How to opt out of Experian Marketing Services
Experian runs a marketing database separate from its credit reference business. Millions of UK adults are on it. Here's how to opt out under UK GDPR — and why it's not the same as your credit file.
Most people know Experian as a credit reference agency — the organisation that holds your credit history and is checked when you apply for a mortgage or a phone contract. What many people do not know is that Experian also runs a separate marketing data business, Experian Marketing Services, that holds consumer profiles on the majority of UK adults and licenses them to direct marketers, insurers, and other commercial organisations.
These are two distinct operations with different legal bases, different data, and different opt-out processes. Opting out of one does not affect the other. This guide covers the marketing database — not the credit file.
What Experian Marketing Services holds
Experian Marketing Services maintains a consumer database built from the Edited Electoral Register, public records including Companies House and the Land Registry, county court judgment data, and information licensed from third-party data providers. It also draws on data shared by credit applicants — with appropriate consent — and from retail and financial services partners.
The resulting profile typically includes your name, address history, household composition estimates, inferred income band, and marketing segment classifications. These profiles are used to target direct mail, email marketing, and digital advertising. They are also licensed to other organisations who use them for identity verification and fraud screening — a use case that is distinct from direct marketing.
Your right to opt out
Under UK GDPR Article 21(2), you have an absolute right to object to your personal data being used for direct marketing. This right admits no exceptions — Experian cannot claim a legitimate interest that overrides it. Once you exercise it, they must stop using your data for marketing purposes without undue delay.
You can also invoke Article 17 (the right to erasure) if you want your data deleted rather than simply suppressed from marketing use. In practice, for a marketing database, the distinction matters: suppression means your record remains but is flagged as do-not-contact; erasure means the record is deleted. For most people, erasure is the stronger right to invoke.
How to submit your request
Experian provides an online opt-out portal for its marketing database at experian.co.uk/privacy/consumer-information-portal. Through this portal you can:
- Request a copy of the data Experian holds on you (a Subject Access Request)
- Object to your data being used for marketing (Article 21)
- Request erasure of your marketing profile (Article 17)
When submitting, cite both Article 17 and Article 21 explicitly. Include your full name, current address, date of birth, and any previous addresses you have lived at in the past five years — Experian's database is address-linked, and records from previous addresses will not be captured by a request that only references your current address.
Experian has 30 days to respond. If they do not respond or refuse without a valid legal basis, you can escalate to the ICO.
What Experian can legitimately retain
Experian may retain some data after an erasure request where there is a separate legal basis for doing so. Credit reference data held under the Consumer Credit Act is governed by different rules and is outside the scope of a marketing opt-out. Fraud prevention data held under legitimate interests for that specific purpose may also be retained. Experian is required to explain any retention and the legal basis for it in their response.
If their explanation does not satisfy you, or if they claim a legitimate interest that you believe does not apply, you can challenge that through the ICO.
The re-listing problem
As with most UK data brokers, Experian Marketing Services re-ingests data from primary sources on a rolling basis. An erasure request removes your record from their current database, but the underlying sources — particularly the Edited Electoral Register — continue to generate new data. Depending on how Experian's ingestion cycle interacts with your opt-out flag, your record may re-appear after the next data refresh.
DataDelete monitors Experian Marketing Services on 60-day re-check cycles and resubmits removal requests if re-listing is detected. We also submit your Edited Electoral Register opt-out to your local council, which addresses the root source.
Experian and other brokers
Removing your record from Experian Marketing Services does not remove it from the organisations that have already licensed your data from them. Data purchased by a third party before your removal request remains with that third party until they receive their own removal request. This is the core reason that addressing only one broker is rarely sufficient — the data has already propagated.
DataDelete covers Experian Marketing Services alongside 22 other confirmed UK data brokers, submitting and monitoring all requests in parallel.
