mapping and segment sizing without constant gaps. The trade-off sits at the edges of the map. HitHorizons concentrates on 50 European countries, so a UK team also chasing leads in North America or Asia will need a second source alongside it. Within Europe, though, the registry orientation is a real advantage: figures come from official filings rather than inference, which matters for CRM enrichment, where a wrong employee band quietly distorts scoring. Seventh place here is a comment on reach, not on craft. HitHorizons does one region thoroughly, and teams whose pipeline stops at the European coastline will find little reason to look further.

Best for: Businesses needing verified UK company credit, ownership and compliance data

Global Database is a UK business intelligence and company verification service, founded in 2015, with records on more than 5 million UK companies. Its focus lies in verification rather than sheer volume: the platform links to Companies House and over 300 official UK registries, so ownership, credit and compliance details trace back to filed records rather than scraped approximations. Nicolae Buldumac and Vitalie Aremescu are named publicly among the people behind the company. That registry connection explains why the service earns a place on a UK list at all. Credit checks, beneficial ownership queries and supplier due diligence are tasks where a single stale directorship entry can derail a deal; a direct line to official sources shortens the distance between a query and a defensible answer. For compliance teams, that lineage often matters more than headline record counts. The limits, though, are just as clear. Coverage stops at the United Kingdom, which makes the database a verification layer rather than a prospecting engine for teams selling abroad. Licensing adds further friction: access is sold annually, upfront and on a quote basis, so costs are committed before the data has even been tested against real search queries. Eighth place reflects scope and commercial terms, not accuracy. Within British verification work, Global Database remains a serious option.
