Every plumber listed on VerifiedPlumbers.co.uk goes through a structured verification process before approval — and is re-verified every year to maintain standards.
We check identity, qualifications, business legitimacy and real-world reputation — not just sign-ups.
Identity & Location Verification
1. Photo Identification Check
We confirm the individual is who they claim to be using a third-party ID verification process.
2. Proof of Address Check
We verify the operating address of the individual.
3. Business Address Verification
We confirm the registered or trading address of the business.
Qualifications & Compliance
4. Qualification Check
We verify relevant qualifications required for the work being offered.
5. Accreditation Verification
Registrations such as Gas Safe are checked directly against official registers.
6. Certification Validity Check
We confirm certifications are active, current and not expired.
Business Legitimacy
7. Company Registration Check
We confirm the business is properly registered where applicable.
8. Active Trading Status Check
We verify the business is currently active and operating.
9. Strike-Off Risk Check
We check for any active or pending strike-off notices.
10. Company History Review
We review trading history for consistency and stability.
11. Director Status Check
We check for disqualified or banned directors linked to the business.
Financial & Operational Signals
12. Insolvency & Bankruptcy Screening
We screen for indicators of financial instability that could affect job completion.
Reputation & Behaviour Monitoring
13. Open-Source Reputation Check
We review publicly available information for red flags, including media and public records.
14. Cross-Platform Feedback Score Tracking
We collect, verify and record feedback scores from across the web — not just one platform.
15. Review Pattern Analysis
We analyse review trends over time to detect recurring issues, complaints or abnormal behaviour.
Platform Integrity
16. Duplicate & Identity Match Check
We prevent suspended or rejected trades from rejoining under new identities or business names.
