Data Brokers UK

Data Brokers UK, trading as Prospect360 (prospect360.co.uk), is a UK-based data list broker specialising in GDPR-compliant B2B and B2C marketing databases for direct mail, telemarketing, and email campaigns. The company positions itself as a supplier of marketing contact data, not a traditional BPO or outsourced service operation, but its service portfolio extends into execution-side activities that overlap with telemarketing support, email broadcasting, and data cleansing, making it relevant to buyers sourcing outbound marketing infrastructure in the UK market.

At its core, Prospect360 operates as a data intermediary. It works with a curated set of list owners to source and supply contact records across business, public sector, and consumer segments. The company claims access to over 6 million verified contacts and records across the UK, with a stated minimum 95% accuracy guarantee on data supplied. Whether that guarantee is underwritten by a formal SLA or is simply a policy statement is worth confirming directly, I would ask for a written accuracy guarantee and a clear remedy process if records fall below that threshold.

The business data offering covers a wide range of commercial sectors. The site lists specific datasets including chartered accountants, pubs, management consultants, builders and trades, butchers, charities, dentists, driving schools, education providers, estate agents, farming businesses, manufacturing contacts, marketing managers, mortgage brokers, car dealers, opticians, and photographers, giving a sense of the breadth of sector coverage rather than just vertical specialisation. Buyers can search by sector or specify their audience profile and let Prospect360 source the closest match. The public sector arm targets UK public sector organisations and their key decision-makers, which is a distinct dataset often harder to source accurately elsewhere. Consumer data is available as geographically targeted postal and telephone records.

Data is supplied across three primary channels: postal (addressed to named decision-makers for direct mail), telemarketing (telephone data, TPS-scrubbed), and email (personal B2B email addresses for named senior-level contacts). The emphasis on personal, named contacts at senior level, rather than generic company email formats, is a meaningful differentiator if the data actually delivers on it, this is the kind of claim worth testing with a sample before committing to a large list purchase.

Beyond data supply, Prospect360 offers an email marketing and broadcasting service, meaning buyers can hand off the deployment of email campaigns rather than just purchasing a list. The site also references landing page production and copywriting, making the company something of a campaign execution partner for outbound marketing, not just a raw data vendor. This is useful context for small and mid-sized businesses that want a single supplier to handle list sourcing and campaign delivery without assembling separate vendors.

On the data services side, the company offers TPS cleansing (checking telephone numbers against the Telephone Preference Service register, a legal requirement before calling consumers in the UK), data cleansing more broadly, and data appending (adding missing fields to an existing database). These services are relevant to businesses that already hold a customer or prospect database and want to enrich or sanitise it rather than buying a new list outright.

GDPR compliance is cited prominently throughout the site. For UK buyers, this is a practical necessity rather than a marketing point, buying non-compliant contact data exposes the buyer to ICO enforcement risk, not just the data provider. Prospect360 claims its data is GDPR-compliant and ready to use from day one. I would want to understand specifically what lawful basis the data is processed under (legitimate interest, consent, or other), whether the supplier documentation covers that basis, and how recently the data was verified. These questions matter because GDPR compliance in data brokerage is a chain of custody issue, the buyer inherits liability if the sourcing is weak.

The company is also WCAG 2.1 AA compliant, which means its web platform meets web accessibility standards. That is a minor operational detail but reflects some investment in platform standards.

Contact is by phone (01276 69 11 99) and email, with a UK area code suggesting a Surrey or Hampshire base, though the website does not explicitly state an HQ address in the research available. The phone number prefix (01276) is associated with Camberley, Surrey.

Who fits this vendor well? UK-based SMEs and mid-market businesses running outbound B2B or B2C marketing campaigns, direct mail, telemarketing, or email, who need a compliant, pre-built contact list rather than building their own database from scratch. It also suits buyers who want a single supplier to handle both list sourcing and email campaign execution. Businesses operating in any of the named sectors above will find pre-built lists available; buyers in more unusual niches should expect a sourcing conversation rather than an off-the-shelf pull.

The tradeoffs to be clear-eyed about: Data Brokers UK is a list broker, not a managed outbound calling or campaign management BPO. If you need agents making calls, managing conversations, and reporting on qualified leads, this is not the right vendor. The value here is upstream, sourcing accurate contact records, and for execution-heavy campaigns, you would pair this with a separate telemarketing or BPO provider.

I would verify the following before purchasing: the specific recency of data refresh cycles (how often records are updated), the exact remedy when data falls below the 95% accuracy guarantee, whether the consent or legitimate interest documentation is transferable to the buyer, what the minimum order size or spend is, and whether sample data is available to quality-test before buying in volume. For telemarketing data specifically, confirm TPS cleansing is applied to the supplied data at point of delivery, not just at time of collection. For email data, confirm it meets the ICO's current interpretation of GDPR for direct marketing to business contacts.

Bottomline: Prospect360 is a legitimate data supply and campaign support business for UK outbound marketing. For buyers who need compliant, sector-specific contact lists with optional execution support, it is a reasonable starting point. For buyers expecting end-to-end telemarketing campaign management, it is only part of the solution.
