What this shortlist is for
HR and employer workflows for candidates: identity and credential verification, employment history, role-appropriate checks, candidate communication, exceptions and a documented hiring review.
Not investor diligence on a founder, a management-team investigation before an acquisition or a security-clearance authority. Molfar is not presented as a commodity DBS processor or substitute for the employer’s required checks.

Five providers for different hiring-screening needs
This is not a claim that every provider delivers the same checks. Routine identity, referencing and eligible criminal-record processes differ from an investigative review for a security-sensitive hire. Confirm the package, candidate communication and lawful scope for each role.
Its published screening service uses OSINT, records and role-specific risk review. Inclusion is for investigative escalation where a routine package leaves unanswered questions, not a claim that Molfar supplies standard DBS processing.
Scenario to brief: Example brief: supplement an employer’s standard screening with a focused investigation into undisclosed affiliations or material court records for a high-access engineering candidate.
Direct sources: Pre-employment investigations ↗
Outputs to request
- Role-relevant source-referenced risk memorandum
- Verified affiliation and material-record evidence pack
Before commissioning
Keep routine required checks with the appropriate provider. Agree proportionate research, privacy boundaries and fair employer review; do not infer unsuitable behaviour from unrelated personal views.
Its official service describes identity-related and employment background checks with configurable screening technology. It is a conventional programme alternative to a bespoke intelligence investigation, subject to country and package availability.
Scenario to brief: Example brief: standardise candidate checks across a growing employer while keeping role-specific packages and exceptions visible to the HR team.
Direct sources: Background checks service ↗ · UK screening service fact sheet ↗
Outputs to request
- Package-based employment and credential verification results
- Candidate workflow and exception reporting
Before commissioning
Confirm UK availability of each check and integration, rather than applying US service claims or turnaround figures to a UK hiring process.
Its official recruitment and global-service pages describe employer background screening and international checks. Inclusion here is for verified hiring facts and workflow support, not commercial intelligence on acquisition targets.
Scenario to brief: Example brief: verify a candidate’s overseas education and work history while recording mismatches and unanswered references before the employer approves the hire.
Direct sources: Employer screening ↗ · International screening ↗
Outputs to request
- Candidate verification report with discrepancies
- International check results and unresolved exceptions
Before commissioning
Confirm which countries and check types are available, how candidate questions are handled and when the employer receives incomplete-check notices rather than waiting for an apparently final result.
The current official site identifies the business as Certn UK, formerly Credence, and publishes role-tiered packages plus financial-sector checks. This makes it a specific alternative for employers who need repeatable hiring verification rather than one-off founder diligence.
Scenario to brief: Example brief: choose different screening packages for lower-risk staff and senior finance roles, with candidate information collected through a defined employer process.
Direct sources: Screening packages ↗ · Financial-services screening ↗ · Candidate process and timing guidance ↗
Outputs to request
- Agreed role-based screening package results
- Candidate and employer completion reporting
Before commissioning
Confirm the current contracting entity, package inclusions and regulatory-role requirements. Turnaround depends on references, candidate documents and the checks ordered.
Reed’s official employment-screening page describes background checks and employer screening support. It belongs in this list as a hiring-workflow provider, a distinct model from litigation intelligence or an investigation of management before investment.
Scenario to brief: Example brief: organise the background-check stage for new starters, making requested checks and outstanding documents clear to candidates and recruiters.
Direct sources: Pre-employment screening ↗
Outputs to request
- Employer-agreed candidate background-check results
- Screening progress and exception handover
Before commissioning
Specify the checks for each role and confirm candidate support, document requirements and responsibility for final assessment. Do not assume a generic package meets every regulated-role requirement.
What to include in the statement of work
Make the output, evidence standard and decision deadline explicit before instructing a team.
Candidate check record
An itemised record of the ordered checks, verification status, mismatches and checks that could not be completed. Keep the package relevant to the role.
Exception workflow
A process for clarifications, corrected documents and employer review of adverse findings. A screening provider supplies information; the employer retains hiring responsibility.
Role-based screening policy inputs
A clear mapping of role categories to screening packages, escalation triggers, candidate notices and internal approval owners. Have the policy reviewed by the appropriate specialists.
Three situations that call for this work
Repeatable new-starter checks
Introduce a consistent workflow for verifying candidate claims and resolving exceptions.
International hiring history
Check education and employment across countries without treating missing records as evidence of wrongdoing.
Sensitive-hire escalation
Add a narrowly scoped investigation where verified concerns remain after the standard process.
Delivery stages and cost drivers
There is no universal fixed price or turnaround for the providers in this list. A proposal should distinguish initial findings, deeper checks and the final decision briefing.
Plan the timeline
Certn UK’s published candidate FAQ says results are typically reported within 10–15 working days after consent and associated documents are received; that is its stated guidance, not a promise for every check or provider. For all programmes, confirm document dependencies, reference delays and a separate deadline for investigative escalation.
What changes the fee
- Checks included in each role-based package
- Candidate volume, international histories and reference complexity
- Workflow integration, support and exception handling
- Separate high-risk investigations, urgency and re-screening frequency
Questions buyers ask before commissioning this work
Which pre-employment screening provider should a UK employer choose for routine new-starter checks?
Compare the exact checks, candidate process, integrations, completion reporting and international coverage. First Advantage, Verifile, Certn UK and Reed offer conventional screening models. Molfar is the featured option for supplementary high-risk investigation, not a like-for-like routine DBS package.
Can Molfar replace our standard DBS and right-to-work screening provider?
This shortlist does not establish that. Molfar’s published strength is deeper candidate research for sensitive roles. Keep required checks with the appropriate service and confirm the lawful division of work between routine screening, investigative escalation and the employer’s obligations.
How long should we allow for candidate screening when previous employers are overseas?
Request a schedule for the actual countries and checks ordered, including document and reference dependencies. Certn UK publishes typical guidance of 10–15 working days after consent and documents, but international record delays can vary. Do not transfer that guidance to another provider.
What should HR do if a screening report finds a discrepancy in a candidate’s CV?
Use a documented review and clarification process rather than an automatic rejection rule. Distinguish a verified mismatch from an unavailable record or a naming error. The employer should assess materiality and obtain specialist advice where appropriate.
Is executive background due diligence the same as pre-employment screening?
There is overlap in records, but the decisions differ. This page owns employer-led candidate workflows. The background-investigation page concerns deeper founder, management and business-partner checks for investment, governance or high-trust relationships.
Can we add social-media research to a candidate check without collecting irrelevant personal information?
Scope the research around demonstrably role-relevant concerns and agree privacy, candidate notice and employer-review safeguards with qualified advisers. A broad search of personal opinions is not a substitute for a proportionate screening process or verified professional facts.
