CIS Verification 2026: Best Practices + Free UTR Lookup

Why CIS Verification Matters

Proper verification of subcontractors is essential for Construction Industry Scheme compliance. Incorrect deductions can result in penalties and strained relationships.

Best Practices

1. Verify Before First Payment

Always verify new subcontractors before making any payments. This protects both parties and ensures correct deduction rates from day one.

2. Keep Verification Records

Maintain records of:

• Verification date
• UTR and National Insurance numbers
• Gross or net status
• Any matched/unmatched results

3. Re-verify Annually

While not strictly required, annual re-verification catches status changes and ensures you're applying the correct deduction rate.

4. Use Batch Verification

For contractors with many subcontractors, batch verification saves significant time while maintaining compliance.
