“Background Checks Reveal Everything About Someone” – What’s Possible

“Background Checks Reveal Everything About Someone” – What’s Possible

The bottom line: Background checks are a valuable investigative tool, but they do not reveal everything about a person. What a check can uncover depends on the type of check, the sources searched, the reason for the check, and UK data protection law. There is no single database that contains every piece of information about every person. Different checks access different records, and many records are only available with the subject’s consent or a specific legal basis.

Where This Myth Comes From

The phrase “background check” sounds exhaustive. It suggests a process that examines a person’s entire background, leaving nothing hidden. Employers talk about “running a background check” as though it were a single action that reveals a complete picture. In truth, a background check is not one thing but a collection of different searches, each accessing different types of information, each governed by different rules.

The myth is also fed by the American experience, where credit reports, criminal records, driving records and even social media screening are commonly bundled into pre-employment checks. UK law is far more restrictive about what information can be obtained and how it can be used, particularly in employment contexts.

What Background Checks Can Reveal

Identity verification: Confirming that someone is who they claim to be is the foundation of any background check. This typically involves verifying name, date of birth, address history and right to work in the UK. Electoral roll data, credit reference agency records, and document verification services are used for this purpose. Our background check service begins with this step.

Criminal record checks: The Disclosure and Barring Service (DBS) operates three levels of criminal record check in England and Wales: basic, standard and enhanced. A basic check shows unspent convictions only. Standard and enhanced checks show spent and unspent convictions, cautions, reprimands and warnings. Enhanced checks can also include information from local police that the chief officer considers relevant. Standard and enhanced checks are only available for specific types of role (such as positions working with children or vulnerable adults). Learn more about our criminal record check services.

Employment history: Previous employers can confirm dates of employment, job title and, in some cases, reason for leaving. They are not obliged to provide a reference, and many organisations limit references to factual information only. Our reference verification service handles this process professionally.

Qualifications and professional memberships: Educational institutions can confirm whether a degree or diploma was awarded. Professional bodies can confirm membership status. Investigators regularly find discrepancies between claimed and actual qualifications, particularly for senior roles.

Directorships and company associations: Companies House records show current and previous directorships, company secretaryships and major shareholdings. This is publicly available information that can reveal business interests, conflicts of interest and commercial activities.

County court judgments and insolvency: CCJs, individual voluntary arrangements (IVAs) and bankruptcy orders are recorded on public registers. These are relevant for financial roles, directorships and credit-related positions.

Sanctions and watchlists: Checks against international sanctions lists, politically exposed persons (PEP) lists, and adverse media databases are standard in financial services and regulated industries.

What Background Checks Cannot Reveal

Spent criminal convictions (without a higher-level check): Under the Rehabilitation of Offenders Act 1974, most criminal convictions become “spent” after a specified period. A basic DBS check will not show spent convictions. Even enhanced checks do not show all convictions: the filtering rules exclude certain old and minor offences. This means a background check may not reveal a person’s complete criminal history.

Medical records: An employer cannot access an individual’s medical records through a background check. Medical information can only be obtained with the individual’s explicit consent, typically through an occupational health assessment. The Access to Medical Reports Act 1988 gives individuals the right to see and comment on any medical report provided by their GP to their employer.

Credit history (without consent): Running a credit check on an individual requires their consent. While some employers in financial services roles do include credit checks in their screening process, this must be disclosed to the candidate and they must agree. A PI cannot run a credit check on someone without their knowledge.

Private activities and relationships: A background check searches records and databases. It does not reveal who someone is dating, what they do at weekends, what their political views are, or how they behave in private. Information of this nature requires active investigation (such as surveillance or enquiries), not a database search.

Foreign criminal records: UK criminal record checks only cover offences in the UK. If someone has a criminal history in another country, a standard DBS check will not reveal it. Obtaining overseas criminal records is possible in many jurisdictions but requires separate applications to the relevant foreign authority, and the process is often slow and incomplete.

Social media activity (without limits): While some screening providers include social media checks, these are limited to publicly visible content and must comply with data protection principles. An investigator cannot access private accounts or create fake profiles to view protected content. The legal and ethical boundaries of social media screening are still developing, and employers who rely on social media checks without proper policies risk discrimination claims.

The Role of Consent and Purpose

UK data protection law requires that personal data be collected for a specified, explicit and legitimate purpose. In employment screening, this means the employer must tell the candidate what checks will be carried out, obtain their consent where required, and only process information that is relevant to the role.

An employer hiring for a bookkeeping role has a legitimate interest in checking financial probity and relevant criminal history. The same employer has no legitimate basis for checking the candidate’s medical history, relationship status or political affiliations.

For non-employment purposes, the rules still apply. A corporate investigation into a potential business partner, for example, can examine publicly available business records, court filings and adverse media. It cannot access the individual’s personal bank accounts, phone records or private correspondence.

The DBS System Explained

The DBS check system is often misunderstood. Many clients assume they can request an enhanced DBS check on anyone for any reason. This is not the case. The level of check available depends on the role or purpose:

Basic DBS check: Available to anyone. Shows unspent convictions and conditional cautions only. Costs £18 and is typically returned within two weeks. Any employer can request this for any role, but the candidate must apply for it themselves.

Standard DBS check: Available for specific roles defined in the Rehabilitation of Offenders Act 1974 (Exceptions) Order 1975. Shows spent and unspent convictions, cautions, reprimands and final warnings. Cannot be requested for a general office role.

Enhanced DBS check: Available for roles involving close contact with children or vulnerable adults. Includes everything on a standard check plus any relevant information the local police force chooses to disclose. The enhanced check with barred lists adds a check of the children’s and adults’ barred lists.

Requesting a higher level of check than the role justifies is not permitted and constitutes a data protection breach.

Getting the Most From a Background Check

The value of a background check depends on asking the right questions and using the right level of check for the situation. A basic identity and employment verification is appropriate for most standard roles. A more detailed investigation, including directorships, adverse media, sanctions screening and international checks, is appropriate for senior appointments, regulated positions and business partnerships where the financial exposure is high.

At UKPI, we offer background checks at multiple levels, from pre-employment screening through to business partner due diligence for high-value transactions. We will explain what each level of check covers, what it costs, and what limitations apply.
